Introduction The World Health Organization (WHO) endorses male circumcision as an effective human immunodeficiency virus (HIV) prevention intervention in settings where the expected impact is greatest, including Sub-Saharan Africa. Data on cost implications of early infant male circumcision (EIMC) are limited. The ShangRing (SR) is a WHO pre-qualified device for circumcision. We sought to perform a comprehensive cost assessment alongside a randomized controlled trial (RCT) of the SR versus the standard of care Mogen clamp (MoC) for EIMC to enable future scale-up towards a cost-effective HIV prevention strategy. Methods We collected resource utilization and economic data as part of an RCT of infants aged 0–60 days old undergoing EIMC in Kenya, Tanzania, and Uganda. Cost data for both the SR and MoC included baseline facility costs, direct costs, and indirect costs. The Decision Makers Program Planning Tool v1.0 was used to perform a direct cost comparison of these two devices. The Goals model was used to compare the costs of EIMC in 2023 using the present value of money to circumcise an adolescent male 15 years from now. Results A total of 1,378 infant males underwent circumcision, 689 via SR and 689 via MoC. The overall cost of a single EIMC in Kenya, Tanzania, and Uganda were 61.30 United States Dollars ($), $47.14, and $64.59 respectively for the SR, and $56.38, $50.43, and $58.57 respectively for the MoC. In Kenya, EIMC would be less expensive based on nominal present costs in 2023 compared to waiting for adolescent circumcision at age 15 years in 2038. This finding is reversed in Tanzania and Uganda. Conclusions The overall cost of EIMC via SR versus MoC is comparable in an RCT. With scale-up utilizing lower level personnel, the cost of SR may be further reduced. The SR is an attractive alternative for future EIMC initiatives in Sub-Saharan Africa to further reduce HIV burden.

Non-muscle-invasive bladder cancer (NMIBC) comprises approximately 75% of new bladder cancer cases and generally carries a favorable prognosis, yet high rates of recurrence and progression necessitate close surveillance with frequent cystoscopies and repeated transurethral resections. Upfront treatment for high-risk disease is typically Bacillus Calmette-Guérin (BCG), although combinations with immune checkpoint inhibitors have reported results. Patients with BCG-unresponsive, intolerant, or refractory disease represent a subset of patients with high risk of progression, with early radical cystectomy being the standard approach for this setting. Global BCG shortages and the substantial impact of cystectomy on quality of life underscore the need for therapeutic alternatives. Over the past decade, investigational trials in immunotherapy have expanded treatment options for BCG-unresponsive NMIBC with CIS, leading to FDA approval of intravesical nadofaragene firadenovec, nogapendekin alfa-inbakicept, and systemic pembrolizumab. This narrative review summarizes developments in intravesical and systemic immunotherapies for NMIBC, highlights ongoing trials, and addresses controversies in trial design, treatment sequencing, comparative efficacy, and safety.

Purpose: Surgical video review can be used in urologic training, yet significant barriers to the implementation of video review programs exist, and formal assessment of usage and utility for trainees is limited. Here, we evaluate a novel video review platform to describe patterns of use and determine perceived utility. Materials and Methods: We analyzed learning points entered by trainees during video review of radical prostatectomy cases using our surgical intelligence–enabled Film Room platform between September 2023 and July 2024. Learning point content was categorized according to surgical coaching domains as technical, cognitive, nontechnical, or descriptive. Entries were compared by surgical step and level of training. Anonymous surveys were distributed to trainees to determine perceived utility and reveal patterns of video review. Results: Thirteen trainees entered 480 unique learning points across all radical prostatectomy steps and spanning surgical coaching domains during the study period. Learning points varied by training level, with junior trainees entering points more often than senior trainees for Retzius-space dissection ( N = 73 vs 17, p < 0.01) and seminal vesicle and posterior dissection ( N = 58 vs 27, p < 0.01). Trainees used video review in preparation for both upcoming cases and performance analysis. Ninety-four percent of survey respondents reported they either agreed or strongly agreed that video review helped them develop surgical skills. Conclusions: We found usage across training levels and high perceived utility of our Film Room platform for video review of robotic prostatectomy. Implementation of video review platforms holds promise to augment existing urologic training and should be explored further.

