Abstract Introduction Prostate cancer (CaP) significantly impacts Black men, who face higher morbidity despite lower overall mortality. The disease and its treatments profoundly affect sexuality, relationships, and quality of life (QoL), necessitating robust support systems. Healthcare, spousal support, community involvement, and interactions with other survivors are crucial for enhancing survivors' self-esteem and daily functioning. Virtual town halls offer a platform to share trusted information and foster community support, overcoming geographic and structural barriers. This town hall event will explore Black CaP survivors' experiences, focusing on sexuality post-diagnosis and related medical and psychological needs. MethodsOn June 13, 2024, The University of Oklahoma and Stephenson Cancer Center will host the 5th town hall event (via Microsoft Teams) to address Black CaP survivors' sexual health concerns. Previous town halls averaged 70 attendees and covered various aspects of the CaP journey. This event will include storytelling and panel discussions, with presentations from two CaP survivors and their spouses on personal experiences and coping strategies. A urologic oncologist will discuss treatment advancements and early detection, while a clinical health psychologist will address psychological and emotional aspects of survivorship. Simultaneous watch parties will be held in Milledgeville, Georgia, and Dallas, Texas. Interactive Q&A sessions will allow participant engagement. Attendees will complete a post-event survey to assess the session's impact and collect clinical and sociodemographic data. Quantitative data will be analyzed using SPSS v28, and audio-recorded sessions will be transcribed and thematically analyzed using Nvivo. Results will be available by the end of June and presented at the conference. Expected Results Participants will gain a deeper understanding of the intersection between CaP and sexuality in Black men's health. Discussions will highlight the psychological impact of a cancer diagnosis, challenges in maintaining sexual health during and after treatment, and the role of mental health support. The town hall aims to emphasize the importance of a strong support system, providing valuable coping skills through shared experiences and expert insights. Topics will include the emotional and psychological impact of sexual health challenges, partner support, and the necessity of open communication with healthcare providers. The event seeks to improve CaP survivors' QoL by emphasizing continuous education and integrating sexual health into overall survivorship care. Conclusion This town hall event aims to bridge gaps in understanding and addressing Black CaP survivors' sexual health concerns. By fostering open dialogue and providing expert insights, we hope to improve these men's QoL and survivorship care, emphasizing mental health support, spousal support, and continuous education.

AbstractObjectiveThis study aims to compare the long‐term outcomes of Aquablation for small‐to‐moderate (30–80 cm3) prostates with the outcomes for large (80–150 cm3) prostates at 5‐year follow up.MethodsThe Waterjet Ablation Therapy for Endoscopic Resection of Prostate Tissue (WATER; NCT02505919) is a prospective, double‐blind, international clinical trial encompassing 116 patients, examining Aquablation versus transurethral resection of the prostate (TURP) for LUTS/BPH in prostates sized between 30 and 80 cm3. In parallel, WATER II (W‐II; NCT03123250), a prospective, multicentre, single‐arm international clinical trial, explores Aquablation outcomes in prostates ranging from 80 to 150 cm3. Baseline parameters and 60‐month outcomes were scrutinized using statistical analyses, including Students' t test, Wilcoxon tests for continuous variables, and Fisher's test for binary variables.ResultsThere is a significant improvement in International Prostate Symptom Score (IPSS) from baseline to 60 months in both WATER (22.9 to 7.0) and WATER II (23.2 to 6.8) (P = 0.852). Urinary flow rate (Qmax) increased in both groups from baseline to 60 months (WATER: 9.4 to 17.3 cc/s; WATER II: 8.7 to 17.1 cc/s) (P = 0.933). Immediate and sustained enhancements were observed in IPSS and Qmax. At 5 years, a notable percentage of patients in both groups were BPH medication‐free (WATER: 99%; WATER II: 94%) (P = 0.0517) and free from surgical retreatment (WATER: 95%; WATER II: 97%) (P = 0.508).ConclusionsThe 5‐year follow‐up affirms that Aquablation therapy exhibits sustained outcomes, minimal irreversible complications, and low retreatment rates for treating LUTS/BPH, irrespective of prostate volume ranging from 30 to 150 cm3.

