Upper tract recurrences following radical cystectomy: an analysis of prognostic factors, recurrence pattern and stage at presentation.

Abstract

We study the incidence and pattern of upper tract recurrences following radical cystectomy for bladder cancer, and analyze the prognostic factors. A retrospective study was performed on 529 patients who underwent radical cystectomy and urinary diversion at Memorial Sloan-Kettering Cancer Center between July 1989 and June 1997. Data related to upper tract recurrence were analyzed. Of the 529 patients 16 (3%) had upper tract recurrence. Median followup was 16.9 months for the entire group and 49.1 months for patients with upper tract recurrence, with a median time to recurrence of 37.2 months. Of 12 upper tract recurrences 7 (58%) were locally advanced at surgery (p3a or greater with or without lymph node metastasis) and 5 of 16 patients with recurrence (31.3%) had bilateral tumors (2 synchronous and 3 metachronous). Overall survival from the time of diagnosis of upper tract recurrence after radical cystectomy was poor, with a median of 10 months (confidence interval 1 to 19). The incidence of upper tract recurrence following radical cystectomy is low (3%). However, the incidence of bilateral tumors (31.3%) and locally advanced stage at the time of operation (58%) is higher than expected for upper tract tumors in the general population. Survival of patients with upper tract recurrence is poor, with a median of 10 months.
