Radical cystectomy for carcinoma of the bladder: critical evaluation of the results in 1,026 cases

Abstract

Purpose: We performed a critical analysis of the different prognostic factors affecting survival among patients with carcinoma of the bladder for whom cystectomy was indicated. The different patient and tumor characteristics were correlated to survival data by a univariate as well as multivariate analysis.

Materials and methods: Between 1969 and 1990, 764 men and 262 women, average age plus or minus standard deviation 43 +/- 8 years, with invasive carcinoma of the bladder were eligible for 1-stage radical cystectomy and urinary diversion. Patients were followed regularly and examined signs for and location of treatment failure. Followup ranged from 0 to 24.2 years, with a median plus or minus standard deviation of 4.05 +/- 4.16 years.

Results: Postoperative mortality was 4%. Most of the patients presented with advanced stage (greater than P3) disease. Squamous tumors accounted for 59% of cases, transitional carcinoma 22% and adenocarcinoma 11%. Bilharzial eggs were seen in 85% of the specimens. Regional lymph nodes were involved in 18.3% of the cases. The 5-year survival rate was 48%. The survival estimate was correlated to patient and tumor characteristics by univariate and multivariate analyses. Only tumor stage and grade, and lymph node status had a significant impact on survival.

Conclusions: Contemporary cystectomy with continent diversion for muscle invasive disease provides minimal morbidity, offers good locoregional disease control and results in acceptable quality of life. The presence of positive regional lymph nodes is not a contraindication to this therapy.
