Abstract Few studies have reliable estimates on costs of informal care following hospitalization, including health care use and out-of-pocket costs for family caregivers (FCGs) and their care recipients (CR). This presentation discusses results from a Transitional Palliative Care (TPC) intervention on healthcare use and out-of-pocket spending for both FCGs and CRs. The study used data from the Technology-Enhanced TPC study, a trial comparing the TPC intervention to support FCGs of seriously ill CRs to an attention control condition. TPC FCGs received teaching, guidance, and counseling via video calls for 8 weeks following CR hospital discharge. After discharge, a research assistant called FCGs once a month for up to 6 months or CR death to collect healthcare utilization (e.g. outpatient, emergency department, and hospital), out-of-pocket healthcare spending (e.g. deductibles and coinsurance), and health-related travel costs (e.g., transportation, lodging, food) for FCGs and CRs. Incidence rate ratios (IRR) were estimated using negative binomial regressions. The study included 282 FCG-CR dyads across 3 US states. TPC reduced nights in the hospital for CR (IRR = 0.75; 95% CI = 0.56 – 0. 99). Total out-of-pocket spending was not significantly different for TPC versus control; however, TPC dyads reported lower lodging costs (IRR = 0.71; 95% CI = 0.56-0.89). Across groups, mean out-of-pocket spending for dyads was $1401.85, with healthcare payments contributing $1048.58 and transportation expenses contributing $136.79. This study contributes to evidence that palliative care interventions reduce unnecessary hospitalization for seriously ill patients, yet the financial costs to caregivers remain high.

Abstract Recruiting family caregivers to participate in research, especially caregivers of people with severe or life limiting illnesses transitioning from hospital to home, is challenging. Traditional approaches for recruitment, including recruitment done on site at clinics or hospitals, became impracticable during the COVID-19 pandemic, leading to shifts toward virtual or remote recruitment and consent. In this presentation, Dr. Gustavson will compare the success of these two methodological approaches, in-person and remote recruitment and consent, used in the Technology-Enhanced Transitional Palliative Care (TPC) study. She found that the rate of recruitment and consent done in-person was 28% and the rate of remote recruitment and consent was 23%. Those recruited and consented remotely were more likely to be younger, white, have greater than high school education, and were children of or had another non-spousal relationship to the care recipient. She discusses the limitations and benefits of each recruitment modality, including the impact on representativeness of the study sample.

Abstract In the research literature and amongst grant reviewers, there are persistent questions about whether internet connectivity challenges, especially in rural populations, will limit the potential for virtual or decentralized clinical trials to improve participation of underrepresented groups. In clinical practice, e-health and telehealth advancements have been touted as potential models of care to address health disparities associated with access to care, but without reliable internet connectivity, these disparities may perpetuate or even widen. In this presentation Dr. Holland examines the prevalence of connectivity problems during the Technology-Enhanced Transitional Palliative Care (TPC) study, a virtual clinical trial across three Midwestern states, and provides guidance on the challenges faced. Data are from structured notes from nurse interventionists who documented any connectivity issues in the study’s electronic health record. Of the 1003 visits reviewed, only 11% of visits (115/1003) contained a documented problem with internet connectivity. None of the participants withdrew from the trial due to problems with their internet connections. The findings support the effective use of virtual visits in research involving participants living in rural locations. Virtual randomized controlled trials provide a strategy that enables participation for rural individuals who may not otherwise have access to clinical trials conducted in-person in urban settings. Utilizing internet access to connect with and support people who live in rural areas is critically needed to advance clinical research.

Abstract In this presentation, Dr. Griffin will describe the Technology-Enhanced Transitional Palliative Care (TPC) study, a randomized controlled trial testing the efficacy and cost-effectiveness of an intervention to address FCGs’ unmet needs in order to improve their health and well-being. Nurse interventionists use video visits to teach, guide and counsel FCGs in rural areas caring for someone receiving palliative care and transitioning form hospital to home. In addition to providing background on the importance of addressing unmet family caregiver needs during care transitions for patients receiving palliative care, she will describe the study design, sample, intervention and control group procedures, including the use of video visits, and outcomes assessed. This presentation will provide necessary context for the remaining presentations.

