ABSTRACT
PURPOSE:
We investigated the influence of positive pre-cystectomy biopsies of the prostatic urethra in males and the bladder neck in females on urethral recurrence, cancer specific and overall survival, and functional outcomes after orthotopic bladder substitution. MATERIALS ANDMETHODS:
We retrospectively analyzed the records of 803 consecutive patients, including 703 males and 100 females, who underwent orthotopic bladder substitution as well as pre-cystectomy biopsy of the prostatic urethra in males and the bladder neck in females, at our institution between April 1986 and December 2017.RESULTS:
Pre-cystectomy biopsies were negative in 755 of the 803 patients (94%) (group 1) and positive in 48 (6%) (group 2). Biopsies in group 2 revealed carcinoma in situ in 35 of the 48 cases (73%), pTaG1/G2 in 5 (10%) and pTaG3/pT1G3 in 8 (17%). Median followup was 64 months (IQR 21-128). At a median followup of 56 months (IQR 18-127) urethral recurrence developed in 45 of the 803 patients (5.6%), including 30 of the 755 (4%) in group 1 and 15 of the 48 (31.3%) in group 2 (p <0.001). Only 10 of the 45 patients (22%) with urethral recurrence required salvage urethrectomy while locally conservative treatment was successful in 27 (60%). Of the remaining 8 patients 6 of 45 (13%) underwent synchronous palliative chemotherapy and 2 of 45 (4%) refused treatment. Multivariate regression analysis revealed a higher risk of urethral recurrence if patients had positive pre-cystectomy biopsies (group 2 HR 6.49, 95% CI 3.33-12.62, p <0.001) or received neoadjuvant or adjuvant chemotherapy (HR 3.05, 95% CI 1.66-5.59, p <0.001). Cancer specific and overall survival as well as functional outcomes were similar in the 2 groups.CONCLUSIONS:
Positive pre-cystectomy biopsies prior to orthotopic bladder substitution increased the urethral recurrence rate but did not lower cancer specific or overall survival. Most urethral recurrences were managed successfully by local treatment. Orthotopic bladder substitution is an option in highly selected patients with positive, noninvasive pre-cystectomy biopsies, provided that they undergo regular followup including urethral cytology.Palavras-chave