AbstractBackgroundThe psychological and cardiovascular health impacts on family members of patients who have been diagnosed with cancer have not been well characterized. The purpose of this study is to determine whether a family member’s cancer diagnosis influences the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients affected by cancer.MethodsThis retrospective cohort analysis evaluated the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients diagnosed with a genitourinary cancer between 1990 and 2015 compared to relatives of those not diagnosed with a genitourinary cancer. The Utah Population Database was used and familial linkage was determined. Follow‐up included 1‐, 3‐, and 5‐year intervals. Patients residing outside of Utah and first‐degree relatives and spouses with psychological or cardiovascular disease diagnosed before a family member’s cancer diagnosis were excluded.ResultsA total of 49,284 patients with a genitourinary cancer were identified with 77,938 first‐degree relatives and spouses. A matched control group included 246,775 patients with 81,022 first‐degree relatives and spouses. Via Cox proportional hazards models, a 10% increased risk of developing a psychological illness (hazard ratio [HR], 1.10; 95% CI, 1.00–1.20) and a 28% increased risk of developing cardiovascular disease (HR, 1.28; 95% CI, 1.17–1.41) at 1 year after a family member’s cancer diagnosis were found.ConclusionsThis study provides population‐level evidence to support the hypothesis that cancer diagnoses will lead to adverse health outcomes for family members of patients with cancer. Increased clinical attention and support are needed to reduce the harm to families caused by cancer.

PURPOSE Chronic lymphocytic leukemia (CLL)–phenotype monoclonal B-cell lymphocytosis (MBL) is a premalignant condition that is roughly 500-fold more common than CLL. It is unknown whether the two-fold increased risk of developing melanoma associated with CLL extends to individuals with MBL. METHODS Using the Mayo Clinic Biobank, we identified participants who were 40 years or older with no previous hematological malignancies, who resided in the 27 counties around Mayo Clinic, and who had available biospecimens for screening. Eight-color flow cytometry was used to screen for MBL. Individuals with MBL were classified as low-count MBL (LC-MBL) or high-count MBL on the basis of clonal B-cell percent. Incident melanomas were identified using International Classification of Diseases codes and confirmed via medical records review. Cox regression models were used to estimate hazard ratios (HRs) and 95% CI. RESULTS Of the 7,334 participants screened, 1,151 were identified with a CD5-positive MBL, of whom 1,098 had LC-MBL. After a median follow-up of 3.2 years (range, 0-13.5), 131 participants developed melanoma, of whom 36 individuals were positive for MBL. The estimated 5-year cumulative incidence of melanoma was 3.4% and 2.0% among those with and without MBL, respectively. After adjusting for age, sex, and history of previous melanoma, individuals with MBL exhibited a 1.86-fold (95% CI, 1.25 to 2.78) risk of melanoma. This elevated risk persisted when analysis was restricted to those without a history of melanoma (HR, 2.05 [95% CI, 1.30 to 3.23]). Individuals with LC-MBL had a 1.92-fold (95% CI, 1.29 to 2.87) increased risk of developing melanoma overall and a 2.74-fold increased risk (95% CI, 1.50 to 5.03) of melanoma in situ compared with those without MBL. CONCLUSION LC-MBL is associated with an approximately two-fold increased risk of melanoma overall and a 2.74-fold increased risk of melanoma in situ.

Abstract Background The authors previously developed an artificial intelligence (AI) to assist cytologists in the evaluation of digital whole‐slide images (WSIs) generated from bile duct brushing specimens. The aim of this trial was to assess the efficiency and accuracy of cytologists using a novel application with this AI tool. Methods Consecutive bile duct brushing WSIs from indeterminate strictures were obtained. A multidisciplinary panel reviewed all relevant information and provided a central interpretation for each WSI as being “positive,” “negative,” or “indeterminate.” The WSIs were then uploaded to the AI application. The AI scored each WSI as positive or negative for malignancy (i.e., computer‐aided diagnosis [CADx]). For each WSI, the AI prioritized cytologic tiles by the likelihood that malignant material was present in the tile. Via the AI, blinded cytologists reviewed all WSIs and provided interpretations (i.e., computer‐aided detection [CADe]). The diagnostic accuracies of the WSI evaluation via CADx, CADe, and the original clinical cytologic interpretation (official cytologic interpretation [OCI]) were compared. Results Of the 84 WSIs, 15 were positive, 42 were negative, and 27 were indeterminate after central review. The WSIs generated on average 141,950 tiles each. Cytologists using the AI evaluated 10.5 tiles per WSI before making an interpretation. Additionally, cytologists required an average of 84.1 s of total WSI evaluation. WSI interpretation accuracies for CADx (0.754; 95% CI, 0.622–0.859), CADe (0.807; 95% CI, 0.750–0.856), and OCI (0.807; 95% CI, 0.671–0.900) were similar. Conclusions This trial demonstrates that an AI application allows cytologists to perform a triaged review of WSIs while maintaining accuracy.