Abstract Background Temozolomide (TMZ) treatment has demonstrated a variable impact on glioma prognosis. This study examines associations of survival with DNA repair gene germline polymorphisms among glioma patients who did and did not have TMZ treatment. Identifying genetic markers which sensitize tumor cells to TMZ could personalize therapy and improve outcomes. Methods We evaluated TMZ-related survival associations of pathogenic germline SNPs and genetically predicted transcript levels within 34 DNA repair genes among 1504 glioma patients from the University of California San Francisco Adult Glioma Study (UCSF AGS) and Mayo Clinic, whose diagnoses spanned pre- and post-TMZ eras within the major known glioma prognostic molecular subtypes. Results Among those who received TMZ, 5 SNPs were associated with overall survival, but not in those who did not receive TMZ. Only rs2308321-G, in MGMT, was associated with decreased survival (hazard ratio = 1.21, P = .019) for all glioma subtypes. Rs73191162-T (near UNG), rs13076508-C (near PARP3), rs7840433-A (near NEIL2), and rs3130618-A (near MSH5) were only associated with survival and TMZ treatment for certain subtypes, suggesting subtype-specific germline chemosensitization. Genetically predicted elevated expression of PNKP, compared to normal brain expression, was associated with markedly poor survival in TMZ-treated patients with isocitrate dehydrogenase (IDH)-mutant and 1p/19q non-codeleted gliomas (P = .015), with a median difference of over 70 months in overall survival times. Similarly, NEIL2 and TDG expressions were associated with altered TMZ-related survival only among certain subtypes. Conclusions Functional germline alterations within DNA repair genes were associated with TMZ sensitivity, measured by overall survival among adults with glioma. These variants should be evaluated in prospective analyses and functional studies.

The NCCN Guidelines for Survivorship include recommendations for screening, evaluation, and treatment of psychosocial and physical problems resulting from adult-onset cancer and its treatment. They also include recommendations to promote healthy behaviors and immunizations in survivors and provide a framework for care coordination. These NCCN Guidelines Insights summarize the panel’s current recommendations regarding sexual health and fertility.

The emergence of pathologist-driven molecular reflex testing for tumoural biomarkers is a significant advancement in cancer diagnostics, facilitating targeted cancer therapy for our patients. Based on our experience, the Canadian landscape of pathologist-driven reflex biomarker testing for melanoma lacks standardization and is plagued by a lack of awareness by pathologists and clinicians. This paper comprehensively examines the approaches to reflex biomarker testing for melanoma patients across Canada, highlighting the regional variations in the criteria for initiating molecular testing, the biomarkers tested, and the molecular techniques employed. We also discuss the clinical relevance of biomarkers, emphasizing their alignment with the National Comprehensive Cancer Network ® (NCCN ® ) Clinical Practice Guidelines in Oncology (NCCN Guidelines ® ) as well as ancillary tests such as BRAF VE1 immunohistochemistry to detect BRAF V600E mutation and molecular techniques such as real-time polymerase chain reaction, matrix-assisted laser desorption ionization-time of flight mass spectrometry and next-generation sequencing. Our proposed standardized minimum criteria for reflex testing prioritize melanomas with Breslow thickness >4 mm or disseminated disease, who will most benefit from enhanced delivery of biomarkers and expedited access to targeted therapies while attempting to balance cost-effectiveness and utilization of public healthcare resources with patient outcomes.

