The Fred Hutchinson Cancer Research Center began in 1975, with critical help from Washington State's U.S. Senator Warren Magnuson.
Fred Hutch quickly became the permanent home to Dr. E. Donnall Thomas, who had spent decades developing an innovative treatment for leukemia and other blood cancers. Thomas and his colleagues were working to cure cancer by transplanting human bone marrow after otherwise lethal doses of chemotherapy and radiation. At the Hutch, Thomas improved this treatment and readied it for widespread use. Since then, the pioneering procedure has saved hundreds of thousands of lives worldwide.
While improving bone marrow transplantation remains central to Fred Hutch's research, it is now only part of its efforts. The Hutch is home to five scientific divisions, three Nobel laureates and more than 2,700 faculty, who collectively have published more than 10,000 scientific papers, presented here as a full bibliography.
NOTE: From 1995 to 2009 I served as the Hutch's vice president for information technology — hence my interest in the organization. Although my role was in the admin division, if you dig through this bibliography, you will find a couple of papers with me as an author.

Circulating Neoantigen- and Viral Oncoprotein-Specific CD8+ T Cells Share a Transcriptional Signature.
Cancer immunology research, 14(1):22-31.
Tumor-specific CD8+ T cells in blood seem to be important for and predictive of response to anti-PD-1 therapies. However, as most tumor antigens are unique to a given patient, the identification of tumor-specific CD8+ T cells is not routinely feasible. In this study, we characterized polyomavirus-specific CD8+ T cells from the blood of 17 patients with virus-driven Merkel cell carcinoma. We identified a 98-gene signature [Signature of Peripheral Tumor-specific CD8+ T cells (SPoTT)] that discriminated circulating tumor-specific CD8+ T cells from other T cells in immunotherapy-naïve patients. We observed profound transcriptomic differences among tumor-specific CD8+ T cells from blood versus those from tumor. In validation cohorts of Merkel cell carcinoma, as well as neoantigen-driven cancers, the signature of peripheral tumor-specific CD8+ T cells was able to identify viral oncoprotein- and neoantigen-specific CD8+ T cells with both sensitivity and specificity above 75%. We also tested a previously described 151-gene signature (NeoTCRPBL) trained on neoantigen-specific CD8+ T cells and found it was able to recognize Merkel cell polyomavirus-specific T cells with a sensitivity of 66% and a specificity of 88%. These findings show that circulating tumor-specific CD8+ T cells share fundamental characteristics across diverse tumor antigen types. More broadly, insights into antitumor T cells gained from virus-driven cancers are also likely to be relevant in mutationally driven cancers.

Pre-diagnostic immunological markers of bacterial translocation and liver cancer risk: A nested case-control analysis of 12 prospective cohorts.
International journal of cancer, 158(7):1801-1812.
The gut-liver axis may play an important role in hepatocarcinogenesis. However, limited prospective research has explored associations with liver cancer risk. We conducted a nested case-control study based in 12 prospective cohort studies from across the United States, which included 867 cases of liver cancer and 867 matched controls. We measured bacterial translocation markers, specifically immunoglobulin (Ig) A, IgG, and IgM against lipopolysaccharide and flagellin; soluble CD14 (a co-receptor for lipopolysaccharide); and lipopolysaccharide-binding protein. Multivariable conditional logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI) between bacterial translocation marker concentrations per doubling in concentrations and liver cancer risk. Lipopolysaccharide-binding protein concentrations were most strongly associated with higher liver cancer risk (OR per doubling in concentrations: 1.48, 95% CI: 1.23-1.79). Concentrations of anti-flagellin IgA (1.13, 1.01-1.28) and IgG (1.13, 1.01-1.28), anti-lipopolysaccharide IgG (1.20, 1.01-1.42), and soluble CD14 (1.12, 1.01-1.24) were also associated with liver cancer risk. When analyses were separated into hepatocellular carcinoma (HCC, N = 436 cases) and intrahepatic cholangiocarcinoma (ICC, N = 110 cases), no evidence of heterogeneity was observed except for lipopolysaccharide-binding protein concentrations, which were positively associated with HCC (1.77, 1.34-2.33) but not ICC (0.67, 0.37-1.22; p-heterogeneity = .003). Associations did not differ by time to liver cancer diagnosis or other subgroups. These findings support the role of gut barrier dysfunction in hepatocarcinogenesis, necessitating further research to understand the complex interplay among the mechanisms and risk factors disrupting the gut barrier, microbiota, and liver cancer.

Nurse endoscopists: a rational response to rising rates of young-onset colorectal cancer in Aotearoa New Zealand.
The New Zealand medical journal, 138(1624):76-86.
Young-onset (<50 years) colorectal cancer (YOCRC) has been increasing in Aotearoa New Zealand since the birth cohort born around the mid-1950s. Possible responses include education and public health measures, none of which are likely to make a major impact in the foreseeable future. Many YOCRCs are presenting at late stages with predominantly distal cancers. Our current National Bowel Screening Programme (NBSP), screening people 60-75 years, was introduced with inadequate resources; as a result, some colonoscopy services have been moved from symptomatic cases to screening, resulting in diagnostic delays and poorer outcomes. Extending screening to 40 or 45 years will markedly increase the need for follow-up colonoscopies and stretch services beyond breaking point. Sigmoidoscopy is associated with a substantial and sustained reduction in risk of distal colorectal cancer incidence and mortality. As there are too few endoscopists for the existing workload, increasing the nurse endoscopist workforce is a rational step. Initial training would focus on flexible sigmoidoscopy (FS) and concentrate on symptomatic patients <50 years. Steadily increasing nurse endoscopist numbers will contribute to management of the rising incidence of YOCRC. Without disrupting the NBSP or putting much extra strain on need for follow-up colonoscopies, nurse-led FS clinical services can expand to anyone with relevant symptoms and, as a longer-term goal, eventually become part of an expanded screening programme that could include one-off FS at age 50. If we are agreed that this is essential, training and service must be adequately funded and accompanied by a public advocacy campaign to ensure sufficient resources.

National Cancer Institute's Working Group on Biochemically Recurrent Prostate Cancer: Clinical Trial Design Considerations.
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 43(34):3672-3683.
PURPOSE: Biochemical recurrence (BCR) of prostate cancer (PCa) after definitive surgery and/or radiation (including salvage strategies) is a burgeoning area of clinical research inspired by ultrasensitive next-generation imaging. Most phase III trials in PCa have focused on metastatic disease, defined by conventional imaging. Despite the emergence of new imaging, clinical trial principles from metastatic studies will not optimize future BCR trials.
METHODS: A Working Group convened at the National Cancer Institute on November 13, 2024 (NCI BCR WG). Key areas of discussion included nomenclature, baseline criteria for data capture, imaging considerations, delineation of high-risk populations to be targeted for trial development, requirements of metastasis-directed therapy (MDT) or hormonal therapy, quality-of-life considerations, and potential study end points.
RESULTS: The NCI BCR WG defined the novel term "prostate-specific membrane antigen (PSMA)+BCR" to identify the emerging concept of recurrent PCa identifiable only on PSMA positron emission tomography (PET), overlapping with BCR and distinct from metastatic hormone-sensitive PCa as traditionally defined by conventional imaging. The WG suggested defining high-risk BCR with a prostate-specific antigen doubling time of ≤6 months, regardless of PET findings. The WG provided recommendations for baseline data capture and imaging requirements. Neither systemic therapy nor MDT were considered mandatory for control arms. The WG also discussed novel end points and quality-of-life metrics in this disease space.
CONCLUSION: These discussions should inform future clinical BCR trials in this distinct disease space relative to metastatic disease defined by conventional imaging. The NCI BCR WG strongly advocates that future trials explore deintensification of treatment to minimize toxicity in this relatively indolent disease state.

Osimertinib Plus Savolitinib in Patients With EGFR-Mutated Advanced NSCLC With MET Alterations After First-Line Osimertinib: Clinical Outcomes, Safety, and Biomarker Analysis: A Brief Report.
Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer, 21(2):318-327.
INTRODUCTION: The ORCHARD (NCT03944772) study was conducted to characterize resistance mechanisms and identify optimal treatments after progressive disease (PD) on first-line osimertinib. We report results from the osimertinib plus savolitinib module.
METHODS: Patients with EGFR-mutated NSCLC with PD on first-line osimertinib with MET gene amplification (≥4 copies of MET over tumor ploidy) per next-generation sequencing of a post-progression biopsy received osimertinib plus savolitinib. Primary end point was investigator-assessed objective response rate (ORR). Secondary end points included progression-free survival, duration of response, overall survival, and safety. Correlation of ORR with baseline molecular alterations was an exploratory analysis.
RESULTS: A total of 32 patients were enrolled; all had tumors with MET amplification. At primary analysis cutoff (January 2023), confirmed ORR was 47% (80% confidence interval [CI]: 34-60). Median duration of response was 14.5 months (95% CI: 5.6-18.7). Median progression-free survival was 7.6 months (95% CI: 3.2-15.9). There was a trend toward increased ORR in patients with high MET gene copy number (≥10 versus <10). Furthermore, 14 patients (44%) had grade 3 or higher treatment-emergent adverse events; most often pneumonia (n = 3; 9%). At final database lock (May 2024), 20 patients (63%) had died; median overall survival was 20.7 months (95% CI: 9.9-34.8).
CONCLUSIONS: Osimertinib plus savolitinib demonstrated encouraging clinical benefit in patients with EGFR-mutated advanced NSCLC and MET amplification after PD on first-line osimertinib. Safety was consistent with profiles of the individual drugs.

abstract = {INTRODUCTION: The ORCHARD (NCT03944772) study was conducted to characterize resistance mechanisms and identify optimal treatments after progressive disease (PD) on first-line osimertinib. We report results from the osimertinib plus savolitinib module.
METHODS: Patients with EGFR-mutated NSCLC with PD on first-line osimertinib with MET gene amplification (≥4 copies of MET over tumor ploidy) per next-generation sequencing of a post-progression biopsy received osimertinib plus savolitinib. Primary end point was investigator-assessed objective response rate (ORR). Secondary end points included progression-free survival, duration of response, overall survival, and safety. Correlation of ORR with baseline molecular alterations was an exploratory analysis.
RESULTS: A total of 32 patients were enrolled; all had tumors with MET amplification. At primary analysis cutoff (January 2023), confirmed ORR was 47% (80% confidence interval [CI]: 34-60). Median duration of response was 14.5 months (95% CI: 5.6-18.7). Median progression-free survival was 7.6 months (95% CI: 3.2-15.9). There was a trend toward increased ORR in patients with high MET gene copy number (≥10 versus <10). Furthermore, 14 patients (44%) had grade 3 or higher treatment-emergent adverse events; most often pneumonia (n = 3; 9%). At final database lock (May 2024), 20 patients (63%) had died; median overall survival was 20.7 months (95% CI: 9.9-34.8).
CONCLUSIONS: Osimertinib plus savolitinib demonstrated encouraging clinical benefit in patients with EGFR-mutated advanced NSCLC and MET amplification after PD on first-line osimertinib. Safety was consistent with profiles of the individual drugs.},

Identifying Key Questions and Challenges in Microchimerism Biology.
Advanced science (Weinheim, Baden-Wurttemberg, Germany), 12(48):e14969.
Microchimerism research has recently gained renewed attention despite known existence of these rare cells for decades. Fetal and maternal microchimeric-derived cells may have functional capabilities, and are increasingly associated with both beneficial and adverse health outcomes. Yet, establishing the role of microchimerism in health has been largely constrained methodologically and theoretically. The Microchimerism, Human Health, and Evolution Project address these challenges by calling on 29 leading microchimerism experts to put forth key research questions that can substantially advance the field. Seven major categories are identified: function and mechanism; microchimerism in interventions, treatment, and transplant; mapping "generational microchimerism"; evolution; microchimerism detection; appropriate experimental model systems; and definition of microchimerism. Identifying these questions - and continuing to find answers - will be crucial for advancing the knowledge of microchimerism in health and disease.

Low bone mineral density and pain impact in adults with sickle cell disease.
Blood advances, 10(3):748-758.
Low bone mineral density (BMD) is a prevalent skeletal finding in sickle cell disease (SCD), but its clinical consequences are poorly understood. We hypothesized that low BMD, independent of osteonecrosis (ON), would associate with pain in adults with SCD. In the SCD Bone Pain study, 53 ambulatory adults (64% females; mean age, 38 ± 11 years; 66% hemoglobin [Hb] SS/Sβ0 thalassemia) underwent dual-energy X-ray absorptiometry scans of their lumbar spine, hip, forearm, and whole body. They also completed the Adult Sickle Cell Quality of Life Measurement Information System pain impact questionnaire. Twenty-three participants (43%) had low BMD, defined as lumbar spine, total hip, or femoral neck BMD z scores of -2 or less. In multivariate linear regression, lumbar spine BMD z scores significantly changed by +0.31, -0.29, -0.14, and -1.3 for every unit increase in Hb, indirect bilirubin, and white blood cell count, and with crizanlizumab use, respectively. Pain impact T-scores significantly decreased (worsened) by 6.0 and 6.5 with reduced estimated glomerular filtration rate and chronic opioid therapy but increased (improved) by 3.8 for every unit increase in serum phosphate. The median [interquartile range] pain impact T-scores were significantly lower in participants with low BMD and ON (38.3 [37.4, 40.1]) than those with either low BMD (49.5 [43.6, 54.4]; P = 3 × 10-5) or ON (52.7 [45.3, 57]; P = 2 × 10-4) alone. Whether sickle cell-related low BMD results from impaired bone formation and/or accelerated bone loss remains unclear. Understanding how low bone density, with or without ON, mediates SCD pain warrants further investigation. This trial was registered at www.clinicaltrials.gov as #NCT05283148.

Variations in Mental Distress Among Caregivers of Individuals With Chronic Illnesses and Comorbid Cognitive Impairment.
American journal of preventive medicine, 70(4):108165.
INTRODUCTION: This study was aimed to examine the rates of mentally unhealthy days and frequent mentally unhealthy days among caregivers of patients with cancer, heart disease, mental illness, and Alzheimer's disease and related dementias on the basis of caregiving intensity and how cognitive impairment in non-Alzheimer's disease and related dementias caregiving moderates these relationships.
METHODS: Data from 22,550 caregivers in the 2019-2023 Behavioral Risk Factor Surveillance System were used to explore the relationship between caregiving intensity, mentally unhealthy days, and the presence of cognitive impairment. Zero-inflated negative binomial regressions assessed the associations of caregiving intensity on mentally unhealthy days, and logistic regressions examined the patterns in frequent mentally unhealthy days, controlling for demographics and survey weighting.
RESULTS: Caregivers of individuals with mental illness reported the highest frequent mentally unhealthy days (27.53%), followed by caregivers of those with cancer (20.3%), heart disease (18.57%), and Alzheimer's disease and related dementias (17.82%). Increased caregiving intensity correlated with higher mentally unhealthy day rates, particularly among caregivers of patients with cancer, heart disease, and Alzheimer's disease and related dementias. Caregivers of those with cancer showed increased mentally unhealthy days when moderating for cognitive impairment. Higher caregiving intensity was linked to increased frequent mentally unhealthy days in the caregivers of patients with cancer and Alzheimer's disease and related dementias, with cancer caregivers showing more frequent mentally unhealthy days when moderating for cognitive impairment.
CONCLUSIONS: Caregiving intensity affects mental health outcomes differently across illnesses. Tailored support is needed for caregivers, especially those providing care for individuals with comorbid cognitive impairment.

Back to school: a qualitative study evaluating a community-informed COVID-19 risk communication intervention for rural elementary school children and their families.
Translational behavioral medicine, 15(1):.
BACKGROUND: ReOpening Schools Safely and Educating Youth (ROSSEY) was a cluster randomized controlled trial of a risk communication intervention for COVID-19 prevention to promote safe return to school among students in a rural, agricultural community.
PURPOSE: This qualitative study evaluated the implementation of a risk communication intervention and a school district's COVID-19 testing program through parent focus groups and interviews with school staff and students.
METHODS: Parents (n = 37), students (n = 19), and school staff (n = 14) from seven schools that received the intervention shared their experience via focus groups and interviews informed by the RE-AIM framework. Deductive and inductive coding was conducted by four data analysts. Themes were validated with community members.
RESULTS: Parent focus groups, student and staff interviews provided insight into the ROSSEY study implementation. We identified five main themes: (i) social and financial drivers of participation; (ii) personal beliefs and unique challenges to research participation; (iii) intervention reinforced knowledge and shifted behavior; (iv) the appeal of comic books and videos supported adoption; and (v) multimodal communication and partnerships enhanced implementation.
CONCLUSIONS: The risk communication intervention was deemed culturally appropriate, reinforced previous knowledge, and encouraged adoption of preventive behaviors. The partnership with the school district and collaboration with the district's COVID-19 testing program ensured success of recruitment, study implementation, and adoption of preventive behaviors.

Analysis of antibody markers as immune correlates of risk of severe COVID-19 in the PREVENT-19 efficacy trial of the NVX-CoV2373 recombinant protein vaccine.
Clinical infectious diseases : an official publication of the Infectious Diseases Society of America [Epub ahead of print].
BACKGROUND: We previously showed that ancestral-specific anti-Spike binding IgG concentration and 50% inhibitory dilution neutralizing antibody titer (nAb-ID50) measured at 2 weeks post-dose 2 (∼peak) were inverse correlates of risk (CoRs) of COVID-19 over 2 months post ∼peak in the PREVENT-19 trial of the NVX-CoV2373 vaccine; there were not sufficient data to assess CoRs of severe COVID-19.
METHODS: Here we assessed, in the same vaccinated cohort, Delta- and ancestral-specific Spike IgG and nAb-ID50 at ∼peak and over time as CoRs of severe COVID-19 and of Delta COVID-19 over 3.5-10 months post ∼peak (287 breakthrough Delta cases, including 8 severe; 446 non-cases).
RESULTS: ∼Peak antibody levels were much higher for non-cases vs. severe cases (all inferred Delta), with nAb-ID50 Delta geometric mean 209.5 arbitrary units (AU)/mL (95% CI: 176.1, 249.1) vs. 9.6 AU/mL (95% CI: 2.4, 38.6), respectively. Frequency of detectable nAb-ID50 titer was 98.3% (97.2, 99.0) for non-cases vs. 62.5% (22.3, 93.9) for severe cases. All markers were inverse CoRs of severe COVID-19, with a ∼peak hazard ratio (HR) of 0.13 (95% CI: 0.03, 0.57) per 10-fold nAb-ID50 Delta increase. Severe COVID-19 risk through 305 days post-Day 35 was 0.0338 (0.0043, 0.206) at the nAb-ID50 Delta 2.5th percentile (8.4 AU/ml), and 0.002 (0.0000, 0.0108) and 0.0002 (0.0000, 0.0035) at the 50th and 95th percentiles (210, 2522 AU/ml).
CONCLUSIONS: Post-vaccination NVX-CoV2373 antibody levels are stronger predictors of severe COVID-19 than any-severity Delta COVID-19. Low antibody responses indicate vulnerability to severe COVID-19.

