Reproductive organ involvement in female patients undergoing radical cystectomy for urothelial bladder cancer

Abstract

Purpose: We evaluated pathological involvement of the reproductive organs in a cohort of female patients treated with anterior pelvic exenteration for invasive urothelial carcinoma of the bladder.

Materials and methods: A total of 2,098 patients with bladder cancer underwent cystectomy at our institution between 1971 and 2008, including 458 females, of whom 411 had urothelial carcinoma of the bladder. Median followup was 12.2 years (range 0.1 to 35.5). We reviewed the clinicopathological features of female patients treated with cystectomy who had pathological reproductive organ involvement. Recurrence-free and overall survival is reported using Kaplan-Meier survival curves.

Results: Of 411 patients with urothelial carcinoma of the bladder 267 underwent reproductive organ removal with cystectomy. A total of 20 patients (7.5%) had reproductive organ involvement, including 10 (3.8%) with vaginal, 2 (0.7%) with cervical and 1 (0.3%) with uterine involvement only, while the remaining 7 (2.6%) had multiple reproductive organs involved. Median age was 71 years. Clinical stage T4a was diagnosed in 25% of cases. A palpable mass, hydronephrosis (each p <0.001) and positive lymph nodes at anterior pelvic exenteration (p = 0.001) were associated with reproductive organ involvement. Recurrence developed in 14 patients (70%) at a median of 7 months (range 1 to 22). Five-year recurrence-free and overall survival rates were 14.9% and 8.8%, respectively.

Conclusions: The risk of reproductive organ involvement in female patients who undergo anterior pelvic exenteration for urothelial carcinoma of the bladder was about 7.5% with the vagina the most commonly involved organ. A palpable mass and hydronephrosis were among the preoperative clinical factors associated with reproductive organ involvement. The prognosis is poor in patients with reproductive organ involvement.