ABSTRACT Background Tricuspid valve‐in‐valve (TVIV) implantation has traditionally included post‐procedure overnight in‐hospital observation with next‐day discharge. Recently, our practice has shifted toward same‐day discharge for most patients after vascular access site hemostasis and adequate recovery from anesthesia. However, data on the safety of this approach remains scarce. Aims Our study aims to describe our practice change and to identify factors that may lead to overnight observation post‐TVIV. Methods We retrospectively reviewed medical records of patients who underwent uncomplicated TVIV implantation as an outpatient procedure at Mayo Clinic between 2011 and 2023. Results Of the 83 patients who underwent TVIV from 2011 to 2023, 65 (78%) were included in the study. The first 39 patients in our institutional series were observed overnight as standard practice. 18 (69%) of the most recent 26 patients in our series were discharged the same day; three patients who remained in the hospital overnight were because of provider preference and/or patient preference without any specific medical concern. Of all 47 patients who were observed overnight, one patient was treated for fluid overload, one patient had non‐sustained ventricular tachycardia on telemetry that resulted in adjustment of antiarrhythmic therapy, two patients had continued bleeding from the access sites and was observed for another day. Among the two of them, one also developed atrial tachyarrhythmias requiring initiation of additional antiarrhythmic therapy. Out of 18 patients discharged the same day, one patient had an ED presentation within 24 h due to access site bleeding which was resolved promptly. There was no mortality or procedural‐related readmission. Conclusion Same‐day discharge may be considered for adult patients who have undergone uncomplicated TVIV with adequate hemostasis and recovery after anesthesia.

Background: Management of cytokine release syndrome (CRS) with chimeric antigen receptor T cell therapy (CAR-T) has evolved in the last decade. First line treatment tocilizumab (toci) was initially given for grade 2 or higher CRS in clinical trials (Toci/CRS≥2). Earlier use of toci in grade 1 CRS was found to be safe without negative impact on clinical response in cohort 4 of ZUMA-1 study for axicabtagene ciloleucel (axi-cel) for B-cell non-Hodgkin lymphoma (NHL; Toci/CRS1). This practice was also adopted for other CAR-T therapies for other disease indications. Subsequently, FDA also updated the package insert for axi-cel in 2021 to include the use of prophylactic dexamethasone (ppx dex) to be given on days 0, 1, 2 of CAR-T infusion based on the results from cohort 6 of ZUMA-1. We examined CRS and ICANS (immune effector cell associated neurologic syndrome) outcome of patients who received FDA approved axi-cel in standard-of-care (SOC) practice with these evolving practices. Of note, adoption of ppx dex has been variable across CAR-T treatment centers in the US (Khurana et al, Blood 2022). At Mayo Clinic Rochester, patients considered high-risk for severe CRS/ICANS (those who received bridging therapy and had LDH above upper limit of normal and/or with secondary CNS involvement or other CNS pathologies) would be considered for ppx dex. Methods: Medical records of patients who received axi-cel in SOC between 2018 and 2023 at Mayo Clinic Rochester were reviewed. ASTCT guideline was used for CRS and ICANS grading. Categorical variables were compared using Chi-squared test and continuous variables were compared using Kruskal-Wallis test. Results: Among 187 pts receiving SOC axi-cel, the median age was 60 years and 121 (65%) were males, 152 (81%) had CRS, of which 73 (39%) were grade ≥2; 97 (52%) had ICANS, of which 65 (35%) were grade ≥2. Of the 152 CRS pts, 54/152 (36%) pts never received toci or ppx/dex. Of the pts who received Toci, 35/152 (23%) received Toci when CRS is at least grade 2 (Toci/CRS≥2), 49/152 (32%) received Toci/CRS1 without ppx dex (Toci/CRS1), and 14 (9%) received ppx dex with Toci given in CRS1 when pts developed CRS (PPX DEX). Baseline demographics were comparable except age (Toci/CRS≥2: 58y; Toci/ CRS1: 63y; ppx dex: 50y; p=0.001) and pre-LD CRP (Toci/CRS≥2: 34mg/L; Toci/ CRS1: 6mg/L; ppx dex: 16mg/L; p=0.002). Pre-LD LDH and ferritin were also comparable. PPX DEX or Toci/CRS1 had significantly lower rate of maximum grade CRS≥2 (PPX DEX: 4 (29%); Toci/ CRS1: 20 (41%); 35 (100%); p<0.001) and duration of CRS (PPX DEX: 2.5d; Toci/ CRS1: 3d; Toci/CRS≥2: 5d; p<0.001). Time to onset of CRS was not statistically different between the 3 groups. Not surprisingly, Toci/CRS1 group had higher overall rate of toci use, compared to . Interestingly, use rate of ≥2 doses of Toci or siltuximab was significantly higher in Toci/CRS1 or PPX DEX (PPX DEX: 8 (57%); Toci/ CRS1: 26 (53%); 9 (26%); p=0.02). Pt who received PPX DEX or Toci/CRS1 had a significantly lower rate of ICANS (PPX DEX: 6 (43%); Toci/ CRS1: 33 (67%); 32 (91%); p=0.001) and rate of max grade ICANS ≥2 (PPX DEX: 3 (21%); Toci/ CRS1: 23 (47%); 27 (77%); p<0.001). The time to onset and duration of ICANS was not different among the 3 groups. Conclusion: Our real-world study shows that earlier use of Toci in grade 1, compared to its first use in grade 2, can result in lower overall incidence of more severe CRS, duration of CRS, incidence of ICANS and more severe ICANS. While we selected patients at higher risk for having more severe CRS in our PPX DEX cohort, experience to date suggests that these patients, compared to toci/CRS>=2 cohort, could also have reduced severity of CRS and ICANS with this updated management.

