Evidence-based practice is critical to providing high-quality hospice and palliative nursing care. Professional organizations, such as the Hospice and Palliative Nurses Association (HPNA), play a critical role in shaping the future of the hospice and palliative nursing field by identifying gaps in the science and fostering collaborative research efforts to inform evidence-based practices. One such driver is the tri-annual HPNA Research Agenda, which outlines key research priorities in hospice and palliative nursing, ultimately aiming to accelerate translation of research into practice and practice improvements. In this article, 6 emerging research scholars in the field and present and former co-chairs of the HPNA Emerging Research Scholar Special Interest Group reflect on the experiences that led them to pursue research careers in hospice and palliative nursing. Through a process of collective self-assessment, these scholars articulated their shared progress toward addressing the research priorities outlined in the 2023–2026 HPNA Research Agenda as a means of generating insights to direct future research efforts in the field.

PURPOSE To compare patient-reported and clinical outcomes between radical cystectomy (RC) and bladder-sparing therapy (BST) in patients with recurrent high-grade non–muscle-invasive bladder cancer (NMIBC). PATIENTS AND METHODS This pragmatic, prospective observational cohort study was designed with patients, who selected and prioritized outcomes. Eligible adults were candidates for both RC or BST, had previous induction Bacillus Calmette-Guérin (BCG), and received their last treatment within 12 months. The primary outcome was the EORTC-QLQ-C30 physical function scale at 12 months. Secondary outcomes included other EORTC-QLQ-C30 scales, depression, anxiety, bladder cancer–specific quality of life (QOL), financial burden, and cancer-specific outcomes. Targeted maximum likelihood estimation (TMLE) was used to calculate average treatment effect (ATE) estimates between arms. Inverse probability weighted risk ratios (wRR) were calculated using quasi-Poisson regression. RESULTS Of 570 participants (mean age 71.4 years; 21% female), 371 selected BST and 199 selected RC. Physical function was significantly worse in the RC arm at 3 months; by 9 months, there was no difference between arms, and at 12 months, physical function did not differ (ATE, 0.9; 95% CI, –0.6 to 2.4; P = .22). RC was associated with better emotional function, generic health-related QOL, and financial burden, and lower depression and anxiety, while BST was associated with better bowel and sexual health. Cancer-specific survival was 99% for BST versus 96% for RC (wRR, 0.99; 95% CI, 0.97 to 1.01). RC was associated with a higher risk of adverse events and serious adverse events, including a 90-day mortality rate of 2.5%. CONCLUSION Most patient-prioritized outcomes were similar or better among participants who chose RC compared with BST. These findings support the continued role of RC in managing recurrent high-grade NMIBC.

Background: Clozapine is the preferred medication for treatment-resistant schizophrenia with therapeutic drug monitoring (TDM) suggested to mediate its safe and effective use. However, clozapine TDM is not a ubiquitous element of care in clinical practice. Understanding the current state of clinicians' perceptions of and barriers to clozapine TDM is a crucial step in improving its use. Methods: A survey related to the use, perceptions, and barriers of clozapine TDM was distributed across multiple national organizations in the United States, representing several disciplines. Results: Most of the 190 respondents were consultants or attending physicians (42.5%) or pharmacists (52.3%). Nearly 80% of respondents had ordered clozapine level measurements in the year before completing the survey but identified slow turnaround time (TaT) as an important barrier; 73.5% of respondents noted that level measurements were performed at an offsite laboratory. Although 86.8% agreed that clozapine levels should be checked once an initial target dose was reached, less than half would subsequently order clozapine level measurements routinely, unless clinical factors such as nonadherence (96.5% agreement), new interaction (94.5% agreement), or change in smoking status (94.5% agreement) occurred. More pharmacists than prescribers indicated confidence in interpreting and clinically applying clozapine TDM results (84.6% versus 70.1%, P = 0.024), with a similar finding between the groups regarding faster clozapine TDM TaT, resulting in improved patient safety (89.0% versus 68.7% agreement, P = 0.003). In addition, more pharmacists would also conduct clozapine TDM in the setting of an acute inflammatory or infectious process (84.9% versus 61.2%, P = 0.002). Conclusions: These data provide insights into clozapine TDM perception, availability, TaT, and barriers. Further research is required to assess whether a faster TaT and more frequent clozapine TDM positively influence patient outcomes from a safety and effectiveness perspective.

