Objectives To comprehensively review the available literature on prehabilitation and rehabilitation exercise, nutrition, and psychological support interventions for patients with kidney cancer (KC), to summarise the clinically relevant efficacy and cost‐effectiveness of interventions, to expose key knowledge gaps, and to inform future investigations and initiatives. Methods This review was performed according to the per Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) Extension for Scoping Reviews Guidelines. We included randomised controlled trials (RCTs) assessing programmes of prehabilitation or rehabilitation, exercise, psychological support, or nutrition components in patients with KC or KC caregivers from January 2004 to March 2022. Statistically significant positive (SS+) and negative (SS−) results were summarised. Results The systematic search yielded 10 968 records including 18 RCTs, involving 2774 unique subjects, 706 of whom were KC patients/survivors. None included caregivers or assessed cost‐effectiveness. Two interventions were implemented before surgery, one was implemented prior to initiation of systemic therapy, eight were implemented during systemic or radiation therapy, three were implemented after treatment, while implementation time was not specified for four interventions. Conclusion Most (14/18) RCTs involving exercise, nutrition, psychological support, or prehabilitative or rehabilitative programmes for KC performed to date demonstrated SS+ results. The evidence was most robust regarding previously evaluated psychological support, especially mindfulness‐based interventions (9/10 studies demonstrating SS+ improvement in primary outcomes), followed by therapeutically valid exercise with/without psychological support (5/8 RCTs demonstrated efficacy), then nutrition or pharmacological interventions (2/5 demonstrated efficacy). Level 1 evidence supports counselling patients and referral to mindfulness‐based psychological therapy along with physical therapy or physical medicine and rehabilitation, as well as consideration of preoperative carbohydrate drinks. No studies have examined impact on caregivers, or cost‐effectiveness, which are both critical areas for future study.

520 Background: The annual incidence of renal cancer is 0.02% among the general United States population. End stage renal disease (ESRD) and exposure to dialysis are thought to be the primary drivers of increased risk of renal cancer in renal transplant patients rather than immunosuppression. This has been evidenced by how the incidence of RCC in heart transplant recipients is no different than the normal population. In this study, we aim to characterize RCC incidence among kidney transplant patients (usually exposed to ESRD/dialysis) versus other solid organ transplant patients (usually unexposed to ESRD/dialysis). Methods: We used CPT codes to search for patients who had received a solid organ transplant (kidney, liver, heart, lung, pancreas) at all Mayo Clinic sites from 1/1/2018 to 1/1/2024. Within this cohort, we identified those who had been diagnosed with kidney cancer after initiating dialysis or receiving a transplant, and retrospectively extracted data related to demographics, cancer diagnosis, and transplant details. Results: We identified 10873 patients who had received a solid organ transplant (Table 1). Of these, 178 (1.76%) were diagnosed with kidney cancer after either starting dialysis or receiving a transplant. These 178 patients were of median age 56 years at time of cancer diagnosis (STD 12), 71% male, 70% white, 20% black, 4.5% Asian, 2.8% American Native. Of 5792 patients who had received a kidney transplant (with or without another solid organ transplant), 172 (2.97%) were diagnosed with kidney cancer after having started dialysis or receiving a kidney transplant. Of these 172, 156 (91%) were exposed to dialysis (107 primarily hemodialysis and 48 peritoneal). Of 4392 patients who had received a solid organ transplant other than kidney (liver, heart, lung, and/or pancreas), 6 (0.14%) were diagnosed with kidney cancer after having received a kidney transplant. Of these 6, none underwent dialysis. Conclusions: Patients with kidney transplants are at increased risk of kidney cancer compared to patients with non-kidney solid organ transplants (2.97% vs 0.14%). This supports prior evidence showing ESRD plays a significant role in the pathogenesis of kidney cancer.