Who Is Eligible for Chimeric Antigen Receptor T Cell Therapy? Expert Perspectives on Overcoming Referral Barriers.
Transplantation and cellular therapy, 32(3):277-287.
CD19-directed chimeric antigen receptor T-cell (CAR-T) therapies, including lisocabtagene maraleucel, axicabtagene ciloleucel, and tisagenlecleucel, have revolutionized the treatment landscape for patients with hematologic malignancies. However, identification and referral of patients who could benefit from treatment remains a significant challenge, Here, we report expert recommendations for CAR-T therapy referral gathered from 10 experts in oncology, hematology, cardiology, and infectious diseases from a roundtable meeting and/or subsequent reviews between November 13, 2024, and June 9, 2025. We considered the following potential factors: age, performance status, disease status, cardiovascular function, pulmonary function, renal function, hepatic function, infections, and psychological health. Based on existing evidence, we agreed that none of the factors discussed should preclude patients from receiving referrals/further evaluation for CAR-T therapy, particularly with current advances in supportive care and integration of services from other specialties. Timely referral should be made by the patient's primary oncologist to specialists as early as the disease is deemed relapsed or refractory, preferably before the starting the subsequent line of therapy to allow better access to care and improve treatment outcomes. Before CAR-T therapy, holding therapy (before leukapheresis) and/or bridging therapy (after leukapheresis) may be given to patients with high-volume disease, in consultation with CAR-T therapy specialists. Based on the safety profile of CAR-T therapies, experts recommended flexible monitoring and transfer of care back to primary/community oncology physicians, starting from 2 weeks after infusion to improve access to this potentially curative therapy. Adaptations to clinical practice based on the most recent regulations, policy requirements, and institutional guidelines should be made as needed. In summary, a panel of 10 experts provided recommendations for timely patient referral for CAR-T therapy on the occurrence of relapsed or refractory disease and before the initiation of subsequent lines of therapy to improve care access and treatment outcomes. Experts noted that with close collaboration between CAR-T therapy specialists and other medical disciplines, CAR-T therapy remains a feasible option for most patients despite their comorbidities. © 2025 American Society for Transplantation and Cellular Therapy.

The timing of macronutrient and major food group intake and associations with mortality among United States adults, 1999‒March 2020: a serial cross-sectional study.
The American journal of clinical nutrition, 123(1):101097.
BACKGROUND: Eating timing has been increasingly linked to health, yet national trends in macronutrient/food group timing and their health implications remain unclear.
OBJECTIVES: To characterize trends in the timing of energy, macronutrient, and food group intake among United States adults and examine their associations with mortality.
METHODS: In this serial cross-sectional study of adults aged ≥20 y with ≥1 valid 24-h dietary recall (National Health and Nutrition Examination Survey, 1999‒March 2020), we examined secular trends in timing of energy, macronutrients, and major food group intake. Associations with mortality (through December 2019) were examined using Cox models.
RESULTS: Among 50,264 adults, evening (18:00-22:00) accounted for the highest daily energy intake (weighted mean proportions across years, 31.9%‒33.3%), followed by noon (10:00-14:00, 24.7%‒26.8%), afternoon (14:00-18:00, 19.9%‒21.8%), morning (06:00-10:00, 13.5%‒14.9%), and overnight (22:00-06:00, 5.6%‒6.5%); midnight (22:00-02:00) eating occurred in 23.4%‒28.0% of the population. Macronutrient and food groups followed similar patterns, except whole grain (peaked in the morning) and fruit, egg, and dairy intake (more evenly distributed). Over the years, noon and midnight energy intake proportions declined, whereas the afternoon proportion increased; secular trends varied by macronutrients/food groups. Fasting started at 20:34-20:51 and ended at 08:41-08:51; intake midpoint was 14:37-14:48; intake duration was 11.9‒12.2 h. Male, non-Hispanic Black, and socioeconomically disadvantaged groups had greater midnight intake proportions and later intake midpoints. Reallocating 5% of daily energy to midnight was associated with higher cardiovascular mortality (hazard ratio: 1.09; 95% confidence interval: 1.02,1.17), driven by carbohydrates; reallocating 5% to predawn (02:00-06:00) was associated with higher cancer mortality (hazard ratio: 1.22; 95% confidence interval: 1.05, 1.41), driven by proteins. Each 1-h delay in fasting and intake midpoint was associated with an 8%‒9% higher cardiovascular mortality.
CONCLUSIONS: Overnight intake and delayed eating timing are prevalent among United States adults, especially between socioeconomically disadvantaged groups, and were associated with higher mortality, particularly for specific macronutrients/foods, supporting eating timing recommendations integrating food composition.

Installation of dominant-negative mutations in FAS and TGFβR2 via base editing in primary T cells.
Molecular therapy. Oncology, 33(4):201063.
Adoptive cell transfer (ACT) of engineered T cells is effective against B cell malignancies but has faltered against solid tumors due to the immunosuppressive tumor microenvironment (TME). FAS ligand (FASL) and transforming growth factor β (TGF-β) are key mediators of T cell dysfunction in the TME and overexpressing dominant negative (dn) forms of their receptors in T cells increases anti-tumor efficacy in solid tumor models. However, an approach that directly targets the endogenous genes would be more amenable to multiplex editing and reduce competition with WT alleles. Here, we employ base editing (BE) in primary human T cells to install naturally occurring dominant negative FAS and TGFβR2 mutations. In vitro survival and proliferation assays demonstrate that BE T cells are resistant to pro-apoptotic and anti-proliferative effects of FAS and TGF-β signaling. Chimeric antigen receptor (CAR)-T cells with BE-installed dn TGFβR2 or dn FAS exhibit improvements in cytotoxicity, while dn TGFβR2 CAR T demonstrate increased persistence and reduced expression of phenotypic markers of exhaustion compared to controls. Moreover, BE-engineered dn CAR T outperform lentiviral-engineered cDNA over expression counterparts in several functional assays. Considering the efficiency of BE and its amenability for multiplex editing, our approach lends itself to engineering strategies necessary to overcome T cell dysfunction in solid tumors.

Transcriptional rewiring by enhancer methylation in CBFA2T3-GLIS2-driven pediatric acute megakaryoblastic leukemia.
Genes & diseases, 13(1):101843.
Resistance to chemotherapy and subsequent relapse remain the primary challenge in pediatric acute myeloid leukemia (pAML), particularly in CBFA2T3-GLIS2 (C/G) fusion-positive acute megakaryoblastic leukemia. Here we demonstrate that the C/G fusion drives extensive DNA methylation changes and oncogenic enhancer activation at cis-regulatory elements (CREs), reshaping gene expression. This multi-omics analysis reveals a distinct hypermethylation pattern at promoters of up-regulated genes in C/G[+] pAML across patient samples (n = 24) and representative cell lines, notably enriched in adhesion-related, TGFβ, or Wnt signaling pathways. Hypermethylated regions adjacent to transcription start sites (TSS) maintain open chromatin with H3K27ac enrichment, supporting a mechanism of de novo chromatin looping and active transcription in a non-canonical manner. Additionally, C/G fusion binding near the DNA methyltransferase 3B (DNMT3B) promoter correlates with elevated DNMT3B expression, implicating its role in aberrant DNA methylation changes at CREs. This study elucidates the epigenetic mechanisms driving C/G[+] pAML, showing how the fusion reshapes chromatin and DNA methylation landscapes by impacting the expression (and likely activity) of epigenetic modifiers like DNMT3B. Functionally, DNMT3B inhibition enhances apoptotic sensitivity to BCL2 blockade, indicating that targeting DNMT3B may overcome apoptotic resistance in C/G[+] leukemic cells and offer a therapeutic strategy for this high-risk subtype.

Antiretroviral Therapy Intensification With Dolutegravir and/or Maraviroc Did Not Affect HIV-1 Cell-Associated DNA, RNA, and 2--LTR Circles Over 12 Weeks.
Open forum infectious diseases, 12(10):ofaf594.
BACKGROUND: Neurocognitive impairment (NCI) among people living with human immunodeficiency virus (HIV; PWH) on antiretroviral therapy (ART) may result from residual viral replication. The A5324 trial found that ART intensification with dolutegravir (DTG) with or without maraviroc (MVC) did not affect NCI in PWH. We evaluated the impact of ART intensification on peripheral virological measures during the first 12 weeks of intensification.
METHODS: The A5324 study was a randomized, double-blind, placebo (PBO)-controlled, 96-week trial of ART intensification with either dual PBO, DTG + PBO, or DTG + MVC in PWH with NCI on ART who were naive to integrase strand transfer inhibitors and MVC. At baseline and weeks 2, 4, and 12, HIV-1 RNA was measured in plasma with a low-copy assay, while HIV-1 cell-associated DNA (caDNA), cell-associated unspliced RNA (caRNA), and cell-associated 2-long terminal repeat circles (ca2LTR) were quantified from peripheral blood mononuclear cells using droplet digital polymerase chain reaction.
RESULTS: Of the 171 participants, 59 were randomized to dual PBO, 57 to DTG + PBO, and 55 to DTG + MVC. Changes in caDNA and caRNA and detection of plasma RNA did not differ between treatment arms over 12 weeks (P > 0.05). Detection of ca2LTR was less frequent at weeks 2-4 in the DTG + MVC arm (40.4%) than in the dual-PBO (70.7%; P =0 .02) and DTG + PBO (68.4%; P = 0.03) arms. However, this difference diminished by week 12, and baseline ca2LTR detection in the DTG + MVC arm was lower than in the other groups.
CONCLUSIONS: DTG intensification had no effect on peripheral markers of HIV-1 persistence. DTG + MVC intensification reduced ca2LTR detection at weeks 2-4, though this effect did not persist through week 12. These findings indicate the minimal impact of intensification on the HIV-1 peripheral reservoir, consistent with prior studies.

Meeting Summary for Keystone Symposia on HIV Cure: Antiretroviral Therapy (ART)-Free Control of HIV Infection in Durban, South Africa, 2025.
Pathogens & immunity, 10(2):196-229.
Antiretroviral therapy (ART) can effectively control human immunodeficiency virus (HIV) replication; however, lifelong treatment is required due to viral reservoirs, which fuel viral rebound. This necessitates curative interventions that can achieve either eradication of the reservoir or durable remission off ART. Advances in technology have fostered development of multi-omic techniques encompassing molecular tools, proteomic analyses, imaging, and artificial intelligence (AI)-driven data analysis to understand HIV reservoir biology and persistence. These have informed the investigation of therapeutic interventions such as broadly neutralizing antibodies, latency reversal, immune cell augmentation, antivirals, and gene therapy. From April 7-10, 2025, experts in the field convened at the Keystone Symposia conference, HIV Cure: Antiretroviral Therapy (ART)-Free Control of HIV Infection in Durban, South Africa, to discuss novel strategies for eradication and/or durable ART-free control of HIV.

Cell-of-Origin Subtype Predicts Response to Polatuzumab Vedotin in Large B-cell Lymphoma.
Clinical cancer research : an official journal of the American Association for Cancer Research, 32(1):159-168.
PURPOSE: Polatuzumab vedotin (polatuzumab) was approved for up-front treatment of diffuse large B-cell lymphoma in combination with chemoimmunotherapy (Pola-R-CHP) based on the POLARIX trial. However, when stratified by cell of origin (COO), polatuzumab seems to have greater efficacy in activated B-cell than germinal center B-cell (GCB) subtype disease. Most studies of polatuzumab used RNA expression to assess COO, whereas in routine clinical practice, the immunohistochemistry-based Hans algorithm is used.
EXPERIMENTAL DESIGN: To assess the impact of COO by immunohistochemistry on polatuzumab efficacy, we conducted a multicenter real-world study of adults with large B-cell lymphoma (LBCL) receiving polatuzumab from 2015 to 2024, split by receipt of polatuzumab in first-line versus relapsed/refractory settings. The primary endpoint was overall response rate (ORR) to polatuzumab-based treatment in GCB versus non-GCB relapsed/refractory LBCL.
RESULTS: Of 740 patients, 305 received polatuzumab in the first-line setting and 435 in the relapsed/refractory setting. In the relapsed/refractory cohort, the ORR in non-GCB versus GCB LBCL was 59.7% versus 36.3% [OR, 2.6; 95% confidence interval (CI), 1.77-3.84; P < 0.0001], with a complete response rate of 35.7% versus 17.7% (OR, 2.6; 95% CI, 1.66-4.02; P < 0.0001). Progression-free survival was longer for patients with non-GCB versus GCB COO (HR, 0.64; 95% CI, 0.5-0.83; P = 0.0006). In the first-line cohort, ORR, complete response rate, and progression-free survival were similar in non-GCB versus GCB LBCL, as hypothesized based on outcomes in the Pola-R-CHP arm of POLARIX, suggesting that the addition of polatuzumab overcomes the adverse risk of non-GCB COO in patients receiving R-CHOP.
CONCLUSIONS: Based on these data, COO classification by the Hans algorithm is a strong predictor of polatuzumab efficacy in LBCL, informing real-world treatment decisions.

abstract = {PURPOSE: Polatuzumab vedotin (polatuzumab) was approved for up-front treatment of diffuse large B-cell lymphoma in combination with chemoimmunotherapy (Pola-R-CHP) based on the POLARIX trial. However, when stratified by cell of origin (COO), polatuzumab seems to have greater efficacy in activated B-cell than germinal center B-cell (GCB) subtype disease. Most studies of polatuzumab used RNA expression to assess COO, whereas in routine clinical practice, the immunohistochemistry-based Hans algorithm is used.
EXPERIMENTAL DESIGN: To assess the impact of COO by immunohistochemistry on polatuzumab efficacy, we conducted a multicenter real-world study of adults with large B-cell lymphoma (LBCL) receiving polatuzumab from 2015 to 2024, split by receipt of polatuzumab in first-line versus relapsed/refractory settings. The primary endpoint was overall response rate (ORR) to polatuzumab-based treatment in GCB versus non-GCB relapsed/refractory LBCL.
RESULTS: Of 740 patients, 305 received polatuzumab in the first-line setting and 435 in the relapsed/refractory setting. In the relapsed/refractory cohort, the ORR in non-GCB versus GCB LBCL was 59.7% versus 36.3% [OR, 2.6; 95% confidence interval (CI), 1.77-3.84; P < 0.0001], with a complete response rate of 35.7% versus 17.7% (OR, 2.6; 95% CI, 1.66-4.02; P < 0.0001). Progression-free survival was longer for patients with non-GCB versus GCB COO (HR, 0.64; 95% CI, 0.5-0.83; P = 0.0006). In the first-line cohort, ORR, complete response rate, and progression-free survival were similar in non-GCB versus GCB LBCL, as hypothesized based on outcomes in the Pola-R-CHP arm of POLARIX, suggesting that the addition of polatuzumab overcomes the adverse risk of non-GCB COO in patients receiving R-CHOP.

Application of implementation science methods and theories for cancer control planning in low-income and middle-income countries: a scoping review.
BMJ open, 15(10):e108755.
INTRODUCTION: Implementation science (IS) is increasingly recognised as vital in cancer control planning and integrating evidence-based interventions across the cancer care continuum. Contextual differences often cause variability in delivering optimised healthcare, which IS approaches could mitigate. While IS improves planning effectiveness, many programme and policy planners remain unaware of its benefits. To address this, we examined IS theories applied to national cancer control plans (NCCPs)/strategies across five domains: stakeholder engagement, situational analysis, capacity assessment, economic evaluation and impact assessment.
METHODS: We conducted a scoping review using the Arksey and O'Malley framework to analyse NCCPs and strategies from 16 and 17 countries belonging to low and medium categories of Human Development Index (HDI), focusing on resource-constrained settings. We identified plans through the International Cancer Control Partnership portal, categorised them by WHO region and included only those available in English or French. We extracted data into a Microsoft Excel database and performed thematic analysis across five IS domains. Multiple IS experts, selected purposively based on their familiarity with resource-constrained settings, validated the findings, assessed policy relevance and helped develop a pathway for integrating IS into national cancer control planning. They reviewed structured questions in advance and provided feedback on analyses, practical utility, dissemination and simplifying IS application, which was used to refine the pathway and reach consensus.
RESULTS: While many NCCPs incorporated key IS elements such as stakeholder engagement, situational analysis and impact measurement, these often needed to be more explicit and consistently applied. None of the plans assessed health system capacity to determine readiness for implementing new interventions. Although most plans described stakeholder engagement, it was typically unstructured and incomplete. Four low HDI and nine medium HDI countries included costed plans, generally using an activity-based approach. All plans included impact measures (eg, key performance indicators), but five lacked mechanisms for engaging stakeholders or responsible entities to achieve the targets. These findings informed a proposed pathway to integrate IS principles into cancer control planning.
CONCLUSION: Integrating IS into national cancer control planning offers a structured framework for achieving equitable and feasible cancer control policies, particularly in resource-constrained settings, by enabling realistic goal setting and benchmarking against regional and global standards.

Heavy-chain immunoglobulin locus editing in rhesus macaque B cells to confer antibody production.
Molecular therapy. Methods & clinical development, 33(4):101598.
Antibody-based immunotherapies are promising; however, their application remains limited to acute diseases due to rapid clearance of antibodies in vivo. Some chronic conditions could benefit from sustained therapeutic antibody expression. One such instance is human immunodeficiency virus type 1 (HIV-1), where the efficiency of broadly neutralizing antibodies by passive immunization has been limited in clinical trials. B cell editing to enable sustained production of an antibody of interest in vivo could address this issue. However, the long-term potential of this approach and feasibility to perform editing in B cells from people living with HIV remain to be determined. We investigated editing of rhesus macaque B cells from healthy or simian/human immunodeficiency virus (SHIV)-infected animals to model this approach. An antibody-encoding cassette was inserted in the immunoglobulin locus by CRIPSR-Cas9-mediated ex vivo B cell editing. Similar indel efficiencies were achieved in B cells from both uninfected and infected animals, and expression of the antibody of interest was detected in up to 10% of uninfected B cells. This study paves the way for future in vivo work to assess the long-term potential of this approach and its impact on B cell development and function in an immunocompetent in vivo nonhuman primate model of HIV persistence and cure.

Psychometric properties of the NIH Toolbox Cognition Battery composites in older adults at risk for Alzheimer's disease and related dementias: A systematic review.
Alzheimer's & dementia : the journal of the Alzheimer's Association, 21(10):e70673.
This systematic review evaluated the psychometric performance of the National Institutes of Health's Toolbox Cognition Battery (NIHTB-CB) composite scores in older adults with and without Alzheimer's disease and related dementias (ADRD). A systematic literature search was conducted using MEDLINE, Embase, PsycINFO, and CINHAL databases. The evidence quality of NIHTB-CB measurement properties was assessed using integrated Consensus-based Standards for the Selection of Health Measurement Instrument (COSMIN) methodology and the Interpretation/Use Argument framework. Fourteen studies met inclusion criteria for this review of the NIHTB-CB. Evidence supporting the scoring, generalization, and extrapolation inferences of the Total, Crystallized, and Fluid composite scores in older adults ranged from developing through exemplary ratings. Findings indicate additional research is warranted on the NIHTB-CB in older adult and ADRD populations. The present study highlights the importance of continued use and research of the NIHTB-CB in diverse, older populations who are at risk for ADRD. HIGHLIGHTS: Limited research focuses on the National Institutes of Health's Toolbox Cognition Battery (NIHTB-CB) composites in older adults. The general psychometric robustness of the NIHTB-CB has been es. The Crystallized composite shows proficient psychometric evidence. The psychometric evidence of Fluid composite is developing due to limited data.