ImportanceExposure to repetitive head impacts (RHI) is associated with increased risk for neurodegeneration. Accumulation of toxic proteins due to impaired brain clearance is suspected to play a role.ObjectiveTo investigate whether perivascular space (PVS) volume is associated with lifetime exposure to RHI in individuals at risk for RHI-associated neurodegeneration.Design, Setting, and ParticipantsThis cross-sectional study was part of the Diagnostics, Imaging, and Genetics Network for the Objective Study and Evaluation of Chronic Traumatic Encephalopathy (DIAGNOSE CTE) Research Project, a 7-year multicenter study consisting of 4 US study sites. Data were collected from September 2016 to February 2020 and analyses were performed between May 2021 and October 2023. After controlling for magnetic resonance image (MRI) and processing quality, former American football players and unexposed asymptomatic control participants were included in analyses.ExposurePrior exposure to RHI while participating in American football was estimated using the 3 cumulative head impact indices (CHII-G, linear acceleration; CHII-R, rotational acceleration; and CHII, number of head impacts).Main Outcomes and MeasuresIndividual PVS volume was calculated in the white matter of structural MRI. Cognitive impairment was based on neuropsychological assessment. Linear regression models were used to assess associations of PVS volume with neuropsychological assessments in former American football players. All analyses were adjusted for confounders associated with PVS volume.ResultsAnalyses included 224 participants (median [IQR] age, 57 [51-65] years), with 170 male former football players (114 former professional athletes, 56 former collegiate athletes) and 54 male unexposed control participants. Former football players had larger PVS volume compared with the unexposed group (mean difference, 0.28 [95% CI, 0.00-0.56]; P = .05). Within the football group, PVS volume was associated with higher CHII-R (β = 2.71 × 10−8 [95% CI, 0.50 × 10−8 to 4.93 × 10−8]; P = .03) and CHII-G (β = 2.24 × 10−6 [95% CI, 0.35 × 10−6 to 4.13 × 10−6]; P = .03). Larger PVS volume was also associated with worse performance on cognitive functioning in former American football players (β = −0.74 [95% CI, −1.35 to −0.13]; P = .04).Conclusions and RelevanceThese findings suggest that impaired perivascular brain clearance, as indicated by larger PVS volume, may contribute to the association observed between RHI exposure and neurodegeneration.

OBJECTIVE Chordomas are rare tumors that originate from undifferentiated remnants of the notochord. Currently, there are no established guidelines regarding the choice of adjuvant radiation modality for patients surgically treated for chordomas. Using a nationwide, multicenter database, the authors aimed to compare long-term survival outcomes associated with the use of proton or photon adjuvant therapy for the management of chordomas of skull base and spine. METHODS The National Cancer Database (NCDB) was queried for chordoma cases from 2004 to 2017. Patient, tumor, and treatment characteristics were extracted from the database. The primary outcome was overall survival (OS). Kaplan-Meier survival analyses were conducted to investigate differences in outcome on propensity score–matched cohorts of patients treated with proton or photon adjuvant radiotherapy. RESULTS Of the 3490 patients available, 424 met the inclusion criteria for this study. In the prematching analysis, patients receiving adjuvant photon therapy were significantly older (median age 57.0 vs 45.0 years, p < 0.001) and were more commonly male (61% vs 43%, p < 0.001) compared with those receiving proton therapy. Races were equally distributed among radiotherapy modalities (p = 0.64). Patients with chordomas of the mobile spine or sacrum were less likely to receive proton compared with photon therapy (37% vs 58%). Patients receiving proton therapy were more often represented among private insurance holders (69% vs 52%, p < 0.001) as well as in the highest income quartile (52% vs 40%, p = 0.008). Patients traveled farther to receive proton, as opposed to photon, therapy (median 59.0 vs 34.9 miles, p < 0.001). On postmatching Kaplan-Meier analysis encompassing all chordoma cases, no difference in OS between photon and proton therapy was revealed (HR 0.75, 95% CI 0.39–1.44; p = 0.39). A Kaplan-Meier analysis only including patients with skull base chordomas reached similar results (HR 0.83, 95% CI 0.31–2.22; p = 0.71). In patients with spine chordomas, however, a significant difference was found, as proton therapy exhibited a superior OS over photon therapy (HR 0.28, 95% CI 0.09–0.81; p = 0.012). CONCLUSIONS Based on this nationwide analysis, patients with private insurance and higher income were more likely to receive proton adjuvant radiotherapy, while those with spinal or sacral chordomas were less likely to receive this modality. Despite this disparity, an OS benefit was observed in patients with chordomas of the spine and sacrum who received adjuvant proton therapy, in comparison with a matched cohort of patients treated with photon therapy. Conversely, this advantageous outcome was not evident in cases of chordomas located at the skull base.