Background. As cancer therapeutics improve, more liver transplant (LT) candidates will have a history of prior to transplant malignancy (PTM), an established risk for cancer posttransplant. Methods. This study provides granular analysis (with focus on nonliver PTM) of posttransplant cancer risk relating to PTM in 1105 consecutive adult LT recipients (2009–2019, N = 542 with PTM). Results. PTM prevalence increased from 37.8% to 63.2% during this timeframe. Post-LT survival was lower (10 y: 61.2% versus 75.1%; P < 0.001) with higher cancer-related mortality (17.6% versus 2.2%; P < 0.001) in patients with any PTM. The higher cumulative incidence of cancer post-LT associated with PTM (59.7% versus 37.6%; P < 0.001) was not attributable to de novo cancer (38.5% versus 37.7%; P = 0.21) but to recurrence. Cancer recurrence rate (10 y) was lowest in nonliver/nonskin (“other”) PTM (10.6%) with mortality rates from recurrence of only 4% in this cohort. De novo cancers may present at more advanced stage in patients with PTM and lung cancer the most common nonskin de novo malignancy (PTM 21%, no PTM 7%). Family history of cancer was an independent predictor for de novo cancer. Conclusions. PTM associated post-LT cancer outcomes are dominated by skin and liver cancer recurrence and not recurrence of “other” cancers or de novo cancer. This data supports the guidance proposals for cautious liberalization of “other” cancer remission requirements before transplantation. As post-LT cancer is highly prevalent regardless of PTM status, adherence to posttransplant cancer screening and surveillance is critical to identify early cancer after transplant.

Abstract Wiskott-Aldrich syndrome (WAS), an X-linked disorder characterized by immunodeficiency, thrombocytopenia, autoimmunity, and malignancy, can be effectively treated with allogeneic hematopoietic cell transplantation (HCT). Older age at HCT and mismatched donors are known to affect overall survival (OS). However, the influence of specific clinical manifestations or WAS variant class on OS and factors associated with event-free survival (EFS) remain incompletely defined. We analyzed outcomes of 308 patients with WAS who underwent HCT at 37 institutions of the Primary Immune Deficiency Treatment Consortium from 1990 to 2018. With a median follow-up of 5.3 years, the 5-year OS and EFS were 87.2% and 79.7%, respectively. Age ≥5 years, donor type, and a pre-HCT history of severe infection had a negative impact on OS and EFS, whereas pre-HCT autoimmunity had no impact. Reduced-intensity regimens were associated with lower T-cell and myeloid donor chimerism, particularly when non–busulfan-based regimens were used. Low myeloid donor chimerism was associated with lower platelet counts. Mixed chimerism was not consistently associated with post-HCT autoimmunity. Patients with class I (exon 1-2 missense and intron 5 hot spot variants) and class II variants (all others) had similar pre-HCT clinical symptom severity and no difference in OS, EFS, or platelet recovery post-HCT. In conclusion, our study showed excellent long-term OS and EFS after HCT for WAS, highlighting the importance of early HCT, before the development of severe infections. We confirmed that HCT using busulfan-based conditioning was associated with improved donor chimerism and platelet recovery. This trial was registered at www.clinicaltrials.gov as NCT02064933.

Abstract Introduction Obecabtagene autoleucel (obe-cel) and brexucabtagene autoleucel (brexu-cel) are CD19 targeted chimeric antigen receptor T cell (CAR-T) therapies, approved for the treatment of adults with relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (ALL). Mechanistic differences between obe-cel and brexu-cel including differing costimulatory domains (4-1BB vs. CD28), CD19 binding domains (intermediate vs. high affinity) and split dose (Days 1 and 10) vs. single infusion may impact in-vivo cellular kinetics that translate into variant clinical outcomes. In pivotal trials, obe-cel resulted in lower rates of severe cytokine release syndrome (CRS) and immune effector cell associated neurotoxicity syndrome (ICANS) compared to brexu-cel with comparable efficacy (Roddie et al., NEJM 2025; Shah et al., Lancet 2021). Real-world utilization and outcomes with obe-cel are unknown given the relatively recent approval. Methods The ROCCA database, comprising real world data from patients (pts) with r/r ALL treated at 40 North American institutions was utilized in this analysis. Pts with r/r ALL were eligible if they were apheresed for obe-cel since its approval (11/8/2024) or brexu-cel over a comparable period (since 8/1/24) and had at least 30 days of follow up. Data cut off was 7/15/2025. CRS/ICANS were graded per ASTCT criteria. Measurable residual disease (MRD) was assessed by flow cytometry and/or next generation sequencing per institutional standards. Results 38 pts have undergone apheresis for obe-cel (36 infused, all received both infusions) and 54 (53 infused) for brexu-cel over the study period. Pts in the obe-cel and brexu-cel cohorts had the following baseline characteristics: median age, 47 vs. 39 years; ECOG 2+, 15% vs. 26%; Ph+ disease, 24% vs 13%; KMT2Ar, 0 vs. 4%; TP53m, 11% vs 11%, and