ABSTRACTIntroductionArtificial Urinary Sphincter (AUS) placement is the preferred treatment for moderate to severe incontinence following prostate cancer treatment. While device related outcomes related to device survival are well reported, literature on quality‐of‐life outcomes, including the use of validated measures is limited.MethodsWe queried a prospectively maintained database of male patients undergoing primary AUS implantation from 2015 to 2023 at our institution. All patients completed a preoperative Michigan Incontinence Symptom Index (M‐ISI) and Patient Global Impression of Improvement (PGI‐I). Postoperative quality of life data was obtained by mailed correspondence. Surveys obtained following AUS reoperation/revision were excluded. Pairwise comparisons were performed between preoperative functional status and the Postoperative responses. Logistic regression analysis was performed to identify preoperative variables associated with a favorable PGI‐I score defined as “very much better or much better,” or a decrease in pad usage from > 1 pad per day to ≤ 1 pad per day.ResultsDuring the study timeframe, 383 patients underwent primary AUS placement, of which 163 patients (42%) completed a postoperative survey and were included in the study. Median age was 69.0 (IQR: 64–74) and 54.6% of patients had a history of pelvic radiation. The median time from surgery to the postoperative survey was 2.2 years (IQR: 0.9, 4.3). Compared to baseline, following AUS placement there was a significant improvement in the total M‐ISI score (10 [6, 16) vs 26 [22, 30]; p < 0.0001) (Minimally Important Difference = 4). This included improvements in the SUI subscore [4 (IQR 2, 6) vs 10 (IQR: 9, 12); p < 0.0001] and bother score [1 (IQR: 0, 3) vs 6 (IQR: 5, 7); p < 0.001)]. Pad usage significantly decreased following device placement (p < 0.0001). The vast majority of patients (90.7%) would “definitely or probably recommend to a friend/family member.” On univariable analysis, active smoking (ref. never) was associated with adverse pad use outcomes (OR: 0.1, 95% CI: 0–0.8; p = 0.03) and older age was associated with adverse PGI‐I outcome (OR: 0.93, 95% CI: 0.87–0.99; p = 0.02).ConclusionsFollowing AUS implantation, most patients have significant improvement in validated quality of life outcomes and low pad usage. These findings persist despite multiple preoperative comorbidities and should be considered when counseling patients before AUS placement.

Objectives To evaluate the benefit of neoadjuvant chemotherapy (NAC) for patients with high‐risk upper tract urothelial carcinoma (UTUC) using a large, well‐curated multi‐institutional database. Patients and Methods This study was a multi‐institutional retrospective analysis conducted by the UTUC Collaborative Network (UCAN), combining data from 2276 patients with UTUC who underwent radical nephroureterectomy at seven high‐volume tertiary care centres in the United States. The UCAN data were analysed to evaluate the impact of response to NAC on survival outcomes in patients with UTUC. Results A total of 378 patients in the UCAN database underwent NAC. On final surgical pathology, 101 patients (26.8%) had ≤ypT1N0 disease and were defined as NAC treatment responders. Patients who responded to NAC had significantly longer overall survival (OS) and progression‐free survival (PFS) compared to non‐responders. At 5 years post‐surgery, 81.5% of responders were alive compared to 59.8% of non‐responders. The median OS and PFS times among non‐responders were 7.0 years (95% confidence interval [CI] 5.6–9.7) and 6.0 years (95% CI 4.6–9.3) respectively, while the median OS and PFS were not reached among responders. Limitations of this study include its retrospective design, heterogeneity in chemotherapy regimens, and the absence of clearly defined patient selection criteria for treatment. Conclusion These data suggest that NAC can play a pivotal role in the treatment of well‐selected UTUC patients who respond positively. Non‐responders had clearly inferior outcomes. More work is needed to find predictors of response which can improve patient selection.

Objective To define the natural history, patterns of recurrence and treatment modalities for local prostate cancer (PCa) recurrence following radical prostatectomy (RP) and radiation therapy (RT), and to investigate factors that could predict metastasis‐free survival (MFS) in this unique patient population. Methods We queried a prospectively maintained PCa registry to identify men developing in‐field recurrence (IFR) following RP and RT from 2008 to 2021 at a single institution. IFR was defined as biopsy‐proven recurrent PCa or the presence of persistent positron emission tomography‐avid lesions in the prior radiation field without evidence of metastasis. Cox regression was conducted to determine predictors of MFS. Kaplan–Meier methods were used to calculate MFS, cancer‐specific survival (CSS) and overall survival (OS) for patients in three primary therapy categories: cryoablation, androgen deprivation therapy (ADT) alone, and surveillance. Results Of 4575 patients from our registry, 108 (2.3%) with IFR were identified. The median (interquartile range [IQR]) time to IFR from salvage treatment was 78 (50–126) months. A total of 29 patients (26%) were managed with cryoablation, 23 (21%) with ADT, and 28 (25%) with surveillance. The median (IQR) follow‐up was 76 (48–100) months. There were no statistically significant differences in MFS ( P = 0.67) or OS ( P = 0.07) among the three primary treatment cohorts. Patients treated with ADT or cryoablation had longer CSS compared to patients managed with surveillance ( P = 0.047). Conclusions We found that IFR may present years after completion of primary treatment for PCa. While curative management strategies may be attempted, local and distant metastatic recurrence is common and often requires systemic therapy.
