Abstract Oncology Advanced Practice Providers (APPs), including Advanced Practice Registered Nurses, Physician Assistants, and Clinical Pharmacists (CPs), play a vital role in delivering high-quality, patient-centered cancer care across the United States. Despite their widespread presence in oncology practices, APPs remain underutilized in cancer clinical research, representing a missed opportunity to expand trial access and improve patient outcomes. Clinical trials are essential to advancing oncology care, yet participation remains critically low among adult patients. Given Oncology APPs’ and CPs’ central role in cancer care delivery, their meaningful engagement in oncology clinical trial research is imperative as the standard of oncology care. This position article, with contributions from 5 professional societies, presents solutions and resources to barriers limiting APPs’ and CPs’ involvement in cancer clinical research, including gaps in education, role expectations, limited protected time, restrictive policies, insufficient financial support, and underrecognition of contributions. Integrating APPs and CPs more fully into the clinical research enterprise is essential to improving trial access, patient outcomes, closing equity gaps, and accelerating innovation in oncology care.

Background and Aims: Liver transplantation has evolved from a treatment restricted to patients with end-stage liver disease to a therapeutic option for selected patients with primary and metastatic liver malignancies. This review explores the rapidly expanding field of transplant oncology, highlighting its role in hepatocellular carcinoma, colorectal liver metastasis, neuroendocrine liver metastasis, and intrahepatic and perihilar cholangiocarcinoma. Emphasis is placed on strategies to broaden eligibility, optimize donor organ use, and improve oncologic outcomes. Approach and Results: We synthesized current evidence from clinical series, registries, and experimental protocols to evaluate patient selection criteria, outcomes, and peri-transplant management. Key topics include downstaging approaches to meet transplant criteria, such as locoregional therapies and systemic regimens, and their prognostic implications. Advances in donor utilization have been analyzed for their capacity to expand the graft pool. In addition, the review addresses the integration of oncologic principles into immunosuppression regimens, balancing graft protection with cancer control. Collectively, the reported studies demonstrate improved survival and reduced recurrence when stringent selection and multimodal therapy were applied. Conclusions: Transplant oncology reshapes the therapeutic landscape of liver malignancies, with growing evidence supporting liver transplantation in carefully selected patients beyond traditional indications. Optimized downstaging, innovative donor strategies, and tailored immunosuppression are pivotal for safe expansion. Continued collaboration between the transplant and oncology disciplines, along with prospective trials, is essential to further define standardized protocols and solidify transplantation as a cornerstone of multidisciplinary cancer care.

ABSTRACT Background Immune checkpoint inhibitors (ICIs) have emerged as promising agents for the management of advanced HCC. By reducing tumour burden, ICIs may serve as a downstaging/bridging tool to improve transplant candidacy. The aim of this study was to assess the safety of patients receiving pre‐LT ICIs. Methods Multicenter, retrospective cohort study from January 2018 to December 2024, including 48 patients who received ICIs prior to LT (ICI cohort). A control cohort (non‐ICI cohort) was built (1:3) using propensity score matching including 144 patients who underwent LT for HCC without prior ICI. Results Within the ICI cohort ( N = 48) rejection occurred in 9 patients (18.8%), all biopsy‐proven, with a median onset of 31 days post‐LT (12.0–182.0). The median washout period was 60 days (13–96). Patients experiencing rejection had shorter washout periods ( p = 0.029). All rejection episodes were successfully managed; two were steroid‐resistant, one requiring re‐transplantation. There were no rejection‐related deaths. Of the 5 patients with HCC recurrence, 60% received ICI for < 90 days ( p = 0.027). Comparison between the ICI and non‐ICI cohort revealed no significant differences in rejection rates (18.8% vs. 19.4%, p = 0.916), graft failure, HCC recurrence, or overall mortality. Overall survival (OS) did not differ between ICI and non‐ICI patients ( p = 0.625) or between those with and without rejection ( p = 0.119). Rejection was not associated with increased mortality, with deaths primarily attributed to infection or HCC recurrence. Conclusion Our results demonstrate that rejection rates were similar in patients receiving ICIs pre‐LT and it can be safely managed.

Abstract Motivation: Epilepsy is a diverse group of neurological disorders affecting over 50 million people worldwide. While common epilepsy types are well studied, rare epilepsies—often severe and genetically complex—pose significant challenges in diagnosis, research, and treatment. Accurate and interoperable etiology and disease classifications are critical for improving data sharing, supporting clinical decision-making, and advancing rare disease research. Results: To enhance the accuracy of epilepsy-related disease concept representation within the Mondo Disease Ontology (Mondo), we conducted a series of expert-driven workshops in collaboration with the team from the Rare Disease Cures Accelerator-Data and Analytics Platform (RDCA-DAP). Specialists in epileptology, genetics, neurodevelopment, biomedical ontology, and patient community advocates systematically reviewed and revised the epilepsy hierarchy in Mondo, aligning it with the International League Against Epilepsy (ILAE) classification system. These updates include reclassification of epilepsy subtypes, including syndromes, age-related epilepsies, and developmental epileptic encephalopathies, resulting in a more granular, standardized, and clinically relevant structure. Mondo now offers an enhanced framework for integrating epilepsy data across resources, enabling improved interoperability and facilitating rare disease research and data curation, with continued efforts underway to further refine and expand this integration.