Introduction: Outcomes from multidisciplinary lymphoma tumor boards in the molecular era are limited, and the effects of transitioning to virtual formats during the COVID-19 pandemic are not well-documented. This study evaluates how the transition of the Mayo Clinic Lymphoma Tumor Board to a virtual format has impacted its effectiveness and operations. The board, part of the International Mayo Clinic Care Network (MCCN), involves case presentations, subspecialist reviews, and collaborative recommendations. Methods: The Mayo Clinic Lymphoma Tumor Board, an integral part of the Mayo Clinic Care Network (MCCN), conducted a comprehensive review of lymphoma cases from 2014 to 2024. The board's review process involves a structured approach including the presentation of clinical case details, radiology and hematopathology findings, proposed treatment options, relevant literature review, and discussions. From 2014 to 2024, the Mayo Clinic Lymphoma Tumor Board reviewed a total of 722 patients. The review process involves a multidisciplinary team, including physicians, pharmacists, clinical research associates, and trainees. Recommendations and changes related to radiology interpretation, pathologic diagnosis, and treatment approaches were documented and tracked prospectively. In March 2020, the board transitioned to a virtual format due to the COVID-19 pandemic. This shift allowed for remote participation and continued collaborative review while maintaining the board's structured approach and documentation practices. Results: In a total of 722 patients, changes in care were identified in 423 patients, including 287 with newly diagnosed lymphoma and 136 with relapse or refractory disease. Among those who experienced changes, 94 had diffuse large B-cell lymphoma, 49 had follicular lymphoma, 39 had marginal zone lymphoma, 36 had classical Hodgkin lymphoma, and 29 had mantle cell lymphoma. Prior to the COVID-19 pandemic, 431 patients were analyzed, with 217 (50.3%) experiencing changes. A total of 268 changes were documented among these patients. Changes in radiologic interpretation occurred in 9 patients (2.1% of 431 total patients). Pathologic diagnosis changes were noted in 42 patients (9.7%). Additional testing was recommended for 73 patients (16.9%), and clinical management was altered for 144 patients (33.4%). After transitioning to a virtual format, 291 patients were reviewed post-COVID, with 206 (70.8%) having recommended changes. The total number of change recommendations was 322, reflecting increases across all components compared to previous data, with adjustments for varying numbers of patients reviewed. Specifically, radiologic interpretation changes occurred in 21 patients (7.2%), pathologic diagnosis changes in 57 patients (19.6%), additional testing recommendations for 85 patients (29.2%), and clinical management alterations in 159 patients (54.7%). Conclusion: Transitioning to a virtual format in the Mayo Clinic Lymphoma Tumor Board's continued to demonstrate the effectiveness, with increased changes in diagnostic interpretations and clinical management. These results illustrate the potential of virtual tumor boards to improve collaborative decision-making and adapt to evolving clinical needs.