hypodiploid karyotype, 5% vs 6%. The following prior treatment patterns were observed: median lines of therapy before CAR-T 3 vs. 3; prior SCT 24% vs. 30%, prior blinatumomab 68% vs. 46%, prior inotuzumab 45% vs. 30%. At apheresis, active disease (&gt;5% bone marrow blasts) was present in 47% vs. 55% of obe-cel and brexu-cel pts, respectively; the remainder were in CR (with 18% vs. 22% in MRD- CR, respectively). Among obe-cel (n= 35 [92% of cohort]) and brexu-cel (21 [38% of cohort] pts with disease re-assessment prior to lymphodepletion (LD), 31% vs. 43% had active BM disease, respectively; few pts (24% vs. 17%) had &gt;20% marrow disease burden prior to LD. CAR-mediated toxicity differed significantly between the cohorts. CRS occurred in 56% of obe-cel pts compared to 94% of brexu-cel pts (p &lt; 0.0001). There were no Gr3+ CRS events among the obe-cel pts; 3 (6%) brexu-cel pts had Gr3+ CRS (p = 0.27). ICANS occurred in 17% of obe-cel pts vs. 51% of brexu-cel pts (p = 0.001). Gr3+ ICANS occurred in 6% of obe-cel vs. 32% of brexu-cel pts (p = 0.0027). Among the obe-cel pts, CRS occurred in 31% after the first infusion and 46% after the second; ICANS occurred in 3% after the first infusion and 15% after the second. Prolonged Gr4 neutropenia (ANC &lt; 500 cells/uL beyond day 30 from infusion) occurred in 24% of obe-cel vs. 28% of brexu-cel pts (p = 0.73). Deaths within the first 28 days of infusion occurred in 0 obe-cel pts and 4 brexu-cel pts (2 of infection, 1 of infection/brain bleed, and 1 of liver failure in the setting of Gr4 CRS and HLH). Response rates were high and did not significantly differ between cohorts (p = 0.85). Among the 31 obe-cel pts with available response data, 25 (81%) achieved an MRD- CR/CRi, 3 (10%) had an MRD+ CR/CRi, 2 (6%) had a CR/CRi with unknown MRD, and 1 (3%) did not respond. Among 41 brexu-cel pts with available response data, 33 (80%) had an MRD- CR/CRi, 4 (10%) an MRD+ CR/CRi, and 4 (10%) CR/CRi with unknown MRD. Conclusion Pts selected for obe-cel apheresis were similar to those for brexu-cel over the study period (noting that not all centers had access to obe-cel during this time). Similar to clinical trial results, obe-cel was associated with lower rates of CRS/ICANS. Rates of MRD-negative CR were high and did not differ between cohorts. A larger sample and longer follow up are required for further analyses; we anticipate a cohort of ~75 obe-cel treated pts by the annual meeting and will provide updated data.

Abstract Background: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL), accounting for approximately 30% of all NHL cases. DLBCL diagnosis relies on histologic examination, immunophenotyping, molecular and fluorescence in situ hybridization (FISH) analysis to differentiate it from similar NHL subtypes with overlapping morphological features, including more high-grade lymphomas like double-hit lymphoma. Because FISH is performed in a panel of single- or dual-target test format and analyzed through microscopy and manual image analysis, assessment of multiple target biomarkers can be cumbersome and expensive. As additional biomarkers for diagnosis, subtyping, prognosis, and therapeutic decision-making become available, target panels will become larger, posing additional challenges to clinical laboratories. Patients and Methods In this study, Hi-C sequencing of FFPE samples was performed to identify all genomic rearrangements by a single sequencing analysis for an unselected DLBCL case series of 159 patients, and the results were compared to FISH for the detection of clinically important variants. Results Hi-C sequencing showed superior performance compared to FISH: standard FISH for DLBCL includes testing for MYC, BCL2, and BCL6. Between FISH and Hi-C, these biomarkers were detected 105 times, of which, FISH detected 80/105 (76%) and Hi-C detected 102/105 (97%). The cohort included 4 double-hit lymphomas by FISH but Hi-C sequencing detected five. Besides DLBCL diagnostic biomarkers (MYC, BCL2, BCL6), many additional biomarkers were detected by Hi-C sequencing including variants not tested by FISH because the clinical suspicion was ambiguous and the relevant FISH probes were not used, and those not tested because the biomarkers were not thought to be common and, hence, left out of the FISH panel. In total, Hi-C sequencing detected additional biomarkers in 42 (26%) cases, including (1) variants targeted by FISH (i.e. MYC, BCL2, BCL6) but negative, (2) classification biomarkers for other lymphomas (CCND1, MALT, IRF4), and (3) those not tested because the biomarkers are not common and not included in the FISH panel. These additional biomarkers were supportive of suspected diagnosis of DLBCL versus double-hit lymphoma (24 cases), prompted reconsideration of a different diagnosis that may have led to different treatments (6 cases, e.g. mantle cell lymphoma), or biomarkers such as PDL1, ALK, and ATM which have implications for targeted therapies and/or inclusion in clinical trials (5 cases). Conclusion The Hi-C FFPE sequencing technology has the potential to improve the workflow of pathology labs for detection of a wide range of structural variants informing precision diagnosis and treatment for lymphomas.

