[Survival of patients with infiltrating tumors of the bladder treated with cystectomy].

We reviewed the results of infiltrating bladder cancer treated by radical cystectomy to evaluate survival. Between January 1989 and December 1992, a total of 58 consecutive cystectomies or anterior pelvectomies performed on 48 men and 10 women (mean age 63.2 years) in our department were retrospectively evaluated. Four patients were lost to follow-up and the mean follow-up was 72 months. Pathologic staging was as follows: stage pT0,A,1: 13.5%, stage pT2: 17.5%, stage pT3a: 12%, stage pT3b: 36%, stage pT4: 21%. The year probability of the overall survival was 60% for p T2-p T3a patients, 15% for pT3b patients, and 9% for pT4 patients, respectively. Overall, 53.5% of patients died of cancer, 7.5% of intercurrent disease, and 39% were alive. The cancer related death rate was 12% for pT2-pT3a patients, and 82% for pT3b-pT4 patients. The 5- year probability of specific survival was 80% for pT2-pT3a patients, 15% for pT3b patients, and 9% for pT4 patients, respectively. Infiltrating bladder cancer still has a high mortality rate. Radical cystectomy may be considered to be a curative procedure for stages pT2 and pT3a. Adjuvant chemotherapy and/or radiotherapy seem necessary at stages pT3b and pT4. Preoperative criteria need to be better defined to reduce understaging.