Abstract Background Cerebrospinal fluid (CSF) seed amplification assays (SAAs) for detecting α‐synuclein (αsyn) seeds have recently emerged as robust in vivo biomarkers of Lewy body pathology (LBP). However, CSF sampling is invasive, costly, and time‐consuming, limiting its widespread use. We aimed to develop and evaluate a neuropathologically‐validated two‐step workflow, leveraging smell function and CSF αsyn SAA to accurately determine postmortem LBP status. This approach could reduce the number of confirmatory lumbar punctures needed (Figure 1). Methods The study included 358 individuals from the Arizona Study of Aging and Neurodegenerative Disorders with antemortem smell testing, CSF αsyn SAA results, and postmortem neuropathological assessments of regional LBP burden. Step‐1 of the two‐step workflow involved a risk‐stratification model predicting postmortem cortical LBP‐positivity (LBP ctx , defined as at least mild pathology in any cortical region) using logistic regression models with University of Pennsylvania Smell Identification Test (UPSIT) scores (smell testing), age, and sex as predictors. In step‐2, confirmatory CSF αsyn SAA testing was applied only to participants identified as high‐risk in step‐1. Workflow performance ‐ accuracy, positive predictive value (PPV), negative predictive value (NPV), and reduction in CSF testing ‐ was evaluated in (i) the entire study cohort; (ii) patients with clinical parkinsonism; (iii) patients with an Alzheimer's disease (AD) clinical syndrome; and (iv) clinically unimpaired (CU) individuals. Results Participants had a mean age at death of 86.2±7.8 years, 42.6% were female, 35.2% had LBP ctx , and the average time between UPSIT and death was 3.2±2.3 years (Table 1). Using a 95% sensitivity cut‐off for the UPSIT‐based algorithm, the two‐step workflow achieved high accuracy in identifying LBP ctx (whole cohort=94%; clinical parkinsonism=95%; clinical AD=94%; CU=93%; Figure 2a), while reducing CSF testing (whole cohort=‐43%; clinical parkinsonism=‐23%; clinical AD=‐35%; and CU=‐80%; Figure 2d). PPVs ranged from 75‐96% and were highest in the clinical parkinsonism subgroup (96%) where LBP ctx + was highest (62.7%). NPVs ranged between 95‐98% and were highest in the clinical AD subgroup (98%) (Figure 2b‐c). The two‐step approach reached accuracies similar to using CSF tests in all participants. Conclusions Implementing a two‐step workflow in different clinical scenarios may reduce invasive testing with CSF, minimizing the burden for individuals and costs for healthcare providers.

ABSTRACT Background We recently published the first real‐world multicenter and multi‐institutional study of cisplatin, gemcitabine, and durvalumab in patients with advanced biliary tract cancer (BTC). Here we present an expanded patient cohort with an increased sample size and longer median follow‐up. Methods The study population included patients with advanced BTC, who received cisplatin/gemcitabine plus durvalumab at 55 centers across 12 countries in Europe, the United States, and Asia. The primary endpoints of the study were progression‐free survival (PFS) and overall survival (OS). Secondary endpoints were overall response rate (ORR) and safety. Results Overall, 1358 patients were enrolled. Median PFS was 7.6 months (95% CI: 7.2–8.1), and median OS was 15.6 months (95% CI: 14.8–16.5). ORR was 35.6%, and DCR was 82.7%. Any grade AEs occurred in 1213 patients (89.3%). Grade 3–4 AEs occurred in 597 patients (43.2%). The rate of immune‐related AEs (irAE) was 20.3%. Grade 3–4 irAE occurred in 3.0% of patients. At the multivariate analysis for OS, normal albumin level (HR 0.68, 95% CI 0.57–0.81, p < 0.0001), CEA levels within normal ranges (HR 0.68, 95% CI 0.57–0.82, p < 0.0001), NLR < 3 (HR 0.62, 95% CI 0.52–0.74, p < 0.0001), ECOG PS 0 (HR 0.51, 95% CI 0.42–0.61, p < 0.0001), and prior surgery (HR 0.80, 95% CI 0.65–0.99, p = 0.036) were positive prognostic factors. Conclusion The updated findings, derived from an expanded cohort, further support the adoption of durvalumab in combination with gemcitabine and cisplatin in routine clinical practice, reinforcing the efficacy and safety outcomes demonstrated in the phase III TOPAZ‐1 trial.