Introduction Male circumcision (MC) has been shown to decrease transmission of HIV and is a critical strategy to decrease its incidence in countries with high rates of heterosexually transmitted HIV. Early infant MC (EIMC), with single-use MC devices, could increase rates of MC in Sub-Saharan Africa. Our objective was to determine the safety, efficacy and satisfaction of ShangRing EIMC in resource-constrained environments. Methods Healthy male infants aged 1–60 days underwent ShangRing EIMC performed by non-physician clinicians in 14 sites in Kenya, Tanzania and Uganda. The primary outcomes were the safety and efficacy of ShangRing EIMC. Secondary outcomes were pain related to the procedure, wound healing and parental satisfaction. Male infants were assessed at discharge and on postoperative days 7 and 28 for wound healing and complications. This trial is registered with Clinical.Trials.gov, NCT03338699 , and is complete. Results From the 1697 participants enrolled from February to November 2020, 1691 (99.6%) underwent ShangRing EIMC. Median duration of the procedure was 10 min (IQR 6–13). The mean Neonatal Infant Pain Scale 20 min postprocedure was 0.3 (SD 0.8), indicating no pain. At the time of discharge, 1679 (99.0%) participants had a normal-appearing wound and 1574 (93.1%) demonstrated complete wound healing at 28 days. A total of 17 (1.0%) AEs were reported, most related to bleeding. A total of 1635 (99.1%) of parents were satisfied with the appearance of the circumcised penis at 28 days. Conclusion ShangRing EIMC is a simple and successful MC method that non-physician clinicians can perform safely, with low AE rate, satisfactory wound healing and high satisfaction rate among parents. This indicates that the ShangRing EIMC can be considered a long-term strategic approach to accelerate the scale-up of MC in Sub-Saharan Africa. Trial registration number NCT03338699 .

Background: Longitudinal genomic profiling through serial circulating tumor DNA (ctDNA) testing offers a noninvasive method to monitor clonal evolution in advanced prostate cancer. This study evaluated the frequency and nature of newly emergent and potentially actionable genomic alterations detected through serial testing in a real-world setting. Methods: We conducted a retrospective analysis of advanced prostate cancer patients who underwent multiple Guardant360 ctDNA tests between October 2020 and March 2023. The study focused on identifying new genomic alterations absent in the initial test, with particular attention to alterations relevant for on-label therapies, therapies approved in other oncologic indications (i.e., off-label), or a clinical trial. Results: Among 479 patients with at least two ctDNA tests, the median interval between the first and second evaluable tests was 207 days. New and potentially actionable alterations emerged in 57.8% of patients, including potential targets for on-label therapies (16.7%), off-label therapies (16.5%), and clinical trials (55.7%). Tumor mutational burden (TMB) increased from “low” to “high” in 11% of patients, although none had microsatellite instability or mismatch repair deficiency. In a Mayo Clinic subset, ten patients received olaparib based on treatment-emergent alterations, but none achieved a prostate-specific antigen (PSA) response. Two patients who transitioned from low to high TMB received pembrolizumab, both with progressive disease as best response. Conclusions: In a large real-world cohort, serial ctDNA testing frequently identified new alterations that were not detected at baseline and are potentially actionable therapeutic targets, highlighting the value of serial genomic profiling for capturing clonal dynamics. Additional research is needed to better establish a framework for retesting and to clarify how these results should influence subsequent treatment decisions.