Abstract Introduction: Brexucabtagene autoleucel (Brexu-cel) is a CD19-targeted chimeric antigen receptor (CAR-)T cell therapy approved for treatment of relapsed/refractory (r/r) B-ALL. Brexu-cel's approval was founded on data from the ZUMA-3 trial, in which 78 patients (pts) were treated at the pivotal dose of 1x10e6 CAR-T cells/kg, resulting in a complete remission (CR) rate of 73%. Three-year follow-up from ZUMA-3 demonstrated median relapse-free and overall survival (RFS/OS) of 11.6 and 25.6 months (mos) for all treated pts. Amongst responders, the median OS was 60.4 mos for those who did not receive a subsequent allogeneic hematopoietic cell transplant (HCT) (n=43), but only 36.3 months for those who did (n=14). This has led some to conclude that HCT may not be beneficial following brexu-cel therapy for r/r B-ALL; however, it must be noted that 29 (37%) of the pts treated on ZUMA-3 received brexu-cel for post-HCT relapse. T cells collected from individuals who relapse in the post-HCT setting are largely of donor origin, making the CAR-T product comparable to a genetically modified donor lymphocyte infusion (DLI). The immunology at play in this scenario may be different from that in which CAR-T cells are of truly autologous origin. Methods: The Real-World Outcomes Collaborative for CAR-T in ALL (ROCCA) consortium database includes pt characteristics and outcomes of brexu-cel therapy given as standard-of-care across 41 US institutions. We identified pts who achieved an MRD negative (neg) CR by either flow cytometry (minimum sensitivity 10e-4) or NGS following brexu-cel for r/r Ph neg B-ALL and categorized them into three groups with regard to use of HCT: Never HCT, Pre-CAR HCT, or Post-CAR HCT. Pts who received second HCT following brexu-cel for post-HCT relapse (n=9) were excluded. Pt/disease characteristics, RFS, and OS were assessed for each group, landmarked at 73 days after brexu-cel infusion (the median time to consolidative allogeneic HCT). Results: In the ROCCA database we identified 165 pts who achieved MRD neg CR following brexu-cel, amongst whom 69 never underwent HCT, 49 were transplanted pre-CAR (ie, brexu-cel served as a genetically modified DLI), and 47 underwent post-CAR consolidative HCT while in CR. The median follow-up is 373 days. The median age was higher in the Never HCT group (49, range 19-83) in comparison with the Pre-CAR HCT (40, 24-72) and Post-CAR HCT (34, 18-70) groups. Thirty-five percent were &gt;60yo in the Never HCT group vs 20% in the Pre-CAR HCT and 9% in the Post-CAR HCT groups. Ph-like disease was present in 38%, 29%, and 43% of the Never HCT, Pre-CAR HCT, and Post-CAR HCT groups, respectively (p=0.35). No significant differences were observed in pre-apheresis bone marrow blasts, presence of CNS disease at apheresis, prior blinatumomab or inotuzumab treatment, or use of bridging therapy across the groups, though there was a higher prevalence of non-CNS extramedullary disease in the Pre- and Post-CAR HCT groups (32, 39%) vs the Never HCT group (13%) (p=0.004). A minority of pts in all groups were deemed to be in MRD neg CR prior to apheresis (6-20%). Median RFS was 260 days in the Never HCT group and not reached in the Pre- and Post-CAR HCT groups (p=0.002), with respective 1-yr RFS of 38%, 64%, and 67%. Median OS was not reached in any group and was similar for all at 1-yr at 68-79% (p=0.13). Characteristics of those in the Never HCT group who were least likely to relapse included age &gt;60 (OR 0.22, CI 0.07-0.73 vs age 18-39, p=0.024) and those with non-Ph-like B-ALL (OR 0.33, CI 0.12-0.94, vs Ph-like, p=0.037) in univariate analyses. Conclusions: Real-world data regarding outcomes following brexu-cel therapy allow evaluation of the role for consolidative allogeneic HCT, which remains one of the most important unresolved questions in the use of CAR-T therapy for r/r B-ALL. This analysis demonstrates that a first consolidative HCT after achieving MRD neg CR with brexu-cel is associated with a significant decrease in relapse. Additionally, use of brexu-cel for post-HCT relapse is also associated with a significantly lower risk of relapse compared with those who never received an allogeneic HCT. With the current duration of followup, OS is not significantly different across the three groups. These data suggest there is a benefit for relapse-free survival in pts receiving an allogeneic HCT at some point in the course of treatment for r/r Ph neg B-ALL.