Dynamic Monitoring of Recurrent Ovarian Cancer Using Serial ctDNA: A Real-World Case Series.
Current oncology (Toronto, Ont.), 32(10):.
Recurrent ovarian cancer (OC) is challenging to detect early using current methods like CA-125 and imaging. Circulating tumor DNA (ctDNA) may improve disease monitoring. Here, we assess the real-world clinical utility of serial ctDNA analyses in patients with recurrent OC. We analyzed serial plasma samples (N = 23) from six patients with recurrent OC using a tumor-informed next-generation sequencing assay targeting 68 cancer-related genes developed at the University of Washington. ctDNA variant allele frequencies (VAFs) were correlated with CA-125 levels, radiographic findings, and clinical outcomes. ctDNA levels generally reflected clinical status, accurately mirroring disease progression and therapeutic response. In one patient, rising ctDNA preceded clinical recurrence by four months, despite normal CA-125 and imaging, highlighting its potential advantage. Conversely, some patients exhibited clinical progression with undetectable ctDNA, indicating limitations in assay sensitivity, biological factors, or metastatic sites (e.g., brain metastases). ctDNA and CA-125 showed complementary value in most cases, suggesting potential combined use in clinical monitoring. Our findings demonstrate that ctDNA is a promising biomarker to complement existing monitoring approaches for recurrent OC. In some cases, capable of predicting relapse and treatment response ahead of current clinical indicators. However, identified discordances underscore technical and biological challenges that warrant further investigation. Larger prospective studies are necessary to refine ctDNA's clinical utility and integration into personalized OC care.

Efficacy of sacituzumab govitecan after enfortumab vedotin in advanced urothelial carcinoma: Analysis of the UNITE study.
Urologic oncology, 44(1):65.e1-65.e11.
BACKGROUND: Sacituzumab govitecan (SG) is an antibody-drug conjugate used for advanced urothelial carcinoma (aUC) refractory to platinum-based chemotherapy and immune checkpoint inhibitors (ICI). Real-world data are needed to better define SG outcomes, particularly following treatment with enfortumab vedotin (EV). In this analysis, we aim to evaluate efficacy of SG after EV and assess putative biomarkers associated with outcomes.
METHODS: In the UNITE retrospective study, we identified patients who received ≥1 SG cycle after therapy with EV. Observed response rate (ORR) was assessed in evaluable patients and correlated with baseline clinical characteristics and biomarkers. ORRs were compared using logistic regression, while progression free survival (PFS) and overall survival (OS) from SG start were estimated via Kaplan-Meier and Cox proportional hazard (PH) model. Biomarkers of response were evaluated in multivariate Cox PH models after accounting for relevant clinical variables.
RESULTS: Among 107 patients treated with SG after EV, 97 (91%) had NGS data. Median age was 69 years, 73% were male, 33% had ≥4 prior lines of therapy, and 42% received G-CSF. ORR was 18% (95% CI: 10%-26%), median PFS 3.2 months, and median OS 6.0 months. In patients with disease control on EV, ORR was 22% compared to 8% in primary progressors on EV. No significant associations were found between molecular biomarkers and SG outcomes in the multivariate analysis.
CONCLUSION: SG showed modest activity after EV in heavily pretreated patients with aUC. ORR with SG after EV was lower than reported in phase 2 and phase 3 clinical trials for SG in the postplatinum/ICI setting.

Exploration of the roles of HLAs when predicting infection status by T cell receptors.
Scientific reports, 15(1):37638.
T cells are critical components of the human immune system. When a cell is infected by a virus, it presents viral peptides on its surface using human leukocyte antigen (HLA) proteins. These peptide-HLA complexes are recognized by T cells through interactions with T cell receptors (TCRs). A human blood sample can contain millions of unique TCRs, which is a sample from the individual's TCR repertoire. TCR repertoire-wide association studies (TReWAS) aim to evaluate the associations between individual TCRs and disease or exposure status. Previous studies have shown that TCRs associated with viral infections can be identified using TReWAS, and these TCRs can be used to predict current or past infection with high accuracy. Many TCRs are strongly associated with specific HLA alleles, suggesting that the incorporation of HLA information could improve the precision of TReWAS analyses and predictions based on TCRs. In this study, we evaluated TCR-based predictions while conditioning on individual HLA alleles or their k-nearest neighbors. We observed improved prediction accuracy for some HLA alleles. Furthermore, these HLA-specific predictions provide insight into the role of specific HLAs in coordinating immune response to immunogenic antigens, demonstrating the benefit of HLA-aware analysis of TCR data.

abstract = {T cells are critical components of the human immune system. When a cell is infected by a virus, it presents viral peptides on its surface using human leukocyte antigen (HLA) proteins. These peptide-HLA complexes are recognized by T cells through interactions with T cell receptors (TCRs). A human blood sample can contain millions of unique TCRs, which is a sample from the individual's TCR repertoire. TCR repertoire-wide association studies (TReWAS) aim to evaluate the associations between individual TCRs and disease or exposure status. Previous studies have shown that TCRs associated with viral infections can be identified using TReWAS, and these TCRs can be used to predict current or past infection with high accuracy. Many TCRs are strongly associated with specific HLA alleles, suggesting that the incorporation of HLA information could improve the precision of TReWAS analyses and predictions based on TCRs. In this study, we evaluated TCR-based predictions while conditioning on individual HLA alleles or their k-nearest neighbors. We observed improved prediction accuracy for some HLA alleles. Furthermore, these HLA-specific predictions provide insight into the role of specific HLAs in coordinating immune response to immunogenic antigens, demonstrating the benefit of HLA-aware analysis of TCR data.},

Multiomics Investigation of Exhausted T Cells in Glioblastoma Tumor Microenvironment: CCL5 as a Prognostic and Therapeutic Target.
International journal of molecular sciences, 26(20):.
Glioblastoma multiforme (GBM) is a common malignancy with poor prognosis, and exhausted T (TEX) cells, a subset of T cells characterized by progressive loss of effector functions, play a critical role in its progression. This study aimed to investigate the impact of TEX-related genes on immune function, prognosis, and drug sensitivity in GBM through multiomics analysis. Initially, we identified a novel set of TEX-related genes specific to GBM and screened hub genes (CCL5, IL18, CXCR6, FCER1G, TNFSF13B) using conventional statistical methods combined with machine learning. A prognostic risk model was subsequently constructed based on TCGA data and validated in the CGGA cohort. Single-cell and pharmacogenomic analyses revealed significant differences in tumor microenvironment composition and drug sensitivity between risk groups. Notably, Palbociclib emerged as a potential therapeutic agent targeting the novel discovered biomarker CCL5. RT-qPCR results showed that T cells with low CCL5 expression exhibited reduced expression of immune checkpoint-related genes (PD1, TIM3, LAG3) and increased expression of CD28, suggesting enhanced immune function. In conclusion, our findings highlight five hub genes as prognostic markers that could stratify GBM patients with different immune landscapes and levels of drug sensitivity. Furthermore, experimental results suggest that low CCL5 expression could alleviate T cell exhaustion and represent a promising therapeutic target, offering new strategies for improving GBM prognosis.

Bedside manufacturing of engineered stem cells using gene therapy foam.
Molecular therapy. Methods & clinical development, 33(4):101612.
Hematopoietic stem cell (HSC) gene therapies hold immense potential for treating a growing list of genetic disorders, but the field has reached an inflection point where novel technologies are needed to overcome significant challenges, including high costs, unequal access, and prolonged disruption of daily life. Here, we describe a bedside cell manufacturing strategy in which HSCs are genetically targeted within gene therapy foam that is mixed with freshly isolated bone marrow aspirate concentrate and then directly injected back into the marrow. We demonstrate that highly efficient genetic reprogramming of CD34+ HSCs can be accomplished within methylcellulose-based foam, using low vector doses that are inefficient with conventional liquid-based approaches. In an ex vivo model of perfused bone marrow, we show that foam retains vector at the injection site and locally boosts gene transfer into embedded CD34+ progenitor cells while minimizing off-target events. We also establish that this foam technology is compatible with freshly harvested human bone marrow aspirate. Once implemented in the clinic, this new method, which can be performed in an outpatient setting of any regional hospital, could improve the effectiveness of stem cell-based gene therapies, while concomitantly lowering costs to make these treatments accessible to all who need them.

Optimizing Palliative Cancer Surgery Trial Completion: Lessons Learned From Qualitative Content Analysis of S1316 - Comparative Effectiveness Trial for Malignant Bowel Obstruction.
The American journal of hospice & palliative care [Epub ahead of print].
BackgroundMalignant bowel obstruction (MBO) is a complex clinical entity and there remains a relative lack of high-quality comparative trials on surgical management, in part due to a heterogeneous patient population and different treatment modalities which contribute to challenges in trial design and completion. SWOG S1316 is the only prospective randomized trial evaluating surgical vs non-surgical management of MBO and involved a trial framework in which patients were recruited for a randomization pathway as well as a patient choice pathway. Importantly, successful completion of S1316 required numerous amendment modifications to the trial during its course. We aimed to highlight aspects of S1316 trial design, execution, and modification that potentially contributed to trial completion.MethodsIterative qualitative content analysis of trial modification amendments through the course of the trial from 2015 to 2020.Results133 unique amendments were made to S1316 from 2015 to 2020. We found four dominant domains for the amendments: Accrual Barriers, Study Design Changes, Data Collection Issues, and Clarifications. Accrual amendments were essential to completing the trial and included increasing participating sites from six to 30 (including international sites) and the inclusion of Spanish-speaking participants (11% of final study population).ConclusionsContent analysis of S1316 trial amendments highlighted that Accrual amendments were important in trial completion. Future investigators may benefit from better anticipating trial modifications as they design their studies. It is likely that rapid initiation of trial amendments can lead to improved accrual and study completion.

An integrated analysis of three medulloblastoma clinical trials refines risk-stratification approaches for reducing toxicity and improving survival.
Neuro-oncology, 28(1):268-281.
BACKGROUND: The identification of clinical and molecular heterogeneity in medulloblastoma has produced risk-stratified therapy, but establishing the most effective yet least toxic regimens has remained elusive owing to numerous treatment options. To improve risk-stratification, we performed an integrated analysis from three clinical trials.
METHODS: Medulloblastoma patients from ACNS0331/NCT00085735, ACNS0332/NCT00392327, and SJMB03/NCT00085202 were included if they had methylation profiling. Molecular groups [WNT, SHH, Group 3 (G3), and Group 4 (G4)], subgroups, and copy number variations were procured from methylation profiles and mutations from next-generation sequencing. Data was assembled into an interactive portal to capture patient characteristics. Cross-trial comparisons, univariable, and multivariable analyses were conducted and used to derive a risk-stratification schema.
RESULTS: Eight hundred ninety-eight patients (WNT = 131, SHH = 151, G3 = 220, G4 = 396) were included. Progression-free-survival (PFS) distributions among analogous cross-trial cohorts were not different, demonstrating no survival advantage of any one therapy over another. The addition of carboplatin to high-dose craniospinal irradiation (HDCSI) containing regimen was selectively superior in PFS in G3/G4 subgroup 3 (P = 0.048) and G3/G4 subgroup 2 (P = 0.035) to HDCSI regimens without carboplatin. Nine actionable risk-stratified groups were identified consisting of 2 WNT groups (low, high-risk), 3 SHH groups (low-, average-, very-high-risk), and 4 G3/G4 groups (low-, average-, high-, and very-high-risk).
CONCLUSIONS: Our integrated cross-trial analysis suggests toxicity can be reduced by eliminating disproportionate differences in therapy in favor of a more uniform treatment backbone. Moreover, we propose and model a risk-classification system that identifies the most appropriate cohorts on which to trial significant dose reductions in craniospinal irradiation or select treatment intensifications.

Integrated transcriptomic landscape of medulloblastoma and ependymoma reveals novel tumor subtype-specific biology.
Neuro-oncology, 28(2):505-519.
BACKGROUND: Medulloblastoma and ependymoma are common pediatric central nervous system tumors with significant molecular and clinical heterogeneity. While molecular subgrouping has enabled classification into molecular subtypes, the extent of heterogeneity within these subgroups remains poorly defined.
METHODS: We collected bulk RNA sequencing data from 888 medulloblastoma and 370 ependymoma tumors to establish a comprehensive reference landscape. After rigorous batch effect correction, normalization, and dimensionality reduction, we generated a unified landscape to explore gene expression, signaling pathways, RNA fusions, and copy number variations.
RESULTS: Our transcriptional analysis revealed distinct clustering patterns, including two primary ependymoma compartments, EPN-E1 and EPN-E2, each with specific RNA fusions and molecular signatures. In medulloblastoma, we observed precise stratification of Group 3/4 tumors by subtype and in Sonic Hedgehog (SHH) tumors by patient age. We also identified subtype-specific pathways and gene fusions, enriched in each group.
CONCLUSIONS: This transcriptomic landscape serves as a resource for biomarker discovery, diagnostic refinement, and prediction of tumor biology and outcome. By enabling projection of new patients' bulk RNA-seq data onto the reference map using nearest neighbor analysis, the framework supports accurate subtype classification. The landscape is publicly available via Oncoscape, an interactive platform for global exploration and application.

Targeting the Androgen Receptor Pathway in Prostate Cancer: A PROTrACted Struggle.
Clinical cancer research : an official journal of the American Association for Cancer Research, 32(1):13-15.
The androgen receptor (AR) is the most important therapeutic target for metastatic prostate cancer. Though clinical responses to AR inhibition are nearly universal, so is progression, usually accompanied by reactivation of AR signaling. A new small-molecule dual AR degrader/inhibitor shows promise in overcoming resistance and improving clinical outcomes. See related article by Nayak et al., p. 224.

Antibiotic risk score for acute graft-versus-host disease.
Blood advances, 10(3):555-561.
Certain antibiotic exposures have been associated with increased rates of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic cell transplant (alloHCT). Using data from 2023 alloHCTs performed at our center (2010-2021), we recently developed an antibiotic risk score based on antibacterial antibiotic exposure between days -7 and +30 of alloHCT. The objective was to estimate the added risk for aGVHD due to exposures to antibiotics in the early peritransplant period. Here, we validated the score in an independent, more recent cohort. Data from 297 recipients of alloHCT (2022-2023) including 8382 antibiotic use records (9 antibiotic classes) were analyzed. Median (range) age was 61 (19-78) years, and 175 (59%) patients were male. Higher scores predicted a greater added antibiotic-related risk for grade 3 to 4 (severe) aGVHD, with the upper 25% score quantile identifying a distinctly high-risk subset of patients (hazard ratio for the upper 25% risk quantile was 2.37 compared with the lower 75%; 95% confidence interval, 1.21-4.63; P = .01). A similar, though less strong, pattern was observed for grade 2 to 4 aGVHD. A free online antibiotic risk calculator was developed, identifying antibiotic exposures associated with higher added risk for severe aGVHD. In addition to its potential future use to identify patients who were at higher risk for aGVHD due to antibiotic exposures, the antibiotic-based risk score provided here can be included as a single continuous covariate in multivariable analysis of future GVHD prophylaxis trials.

Higher scores predicted a greater added antibiotic-related risk for grade 3 to 4 (severe) aGVHD, with the upper 25% score quantile identifying a distinctly high-risk subset of patients (hazard ratio for the upper 25% risk quantile was 2.37 compared with the lower 75%; 95% confidence interval, 1.21-4.63; P = .01). A similar, though less strong, pattern was observed for grade 2 to 4 aGVHD. A free online antibiotic risk calculator was developed, identifying antibiotic exposures associated with higher added risk for severe aGVHD. In addition to its potential future use to identify patients who were at higher risk for aGVHD due to antibiotic exposures, the antibiotic-based risk score provided here can be included as a single continuous covariate in multivariable analysis of future GVHD prophylaxis trials.},

Hemostatic Disorders Following Severe Acute Respiratory Syndrome Coronavirus 2 Infection, COVID-19 Vaccination, and Long-COVID Syndrome: Current Evidence and Controversies in Clinical Practice.
Clinics in laboratory medicine, 45(4):643-655.
The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has presented profound global health challenges. Beyond acute illness, a substantial proportion of individuals experience persistent symptoms including fatigue, brain fog, and post-exertional malaise, collectively known as Long-COVID. Among the complications associated with SARS-CoV-2 infection and vaccination, hemostatic disorders ranging from mild platelet dysfunction to severe thromboembolic events, and rare but serious coagulation-related adverse effects, such as vaccine-induced immune thrombotic thrombocytopenia, have emerged as a significant concern. Herein we provide an overview of current information and controversies surrounding hemostatic complications in SARS-CoV-2 infection and COVID-19 vaccination.

Recent Advances in Extended Half-Life Products, Nonfactor Replacement Therapies, and Gene Therpy for the Treatment of Hemophilia.
Clinics in laboratory medicine, 45(4):657-673.
Hemophilia, a rare X-linked hereditary bleeding disorder, is characterized by deficiency of coagulation factors. Symptoms range from spontaneous joint and muscle bleeds to life-threatening hemorrhage, for which patients require frequent infusion of coagulation factors, profoundly impacting their quality of life. Novel therapeutics and advances in gene therapy now offer patients long-term disease control and improved quality of life. Here, we focus on important developments in the use of extended half-life factor products, non-factor replacement therapies, and gene therapy. We also highlight the mechanism of action, clinical efficacy, and safety of these newer approaches.

Machine Learning and Artificial Intelligence-Based Clinical Decision Support for Modern Hematology.
Clinics in laboratory medicine, 45(4):691-705.
Hematology is one of the most data-rich areas of medicine and has consistently been at the forefront of technological innovation. With the increasing integration of machine learning (ML) into the diagnostic process, it is vital that both patient-facing and laboratory-facing members of the care team understand how these tools may interact with existing workflows and affect their work. We review the current landscape of ML research and clinical applications. We cover a wide variety of subdomains (eg, hematopathology, hemoglobinopathies, and coagulopathy) and explore both the success and limitations of corresponding research and deployments.

Association between ancestry and tumor somatic mutations in a large national cohort of women with breast cancer.
NPJ breast cancer, 11(1):117.
Somatic mutations and copy number alterations in breast tumors are important to determine prognosis, predict treatment response, and identify targets for therapy. We utilized somatic sequencing data of breast tumors from Foundation Medicine Inc. to evaluate the association between genetic ancestry and somatic mutations. We used germline variants to infer genetic ancestry with both principal components analysis and ADMIXTURE. Overall, we identified 91 ancestry-specific somatic differences across 58 unique genes, which included potentially targetable genes such as PIK3CA found in higher frequency in European ancestry, and EGFR found in higher frequency in East Asian ancestry. Pan-cancer analysis of East Asian ancestry and EGFR also found higher frequency in prostate, thyroid, and kidney cancers. African ancestry was associated with increased frequency of copy number alterations overall and decreased frequency of multiple genes on the PI3K-AKT pathway. Future research is warranted to elicit the genetic and environmental conditions that underly these findings.

Negative perceptions of the health system and racial inequities in PSA screening.
Prostate cancer and prostatic diseases [Epub ahead of print].
BACKGROUND: Black individuals in the U.S. experience significantly higher prostate cancer mortality and are more likely to be diagnosed at younger ages with aggressive disease. This disparity may be influenced by negative healthcare perceptions and racial discordance between patients and providers, impacting lower rates of prostate-specific antigen (PSA) screening. We hypothesized that these factors would be associated with reduced PSA screening uptake, particularly among Black men.
OBJECTIVES: This study aimed to examine the association between negative healthcare perceptions and PSA screening, assess whether this relationship differs by race, and evaluate the role of racial discordance in influencing screening behavior.
METHODS: We analyzed data from the 2018-2022 Medical Expenditure Panel Survey. The sample included 2373 men aged 45-70 who self-identified as non-Hispanic White or Black and had complete data on PSA screening, healthcare perceptions, and demographics. Negative healthcare perceptions were measured using a Health Perceptions Index (HePI), constructed from MEPS items (higher scores reflect more negative perceptions).
RESULTS: Higher HePI scores were significantly associated with lower PSA screening rates (p < 0.01). Interaction models indicated that Black men with higher HePI scores were disproportionately less likely to undergo screening. Racial discordance with providers was independently associated with reduced screening likelihood (~10.2 percentage points; p < 0.01). Models including interaction terms (age, race, and discordance) showed that older Black men with high HePI scores and discordant providers were least likely to be screened.
CONCLUSIONS: PSA screening disparities are shaped by negative healthcare perceptions and racial discordance, particularly among older Black men. Addressing these barriers through culturally tailored education, improved workforce diversity, and strengthened provider-patient relationships may help close screening gaps. These findings highlight the relevance of healthcare system perceptions in understanding screening disparities and may inform future strategies to identify at-risk individuals.