428 Background: Prostate cancer management presents a significant healthcare burden, with the need to efficiently triage patients for treatment. Our objective is to leverage large language models to predict physician-recommended treatment plans from unstructured clinical notes. By accurately predicting treatment plans, we aim to risk stratify and triage patients effectively, thereby optimizing the allocation of physician resources. Methods: 448 unstructured initial urology consultation patient notes following first positive prostate cancer biopsy were identified. The recommended and final treatments received were manually annotated to establish ground truth labels (Table 1). The dataset was split 80:20 for training and testing, preprocessed to remove plan sections and formatted into question-answer (QA) format. A domain-specific large language model (LLM) inspired by GPT and a specialized tokenizer (PCa- LLM) for prostate cancer terminology were developed. QA models were built using the PCa-LLM and compared with those using GPT-2 as the backbone to predict recommended and final treatments. Results: For the physician-recommended treatment plans, our LLM (PCa-LLM) showed superior performance with higher AUROC scores for curative vs. non-curative treatments (0.78 vs. 0.65), chemo-hormonal vs. other non-curative treatments (0.89 vs. 0.65), and surveillance vs. all other treatments (0.72 vs. 0.70), while both models achieved the same high AUROC of 0.99 for chemo-hormonal vs. all other treatments. For final treatments, PCa-LLM demonstrated better AUROC for curative vs. non-curative treatments (0.77 vs. 0.74) and chemo-hormonal vs. other non-curative treatments (0.71 vs. 0.66), while GPT2 outperformed PCa-LLM for surveillance vs. all other treatments (0.78 vs. 0.70). Both models achieved an AUROC of 0.99 for chemo-hormonal vs. all other treatments. Conclusions: PCa-LLM accurately predicted most treatment categories better than GPT2, with higher AUROC scores, and can be utilized to triage prostate cancer patients using initial consultation notes.

BACKGROUND: Although most transplant centers preferentially offer minimally invasive approaches to donor nephrectomies, there remains less standardization specific to the kidney extraction site. This study aimed to evaluate incisional hernia occurrence in living kidney donors based on kidney extraction site location. STUDY DESIGN: This was a retrospective study of all donors who underwent minimally invasive living donor nephrectomies at the Mayo Clinic Arizona between 2011 and 2023 with a 2-year external validation cohort from Mayo Clinic Florida and Mayo Clinic Minnesota. The cohort was divided into 2 groups based on the kidney extraction site type: midline infraumbilical and Pfannenstiel. RESULTS: In the primary cohort, incisional hernia occurrence was observed in 1.2% of donors with an infraumbilical midline kidney extraction site compared with 0.1% with a Pfannenstiel extraction site (p = 0.04). Donors with an infraumbilical midline kidney extraction site were more likely to be men (50.8% vs 23.3%, p < 0.0001), have a higher BMI (mean 27.2 vs 26 kg/m2, p < 0.0001), and have current or former tobacco use (p = 0.002). There were no differences in incisional hernia occurrence when comparing minimally invasive surgical techniques (p = 0.52). In the external validation cohort, hernia occurrence was observed in 4.5% of donors with a midline incision compared with 0.0% with a Pfannenstiel incision (p = 0.09). Using combined data from the 3 sites, the use of a Pfannenstiel incision as the extraction site was associated with significantly lower odds of developing a hernia compared with the infraumbilical midline incision (odds ratio 0.06, 95% CI 0.008 to 0.456). CONCLUSIONS: Although the risk of hernia in living kidney donors is generally low, the use of a Pfannenstiel incision for kidney extraction appears to offer an additional incremental reduction in risk.