BACKGROUND: Although chronic obstructive pulmonary disease (COPD) and heart failure with preserved ejection fraction often coexist with overlapping clinical features, they are usually studied separately. The SPIROMICS HF (Subpopulations and Intermediate Outcome Measures in COPD and Heart Failure Study) is testing hypotheses that new computed tomography emphysema subtypes are associated with specific cardiovascular phenotypes (eg, cor pulmonale , cor pulmonale parvus ), common airway branch variants are associated with right heart dysfunction, and symptomatic tobacco-exposed persons with preserved spirometry have signs of increased left ventricular afterload. METHODS: SPIROMICS is a multicenter observational study of COPD with extensive pulmonary phenotyping of participants with ≥20 pack-years smoking and nonsmoking controls. COPD and COPD severity were defined by standard spirometric criteria and symptomatic tobacco-exposed persons with preserved spirometry by ≥20 pack-years, normal spirometry, and COPD Assessment Test score >10. SPIROMICS HF selected all participants in SPIROMICS visit 5 at major sites. Its comprehensive speckle-tracking echocardiography, which included physiological perturbations of leg raise and low-intensity exercise, was harmonized prospectively with the Multi-Ethnic Study of Atherosclerosis Early Heart Failure and HeartSHARE (Combining Omics, Deep Phenotyping, and Electronic Health Records for Heart Failure Subtypes and Treatment Targets) studies. The cardiopulmonary magnetic resonance imaging protocol with gadolinium administration included myocardial fibrosis sequences, pulmonary angiography, time-resolved 3-dimensional cine magnetic resonance imaging (4-dimensional flow) of venous return, and metronome-paced tachypnea to induce dynamic hyperinflation. Coronary artery calcium was assessed on computed tomography scans. The Kansas City Cardiomyopathy Questionnaire was administered. RESULTS: Of the final sample of 753 participants, 57% had COPD (15% mild, 27% moderate, and 15% severe), 18% had symptomatic tobacco-exposed persons with preserved spirometry, 16% were smoking controls, and 8% were nonsmoking controls. Reproducibility of the main measures from speckle-tracking echocardiography (intraclass correlation coefficient, 0.83–0.99), exercise echocardiography (intraclass correlation coefficient, 0.71–0.99) and magnetic resonance imaging (intraclass correlation coefficient, 0.57–0.99) were good-to-excellent, including in severe COPD. CONCLUSIONS: SPIROMICS HF aims to characterize and understand cardiopulmonary interactions in COPD and COPD-related phenotypes to inform targeted treatments for combined cardiopulmonary failure.

Despite efforts to improve donor heart allocation policies, geographic disparities, logistical challenges and patient criteria limit organ availability. However, recent surgical innovations offer potential solutions. These include partial heart transplantation and xenotransplantation. Partial heart transplantation is a new procedure with the potential to address several clinical challenges in treating congenital heart defects. Cardiac xenotransplantation involves the transplantation of genetically modified porcine hearts into humans, offering a potential solution to the shortage of donor organs. Although immunologic barriers and ethical concerns remain, ongoing research aims to mitigate the risks and optimize outcomes, providing hope for patients in need. These innovative surgical approaches offer promising avenues for addressing the critical shortage of donor hearts and with ongoing research, may hold the potential to revolutionize heart transplantation, and improve outcomes for patients facing terminal heart failure.

230 Background: The burden of symptoms and financial toxicity are well-documented adverse effects of cancer treatments. Recently, logistic toxicity has emerged, referring to the detrimental impact of logistical demands associated with cancer treatment on patient well-being. For non- English speaking patients, language barriers can affect their treatment experience, increasing logistic burdens. Methods: Between September 2024 and May 2025, semi-structured qualitative interviews were conducted with 21 low English proficiency (LEP)/non-English speaking adults with cancer. The interviews explored logistic challenges faced due to LEP and its impact on patients' cancer care experience. Transcripts were analyzed using an inductive thematic analysis approach. Results: Of the 39 identified eligible individuals, 26 provided consent, and 21 (81%) completed the interview. The most common primary language of the participants was Spanish (9, 43%), followed by Somali (3, 14%), Arabic and Korean (2, 9%), and Amharic, Mandarin, Hmong, Russian, and Vietnamese (1, 5%). Seven major themes emerged regarding the logistic burdens of cancer care: (1) communication challenges, (2) navigating healthcare systems, (3) emotional distress from diagnosis and communication barriers, (4) financial toxicity, (5) transportation challenges, (6) adverse treatment effects, and (7) concerns about the political climate and its impact on resources. Conclusions: The increase in non-English languages in the U.S. highlights the need to understand the unique challenges faced by these patients. This study identified logistic toxicity themes consistent with previous research, while also revealing unique challenges. Further research is necessary to explore strategies to mitigate logistic burdens among those with LEP.