Surgical Volume and Outcomes of Intraoperative Transesophageal Echocardiography in Coronary Artery Bypass Graft.
JAMA network open, 8(10):e2540559.
IMPORTANCE: The routine use of intraoperative transesophageal echocardiography (TEE) during coronary artery bypass graft (CABG) surgery remains controversial. Its benefit across different patient populations is unclear.
OBJECTIVES: To identify patient subgroups with the greatest or least likelihood to benefit from intraoperative TEE during CABG, stratified by hospital surgical volume.
This 2-stage, matched retrospective cohort study applied target trial emulation methodologies to the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) to quantify the conditional treatment effect of intraoperative TEE among subpopulations undergoing isolated CABG at low, medium, and high surgical volume hospitals. The study cohort consisted of patients aged 18 years or older who underwent isolated CABG surgery between July 1, 2014, and June 30, 2022. Data analysis was conducted from August 8, 2023, to December 15, 2024.
EXPOSURE: Receipt of an intraoperative TEE during CABG surgery.
MAIN OUTCOMES AND MEASURES: The primary outcome was mortality within 30 days of surgery. Statistical analyses included multivariable logistic regression and multiple TEE vs without TEE matched comparisons stratified by surgical volume and patient subpopulations.
RESULTS: Of 1 266 055 patients who underwent isolated CABG, 963 976 (76.1%) were male, and the mean (SD) age was 65.7 (10.0) years. Among these patients, 61.8% received TEE and 39.0% did not receive TEE. Intraoperative TEE use (vs without TEE) was associated with a significant survival benefit among patients treated at hospitals with low surgical volume (2.47% vs 2.94%; odds ratio [OR], 0.83 [95% CI, 0.78-0.89], P < .001) and medium surgical volume (2.09% vs 2.34%; OR, 0.89 [95% CI, 0.85-0.93], P < .001) but not high surgical volume (1.72% vs 1.77%; OR, 0.97 [95% CI, 0.91-1.03], P = .48). Among patients who underwent isolated CABG at low and medium surgical volume hospitals, TEE provided the greatest survival benefit to subpopulations with greater than 50% (vs ≤50%) left-main coronary stenosis, 3 or more (vs <3) diseased coronaries, and (3) a preoperative inotropic requirement.
CONCLUSIONS AND RELEVANCE: In isolated CABG, intraoperative TEE was associated with survival benefit at low- and medium-volume hospitals, particularly in patients with complex coronary disease or hemodynamic instability, but not at high-volume hospitals. These results highlight persistent equipoise and the need for randomized evaluation.

Multiple polygenic score approach in colorectal cancer risk prediction.
Scientific reports, 15(1):38006.
Recent studies have demonstrated that for various diseases, incorporating polygenic risk scores (PRSs) for other traits and diseases into the PRS-based risk prediction model may improve predictive performance - known as Multiple Polygenic Score (MPS) approach. We aimed to examine whether the MPS approach improves colorectal cancer (CRC) risk prediction. We included 2,187 non-CRC PRSs from the polygenic Score (PGS) Catalog and used machine learning (ML) models to select the most predictive non-CRC PRSs, utilizing individual-level data from 31,257 CRC cases and 33,408 controls. An independent dataset from the Genetic Epidemiology Research in Adult Health and Aging (GERA) cohort (4,852 cases and 67,939 controls) was randomly split into subsets for model estimation and validation. The model combined MPS with two existing CRC-PRSs based on known loci and genome-wide genotyping. We then assessed model performance by calculating the area under the receiver operating curve (AUC) in the validation set and performed 1,000 bootstrapped iterations to evaluate AUC improvements. The ML model selected 337 non-CRC PRSs predictive of CRC risk. Adding MPS to the CRC-PRSs significantly improved AUC by 0.017 (95% CI: 0.011-0.022, p < 0.0001) when combined with known-loci CRC-PRS, 0.005 (95% CI: 0.002-0.007, p = 0.0005) with genome-wide CRC-PRS, and 0.004 (95% CI: 0.002-0.006, p = 0.0005) with both the known loci and genome-wide CRC-PRSs. These findings demonstrate MPS's potential to refine CRC risk prediction models and highlight opportunities for further advancements in risk prediction.

Human immunodeficiency virus and antiretroviral therapies exert distinct influences across diverse gut microbiomes.
Nature microbiology, 10(11):2720-2735.
Human immunodeficiency virus (HIV) infection alters gut microbiota composition and function, but the impact of geography and antiretroviral therapy remains unclear. Here we determined gut microbiome alterations linked to HIV infection and antiretroviral treatment in 327 individuals with HIV and 260 control participants in cohorts from Uganda, Botswana and the USA via faecal metagenomics. We found that while HIV-associated taxonomic differences were mostly site specific, changes in microbial functional pathways were broadly consistent across the cohorts and exacerbated in individuals with acquired immunodeficiency syndrome. Microbiome perturbations associated with antiretroviral medications were also geography dependent. In Botswana and Uganda, use of the non-nucleoside reverse transcriptase inhibitor efavirenz was linked to depletion of Prevotella, disruption of interspecies metabolic networks, exacerbation of systemic inflammation and atherosclerosis. Efavirenz-associated Prevotella depletion may occur through cross-inhibition of prokaryotic reverse transcriptases involved in antiphage defences, as shown by computational and in vitro experiments. These observations could inform future geography-specific and microbiome-guided therapy.

abstract = {Human immunodeficiency virus (HIV) infection alters gut microbiota composition and function, but the impact of geography and antiretroviral therapy remains unclear. Here we determined gut microbiome alterations linked to HIV infection and antiretroviral treatment in 327 individuals with HIV and 260 control participants in cohorts from Uganda, Botswana and the USA via faecal metagenomics. We found that while HIV-associated taxonomic differences were mostly site specific, changes in microbial functional pathways were broadly consistent across the cohorts and exacerbated in individuals with acquired immunodeficiency syndrome. Microbiome perturbations associated with antiretroviral medications were also geography dependent. In Botswana and Uganda, use of the non-nucleoside reverse transcriptase inhibitor efavirenz was linked to depletion of Prevotella, disruption of interspecies metabolic networks, exacerbation of systemic inflammation and atherosclerosis.

Evaluation of pharmacokinetic interactions between long-acting cabotegravir or emtricitabine/tenofovir disoproxil fumarate and hormonal contraceptive agents: a tertiary analysis of South African participants in HPTN 084.
Journal of the International AIDS Society, 28(11):e70056.
INTRODUCTION: HPTN 084 found that long-acting cabotegravir (CAB-LA) was well-tolerated and significantly reduced the risk of HIV acquisition in women compared to tenofovir disoproxil fumarate/emtricitabine (F/TDF). During the blinded phase of the trial, participants were required to use an effective method of contraception, including an injectable or implantable hormonal contraceptive (HC) agent. A contraceptive sub-study assessed the pharmacokinetic interactions between pre-exposure prophylaxis agents (CAB-LA or F/TDF) and etonogestrel (ENG), medroxyprogesterone acetate (MPA) or norethindrone enanthate (NET-EN).
METHODS: Participants were enrolled in a nested sub-study between 24 February 2020 and 26 October 2020. Via a convenience sampling strategy, plasma concentrations of ENG, MPA and NET-EN were evaluated at enrolment and weeks 25, 49 and 73; plasma tenofovir (TFV) and CAB concentrations were determined at contemporaneous visits. Participants were allowed to switch contraceptives, and HC assessments were adjusted accordingly. Geometric mean concentrations were calculated and compared using t-tests or Fisher's exact tests.
RESULTS: One hundred and seventy participants were included in this analysis. Hormone concentrations at all study visits were comparable between the CAB-LA and F/TDF study arms. Among participants randomized to the CAB-LA arm, geometric mean concentrations declined from enrolment to the follow-up period for ENG (335 to 202 pg/ml), MPA (1520 to 1138 pg/ml) and NET-EN (3715 to 1888 pg/ml); similar findings were observed among participants randomized to the F/TDF arm. Observed HC declines are likely attributed to the timing of contraceptive administration relative to sampling; the percentage of participants with hormone concentrations above thresholds associated with ovulation suppression was high (73-100%) and did not differ between arms. CAB concentrations were comparable across contraceptive types, with 97.8-98.1% of participants yielding trough CAB concentrations above the protocol-specified target threshold. TFV concentrations were unquantifiable for most participants, irrespective of contraceptive agent, rendering comparisons largely uninformative.
CONCLUSIONS: Given the comparable hormone concentrations between arms and the likely influence of the timing of sample collection on observed measurements, clinically significant interactions between CAB-LA and HC are not expected. Associations between F/TDF and hormone concentrations could not be effectively evaluated due to low adherence to F/TDF.

Total Body Irradiation Versus Chemotherapy-Only Conditioning in Autologous Haematopoietic Stem Cell Transplantation for Relapsed/Refractory Large B-cell Lymphoma.
Clinical oncology (Royal College of Radiologists (Great Britain)), 48:103959.
AIMS: In the era of chimeric antigen receptor T-cell (CAR-T) therapy, there remains a role for autologous stem cell transplant (ASCT) for patients with large B-cell lymphoma (LBCL) without access to CAR T-cell therapy or who have late, chemosensitive relapse (>12 months). Typically, the ASCT conditioning regimen is chemotherapy only. Given the radioresponsiveness of LBCL, we retrospectively evaluated whether ASCT outcomes are improved with total body irradiation (TBI)-based conditioning compared to chemo-only conditioning.
MATERIALS AND METHODS: We included patients with relapsed/refractory (r/r) LBCL who underwent ASCT at our centre (2012-2021). As TBI is generally offered only to younger patients, we excluded patients in the chemo-only group who were older than the oldest patient in the TBI group, leaving 56 patients in the final dataset (TBI: 19; chemo: 37).
RESULTS: The TBI cohort had more adverse features including male sex (89.5% vs 62.2%), relapse ≤12 months (52.6% vs 32.4%), and shorter time between diagnosis and ASCT (median: 11.7 vs 21.8 months). Two-year progression-free survival (PFS) was 58% (95% confidence interval [CI]: 39%-85%) and 67% (53%-84%) in TBI and chemotherapy cohorts, respectively. Two-year overall survival (OS) was 79% (63%-100%) and 80% (68%-95%) in TBI and chemotherapy cohorts, respectively. Multivariable hazard ratio (HR) of PFS failure (TBI vs chemo) was 1.35 (95% CI: 0.59-3.12). The HR of death was 1.33 (95% CI: 0.49-3.58). While conditioning regimen was not associated with PFS, positron emission tomography (PET) positivity at time of ASCT (HR: 6.97, 95% CI: 2.98-16.27, P < 0.001) was associated with PFS failure.
CONCLUSION: Despite the presence of more adverse features among patients treated with TBI, there was no difference in PFS or OS among patients that underwent chemo-only vs TBI-based conditioning. Though hypothesis generating, this suggests that TBI may be able to partially compensate for adverse fatures.

Safety outcomes among infants whose mothers used the dapivirine vaginal ring or oral PrEP during pregnancy (MTN-042/DELIVER): a randomised phase 3b study.
The lancet. HIV, 12(11):e763-e773.
BACKGROUND: HIV acquisition risk during pregnancy remains high and additional data supporting pre-exposure prophylaxis (PrEP) in pregnancy are needed. The aim of the MTN-042/DELIVER study was to evaluate the dapivirine vaginal ring (DVR) and daily oral tenofovir disoproxil fumarate plus emtricitabine use as PrEP during pregnancy. We report infant outcomes following confirmed in-utero exposure.
METHODS: This randomised, controlled, open-label, phase 3b study was conducted in four clinical research sites in Malawi, South Africa, Uganda, and Zimbabwe. Pregnant, HIV-negative, healthy women aged 18-40 years were enrolled at 36-37 weeks' (cohort 1), 30-35 weeks' (cohort 2), and 12-29 weeks' (cohort 3) gestation and randomly assigned 2:1 (cohorts 1 and 2) and 4:1 (cohort 3) to receive the DVR (dapivirine 25 mg) or oral PrEP (tenofovir disoproxil fumarate 300 mg plus emtricitabine 200 mg). All infants born to maternal participants were enrolled and included in the primary infant analysis to evaluate infant safety with in-utero exposure to study product. Infant visits were conducted at less than 2 weeks, 6 weeks, 6 months, and 12 months of age. The primary infant composite safety outcome included serious adverse events and grade 3 or higher adverse events. Birth outcomes (livebirth or stillbirth, prematurity), adverse events (including frequency between each study visit), and growth up to 12 months were evaluated and collected. This study is registered with ClinicalTrials.gov (NCT03965923). The trial is completed and the database closed.
FINDINGS: The study was conducted between Feb 7, 2020, and May 13, 2024. In total, 545 infants were included: 147 in cohort 1, 154 in cohort 2, and 244 in cohort 3. Mean intrauterine exposure was 23·3, 59·7, and 113·8 days, respectively. Overall, 545 (99%) of 550 pregnancy outcomes were livebirths. Serious adverse events occurred in 66 (17%) of 398 infants in the DVR group and 15 (10%) of 147 in the oral PrEP group. Grade 3 or higher adverse events occurred in 95 (24%) of 398 and 29 (20%) of 147 infants, respectively, none related to product exposure. 41 (51%) of 81 new-onset serious adverse events occurred by age 6 weeks, and ten (91%) of 11 congenital anomalies were diagnosed by age 6 months. There were no maternal or infant HIV acquisitions.
INTERPRETATION: Over 12 months of follow-up of infants, the DVR and oral PrEP were generally safe, with no composite adverse events related to study product. Together with available maternal safety data, this supports use of the DVR and oral PrEP by pregnant women to prevent HIV.

Osimertinib retreatment for patients with advanced EGFR-mutated non-small cell lung cancer.
Cancer treatment and research communications, 45:101026.
Resistance to osimertinib, a third-generation EGFR tyrosine kinase inhibitor, remains a key challenge in the treatment of EGFR-mutated non-small cell lung cancer (NSCLC). Although retreatment with earlier-generation EGFR tyrosine kinase inhibitors has been studied, data on osimertinib rechallenge are limited. We conducted a single institution retrospective analysis of patients with EGFR-mutated NSCLC who were rechallenged with osimertinib following progression on prior osimertinib and interim systemic therapy, including chemotherapy. Seventeen patients met inclusion criteria, all with adenocarcinoma histology and either EGFR exon 19 deletions or L858R mutations. Median interval between osimertinib treatments was 10.5 months. Osimertinib retreatment resulted in a partial response in 18 % (3/17) and stable disease in 35 % of patients (6/17), for a disease control rate of 53 % (9/17). Median retreatment duration was 4.3 months, and median overall survival following retreatment initiation was 8.9 months. Among patients with central nervous system involvement, several experienced intracranial stability without additional radiation. Duration of initial osimertinib therapy did not strongly predict retreatment benefit. These findings suggest that osimertinib rechallenge may provide clinically meaningful disease control in a subset of patients, especially given its tolerability and oral formulation. Further research is needed to identify biomarkers of sensitivity and to optimize patient selection for osimertinib retreatment following interval chemotherapy.

We conducted a single institution retrospective analysis of patients with EGFR-mutated NSCLC who were rechallenged with osimertinib following progression on prior osimertinib and interim systemic therapy, including chemotherapy. Seventeen patients met inclusion criteria, all with adenocarcinoma histology and either EGFR exon 19 deletions or L858R mutations. Median interval between osimertinib treatments was 10.5 months. Osimertinib retreatment resulted in a partial response in 18 % (3/17) and stable disease in 35 % of patients (6/17), for a disease control rate of 53 % (9/17). Median retreatment duration was 4.3 months, and median overall survival following retreatment initiation was 8.9 months. Among patients with central nervous system involvement, several experienced intracranial stability without additional radiation. Duration of initial osimertinib therapy did not strongly predict retreatment benefit. These findings suggest that osimertinib rechallenge may provide clinically meaningful disease control in a subset of patients, especially given its tolerability and oral formulation. Further research is needed to identify biomarkers of sensitivity and to optimize patient selection for osimertinib retreatment following interval chemotherapy.},

DARolutamide ObservationaL (DAROL) study in patients with nonmetastatic castration-resistant prostate cancer: prespecified third interim analysis.
Prostate cancer and prostatic diseases [Epub ahead of print].
BACKGROUND: DAROL is an ongoing study of real-world safety and effectiveness of darolutamide in patients with nonmetastatic castration-resistant prostate cancer (nmCRPC).
SUBJECTS/METHODS: This prespecified interim analysis included 550 patients with nmCRPC who completed ≥6 months of treatment with darolutamide 600 mg twice daily.
RESULTS: Darolutamide showed consistent safety and effectiveness in DAROL vs ARAMIS. Most treatment-emergent adverse events were grade 1/2. Two-year overall survival and metastasis-free survival rates and prostate-specific antigen responses were similar to ARAMIS.
CONCLUSIONS: These findings indicate that darolutamide offers effectiveness and a favorable safety profile in the broad range of patients seen in clinical practice.

Hydrogel formulations for sustained-release of broadly neutralizing antibodies.
Journal of controlled release : official journal of the Controlled Release Society, 388(Pt 2):114349.
Sustained serum levels of broadly neutralizing antibodies (bnAbs) are crucial for effective passive immunization against infectious diseases as protection persists only while these bnAbs remain at adequate concentrations within the body. Current obstacles, such as poor pharmacokinetics (PK) and burdensome administration, must be overcome to make bnAbs a viable option for pre- and post-exposure prophylaxis. In this work, we explore how a polymer-nanoparticle (PNP) hydrogel depot technology can be engineered to prolong protein delivery and enable drug exposure on the order of weeks to months. In-vivo studies in mice and rats demonstrate extended protein release compared to bolus administration, and modeling efforts predict the impact of both the elimination half-life of the active pharmaceutical ingredient and hydrogel depot volume on overall pharmacokinetics. Moreover, flow cytometry characterization reveals that immune cell infiltration into the hydrogel depot can result in faster-than-expected release of antibody cargo on account of active transport via cellular uptake. We then demonstrate that co-formulation of antibodies with an anti-inflammatory agent reduces cellular infiltration and resulting active transport, further extending delivery and pharmacokinetics. Finally, multicompartmental modeling predicts the human PK profiles of clinically relevant HIV bnAbs delivered via subcutaneous hydrogel injection. These findings aid in the development of next generation hydrogel materials that stabilize and slowly release bnAbs for long-term pre-exposure immunoprophylaxis.