Abstract The study of prehabilitation and rehabilitation ([p]rehabilitation) to alleviate the sequelae of bladder cancer and its treatment has generated numerous opportunities to improve the quality of life of bladder cancer survivors. The authors conducted a scoping review of randomized clinical trials (RCTs) to identify knowledge gaps in and research directions for (p)rehabilitative support for those affected by bladder cancer. The authors systematically searched six databases and synthesized key findings from RCTs conducted from January 1, 2004, through March 15, 2022, that enrolled participants with bladder cancer, survivors, or caregivers in outpatient (p)rehabilitative programs (e.g., exercise, nutrition, or psychological support). Outcomes were characterized according to eight prespecified, clinically relevant categories. The search retrieved 10,968 records, 27 of which met the inclusion criteria, and 24 described unique RCTs with 2471 enrolled participants. Of 24 interventions, 17 (71%) yielded statistically significant results for the outcome of interest. Only one RCT included a cost‐effectiveness analysis, and only two characterized the efficacy of interventions for caregivers. Of 11 RCTs involving psychological support, eight yielded statistically significant results, as did nine of 11 RCTs with physical exercise interventions, three of four RCTs with educational interventions, three of four RCTs with nutritional support interventions, one of two RCTs with pharmacologic medications, and zero of one RCT with physical therapy. The most promising interventions for inclusion in multimodal, personalized (p)rehabilitation programs included exercise, stress management training, cognitive training, smoking and alcohol cessation counseling, immunonutrition, stoma education, and penile rehabilitation. Further studies of the cost effectiveness and efficacy for caregivers of such interventions are needed. Plain Language Summary In a scoping review of all randomized clinical trials involving prehabilitative or rehabilitative diet, exercise, and psychological support interventions for patients with bladder cancer, survivors, and their caregivers, 17 of 24 (71%) interventions yielded statistically significant improvements in the outcome of interest. Clinicians should consider implementing such interventions for those affected by bladder cancer.

Introduction Less than 20% of US adults meet physical activity (PA) recommendations, yet few physicians provide consistent PA counseling. There is limited research on the state of education of PA counseling in medical school curricula. The purpose of this study was to analyze medical students’ perspectives on the current state and perceived quality of PA education in medical school. Methods An online survey was administered to the students of nine United States medical schools in January 2021. Descriptive statistics were used to analyze results. Results Of 5500 invited students, 1182 (21.5%) responded. Only 8% of students received any formal training on PA counseling for patient or self-use throughout their medical education. The majority (64% and 85%, respectively) of respondents felt that both learning more about the benefits of PA and gaining more practical skills in counseling on PA should be requirements to graduate. Students across all medical school years agreed that formal training on patient counseling for PA should be taught more in-depth. Conclusions Medical students believe that PA and exercise physiology should comprise more of medical education curricula. Such training may equip students with the tools they believe they need to adequately treat patients effectively throughout their careers.

Introduction: The current literature regarding both specific interventions and the current level of nutrition education in the United States is scarce. The purpose of this paper is to provide medical student perspectives on both the degree and necessity of nutrition education during medical school. Methods: Medicine in Motion (MM) is a non-profit student-run organization founded in 2018 that aims to address burnout in medicine through physical activity, community service, and philanthropy. MM issued a survey to nine of its chapters in January 2021 to assess a range of topics including burnout, physical activity, and nutrition education. Results: Of 5500 invited students, 1182 (21.5%) responded. An average of 1.2 hours of formal nutrition education per year was reported across all participants. Students who received any degree of nutritional education reported 2.9 hours per year. Most students (57.6%) had not participated in a medical school course that provided formal education in nutrition. Of those that did participate in a nutrition course (42.4%), the course was required for 84.7% of students and the majority (80.1%) received 0-10 hours of nutrition education. Most respondents (88.7%) reported that requiring formal nutrition education should be a graduation requirement and a similar number of students (89.3%) believe medical students should receive formal training on nutrition counseling for patients. The majority (93.3%) of students either somewhat or strongly agreed that understanding the effects of nutrition/eating decisions on the human body is critical to maximizing patient care. Conclusion: Based on prior studies, physicians feel underprepared to provide nutrition counseling to their patients despite the large role poor diet plays in the burden of disease. Most medical students in this cohort believe that understanding nutrition is vital to maximize patient care. Funding and curricular changes should be allocated towards expanding the nutrition curriculum across U.S. medical schools.

