Abstract
Purpose: We study the incidence and pattern of upper tract recurrences following radical cystectomy for bladder cancer, and analyze the prognostic factors. Materials and Methods: 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. Results: 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). Conclusions: 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.