Reporting and enrollment disparities in hematologic malignancy trials between 2000-2023.
Leukemia & lymphoma, 67(1):176-189.
Despite initiatives to enhance diversity in clinical trials (CTs), disparities persist in hematologic malignancy (HM) studies. We reviewed 1,230 US-based phase II-III HM CTs (2000-2023) including 149,434 participants and compared enrollment to SEER benchmarks. Race was reported in 59% of trials and ethnicity in 40%, with significant improvement over time. Trials initiated in 2016 or later were more likely to report race (OR 36.3) and ethnicity (OR 8.0) than those before 2008. Compared with NIH-sponsored studies, institutional (OR 0.34) and industry trials (OR 0.52) had lower odds of reporting demographics. Black and Hispanic individuals were consistently underrepresented, most notably in multiple myeloma (7.0% vs. 20.0% expected) and acute lymphoblastic leukemia (21.5% vs. 36.9% expected). NIH-funded trials enrolled more Black participants than other sponsor types. These findings emphasize the need for enforceable mandates on race and ethnicity reporting, as well as representation targets, to ensure equitable access and generalizability.

Cytomegalovirus Viral Load Continues to Predict Poor Outcomes in Adults and Children Despite Improved Hematopoietic Cell Transplantation Success.
Open forum infectious diseases, 12(11):ofaf612.
BACKGROUND: Recent advances of graft-versus-host disease prevention strategies have led to improved overall survival after hematopoietic cell transplantation (HCT). Whether cytomegalovirus (CMV) viral load continues to predict CMV disease, overall mortality, and nonrelapse mortality is poorly defined.
METHODS: CMV-seropositive patients undergoing allogeneic HCT between 2007 and 2017 with weekly CMV DNA polymerase chain reaction surveillance and preemptive therapy were analyzed. Multivariate Cox proportional hazards models were used to estimate the association between CMV viral load by day 100 at different thresholds with CMV disease and overall and nonrelapse mortality up to 1 year post-HCT.
RESULTS: Of 1539 patients who received a transplant in the study period, 1349 survived >100 days after HCT and were included in the analyses. By day 100 post-HCT, CMV reactivation at any level was observed in 76%, with the lowest incidence at all levels in young children. Pediatric patients had significantly less CMV disease compared to the adult population. CMV reactivation was associated with a higher risk of CMV disease (adjusted hazard ratio, 6.8 [95% confidence interval, 3.54-13]); it was also associated with overall and nonrelapse mortality among day 100 survivors, although the association was diminished recently. The strongest correlation was still apparent between viral load and mortality in patients with a viral load >3 log10 and lymphocyte count <300 cells/μL.
CONCLUSIONS: CMV viral load continued to be a strong predictor for CMV disease. With improved transplantation techniques, the association of viral load with overall and nonrelapse mortality is diminished, but the effect was still present in patients with severe immunosuppression.

Sustained HIV Suppression With Co-formulated Tenofovir Disoproxil Fumarate/Lamivudine/Dolutegravir in a Person With Transmitted Dolutegravir Resistance and Pretreatment Resistance to Lamivudine: a Case Report From HPTN 083.
Open forum infectious diseases, 12(11):ofaf645.
Integrase strand transfer inhibitors (INSTIs) are recommended in most first-line HIV treatment regimens. We describe a participant in a clinical trial with transmitted INSTI resistance. The participant had no history of INSTI use and had no evidence of INSTI exposure prior to HIV acquisition. Treatment with tenofovir disoproxil fumarate, lamivudine (3TC), and dolutegravir (DTG) was started 3 weeks after HIV diagnosis. Viral suppression was achieved within a year and was sustained for >3 years on treatment. Retrospective HIV genotyping of a pretreatment sample detected major resistance mutations in 3 drug classes, with predicted high-level resistance to DTG and 3TC. HIV phenotyping confirmed that the transmitted virus had DTG and 3TC resistance but retained susceptibility to DTG at higher drug concentrations. Pharmacologic testing indicated that the DTG concentrations observed in this case were sufficient to overcome the effects of 2 major baseline INSTI resistance mutations (G140S and Q148H).

Circulating inflammatory biomarkers and endometriosis lesion characteristics in the WisE consortium.
npj women's health, 3(1):62.
Endometriosis is a chronic inflammatory condition requiring surgical or imaging visualization for definitive diagnosis. How endometriotic lesion characteristics relate to circulating inflammatory markers remains unclear. We evaluated 11 inflammatory biomarkers, including interleukin (IL)-1β, -6, -8, -10, -16, tumor necrosis factor (TNF)-α, thymus and activation regulated chemokine (TARC), monocyte chemotactic protein (MCP)-1, -4, and Interferon gamma-induced protein (IP)-10, in 566 participants with endometriosis from the Women's Health Study: From Adolescence to Adulthood (A2A), Endometriosis Oxford Care & Research (CaRe) study (ENDOX) and Endometriosis: Natural History, Diagnosis, and Outcome (ENDO) study to evaluate associations with endometriosis characteristics, including macrophenotype (superficial lesions only, versus endometrioma and/or deep lesions), lesion appearance (color, vascularity), and anatomic location. We observed nominally statistically significant variation in circulating inflammatory markers by lesion color, vascularity, and location but no significant associations between circulating inflammatory markers and rASRM stage or macrophenotype, which could be due to a small number of participants with non-superficial lesions.

Cost-effectiveness of biomarker-based and universal strategies for the treatment of advanced-stage endometrial cancer.
Gynecologic oncology, 203:130-138.
OBJECTIVE: To compare cost-effectiveness of targeted therapeutic strategies for non-Hispanic Black (NHB) and non-Hispanic White (NHB) patients with newly diagnosed, advanced-stage endometrial cancer.
METHODS: A Markov-based cost-utility model using a third-party payer perspective compared concurrent and maintenance treatment strategies incorporating dostarlimab and trastuzumab for newly diagnosed stage III-IV endometrial cancer: chemotherapy alone; 3 universal immunotherapy strategies (universal concurrent and maintenance dostarlimab +/- trastuzumab for HER2/neu-positive serous and/or carcinosarcomas); and 3 targeted immunotherapy strategies (dostarlimab for mismatch repair deficient (dMMR) tumors +/- trastuzumab for HER2/neu positive serous and/or carcinosarcomas). Costs (2024 USD), utilities, and clinical estimates were derived from published literature and the National Cancer Database. The base case analysis was a microsimulation with 10,000 runs, accompanied by a Monte Carlo probabilistic sensitivity analysis with 20,000 trials. Cost-effectiveness was assessed using incremental cost-effectiveness ratios (ICERs) with a willingness-to-pay threshold of $150,000/quality-adjusted life year (QALY). We performed one-way and two-way sensitivity analyses on key parameters and analyses stratified by race/ethnicity.
RESULTS: All targeted immunotherapy strategies were cost-effective compared to chemotherapy alone in both NHB and NHW, while universal immunotherapy was never cost-effective. Targeted strategies were more cost-effective in NHB than NHW. Targeted dostarlimab for dMMR plus trastuzumab for HER2 serous and carcinosarcomas was the most cost-effective strategy compared to chemotherapy, with an ICER of $119,945/QALY. In sensitivity analysis, assuming longer durations of treatment benefit resulted in lower ICERs.
CONCLUSIONS: Personalized treatment strategies incorporating HER2 and MMR testing should be considered to optimize both cost-effectiveness and equity in care.

Transcriptome-wide association studies at cell-state level using single-cell eQTL data.
Cell genomics, 6(1):101060.
Transcriptome-wide association studies (TWASs) are widely used to prioritize genes for diseases. Current methods test gene-disease associations at the bulk tissue or cell-type-specific pseudobulk level, which do not account for the heterogeneity within cell types. We present TWiST, a statistical method for TWAS at cell-state resolution using single-cell expression quantitative trait locus (eQTL) data. Our method uses pseudotime to represent cell states and models the effect of gene expression on the trait as a continuous pseudotemporal curve. Therefore, it allows flexible hypothesis testing of global, dynamic, and nonlinear associations. Through simulation studies and real data analysis, we demonstrated that TWiST leads to significantly improved power compared to pseudobulk methods. Application to the OneK1K study identified hundreds of genes with dynamic effects on autoimmune diseases along the trajectory of immune cell differentiation. TWiST presents great promise to understand disease genetics using single-cell studies.

Does living near a tobacco retailer impact the efficacy of smoking cessation treatments?: Analysis from a randomized trial.
Addictive behaviors reports, 22:100635.
INTRODUCTION: Whether living near a tobacco retailer impacts the efficacy of smoking cessation treatments remains largely unknown. We used data from a randomized trial comparing two smoking cessation apps among 2415 adults: iCanQuit, based on Acceptance and Commitment Therapy, and QuitGuide, based on standard U.S. Clinical Practice Guidelines. We examined whether tobacco retailer density impacted the efficacy of the treatments on 12-month cessation outcomes.
METHODS: Data on tobacco retailer density per 1,000 people (i.e., "one unit") was linked to each participant's residential ZIP Code. Cessation outcomes included 30-day point prevalence abstinence (PPA) from cigarette smoking, prolonged abstinence, 30-day PPA from nicotine/tobacco products, and relapse. We examined the interaction between density and treatment arm on 12-month 30-day PPA and compared cessation outcomes separately by arm.
RESULTS: The interaction between density and treatment arm on cessation did not reach statistical significance (P = 0.09). For each one-unit increase in density, there was no change in quit rates in the iCanQuit arm (P = 0.62). In the QuitGuide arm, higher density was associated with lower quit rates (OR = 0.54; 95 % CI, 0.27-1.06; P = 0.07), although not-statistically significant. There was a significant interaction between density and treatment arm on prolonged cigarette abstinence (P = 0.03). We found no change in prolonged abstinence in the iCanQuit arm (P = 0.44). In the QuitGuide arm, higher density was associated with lower prolonged abstinence (OR = 0.27; 95 % CI, 0.07-1.02; P = 0.054), although not-statistically significant. Conclusions: Living near tobacco retailers may undermine the effectiveness of standard behavioral treatment but appears to have no impact on the effectiveness of acceptance-based smoking cessation treatments.

Reproducibility and repeatability of the Myoton to quantify sclerotic chronic graft-versus-host disease.
Blood advances, 10(4):1145-1152.
There is an urgent need for validated tools to measure sclerotic cutaneous chronic graft-versus-host disease (scGVHD). We examined the interobserver reproducibility within a session and intraobserver repeatability between sessions of the Myoton device for quantifying skin sclerosis in 36 adults with scGVHD. The Myoton was used to measure oscillation frequency and relaxation time of soft tissues at 7 bilateral sites (14 anatomic sites) by 2 study personnel at 2 study sessions. Agreement was measured using mean pairwise absolute difference (MPD), and reliability was measured using intraclass correlation coefficient (ICC). For each of the 2 Myoton parameters, the overall interobserver MPD was <5% of the average overall values and the interobserver ICC was >0.90 between the 2 observers, indicating excellent agreement and reliability within a measurement session. The median time between sessions 1 and 2 was 47.5 days. The overall normalized intraobserver MPD was <7% of the average overall values for each of the 2 Myoton parameters, reflecting good agreement between sessions. The intraobserver ICC for frequency and relaxation time parameters were 0.85 and 0.84, respectively, indicating good reliability between sessions. The reproducibility and repeatability of a bonus site selected at each study visit were similar to the standard 14 anatomic sites. However, no individual site was nearly as reproducible or repeatable as the overall Myoton measurements averaged across the patient. Our findings emphasize the utility of the Myoton for assessing skin properties in scGVHD with patient-level measurements.

National Landscape of Logistical and Nonmedical Requirements for Transplantation and Cellular Therapy.
Transplantation and cellular therapy, 32(2):209.e1-209.e13.
BACKGROUND: New disease indications and supportive care advances have expanded the populations who may benefit from cellular therapies, including autologous or allogeneic hematopoietic cell transplant (HCT) and/or chimeric antigen receptor T-cell therapy (CAR T). However, nonmedical requirements for these therapies, such as caregiver and housing availability, may limit access. We sought a detailed national assessment of nonmedical requirements for HCT and CAR T-cell therapy to describe and quantify barriers.
OBJECTIVE: Describe the national landscape and implementation of logistical and nonmedical requirements for HCT and CAR T-cell therapy.
STUDY DESIGN: We developed a web-based survey of HCT/CAR T-cell therapy requirements and obtained pilot feedback from 3 centers that regularly perform HCT/CAR T-cell therapy. We distributed the survey via the NCCN Best Practices Committee, which is composed of physician, nursing, and administrative leaders from 34 member institutions. We requested survey completion by an institutional content area expert.
RESULTS: The response rate was 91% (31/34). >80% of centers required a caregiver, local housing, and local transportation, but the number of days required, institutional supports, and acceptable distances varied widely. A subset of centers offered "all-outpatient" procedures and required more stringent logistical criteria, including autologous HCT by 13/19 centers (68%), allogeneic HCT by 4/8 centers (50%), and CAR T-cell therapy by 10/16 centers (63%). Many centers excluded patients with a history of medication nonadherence, substance use, or psychiatric comorbidity, but most did not employ formal adjudication or definition of patient eligibility. Institutions noted "soft" contraindications or case-by-case review for these patients and those experiencing homelessness, lack of insurance, or without citizenship. Overall, caregiving, housing, cost, and insurance coverage emerged as the top nonmedical barriers to HCT and CAR T-cell therapy.
CONCLUSIONS: Significant variability exists in nonmedical requirements for HCT and CAR T-cell therapy, with a lack of standard policies across institutions. We recommend that centers formally track reasons for noneligibility to identify nonmedical barriers to HCT and CAR T-cell therapy and develop targeted interventions to reduce the number of patients who are excluded for nonmedical reasons.

ACR Appropriateness Criteria® Staging and Follow-Up of Leukemia.
Journal of the American College of Radiology : JACR, 22(11S):S658-S688.
Imaging associated with staging and follow-up of leukemia can play an important role in accurately assessing disease; however, the type of imaging and usefulness varies significantly by the subtype of leukemia. This document reviews the current literature regarding the impact of imaging for both staging and surveillance of several of the most common leukemic variants. These include acute lymphoblastic leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, Richter transformation, and chronic myeloid leukemia. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Genome-scale CRISPR screens identify PTGES3 as a direct modulator of androgen receptor function in advanced prostate cancer.
Nature genetics, 57(12):3027-3038.
The androgen receptor (AR) is a critical driver of prostate cancer (PCa). Here, to study regulators of AR protein levels and oncogenic activity, we developed a live-cell quantitative endogenous AR fluorescent reporter. Leveraging this AR reporter, we performed genome-scale CRISPRi flow cytometry sorting screens to systematically identify genes that modulate AR protein levels. We identified and validated known AR protein regulators, including HOXB13 and GATA2, and also unexpected top hits including PTGES3-a poorly characterized gene in PCa. PTGES3 repression resulted in loss of AR protein, cell-cycle arrest and cell death in AR-driven PCa models. Clinically, analysis of PCa data demonstrates that PTGES3 expression is associated with AR-directed therapy resistance. Mechanistically, we show PTGES3 binds directly to AR, regulates AR protein stability and is necessary for AR function in the nucleus at AR target genes. PTGES3 represents a potential therapeutic target for overcoming known mechanisms of resistance to existing AR-directed therapies in PCa.

abstract = {The androgen receptor (AR) is a critical driver of prostate cancer (PCa). Here, to study regulators of AR protein levels and oncogenic activity, we developed a live-cell quantitative endogenous AR fluorescent reporter. Leveraging this AR reporter, we performed genome-scale CRISPRi flow cytometry sorting screens to systematically identify genes that modulate AR protein levels. We identified and validated known AR protein regulators, including HOXB13 and GATA2, and also unexpected top hits including PTGES3-a poorly characterized gene in PCa. PTGES3 repression resulted in loss of AR protein, cell-cycle arrest and cell death in AR-driven PCa models. Clinically, analysis of PCa data demonstrates that PTGES3 expression is associated with AR-directed therapy resistance. Mechanistically, we show PTGES3 binds directly to AR, regulates AR protein stability and is necessary for AR function in the nucleus at AR target genes. PTGES3 represents a potential therapeutic target for overcoming known mechanisms of resistance to existing AR-directed therapies in PCa.},

Unrelated Donor Age and Recipient Outcomes After Posttransplant Cyclophosphamide vs Conventional Prophylaxis.
JAMA oncology, 12(1):28-37 [Epub ahead of print].
IMPORTANCE: Advanced age in unrelated donors (URDs) is a well-established risk factor in allogeneic hematopoietic cell transplant (HCT), leading registries to prioritize younger donors. However, this paradigm relevance is uncertain in the era of posttransplant cyclophosphamide (PTCy) for graft-vs-host disease (GVHD) prophylaxis, a strategy increasingly adopted for its effectiveness. Clarifying this association is crucial for optimizing donor selection and potentially expanding the donor pool.
OBJECTIVE: To determine whether the association of older URD age with overall survival differs between patients receiving PTCy-based vs conventional calcineurin inhibitor (CNI)-based GVHD prophylaxis.
This was a multicenter cohort study using registry data from the Center for International Blood and Marrow Transplant Research for January 2017 through June 2021. Eligible participants were adult patients with acute leukemia or myelodysplastic syndrome who underwent an allogeneic HCT from a URD who was fully matched for 8 of 8 human leukocyte antigen loci (MUD) or mismatched for 7 of 8 human leukocyte antigen loci (MMUD). Data were analyzed from January to June 2025.
EXPOSURES: GVHD prophylaxis regimen (PTCy-based vs CNI-based) and donor age (analyzed continuously and categorically).
MAIN OUTCOMES AND MEASURES: Overall survival was the primary outcome, with associations assessed using a multipronged approach including least absolute shrinkage and selection operator (LASSO)-penalized Cox proportional hazards models, inverse probability of treatment weighting (IPTW), and XGBoost machine learning.
RESULTS: The study analysis included 10 025 patients (mean [SD] age, 56.5 [14.4] years; 4379 female [43.7%] and 5646 male [56.3%] individuals) among whom 7272 (72.5%) had received MUD-CNI; 1681 (16.8%%) MUD-PTCy; 613 (6.1%) MMUD-PTCy; and 459 (4.6%) MMUD-CNI. Increasing donor age was associated with worse OS in CNI-based MUD (hazard ratio [HR], 1.004-1.009 per year increase) and MMUD (HR, 1.022-1.034) cohorts. Conversely, this association was not observed in the combined PTCy cohort (HR, 1.001-1.007). These findings were robust across standard and overlap weighted IPTW, LASSO-penalized models, and XGBoost analyses. The attenuated association in the PTCy cohort was primarily driven by a lack of association between donor age and nonrelapse mortality.
CONCLUSIONS AND RELEVANCE: The findings of this cohort study indicate that the association of donor age with URD HCT outcomes appears to be mitigated in the PTCy setting, suggesting that PTCy may counteract some of the adverse effects associated with increased unrelated donor age. This observation challenges existing paradigms and warrants validation in independent cohorts, and if validated, could substantially expand the donor pool.