PURPOSE: Testing for pathogenic variants can aid in oncologic risk stratification and identification of targeted therapies. Despite known disparities in access to prostate cancer (PCa) care, little has been written about access to germline genetic testing (GGT) for Black men and other historically marginalized populations. This systematic review sought to delineate racial/ethnic disparities in GGT for PCa. METHODS: This systematic review identified articles published from January 1996 through May 2021 in PubMed, Web of Science, and Embase. We included studies that reported rates of GGT in men with PCa in the United States by race/ethnicity as reflective of routine clinical care or research. A narrative synthesis was performed. RESULTS: Of 4,309 unique records, 91 studies examining 50 unique study populations met inclusion criteria. Of these, four populations included men who received GGT through routine clinical care, accounting for 4,415 men (72.6% White and 7.2% Black). The other 46 populations included men who received GGT as part of a research study, accounting for 30,824 men (64.3% White and 21.6% Black). Of these 46 research populations, 19 used targeted methods to increase recruitment from a specific demographic. CONCLUSION: Most studies that report GGT rates by race/ethnicity are in research settings. Many of these studies used targeted recruitment methods and subsequently have a greater proportion of Black men than clinical and US population–based studies. Other historically marginalized populations are not well represented. There remains a knowledge gap regarding the extent of racial disparities in the use of GGT, particularly in the clinical setting.

The burden of cancer and oncologic treatment is reflected not only through morbidity and mortality, but also through impacts on patient quality of life (QoL). However, QoL has not been historically measured or addressed with the same rigorous methodology as traditional disease-related outcomes such as overall survival and progression, as these are driven by objective measurements and events. Prostate cancer (PCa) is one of the most prevalent non-cutaneous cancers in men around the world. Both the cancer and its treatment significantly impact patients’ physical, emotional, sexual, social, and overall QoL. Ensuring assessment and integration of QoL in research and clinical care enables improvement in treatment outcomes that matter most to patients while also facilitating alignment of healthcare priorities with reimbursements. Great strides toward this end have been made over the last decade, but significant room for improvement remains. To ensure high quality, reliable data collection, QoL assessment tools must be psychometrically validated, standardized, widely implemented across trials, and regularly assessed to allow internal and external validity, longitudinal comparative effectiveness research, and quality control. Additional consideration should be taken for instruments used to measure the aspects of QoL specific to minority, caregiver, and elderly populations. Open clinical questions include how providers should weight changes in different QoL subscales and how clinically meaningful difference thresholds should be defined. Review of ongoing clinical trials encouragingly reveals an increased focus on measuring and improving QoL for men with PCa which will inform the way we utilize QoL assessments. However, additional efforts herein described are needed to fully optimize these processes. In summary, this review will explain the rationale for QoL assessments in PCa populations, discuss requirements for effective implementation, describe considerations for vulnerable and under-evaluated populations, and summarize ongoing clinical trials assessing patient QoL.

Physicians have a higher risk of burnout than many other professions, and burnout is associated with less altruistic professional values, worse patient–doctor relationships, and increased medical errors. Burnout begins in medical school, such that institutions should intervene early to facilitate increased engagement in forms of self-care, including but not limited to exercise. Exercise is negatively associated with burnout, but there is limited research on what motivates students to participate in exercise events and how events could be optimally designed to maximize attendance. Students from nine medical schools across the United States were invited to complete an online survey assessing the effectiveness of various factors at increasing participation in exercise events. Of 5500 invited students, 1182 (21%) responded. Mean age was 25 years, 61% were female, and 38% male. Fifty-seven percent identified as White, 26% Asian, and 5% Black. Students reported financial discounts (56%), having all logistics planned by event organizers (46%), and opportunities to find informal mentors (40%) as most likely to increase participation. To increase student participation in wellness events, institutions should prioritize available funding toward strategies that save students time and money while building community across levels of training and departments.