Abstract Background: B-cell maturation antigen (BCMA)-targeted T cell engagers (TCEs) have emerged as a highly potent immunotherapy for relapsed/refractory multiple myeloma (MM). However, both primary and acquired resistance significantly limit the durability of responses. Antigen escape and development of dysfunctional T cell responses are a significant driver of relapse post-therapy. Here, we preclinically interrogate if continual versus intermittent/response-adapted dosing differently affects development of resistance, the translatability to clinical resistance mechanisms, and how tumor-intrinsic or microenvironmental factors shape the development of resistance to BCMA-TCEs. Methods: We utilized a syngeneic transplantable Vk*MYC MM model which permits clonal tracking through unique immunoglobulin rearrangements. Two cohorts of tumor-bearing mice were treated with a murine surrogate BCMA-TCE using distinct strategies: (1) continuous weekly dosing until disease progression, and (2) an “ intermittent/response-adapted” strategy, where treatment was paused after initial response and resumed upon detection of M-spike. At time of relapse on therapy, RNA-seq was performed on isolated tumor cells to investigate mutations in- or loss of Tnfrsf17/BCMA. Single-cell RNA sequencing (scRNA-seq) was also performed on 189,025 cells isolated from bone marrow and extramedullary sites. Results: Both continuous and intermittent treatment regimens resulted in similar overall survival. BCMA-TCE treatment induced a distinctive pattern of disease progression, with para- and extra-medullary dissemination observed in 31% (17/54) of treated mice—regardless of treatment schedule. Given this treatment-induced dissemination hasn't been historically observed in our model, we further profiled BCMA expression and infiltrating immune cells to understand relapse mechanisms at these sites. Furthermore, we noted lower BCMA expression in tumors from continuously treated mice compared to untreated or stop-and-go cohorts. Importantly, reduced BCMA expression occurred without loss of plasma cell identity indicating that lineage switching may not be occurring as observed in other hematological malignancies treated similarly (Ruella, 2023, Nat Rev Drug Discov); malignant cells retained high expression of canonical plasma cell markers Irf4, Prdm1, Xbp1, Sdc1. We identified three mechanisms of acquired resistance:Genomic BCMA loss: Complete and irreversible loss of BCMA due to retrotransposition of IAP particles into the first intron of Tnfrsf17, disrupting transcription of downstream exons. This represented a genomic mechanism of antigen escape occurring with continual and prolonged TCE dosing, disrupting transcription and eliminating surface BCMA.Transient BCMA downregulation: Transient downregulation of BCMA expression associated with rapid disease relapse under continuous treatment. Tumors exhibited low BCMA levels and widespread dissemination in paramedullary sites. However, re-transplantation into naïve hosts led to restoration of BCMA expression and re-sensitization to TCE, indicating antigen loss was not permanent.Resistance without antigen loss: In the intermittent dosing regimen, several cases achieved complete remission after two doses, relapsed after treatment pause, and were not controlled after subsequent retreatment. Despite preserved BCMA expression and absence of BCMA mutations or deletions, tumors were refractory to retreatment, suggesting a tumor extrinsic mechanism of resistance. scRNA-seq analysis of the tumor microenvironment is ongoing and the role of uniquely identified immune infiltrates, like NK-like lymphocytes and distinct macrophages, in shaping the cell responses is under consideration. Conclusion: Resistance to BCMA-TCE therapy in the Vk*MYC model of MM arises through multiple mechanisms including genomic antigen loss and transient antigen downregulation. Continuous therapy drives selective pressure leading to target loss via genomic or epigenetic routes, while intermittent dosing preserves antigen but permits resistance to TCE, potentially through immune escape mediated by microenvironmental changes. These insights underscore the translatability of the Vk*MYC model for evaluating rational combination therapies to mitigate these resistance mechanisms.