Rechallenge and Extended [[177]Lu]Lu-PSMA Therapy in Metastatic Prostate Cancer.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 67(1):4-11 pii:jnumed.125.270889.
Continuation of effective and well-tolerated systemic treatment is often performed in care for metastatic castration-resistant prostate cancer. Likewise, continued administration of [[177]Lu]Lu-PSMA radiopharmaceutical therapy beyond the approved number of cycles holds promising potential to enhance therapeutic efficacy. Rechallenge therapy involves readministration of [[177]Lu]Lu-PSMA cycles after a break, whereas extended therapy continues treatment beyond the standard 6 cycles without interruption. Both approaches aim to improve disease control and prolong survival in patients with metastatic castration-resistant prostate cancer. However, practices vary: some clinicians continue treatment in patients with early favorable responses, whereas others recommend pausing therapy after significant prostate-specific antigen declines, even after a few cycles. In this narrative review, we show that safety profiles for continued [[177]Lu]Lu-PSMA radiopharmaceutical therapy are generally favorable, and most adverse events are mild to moderate in severity. Hematotoxicity, particularly anemia and thrombocytopenia, is the most significant concern, with few patients experiencing high-grade adverse events. In addition, cumulative irradiation, particularly during extended therapy, necessitates careful monitoring of hematologic and renal function. Biochemical responses to rechallenge and extended [[177]Lu]Lu-PSMA therapy are promising, with at least 50% reductions in prostate-specific antigen levels observed in a significant proportion of highly selected patients. Moreover, survival outcomes are encouraging, showing the extension of overall and progression-free survival beyond the known data for standard therapy. Despite these advances, challenges remain in optimizing patient selection, managing cumulative toxicities, and harmonizing treatment protocols. In addition, variability in trial designs, influenced by international regulatory differences, limits the current evidence and necessitates consideration of each treatment approach within its regulatory context. Prospective studies are needed to refine therapeutic strategies, implement consistent clinical and imaging response criteria, and identify predictive biomarkers to improve both efficacy and safety.

A hybrid IGRT workflow using SGRT and CBCT for prostate SBRT: Feasibility, efficiency, and safety.
Journal of applied clinical medical physics, 26(11):e70339.
BACKGROUND AND PURPOSE: Safe delivery of prostate stereotactic body radiotherapy (SBRT) relies on precise target localization. Without access to real-time intrafraction motion management, careful optimization of IGRT protocols is necessary to safeguard treatment accuracy and patient outcomes.
METHODS: An IGRT workflow is proposed that incorporates surface-monitoring (SGRT) to complement cone-beam CT (CBCT) imaging. The study evaluates 23 consecutive SBRT prostate patients who were treated on a prospective registry study. Each patient received pre- and mid-treatment and a subset received post-treatment CBCTs. The frequency and magnitude of SGRT triggered beam interruptions as well as treatment times were recorded.
RESULTS: The median number of CBCTs acquired per fraction was four and the median treatment time was 23 min (IQR 19-27). SGRT detected intra-fraction surface-based motion beyond a combined 4 mm vector isocenter tolerance in 62% of all fractions treated, with a maximum motion of 15 mm. On average < 2 beam interruptions were triggered by SGRT per treatment fraction. There was no statistically significant correlation between overall treatment time and SGRT-triggered beam interruptions (r = 0.048, p = 0.645). There was a weak but statistically relevant correlation of overall treatment time with the maximum detected motion (r = 0.23, p = 0.026). SGRT detected five fractions where the patients had persistently moved outside the SGRT tolerance, and for three of these (60%), a CBCT verified that the target was out of tolerance.
CONCLUSION: SGRT is a valuable tool that complements CBCT-based IGRT. An SGRT motion vector tolerance of 4 mm provides a pragmatic compromise between detecting patient motion and treatment efficiency. Overall, persistent patient motion during treatment was infrequent in this cohort, however, SGRT was able to detect several cases where the internal target was outside of the tolerance highlighting that patient monitoring with SGRT can contribute to improved quality and safety for prostate SBRT.

Intratumoral Three-Cell-Type Clusters Are a Conserved Feature of Endogenous Antitumor Immunity.
Cancer immunology research, 14(2):205-218.
Effective antitumor immunity ultimately depends on the priming and activation of tumor-specific cytotoxic CD8+ T cells; however, the role of intratumoral cell-cell immune interactions remains incompletely understood. Recent work has revealed that the temporospatial co-localization of dendritic cells (DC), T helper (Th) cells, and cytotoxic T lymphocytes (CTL) within the tumor immune microenvironment following immune checkpoint blockade correlates with clinical response. In this study, we report the integration of more than 1 million spatially resolved single-cell profiles across six spatial proteomic and transcriptomic assays, which demonstrated that DC:Th:CTL three-cell-type clusters were common even in immunotherapy-naïve and highly desmoplastic tumors, such as fibrolamellar carcinoma and pancreatic ductal adenocarcinoma. We found that these immune triads were enriched for functionally important type 1 conventional DC, mature DCs enriched in immunoregulatory molecules, CXCL13+ Th, and GZMK+ effector CTL phenotypes. Subsequent multiplex immunofluorescence imaging of more than 450 primary pancreatic ductal adenocarcinoma tumors showed that the density of antigen-presenting cell:Th:CTL three-cell-type clusters was correlated with intratumoral T-cell clonal expansion and improved overall survival. These findings suggest that DC:Th:CTL triads are conserved across solid tumors and highlight the importance of intratumoral spatial niches in mediating endogenous antitumor immunity.

Cellular senescence in precancer lesions and early-stage cancers.
Cancer cell, 44(1):6-11.
Cellular senescence plays dual roles in precancer lesions: initially serving as a tumor-suppressive barrier within the epithelial compartment and later contributing to a pro-tumoral precancer tissue microenvironment (PreTME) via a sustained, paracrine secretome known as senescent-associated secretory phenotype (SASP). This commentary highlights the role of senescence across various PreTME cell types, explores emerging pharmacologic and lifestyle interception strategies, and outlines current challenges for advancing biomarkers and clinical translation.

This commentary highlights the role of senescence across various PreTME cell types, explores emerging pharmacologic and lifestyle interception strategies, and outlines current challenges for advancing biomarkers and clinical translation.},

A Virtual Mind-Body Exercise Program During Breast Radiation: Results From a Randomized Controlled Basket Trial.
International journal of radiation oncology, biology, physics, 124(4):961-970.
PURPOSE: National guidelines recommend fitness and mind-body exercise to reduce cancer-related fatigue, but substantial barriers to implementation exist. Virtual programs offer a scalable approach to address this gap. This study aims to evaluate the efficacy of a virtual fitness and mind-body exercise program (Integrative Medicine at Home [IM@Home]) in reducing fatigue in patients undergoing radiation therapy (RT) for breast cancer.
METHODS AND MATERIALS: A prospective randomized controlled patient-reported outcome basket clinical trial was conducted. Patients undergoing breast RT who reported moderate or greater fatigue were randomly assigned 1:1 ratio to either IM@Home, which provided live virtual fitness and mind-body exercise classes, or enhanced usual care (EUC). The primary outcome, fatigue, was measured using the total Brief Fatigue Inventory, a composite score including severity and impact on daily functioning, weekly over 12 weeks. Secondary outcomes included the Insomnia Severity Index, Edmonton Symptom Assessment Scale, and Hospital Anxiety and Depression Scale collected every 4 weeks. Statistical analysis included linear mixed models to compare group differences over time using a statistical significance threshold of P < .05.
RESULTS: Among 73 enrolled patients, 35 were randomly assigned to IM@Home and 38 to EUC. At week 12, patients in the IM@Home group had significantly less fatigue compared to those in the EUC group (2.06 vs 2.79, P = .009). Compared to EUC, patients in the IM@Home group showed greater reductions in insomnia (P = .005), symptom distress (P = .013), and depression (P = .04), but not anxiety (P = .14).
CONCLUSIONS: The IM@Home program significantly reduced fatigue and comorbid symptoms among women with breast cancer undergoing RT. Future research is needed to confirm these findings, explore mechanisms of the observed benefit, and evaluate scalability as well as barriers and facilitators to implementation.

Effects of acute exercise on inflammatory and metabolic biomarkers in women: a randomized controlled trial.
NPJ breast cancer, 11(1):122.
Mechanisms linking exercise to reduced breast cancer risk are poorly understood. 103 healthy women, 18-75, were randomized to 45-minutes of acute exercise at 60% VO2max (N = 54, intervention), or 45-minutes of rest (N = 49, control). Blood samples were collected at baseline, 45- and 105-minutes, analytes measured by immunoassay, and mean changes from baseline to 45- and 105-minutes modelled using generalized estimating equations, adjusted for confounders. Mean percent changes levels (Δ%) increased in exercisers vs. controls for monocyte chemoattractant protein (MCP)-1 Δ[45 min] + 17.1% (P < 0.0001), Δ[105 min] + 12.0% (P = 0.005); interleukin(IL)-6, Δ[45 min] + 103.5%, Δ[105 min] + 92.3%; and at 45-minutes for glucose Δ[45 min] + 8.8%; insulin Δ[45 min] + 82.4% (all P < 0.0001). Differences between arms for vascular endothelial growth factor (VEGF) Δ[45 min] + 9.8%; c-reactive protein Δ[45 min]-6.6%; irisin Δ[45 min]-5.1%; or plasminogen activator inhibitor (PAI)-1, Δ[45 min]-3.6% were non-statistically significant, with similar results at 105-minutes. Results suggest that acute exercise has specific effects on circulating metabolic and inflammatory biomarkers, implicated in breast cancer etiology, which differ from weight-loss-induced changes. Trial registration: Clincialtrials.gov identifier NCT03779867.

Exploring biomarkers of neurodegenerative risk: associations of oxysterols, sex hormones, and reproductive characteristics in older women.
Journal of lipid research, 66(12):100938.
Women face a higher lifetime risk of developing neurodegenerative diseases such as Alzheimer's disease and related dementias. The menopausal transition, characterized by a decline in estrogen levels, may affect cholesterol metabolism and neurodegenerative processes. Oxysterols, oxidized cholesterol derivatives, play a role in these pathways, with 24(S)-hydroxycholesterol (24HC) reflecting brain cholesterol turnover and 27-hydroxycholesterol (27HC) linked to systemic cholesterol metabolism. We investigated associations of plasma oxysterols with circulating sex hormones and characteristics of reproductive history in 1,974 postmenopausal women with no history of dementia from the Women's Health Initiative, taking into account APOE4 status and cholesterol-lowering medication. We found that higher levels of bioavailable estradiol were associated with higher 24HC and 27HC levels, and higher estrone was associated with higher 24HC (all P values <0.05). Associations of estradiol with 24HC and 27HC were stronger among APOE4 carriers and those not using cholesterol-lowering medication, with a significant interaction between bioavailable estradiol and APOE4 in relation to 27HC (p for interaction = 0.04). Having an older age at menopause was associated with lower 24HC among those taking cholesterol medication (p for interaction = 0.03). Our findings suggest that 24HC and 27HC may be proxy biomarkers of neuronal health and estrogen status in postmenopausal women. The stronger associations between estradiol and oxysterols among APOE4 carriers and those not using cholesterol medication suggest the need to account for hormonal, genetic, and pharmacological factors when evaluating neurodegenerative risk. Longitudinal studies are warranted to further investigate oxysterols as potential early biomarkers of risk for Alzheimer's disease and related dementias.

A Practical Guide to Competing Risk Analysis for Transplant and Cell Therapy Research.
Transplantation and cellular therapy, 32(4):489-500.
Competing risks are common in hematopoietic cell transplantation (HCT) and immune effector cell (IEC) therapy research. Competing risks refer to events that cannot co-occur and complicate time-to-event analyses. The typical example of competing risk in the context of HCT and IEC research is treatment-related mortality, which competes with disease relapse. In this primer, we first aim to introduce - in a clinician-friendly fashion - the core concepts underlying the statistical modelling of competing risks. Next, we propose a practical, step-by-step guide to analyze time-to-event outcomes in the context of competing risks using the open access R environment. Relevant R packages are introduced, enabling the generation of publication-ready tables and figures. We hope our manuscript will encourage more robust analyses in the fields of HCT and IEC therapy when competing risks are at play.

Estimation of Prevention-Effective CAB-LA Concentrations Among Men Who Have Sex With Men (MSM) and Transgender Women (TGW) in HPTN 083.
The Journal of infectious diseases, 233(2):e454-e461.
BACKGROUND: The HIV Prevention Trials Network (HPTN) 083 Trial demonstrated the superiority of long-acting, injectable cabotegravir (CAB) over daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) for HIV pre-exposure prophylaxis among cisgender men (MSM) and transgender women (TGW) who have sex with men. Plasma CAB concentrations associated with HIV protection in humans are unknown.
METHODS: We conducted a nested case-control study to investigate the association between plasma CAB concentrations and HIV risk. Plasma CAB concentrations were estimated for participants with confirmed HIV and for HIV-negative controls, who were matched on region, gender, and race. The window of HIV acquisition for cases was defined as the time between the last HIV-negative visit and the first HIV-positive visit; this window was used to evaluate CAB exposure for cases and their matched controls. Participants were categorized by the minimum estimated CAB concentration (CABmin) during this window relative to the protein-adjusted 90% CAB inhibitory concentration (1× PA-IC90) and 4× PA-IC90. HIV risk was modeled using conditional logistic regression.
RESULTS: Plasma CABmin was ≥4× PA-IC90 in 26% of HIV-positive cases, compared with 76% of matched controls. Plasma CABmin ≥4× PA-IC90 was associated with a 93% reduction in risk of HIV acquisition compared with CABmin <1× PA-IC90 (95% CI: 76%, 98%, P < .001). CABmin between 1× and 4× PA-IC90 had an estimated risk reduction of 79% compared with CABmin <1× PA-IC90 (95% CI: -19%, 96%, P = .07).
CONCLUSIONS: Consistent plasma CAB concentrations ≥4× PA-IC90 were estimated to provide 93% protection against HIV in MSM and TGW.

Cardiotoxic Effects of Antibody Drug Conjugates vs Standard Chemotherapy in ERBB2-Positive Advanced Breast Cancer: A Systematic Review and Meta-Analysis.
JAMA network open, 8(11):e2540336.
IMPORTANCE: Antibody-drug conjugates (ADCs), such as trastuzumab emtansine and trastuzumab deruxtecan, are effective in treating erb-b2 receptor tyrosine kinase 2 (ERBB2)-positive breast cancer (BC) that has progressed on prior ERBB2-targeted therapy, warranting evaluation of their cardiotoxic profiles.
OBJECTIVE: To compare the incidence of cardiotoxic effects of ADCs vs standard-of-care chemotherapy regimens for ERBB2-positive locally advanced or metastatic BC.
DATA SOURCES: PubMed, ScienceDirect, Cochrane Library, and ClinicalTrials.gov databases were searched in December 2024 for studies published between 2000 and 2024.
STUDY SELECTION: The included studies were (1) phase 3 clinical trials that investigated locally advanced or metastatic ERBB2-positive BC; (2) clearly defined left ventricular ejection fraction (LVEF) decrease or heart failure definitions; (3) clearly defined LVEF monitoring frequency by echocardiography or multigated acquisition scan; (4) included studies consisted solely of either trastuzumab emtansine, trastuzumab deruxtecan, or one of the first-line to fourth-line chemotherapy regimens for unresectable stage IV ERBB2-positive breast cancer per the 2025 National Comprehensive Cancer Network guidelines; and (5) clearly defined cardiovascular eligibility criteria.
DATA EXTRACTION AND SYNTHESIS: Data from eligible studies were extracted by 3 reviewers. A random-effects model was used for the pooled analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed.
MAIN OUTCOMES AND MEASURES: The primary outcome was cardiotoxic effects, which were defined as the incidence of LVEF decrease. The pooled analysis was performed using logit-transformed proportions with the inverse variance method and a DerSimonian-Laird random-effects model for between-study variance, with Wilson score 95% CIs.
RESULTS: In this meta-analysis of 9538 patients, a pooled analysis demonstrated a 0.94% (95% CI, 0.56%-1.57%) incidence of LVEF decrease with trastuzumab emtansine, a 4.20% (95% CI, 2.91%-6.01%) incidence with trastuzumab deruxtecan, a 4.85% (95% CI, 3.73%-6.28%) incidence with trastuzumab plus chemotherapy, and a 5.52% (95% CI, 3.41%-8.83%) incidence with trastuzumab plus pertuzumab plus chemotherapy. A trim-and-fill analysis was used if evidence of publication bias was found.
CONCLUSIONS AND RELEVANCE: This meta-analysis found that trastuzumab emtansine was associated with the lowest incidence of LVEF decrease, and trastuzumab deruxtecan, trastuzumab plus chemotherapy, and trastuzumab plus pertuzumab plus chemotherapy had similar incidences. More research is needed into the cardiotoxic effects of these therapies.

A trim-and-fill analysis was used if evidence of publication bias was found.
CONCLUSIONS AND RELEVANCE: This meta-analysis found that trastuzumab emtansine was associated with the lowest incidence of LVEF decrease, and trastuzumab deruxtecan, trastuzumab plus chemotherapy, and trastuzumab plus pertuzumab plus chemotherapy had similar incidences. More research is needed into the cardiotoxic effects of these therapies.},

A proposed path to explaining the unexplained anemia of aging.
The journals of gerontology. Series A, Biological sciences and medical sciences, 81(1):.
Approximately 17% of people aged 65 years and older are anemic, and 10% of death certificates report anemia as a secondary cause of death in the United States. Nonetheless, anemia remains unexplained in 30%-50% of older adults. This unexplained anemia of aging (UAA) is a diagnosis of exclusion. The mechanism, impact, and progression of UAA remain unknown. At older ages, anemia adds to pre-existing co-morbidities with significant adverse health consequences, representing a compelling unmet clinical concern. The National Institute on Aging held a workshop in 2024 to discuss current knowledge and research opportunities. Topics included the epidemiology of anemia at older age and its clinical implications; probable mechanism(s) underlying UAA, that is, low-grade inflammation's effects on erythropoiesis; the role of microbiota in iron regulation in bone marrow; the importance of ruling out a diagnosis of leukemic clonal hematopoiesis (CH), which is more prevalent in older age; the role of senescence and aging governing hematopoiesis; and the effects of sex hormones on hematopoietic stem cell aging. Understanding the roles of these factors could reduce the proportion of the older anemic population whose anemia remains unexplained and offer insights into new potential diagnostic and intervention strategies. Speakers reviewed previous clinical trials in patients with UAA and CH. They discussed lessons learned and future research priorities, including efforts to develop new diagnostic algorithms and potential uses of machine learning.

Different diabetes types and pancreatic ductal adenocarcinoma: a Mendelian randomization and pathway/gene-set analysis.
Journal of the National Cancer Institute, 118(3):437-447.
BACKGROUND: The associations between different types of diabetes, characterized by distinct pathophysiology and genetic architecture, and pancreatic ductal adenocarcinoma (PDAC) risk are not understood.
METHODS: We investigated associations of genetic susceptibility to type 2 diabetes (T2D), 8 T2D mechanistic clusters, type 1 diabetes (T1D), and maturity-onset diabetes of the young (MODY) with PDAC risk. We used genome-wide association study (GWAS) summary-level statistics for T2D (242 283 cases, 1 569 734 controls), T1D (18 942 cases, 501 638 controls), and PDAC (10 244 cases and 360 535 controls) in individuals of European ancestry.
RESULTS: Two-sample Mendelian randomization (MR) using the Robust Adjusted Profile Score (MR-RAPS) method indicated that genetically predicted T2D was associated with PDAC risk (OR = 1.10; 95% CI = 1.05 to 1.15), particularly the T2D obesity (OR = 1.28; 95% CI = 1.15 to 1.42) and lipodystrophy (OR = 1.25; 95% CI = 1.03 to 1.51) clusters. No association was observed for T1D with PDAC risk (OR = 1.01; 95% CI = 0.99 to 1.02). Pathway/gene-set analysis using the summary-based Adaptive Rank Truncated Product (sARTP) method revealed a significant association between the MODY gene-sets and PDAC risk (P = 1.5 × 10-8), which remained after excluding 20 known PDAC GWAS loci (P = 7.6 × 10-4). HNF1A, FOXA3, and HNF4A were the top contributing genes after excluding the previously identified GWAS loci regions.
CONCLUSIONS: Our results from this genetic association study support that T2D, particularly the obesity and lipodystrophy mechanistic clusters, and MODY genomic susceptibility regions play a role in the etiology of PDAC.

