Purpose: To describe the incidence and management of patients who develop a prostatic urethral (PU) urothelial carcinoma recurrence after Bacillus Calmette-Guerin (BCG) induction for non-muscle invasive bladder cancer (NMIBC)., Materials and Methods: We performed a retrospective cohort study of all patients who received BCG induction at our institution from 1996 to 2021 (N = 642) for NMIBC. All patients with pathologically confirmed PU involvement following BCG induction with no known PU involvement pre-BCG were included. We describe the presentation, management, and outcomes for PU recurrence., Results: Among the 642 patients, 21 (3.3%) patients had a PU recurrence after BCG induction. 8 (38%) patients received >2 cycles of BCG induction prior to the recurrence. Median time from induction to PU recurrence was 21 months and 12 (57.1%) patients had concurrent bladder recurrence. At the time of their PU recurrence, 14/21 (67%) of patients were deemed BCG Unresponsive. Nearly all (18/21) were high grade, and 10 were stage Tis, 7 Ta, and 3 T1, and 1 T2. 19/21 (90%) patients received bladder sparing treatment: 6 with TURBT and BCG, 6 with TURBT and intravesical chemotherapy, 5 with TURBT only, and 2 did not receive immediate treatment of their PU recurrence due to advanced stage of disease. 2/21 (9.5%) received a radical cystectomy for initial treatment of the post-BCG PU recurrence, of which all were >pT2. Median follow-up time from BCG induction to the patient's last visit was 64.5 months. Following treatment of PU recurrence, 15/18 patients had another recurrence at a median of 5 months: about 47% of recurrences were bladder only and 14% recurred only in the PU as well. About 1 patient received a RC after the second recurrence and was pT2., Conclusion: Patients with PU recurrences following intravesical BCG have a high-risk disease phenotype with a significant risk of recurrence. Conservative management may be appropriate for well-selected patients who do not desire a cystoprostatectomy., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Purpose: While radical cystectomy (RC) is the standard of care for muscle invasive bladder cancer (MIBC), partial cystectomy (PC) is an effective alternative in select patients. We sought to examine differences in survival for RC and PC in a hospital-based registry., Material and Methods: We identified patients diagnosed with cT2-4 bladder cancer who underwent RC or PC from 2003 to 2015 in the National Cancer Database (NCDB). Using inverse probability treatment weighting (IPTW) to control for known confounders, we compared the primary outcome of overall survival (OS) in patients who underwent RC vs. PC. Kaplan-Meier survival analysis, univariable and multivariable Cox proportional hazards modeling were used. We performed a secondary survival analysis for a subcohort of patients with cT2, cN0, tumor size ≤5 cm, and no concurrent carcinoma in situ (CIS), who may be optimal candidates for PC., Results: A total of 22,534 patients met inclusion criteria, of which 6.9% (1,457) underwent PC. RC had longer median OS than PC (67.8 vs. 54.1 months) and on Cox regression analysis (HR 0.88, 95% CI, 0.80-0.95, P = 0.002). However, in our subcohort, there was no difference in OS between RC and PC (HR 1.02, 95% CI, 0.9-1.2, P = 0.74). PC was associated with increased time from surgery to any systemic therapy or death in the subcohort., Conclusions: Among patients with clinically organ-confined MIBC, PC appears to afford similar survival outcomes to RC in a large national data set. The safety and tolerability of PC may warrant consideration in highly selected patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Purpose: Partial cystectomy (PC) is a bladder sparing option to treat bladder cancer in a carefully selected group of patients. We sought to analyze outcomes of partial cystectomy (PC) in a contemporary cohort of patients at a single institution., Material and Methods: Records were reviewed for 43 patients with a primary urothelial carcinoma (UC) who had a partial cystectomy with curative intent at Columbia University Medical Center from 2004 to 2019. Endpoints of interest were noninvasive recurrence (defined as any recurrent nonmuscle invasive disease), advanced recurrence (defined as a muscle invasive recurrence or metastasis), and death. We used unadjusted Cox proportional hazards regressions and log rank tests to estimate the association between clinical characteristics and endpoints of interest., Results: Among 43 patients with bladder cancer treated with partial cystectomy, median patient age was 73 years (interquartile range 67-77.5) and 86% were male. Twenty-three percent of patients received preoperative neoadjuvant chemotherapy (NAC) and 49% of patients were given perioperative intravesical chemotherapy at the time of PC. Pathologic stage was
