Purpose: We performed a critical analysis of the results of radical cystectomy for invasive bladder carcinoma treated at 1 center.
Materials and methods: Between 1970 and 2000, 2,090 men and 630 women with invasive bladder cancer were treated with 1-stage radical cystectomy and urinary diversion. Followup ranged from 0 to 34.2 years with a mean of 5.5 +/- 5.7. Survival data were correlated to patient and tumor characteristics using univariate and multivariate analysis.
Results: Postoperative mortality was 2.6%. Squamous tumors accounted for 49.4% of cases, transitional cell carcinoma for 36.4% and adenocarcinoma for 9.6%. Regional lymph nodes were involved in 20.4% of cases. The 5 and 10-year disease-free survival rates were 55.5% and 50.03%, respectively. Evidence was provided that tumor stage, histological grade and lymph node status are the only independent variables which affect survival probability.
Conclusions: Contemporary cystectomy can be performed with minimal mortality. Radical cystectomy for organ confined disease is followed by good therapeutic results and enhances the possibilities for functional restoration. With stage progression there is a stepwise reduction in survival probability. The radical operation can provide disease-free survival for an important subgroup of node positive cases (27.3%). Additional therapy is needed to improve the oncological outcome for advanced locoregional disease.