Toward Better and More Effective Clinical Trials for Chronic Graft-Versus-Host Disease.
Transplantation and cellular therapy, 32(4):388-397.
While the incidence of chronic Graft-versus-Host Disease (chronic GVHD) is declining due to advances in prophylaxis and survival is improving due to better supportive care, first-line treatment of chronic GVHD continues to be based on corticosteroids. Numerous attempts to establish more effective or less toxic treatment alternatives have largely failed, likely due to the biological heterogeneity of chronic GVHD and uncontrolled use of systemic corticosteroids, indicating the need for new approaches. The 2020 NIH consensus conference proposed the systematic evaluation of steroid-free initial treatment combining clinical and biological assessment to establish personalized approaches. While the first generation of trials evaluating steroid-free single agent first-line therapy approaches are recruiting, they are still not able to consider the biological heterogeneity of chronic GVHD in deciding therapeutic approaches. To advance the field, we propose a two-stage adaptive trial design starting with an intervention under consideration followed by a replication phase after the first phase has identified candidate clinical features and or biomarker predicting success. For second and subsequent lines of treatment, current treatment decisions regarding the use of the four FDA approved agents are based on the product label or a trial-and-error approach, sometimes in combination regimens despite the lack of prospective data. Future trials and prospective observational studies should focus on the development of predictive markers to provide a biological rationale for sequencing treatment options and to identify synergistic combination treatments. The recently released FDA draft guidance document for developing drugs and treatments in GVHD serves as the starting point for clinical trials planning that should yield results during the next several years.

Recommendations for Defining Chimeric Antigen Receptor T-Cell (CAR T) Dose-Limiting Toxicities (DLTs) for Future Early-Phase CAR T Therapy Studies.
Transplantation and cellular therapy pii:S2666-6367(25)01554-4 [Epub ahead of print].
Chimeric antigen receptor T-cell (CAR T) therapies have demonstrated potential to provide long-term remission in incurable hematologic malignancies, and novel approaches for CAR T therapy continue to be developed for treating cancer and other indications. Acute class-effect toxicities, such as cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, and immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome, remain significant concerns despite their potential reversibility. Given the complexities of balancing safety and efficacy of CAR T therapies, the US Food and Drug Administration (FDA) recently published Guidance for Industry, which included suggested definitions for dose-limiting toxicities (DLTs) for clinical trials of emerging CAR T therapies. However, the DLT definitions in the guidance do not reflect what was used in the phase 1 and/or registrational studies for the approved CAR Ts; for example, these studies defined DLTs as treatment-related, included exceptions, and/or allowed for time to resolve the adverse event. Using DLT definitions from the guidance could have prematurely stopped the early-phase studies of the now approved CAR Ts. In 2023, while designing a first-in-human, phase 1 study of a logic-gated cell therapy, an expert panel of academic cell therapists collaborated with industry partners at A2 Biotherapeutics to assess the practical implications of the FDA guidance. This led the panel to draft the revised recommendations contained herein, which integrate the permissibility of reversible events during dose-escalation for trial sponsors, investigators, health authorities, and other parties who may be involved in future CAR T therapy trials. These expert recommendations balance the safety of patients in early-phase trials with the potential long-term therapeutic opportunities for patients with terminal malignancies.

Pulmonary Complications Following Hematopoietic Cell Transplantation in Patients with Myelofibrosis: A Single-Center Retrospective Cohort Analysis.
Transplantation and cellular therapy, 32(3):300.e1-300.e11.
Myelofibrosis (MF) is a clonal hematopoietic stem cell disorder that frequently results in extramedullary hematopoiesis. Hematopoietic cell transplantation (HCT) is the only cure. While a 2-fold increase in pneumonia and respiratory-related mortality was recently reported in MF patients compared to the general population, the incidence and etiology of HCT-related pulmonary complications have not been well studied. We performed a retrospective chart review of consecutive MF patients who underwent HCT between 2002 and 2022. Patients with evidence of pulmonary impairment on pulmonary function tests, defined as a ≥10-point decline in forced expiratory volume in 1 second (FEV1) compared to pre-HCT and/or a decline in the FEV1/forced vital capacity (FVC) ratio to <0.7, received further chart review to determine the etiology of this decline. Of 228 patients evaluated, 126 (55%) met either the FEV1 or FEV1/FVC criteria for pulmonary impairment. After further chart review, 35 patients (15.4%) were diagnosed with broncholitis obliterans (BOS) by a pulmonologist or graft-versus-host disease specialist. Other common causes of impairment included respiratory infections (n =10), cryptogenic organizing pneumonia (n = 8), and deconditioning (n = 8). MF patients have a >50% likelihood of developing pulmonary impairment following HCT and a higher-than-expected incidence of BOS. This study supports increased pulmonary monitoring post-HCT in patients with MF.

Tyrosine Kinase Inhibitors Outperform Immune Checkpoint Inhibitors in Bone-Predominant Metastatic Renal Cell Carcinoma: A Multicenter Real-World Analysis.
Journal of Cancer, 16(14):4047-4054.
Background: Bone-predominant metastatic renal cell carcinoma (mRCC) presents significant clinical challenges due to its associated morbidities and poor prognosis. Optimal first-line treatment remains unclear, largely because these patients are often excluded from clinical trials due to difficulties in measuring bone lesions. Emerging evidence suggests that bone metastases exhibit high angiogenesis gene signatures, potentially predicting favorable responses to tyrosine kinase inhibitors (TKIs). Methods: We conducted a multicenter retrospective analysis of patients with bone-predominant mRCC treated at The Ohio State University Comprehensive Cancer Center and Fred Hutchinson Cancer Center from January 2008 to June 2021. Bone predominance was defined as having a greater number of osseous metastases compared to extra-osseous sites using computed tomography or bone scans. Patients receiving first-line TKIs or immune checkpoint inhibitors (ICIs) were included; those treated with combination TKI-ICI therapies were excluded due to limited numbers. Demographic, clinical, and treatment data were collected. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier methods and compared using the log-rank test. Univariate Cox regression analysis was conducted to identify factors associated with OS. Results: A total of 69 patients with bone-predominant mRCC were identified, with 40 receiving TKIs and 29 receiving ICIs as first-line therapy. Baseline characteristics were comparable between groups. The median OS was significantly longer for patients treated with TKIs compared to those receiving ICIs (41.3 months vs. 19.3 months; log-rank P = 0.036). A trend toward improved median PFS was observed in the TKI group (7.9 months vs. 4.9 months; P = 0.075). Univariate analysis showed that treatment with ICIs was associated with an increased risk of death compared to TKIs (hazard ratio = 1.96; P = 0.040). Objective response rates were higher in the TKI group (22.9% vs. 12.0%), although this difference was not statistically significant (P = 0.332). Conclusions: In this multicenter real-world analysis, first-line treatment with TKIs was associated with significantly improved OS compared to ICIs in patients with bone-predominant mRCC. These findings suggest that TKI-containing regimens may be the preferred front-line therapy for this patient subgroup. Prospective studies are warranted to validate these results and to optimize treatment strategies for bone-predominant mRCC.

Univariate analysis showed that treatment with ICIs was associated with an increased risk of death compared to TKIs (hazard ratio = 1.96; P = 0.040). Objective response rates were higher in the TKI group (22.9% vs. 12.0%), although this difference was not statistically significant (P = 0.332). Conclusions: In this multicenter real-world analysis, first-line treatment with TKIs was associated with significantly improved OS compared to ICIs in patients with bone-predominant mRCC. These findings suggest that TKI-containing regimens may be the preferred front-line therapy for this patient subgroup. Prospective studies are warranted to validate these results and to optimize treatment strategies for bone-predominant mRCC.},

Immune correlates analysis of antibody responses against SARS-CoV-2 variants in the ENSEMBLE vaccine efficacy trial.
iScience, 28(11):113660.
In Latin American sites of the ENSEMBLE trial of the Ad26.COV2.S vaccine vs. placebo, binding antibodies and neutralizing antibodies measured 4 weeks post-vaccination (∼peak) against circulating lineages (Ancestral, Gamma, Lambda, Mu, Zeta) were assessed as a correlate of risk of, and correlate of protection against, lineage-specific COVID-19. Comparison of lineage-matched controlled vaccine efficacy (VE) curves showed similar relationships across lineages of lineage-specific antibody with VE against lineage-matched COVID-19, supporting a "variant-invariant correlate of protection model" that undergirds immunobridging inferences of efficacy against new variants based on variant-matched neutralizing antibody titers. Lambda departed from this model at undetectable/just-detectable titers: at ∼ peak Reference-specific titers of 2.7 arbitrary units (AU)/mL (just-detectable) and 30 AU/ml, VE against Ancestral COVID-19 was 53.0% (95% CI: 30.7%, 67.9%) and 84.5% (73.6%, 93.0%), respectively; at the same Lambda-specific titers, VE against Lambda COVID-19 was 12.3% (-54.1%, 50.3%) and 91.1% (68.9%, 98.0%). Additional research is needed for Omicron variants.

A multicenter dose-defining/expansion phase 1b study of first-line regorafenib plus pembrolizumab in patients with advanced hepatocellular carcinoma.
Hepatology (Baltimore, Md.) pii:01515467-990000000-01466 [Epub ahead of print].
BACKGROUND AND AIMS: Combinations including an immune checkpoint inhibitor are preferred first-line treatments for advanced HCC. We investigated the safety of regorafenib plus pembrolizumab as first-line systemic therapy for advanced HCC.
APPROACH AND RESULTS: This was a dose-defining/expansion phase 1b study in adults with advanced HCC without prior systemic treatment. Patients received regorafenib 80 or 120 mg/day for 3 weeks plus pembrolizumab 200 mg every 3 weeks in 4-week cycles (rego-80/pembro or rego-120/pembro): rego-80/pembro in the dose-defining phase; rego-80/pembro or rego-120/pembro in 2 dose-expansion cohorts. The primary objective was to assess safety; antitumor activity was a secondary objective. The MTD of regorafenib was 120 mg/day plus pembrolizumab; 4/19 patients receiving rego-120/pembro experienced dose-limiting toxicities [grade 3 increased AST with grade 1/2 increased bilirubin (n=2), and grade 3 rash (n=2)]. The most common treatment-emergent adverse events (TEAEs) in the overall safety cohort (n=57) were diarrhea (53%) and fatigue (51%). The most common grade ≥3 TEAEs were increased AST (18%) and hypertension (16%). Dose modifications due to study drug-related adverse events were less frequent with rego-80/pembro than with rego-120/pembro. The objective response rate (ORR) in 54 response-evaluable patients was 31% and the disease control rate (DCR) was 89%. Exploratory analyses suggested an association between lower angiogenesis and transforming growth factor-β signaling before treatment and response.
CONCLUSIONS: Treatment with rego/pembro is feasible in patients with advanced HCC with a manageable safety profile. ORR and DCR are promising and consistent with other immunotherapy combinations in this setting.

National cancer plans and primary care a systematic analysis comparing Latin American and non-Latin American countries.
Journal of cancer policy, 46:100659.
BACKGROUND: Cancer is a growing global health issue, particularly in middle- and high-income countries. National Cancer Control Plans (NCCPs) have emerged as a strategic response to reduce this burden. Primary care plays a crucial role across the cancer care continuum, yet its systematic inclusion in NCCPs remains unclear-especially in countries facing significant epidemiological challenges.
METHODS: This study employed a systematic qualitative design based on document analysis. Using the READ (Ready material, Extract data, Analyze, Distil) model, we examined the integration of primary care policies and practices in eight NCCPs: four from non-Latin American high-income countries (NLAHIc-Australia, Canada, the United States, and the United Kingdom) and four from Latin American middle-income countries (LATAMc-Argentina, Colombia, Chile, and Mexico). Covidence software facilitated the systematic text review, and a set of evidence-based key performance indicators (KPIs) was developed to guide the analysis.
RESULTS: Primary care integration varied across countries. LATAMc NCCPs showed greater inclusion of primary care than NLAHIc. Health promotion strategies were more consistently present in NLAHIc, while LATAMc better integrated primary prevention into primary care. However, only 50 % of KPIs for secondary prevention and 15 % for survivorship care were included in LATAMc. Palliative care was more consistently integrated in LATAMc (75 %) than in NLAHIc (33 %). Policy Summary This is the first study to benchmark NCCPs from Latin American and high-income countries using evidence-based KPIs to assess primary care involvement in cancer control. Findings highlight an urgent need to strengthen primary care integration. LATAMc should improve secondary prevention and survivorship care, while NLAHIc need to better incorporate primary prevention and palliative care into their NCCPs.

Access to Allogeneic Cell Transplantation Based on Donor Search Prognosis: BMT CTN 1702 Trial.
Transplantation and cellular therapy, 32(3):346-357.
Patients requiring allogeneic hematopoietic cell transplantation (HCT) have variable likelihoods of identifying an 8/8 HLA-matched unrelated donor (MUD). A Search Prognosis calculator can estimate the likelihood. This study (NCT#03904134; https://clinicaltrials.gov/study) evaluates if using a Search Prognosis algorithm results in similar incidence of transplant between patients Very Likely (>90%) versus Very Unlikely (<10%) to have a MUD. An additional objective included understanding barriers resulting in a delay or cancellation of a patient transplant. The national multicenter Blood and Marrow Transplant Clinical Trial Network (BMT CTN) 1702 interventional trial utilized Search Prognosis-based biologic assignment to guide donor selection. HCT eligible patients at participating transplant centers were invited to enroll. Patients assigned to the Very Likely arm were to proceed with MUD, while Very Unlikely were to utilize alternative donors. A third stratum, Less Likely (∼25%), were observed under standard center practices, but were not part of the primary objective. We report here the cumulative incidence of HCT by Search Prognosis group and barriers to HCT. Evaluable patients included 1751 of which 413 (24%) were from racial/ethnic minorities. Seach Prognosis was 958 (55%) Very Likely, 517 (30%) Less Likely, and 276 (16%) Very Unlikely. About 1171 (67%) received HCT, 384 (22%) died without HCT, and 196 (11%) remained alive without HCT. Among the 1234 patients (Very Likely versus Very Unlikely), the adjusted cumulative incidence (95% CI) of HCT at 6 months was 59.8% (56.7 to 62.8) in Very Likely versus 52.3% (46.1 to 58.5) in Very Unlikely (P = .113). Median time to HCT were similar in all Seach Prognosis groups. The predominant barriers resulting in a delay or cancellation of transplant were due to poor patient health (59%). Around 9% of delays and cancellations were attributed to excellent patient disease response, with only 14% of delays and 2% of cancellations due to donor reasons. A prospective Search Prognosis-based algorithm can be effectively implemented in a national multicenter clinical trial, with donor related barriers to transplant representing a small proportion of cases. This approach resulted in rapid alternative donor identification and no statistical difference in rates of HCT in patients Very Likely and Very Unlikely to find a MUD.

Second malignancies among older patients with classical myeloproliferative neoplasms treated with ruxolitinib.
Blood neoplasia, 2(4):100159.
Polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF) are classical Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) associated with an increased risk of development of second primary malignancies (SMs). The reasons for solid and lymphoid SMs are unclear, but a therapy-related effect has been invoked. Although an increased risk of nonmelanoma skin cancers is associated with the use of ruxolitinib (RUX), its influence on the development of other forms of SMs remains controversial. We conducted a retrospective cohort analysis to assess associations between RUX and SMs among older patients diagnosed with MPN from 2012 to 2019 in the Surveillance, Epidemiology, and End Results-Medicare-linked database. We identified 6043 patients (2396 with PV, 2944 with ET, 703 with MF) with a median age of 76 years (interquartile range [IQR], 71-82). After a median follow-up of 3.66 (IQR, 2.25-5.17) and 3.02 years (IQR, 1.84-4.75) for 513 RUX users and 5530 nonusers, respectively, 469 patients developed an SM: 383 solid and 86 lymphoid. In the multivariable proportional subdistribution hazard regression model with death as a competing risk, the risk of developing any SM did not differ by RUX use status (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.65-1.42; P = .84) or by proportion of days covered by RUX (every 10% increase; HR, 1.00; 95% CI, 0.96-1.05; P = .95). RUX exposure did not affect the risk of solid SM (HR, 0.77; 95% CI, 0.48-1.23; P = .27) or lymphoid SM (HR, 1.73; 95% CI, 0.79-3.80; P = .17). Our results suggest that RUX use does not increase the risk of SM in older patients with MPN.

Longitudinal transitions in sedentary behavior and physical activity in relation to all-cause and cause-specific mortality among postmenopausal women.
GeroScience [Epub ahead of print].
To evaluate longitudinal transitions in sedentary behavior and physical activity for the associations with all-cause and cause-specific mortality (i.e., cardiovascular disease [CVD], cancer, respiratory, and Alzheimer's disease/dementia mortality) among postmenopausal women. This prospective cohort study included 58,168 multiethnic US postmenopausal women from the Women's Health Initiative Observational Study, who had self-reported data on various sedentary behaviors and recreational physical activity at baseline (Y0: 1993-1998; age range: 50-79 years) and after 6 years (Y6). According to sedentary time (≥ 8 h/day or not) or physical activity (≥ 8.5 MET-h/week or not) at Y0 and Y6 assessments, participants were grouped by transition in sedentary behavior (consistently non-sedentary, sedentary to non-sedentary, non-sedentary to sedentary, and consistently sedentary) or physical activity levels (consistently low, high to low, low to high, and consistently high). Over a median follow-up of 15.0 years (from Y6 to March 2019), 17,354 all-cause deaths occurred, ranging from 1336 respiratory to 5111 CVD deaths. Compared to the consistently non-sedentary group, the two groups with unfavorable transitions in sedentary behavior (i.e., from non-sedentary to sedentary or being consistently sedentary) both had a higher risk of all-cause mortality and mortality from CVD, cancer, and respiratory disease. Conversely, the two groups with favorable transitions in physical activity (i.e., transitioning to or maintaining high activity), as compared with the consistently-low activity group, both had a lower risk mortality from all causes and several specific causes. Significant interactions were observed between transitions in sedentary behavior and physical activity on the risk of all-cause and CVD mortality (P-interaction < 0.01). Specifically, unfavorable sedentary transitions were associated with an elevated risk only among women with unfavorable transitions in physical activity. Among US postmenopausal women, maintaining or transiting to a sedentary lifestyle over 6 years was associated with a higher risk of mortality, predominantly among those not achieving regular physical activity over the years.

abstract = {To evaluate longitudinal transitions in sedentary behavior and physical activity for the associations with all-cause and cause-specific mortality (i.e., cardiovascular disease [CVD], cancer, respiratory, and Alzheimer's disease/dementia mortality) among postmenopausal women. This prospective cohort study included 58,168 multiethnic US postmenopausal women from the Women's Health Initiative Observational Study, who had self-reported data on various sedentary behaviors and recreational physical activity at baseline (Y0: 1993-1998; age range: 50-79 years) and after 6 years (Y6). According to sedentary time (≥ 8 h/day or not) or physical activity (≥ 8.5 MET-h/week or not) at Y0 and Y6 assessments, participants were grouped by transition in sedentary behavior (consistently non-sedentary, sedentary to non-sedentary, non-sedentary to sedentary, and consistently sedentary) or physical activity levels (consistently low, high to low, low to high, and consistently high). Over a median follow-up of 15.0 years (from Y6 to March 2019), 17,354 all-cause deaths occurred, ranging from 1336 respiratory to 5111 CVD deaths. Compared to the consistently non-sedentary group, the two groups with unfavorable transitions in sedentary behavior (i.e., from non-sedentary to sedentary or being consistently sedentary) both had a higher risk of all-cause mortality and mortality from CVD, cancer, and respiratory disease. Conversely, the two groups with favorable transitions in physical activity (i.e., transitioning to or maintaining high activity), as compared with the consistently-low activity group, both had a lower risk mortality from all causes and several specific causes. Significant interactions were observed between transitions in sedentary behavior and physical activity on the risk of all-cause and CVD mortality (P-interaction < 0.01). Specifically, unfavorable sedentary transitions were associated with an elevated risk only among women with unfavorable transitions in physical activity. Among US postmenopausal women, maintaining or transiting to a sedentary lifestyle over 6 years was associated with a higher risk of mortality, predominantly among those not achieving regular physical activity over the years.},

Operations and Impact of a Specialty-Specific National Incident Learning System: Ten Years of Radiation Oncology Incident Learning System (RO-ILS).
International journal of radiation oncology, biology, physics, 124(2):265-277.
Incident learning is recognized by national and international organizations as a key component of maintaining safety and quality in health care. In 2014, RO-ILS: Radiation Oncology Incident Learning System was launched by the American Society for Radiation Oncology and the American Association of Physicists in Medicine with the goal of facilitating safer and higher-quality care in radiation oncology. This review discusses the structure of the RO-ILS program, its foundations and operations, as well as outcomes in terms of engagement and learning opportunities. RO-ILS operates under the auspices and protection of patient safety organization in the United States. As of the end of 2024, 781 facilities have enrolled in the program, representing a mixture of United States practice settings (private practice, community/academic, free-standing/hospital-based, and small/large). A cumulative 41,516 events have been reported to the patient safety organization, the largest volume of events compared to other national and international aggregated incident learning systems in radiation oncology. A minority of events (24%) are incidents, that is, events that actually reached a patient regardless of harm. Approximately 10% of events were rated as potentially severe or critical. A key feature of the RO-ILS program is reports and other releases aimed at education and quality improvement. Over 100 releases have been issued, including case studies, great catches, safety notices, and themed reports, as well as industry webinars and user meetings. While there is evidence of success and engagement in the RO-ILS program, current and future challenges include the quantity and quality of reported data, the ability to effectively extract information, further engagement of key stakeholders, and program sustainability. These must be addressed for RO-ILS to continue to fulfill the mission of supporting safer and higher-quality care in radiation oncology.