ABSTRACT Purpose The natural history of biochemical recurrence (BCR) after radical prostatectomy (RP) remains understudied, with limited long‐term data from large cohorts inclusive of both salvage radiotherapy (SRT)‐treated and untreated patients. Herein, we sought to evaluate the outcomes of patients with BCR and the impact of SRT on disease progression. Materials and Methods Patients undergoing RP who developed BCR (PSA ≥ 0.20 ng/mL) were included. Patients with BCR treated with SRT were compared to untreated patients using risk‐set matching with time‐dependent propensity scores. The primary outcome was metastases, analyzed using Kaplan–Meier and Cox models. The number needed to treat (NNT) with SRT to prevent progression was derived at 5 and 15 years. Results Among 6881 patients with BCR, 2109 received SRT. At a median follow‐up of 10.2 years, 1147 patients developed metastases. The median PSA at the time of SRT was 0.50 ng/mL. After 1:1 propensity score matching (2109 patients per cohort), SRT significantly reduced the risk of metastases at 5 (12.7% vs. 19.3%, p < 0.0001) and 15 years (28.6% vs. 31.5%, p < 0.001). On multivariable analysis, SRT independently reduced metastasis risk (HR 0.75, 95% CI 0.63–0.90, p = 0.002), translating to NNT of 23 and 15 at 5 and 15 years, respectively. Interaction analyses between SRT and nodal status ( p = 0.04) showed greater metastasis risk reduction in pN+ (HR 0.41, 95% CI 0.22–0.77, p = 0.005) compared to pN− disease (HR 0.81, 95% CI 0.67–0.97, p = 0.02). Conclusions Most patients with BCR post‐RP do not progress to metastasis. For those who do progress, SRT inarguably improves the oncologic outcomes in the BCR setting. However, careful patient selection and shared decision making should be encouraged in order to limit overtreatment and side effects.

382 Background: The natural history of biochemical recurrence (BCR) after radical prostatectomy (RP) is heterogeneous, with most patients not progressing to metastasis. Determining the impact and optimal timing of salvage radiation therapy (SRT) remains challenging, particularly in the absence of prospective randomized trials with a surveillance control arm. Our objective isto quantify the oncologic benefit of SRT among men with BCR after RP. Methods: Patients who underwent RP at Mayo Clinic between 1990 and 2017 and developed BCR (PSA≥0.20ng/mL) were included. Patients treated with SRT were compared to those managed with surveillance using risk-set matching with time-dependent propensity scores, accounting for covariates at BCR and post-BCR. The primary outcome was metastases, analyzed via Kaplan-Meier and Cox proportional hazard models. The number needed to treat (NNT) with SRT to prevent progression was calculated using regression outputs at 5 and 15 years post-BCR. Interaction analyses identified factors modifying SRT’s effect on metastasis. Results: Of 6,881 patients with BCR, 2,109 received SRT. At a median follow-up of 10.2 years, 1,147 patients with BCR developed metastases. After 1:1 matching, SRT was associated with lower metastasis risk than surveillance at 5 years (12.7% vs 19.3%, p<0.0001) and 15 years (28.6% vs. 31.5%, p<0.001). SRT was independently associated with decreased metastasis risk (HR 0.75, 95%CI 0.63–0.90, p=0.002) on multivariable analysis, translating to NNT of 23 and 15 at 5 and 15 years, respectively (Table). Additionally, we noted a significant interaction between PSA at SRT and the association of SRT with metastasis (p-interaction=0.02), such that the reduction in metastatic progression with SRT vs. surveillance was restricted to the cohort of patients who received SRT for PSA>0.40ng/mL (HR 0.66, 95%CI 0.54–0.80, p<0.001). Conclusions: Most patients with BCR post-RP do not develop metastases. Indeed, the NNT with SRT to reduce metastasis versus surveillance indicates a generally indolent disease course. Further, the lack of a significant association of SRT with reduction of metastases in patients with a PSA≤0.40ng/mL underscores the importance of careful patient selection when considering early SRT. Our data establish the rationale for a randomized trial comparing early SRT versus surveillance for appropriately selected patients with BCR after RP.