Integrating Pathogenic Variants, Polygenic Risk Score, and Family History for Prostate Cancer Risk Estimation in Men of African Ancestry.
European urology [Epub ahead of print].
BACKGROUND AND OBJECTIVE: The impact of germline pathogenic variants (PVs) in cancer predisposition genes on risk of prostate cancer (PCa) remains understudied in large populations of African ancestry. This study aims to characterize the range of genetic risk of PCa and aggressive disease phenotypes in men of African ancestry.
METHODS: We analyzed 7176 PCa cases and 4873 controls from seven countries across North America and Africa to assess the association between PVs in 37 cancer predisposition genes and the risk of overall, aggressive, and metastatic PCa. Genes significantly associated with PCa risk were used to estimate lifetime absolute risk based on family history, polygenic risk score (PRS), and PV carrier status.
KEY FINDINGS AND LIMITATIONS: PVs in ATM, BRCA2, CHEK2, HOXB13, and PALB2 were presented in 4% of aggressive/metastatic PCa cases and were significantly associated with an increased risk of aggressive PCa (odds ratio 2.18-5.96, p < 0.05). Lifetime absolute risk varied widely depending on PV carrier status, PRS, and family history, ranging from 3.0% to 74% for overall PCa, 0.6% to 41% for aggressive PCa, and 0.2% to 37% for metastatic PCa. PV carriers with a positive family history and a PRS in the 90th percentile had seven, 18, and 34 times the risks of overall, aggressive, and metastatic PCa, respectively, compared with average-risk individuals. Oversampling of aggressive cases may limit the generalizability of these findings to screening populations.
Integration of PV status, PRS, and family history enables more refined PCa risk estimates. The wide range of PCa risk observed among men of African ancestry in our study supports future prospective studies in the development of risk-stratified cancer screening programs to identify high-risk individuals who may benefit from screening at an earlier age.

T-cell Subset Features and Distributions Evolve across the Colorectal Precancer-Cancer Spectrum.
Cancer immunology research, 14(1):46-59.
The immune microenvironment is a crucial component of colorectal carcinoma that has been well characterized, but much less is known about the immune microenvironment of colorectal carcinoma precursors. We hypothesized that T-cell infiltrates might differ across the colorectal neoplastic spectrum. We leveraged the prospective cohort incident-tumor biobank method, which provided formalin-fixed, paraffin-embedded tumor tissue specimens (N = 1,825) from 790 colorectal carcinoma precursors (including hyperplastic polyps, sessile serrated adenomas, traditional serrated adenomas, tubular adenomas, tubulovillous adenomas, and villous adenomas) and 1,035 colorectal carcinomas. We performed an in situ multispectral immunofluorescence assay for CD3, CD4, CD8, FOXP3 (negative, low, or high expression), PTPRC (CD45RO and CD45RA), MKI67 (Ki-67), and KRT (keratin) combined with supervised machine learning. CD3+CD4+ cells were more abundant than CD3+CD8+ cells in most precursors. In conventional adenomas, greater villous component correlated with fewer intraepithelial CD3+CD8+ cells. Serrated lesions, including hyperplastic polyps and sessile serrated lesions, exhibited higher densities of intraepithelial CD3+CD8+ cells compared with other precursors and carcinomas. Age strata of patients with precursors (including early-onset precursors) were not associated with differential T-cell infiltration patterns. Compared with invasive colorectal carcinoma, precursors generally showed higher densities of CD3+CD4+ cells and CD3+CD8+ cells with phenotypes of naive (CD45RA+CD45RO-), memory (CD45RA-CD45RO+), and regulatory (FOXP3+Low and FOXP3+High) in intraepithelial and lamina propria/stromal regions. In conclusion, T-cell infiltration patterns vary across different histopathologic types of the colorectal neoplastic spectrum from precursors to invasive carcinomas. Our findings shed light on how the tumor-immune microenvironment evolves during precursor development and progression to colorectal carcinoma.

Behavior of prediction performance metrics with rare events.
Journal of clinical epidemiology, 189:112046.
OBJECTIVE: Area under the receiver operating characteristic curve (AUC) is commonly reported alongside prediction models for binary outcomes. Recent articles have raised concerns that AUC might be a misleading measure of prediction performance in the rare event setting. This setting is common since many events of clinical importance are rare. We aimed to determine whether the bias and variance of AUC are driven by the number of events or the event rate. We also investigated the behavior of other commonly used measures of prediction performance, including positive predictive value, accuracy, sensitivity, and specificity.
STUDY DESIGN AND SETTING: We conducted a simulation study to determine when or whether AUC is unstable in the rare event setting by varying the size of datasets used to train and evaluate prediction models. This plasmode simulation study was based on data from the Mental Health Research Network; the data contained 149 predictors and the outcome of interest, suicide attempt, which had event rate 0.92% in the original dataset.
RESULTS: Our results indicate that poor AUC behavior-as measured by empirical bias, variability of cross-validated AUC estimates, and empirical coverage of confidence intervals-is driven by the number of events in a rare-event setting, not event rate. Performance of sensitivity is driven by the number of events, while that of specificity is driven by the number of nonevents. Other measures, including positive predictive value and accuracy, depend on the event rate even in large samples.
CONCLUSION: AUC is reliable in the rare event setting provided that the total number of events is moderately large; in our simulations, we observed near zero bias with 1000 events.
PLAIN LANGUAGE SUMMARY: Predicting self-harm or suicidal behavior is medically important for guiding clinicians in providing care to patients. Several research teams have developed and evaluated suicide risk prediction models based on health records data. Part of evaluating these models is calculating area under the receiver operating characteristic curve (AUC) and other prediction performance metrics. Self-harm and suicide are rare events. Recent research has raised concerns with using AUC in rare-event settings. We aimed to determine whether having a sufficiently large dataset could remove these concerns. In our experiments, we found that AUC can be used without concern in settings with 1000 events or more. Thus, AUC is a valid measure of suicide risk prediction model performance in many large healthcare databases.

Pulse Consumption and Metabolic Syndrome: Findings from the Hispanic Community Health Study/Study of Latinos.
Nutrients, 17(21):.
Background/Objectives: Metabolic syndrome affects half of middle-aged (ages 45-64) Hispanic or Latino (Latino) adults. Pulses, fiber-rich plant proteins common in Latino diets (e.g., dry beans and lentils), may mitigate metabolic syndrome. We evaluated the association between pulse intake and metabolic syndrome. Methods: We analyzed data from 6,958 adults aged ≥ 50 in the Hispanic Community Health Study/Study of Latinos (2008-2011) Visit 1. Pulse intake was assessed using two 24 h dietary recalls and categorized into no, low (<1/2 cup), moderate (≥1/2 to 3/4 cup), and high pulse (>3/4 cup) daily intake groups. Metabolic syndrome was defined by criteria including blood pressure ≥130/85 mmHg or medication use, triglycerides ≥150 mg/dL or medication use, high-density lipoprotein cholesterol (men <40 mg/dL and women <50 mg/dL), and waist circumference (men ≥102 cm and women ≥88 cm). We used multivariate logistic regression models with predicted probability proportions to assess the association adjusted for sociodemographic factors, acculturation, diet quality, energy intake, and physical activity. Results: Of the 6,958 participants, 53.1% had metabolic syndrome and 53.4% had a moderate or high pulse intake. Pulse intake varied, where 19.4% had a high intake, 33.9% had a moderate intake, 12.5% had a low intake, and 34.2% had no intake. Moderate (predicted marginal = 0.52, 95% confidence interval [CI] = 0.49, 0.55) and high (predicted marginal = 0.49, 95%CI = 0.45, 0.53) intakes were associated with a lower prevalence of metabolic syndrome. Conclusions: Among Latino adults ≥50 years old, a moderate or high pulse intake was associated with a lower prevalence of metabolic syndrome. Increasing the pulse intake in the population may be linked to reduced metabolic syndrome.

We used multivariate logistic regression models with predicted probability proportions to assess the association adjusted for sociodemographic factors, acculturation, diet quality, energy intake, and physical activity. Results: Of the 6,958 participants, 53.1% had metabolic syndrome and 53.4% had a moderate or high pulse intake. Pulse intake varied, where 19.4% had a high intake, 33.9% had a moderate intake, 12.5% had a low intake, and 34.2% had no intake. Moderate (predicted marginal = 0.52, 95% confidence interval [CI] = 0.49, 0.55) and high (predicted marginal = 0.49, 95%CI = 0.45, 0.53) intakes were associated with a lower prevalence of metabolic syndrome. Conclusions: Among Latino adults ≥50 years old, a moderate or high pulse intake was associated with a lower prevalence of metabolic syndrome. Increasing the pulse intake in the population may be linked to reduced metabolic syndrome.},

CRS or ICANS Are Rare Beyond 2 Weeks After Lisocabtagene Maraleucel Infusion: Data From Clinical Trials and the Real-World Setting.
Transplantation and cellular therapy, 32(2):171.e1-171.e12.
Improved understanding of the timing of cytokine release syndrome (CRS) and immune effector cell-mediated neurotoxicity syndrome (ICANS)/neurological events (NE) after chimeric antigen receptor (CAR) T-cell therapy infusion can inform patient safety monitoring. To report CRS and ICANS/NE outcomes, including incidence, onset, and resolution, in patients treated with lisocabtagene maraleucel (liso-cel) in clinical trials and the real-world setting. This analysis included patients treated with liso-cel in 5 clinical trials across different B-cell non-Hodgkin lymphoma indications (n = 702) and in the real-world setting for large B-cell lymphoma, as captured in the Center for International Blood and Marrow Transplant Research (CIBMTR) Registry (n = 877). All outcomes are reported descriptively. Among 702 patients in clinical trials, 54% had any-grade CRS (grade ≥3 at onset, 1%), with 98% of events occurring ≤day 15 after infusion; median time to resolution was 5 days. Any-grade NEs occurred in 31% of patients (grade ≥3 at onset, 5%), with 88% of events occurring ≤day 15 after infusion; median time to resolution was 7 days. Among 877 patients in the real-world setting, 49% had any-grade CRS (maximum grade ≥3, 3%), with 97% of events occurring ≤day 15 after infusion; median time to resolution was 4 days. Any-grade ICANS occurred in 27% of patients (maximum grade ≥3, 10%). Of 150 patients with reported onset date, 95% had onset ≤day 15 after infusion; median time to resolution was 5.5 days. The vast majority of CRS or ICANS/NEs occurred ≤day 15 after liso-cel infusion. These results support the recently updated United States Food and Drug Administration monitoring requirements aimed to improve treatment access while maintaining patient safety.

Changes in Liver Disease Etiology Support a Lower Alpha-Fetoprotein Threshold for Hepatocellular Carcinoma Screening.
Gastroenterology, 170(3):606-618.
BACKGROUND & AIMS: Serum alpha-fetoprotein (AFP) is a key component of hepatocellular carcinoma (HCC) screening, but its test characteristics are uncertain as alcohol-associated liver disease (ALD) and metabolic dysfunction-associated steatotic liver disease (MASLD) rates increase.
METHODS: We evaluated AFP trends at HCC diagnosis and estimated its test performance for HCC screening in cirrhosis using Veterans Health Administration (VHA) and United Network for Organ Sharing data.
RESULTS: Among the 40,399 VHA patients diagnosed with HCC between 2001 and 2021, median AFP at HCC diagnosis declined over time and was highest in active-hepatitis C (HCV) (32.7 vs cured-HCV 8.3, ALD 9.0, MASLD 7.7 ng/mL). Among the 28,170 VHA patients with cirrhosis receiving care in 2019 (9.6% active-HCV, 43% cured-HCV, 24% ALD, 14% MASLD), 1,029 developed HCC in 2019. At AFP thresholds ≥20 and ≥10 ng/mL, the overall sensitivity/specificity for HCC screening was 31.7%/98.5% and 41.9%/94.1%, respectively. Lowering the AFP threshold to ≥10 ng/mL increased sensitivity with minimal reductions in specificity across all liver disease etiologies: active-HCV (sensitivity/specificity: 43.7% to 60.7%/92.6% to 83.0%), cured-HCV (32.5% to 41.5%/99.0% to 94.7%), ALD (22.8% to 32.3%/99.2% to 95.1%), and MASLD (21.7% to 29.9%/99.4% to 96.7%). Analysis of United Network for Organ Sharing (26,213 patients with HCC) resulted in similar increases in test sensitivity as the AFP threshold declined from ≥20 to ≥10 ng/mL (overall: 31.8% to 48.7%; active-HCV: 36.7% to 58.6%, cured-HCV: 21.4% to 36.4%, MASLD: 19.1% to 33.4%, and ALD: 15.9% to 27.1%).
CONCLUSIONS: For HCC screening in MASLD, ALD, and cured-HCV cirrhosis, reducing the AFP threshold to ≥10 ng/mL would substantially increase sensitivity while maintaining very high specificity.

Investigating the association between anthropometry and colorectal cancer survival: a two-sample Mendelian randomization analysis.
International journal of epidemiology, 54(6):.
BACKGROUND: Observational epidemiologic studies on the association of anthropometric traits and colorectal cancer (CRC) survival provide inconsistent results, and potential limitations prohibit the investigation of causality. We examined the associations between seven genetically predicted anthropometric traits [height, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist-hip circumference ratio, birth weight and body fat percentage] and CRC-specific mortality among CRC cases using two-sample Mendelian randomization (MR).
METHODS: Analyses were performed using 16 964 CRC cases, out of which 4010 died due to their disease, from the Genetics and Epidemiology of Colorectal Cancer Consortium and Colon Cancer Family Registry. We further conducted stratified analyses by anatomical site and stage. We applied the inverse variance weighted approach, and sensitivity analyses were conducted to assess the impact of potential violations of MR assumptions and adjust for collider bias.
RESULTS: One standard deviation (SD 13.4 cm) higher genetically predicted levels of WC were associated with worse CRC survival [hazard ratio (HR); 1.22, 95% confidence interval (CI); 1.02-1.47]. Positive associations were further observed for a SD higher genetically predicted BMI (SD; 4.8 kg/m2, HR; 1.5, 95% CI; 1.15-1.95) and HC (SD; 9.2 cm, HR; 1.32, 95% CI; 1.02-1.73) and CRC-specific mortality in cases of stages II/III. The latter associations were generally robust to sensitivity analyses. Positive but imprecisely estimated associations were found for most other anthropometric traits.
CONCLUSIONS: Despite the limitations of cancer survival research, our findings support that CRC cases should avoid obesity. Further research should inform the development of recommendations targeting overweight/obesity management during cancer surveillance.

Unbiased cell clustering analysis of vaccine-induced T cell responses in the Imbokodo HIV-1 vaccine trial.
EBioMedicine, 122:106017.
BACKGROUND: HIV-1 T cell responses are associated with viral control and may be protective in a prophylactic vaccination setting. Traditional methods for analysing these responses might be biased towards specific functionalities or epitopes. This study presents an unsupervised and unbiased clustering analysis workflow, using the Leiden algorithm followed by selection of antigen-specific clusters using MIMOSA positivity calls, for high-dimensional flow cytometry data to identify distinct T cell populations associated with protection in the HVTN 705/HPX2008/Imbokodo HIV-1 vaccine efficacy trial.
METHODS: Participants were vaccinated with Ad26.Mos4.HIV (M0, M3) and Ad26.Mos4.HIV + Clade C gp140 (M6, M12), and a validated 28-colour intracellular cytokine staining assay was performed on PBMC isolated at M7, M13 and M24 in a pilot immunogenicity (n = 60) and case-control cohort (n = 283). 28-colour phenotyping assays were also performed on PBMC from the case-control cohort (n = 334).
FINDINGS: Our clustering analysis workflow allowed identification of vaccine-induced subpopulations of both CD4+ and CD8+ T cells expressing combinations of the 28 markers. Durable HIV-1 antigen-specific CD4+ and CD8+ T cell responses were observed for up to 2 years, comprising mainly clusters of polyfunctional T cells expressing anti-viral cytokines and activation markers. Eight CD4+ and six CD8+ HIV-1 antigen-specific T cell clusters were induced by vaccination; only one CD4+ T cell cluster specific for Gag was mildly elevated in cases (acquiring HIV) compared to controls.
INTERPRETATION: Our study introduces an innovative analysis approach to identify vaccine-induced T cell subpopulations in vaccine trials. Comparison of T cell clusters between cases and controls holds promise for improving the efficacy of future HIV-1 vaccination strategies.
FUNDING: This work was funded by the National Institute of Allergy and Infectious Diseases (NIAID) and the Division of AIDS (DAIDS), both of the US National Institutes of Health (NIH) [NIAID grants to the HIV Vaccine Trials Network (HVTN) (Fred Hutchinson Cancer Center): UM1AI068618 (HVTN LC to M.J.M.) and UM1AI068635 (HVTN SDMC to P.B.G.)] and by Janssen Vaccines & Prevention B.V.

ESP Quick Facts
ESP Origins
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
ESP Support
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
ESP Rationale
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
ESP Goal
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
ESP Usage
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
ESP Content
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
ESP Help
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
ESP Plans
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
