PURPOSE: Multivariate analysis of prognostic factors influencing survival and bladder preservation after radiochemotherapy for bladder cancer following transurethral resection of the bladder (TURB). PATIENTS AND METHODS: At the University Hospital of Erlangen 333 patients with bladder cancer were treated with either radiotherapy alone (RT, n = 128) or platin based radiochemotherapy (RCT, n = 205) after TURB between 5/1982 and 5/1996. Two-hundred and eighty-two curative patients, with either muscle invasive or T1-high risk cancer, were analyzed. Median age was 66 years, median follow-up is 7.5 years. Uni- and multivariate analysis was performed for age, grade, R-status after initial TURB, T-category and treatment modality relevant to the endpoints initial response, survival and bladder preservation. RESULTS: Treatment related mortality was below 1%. Complete remissions were achieved at 57%, 70%, and 85% after RT or RCT with carboplatin or cisplatin. This difference was multivariately significant. Further significant prognostic factors were pT-category and R-status. For all patients survival was 59% and 43% after 5 and 10 years. 79% of survivors could keep their own bladder. Five-year survival rates after RT alone, RCT with carboplatin or cisplatin were 47%, 57%, and 69%, respectively. This was univariately significant. The only multivariately significant factor for survival and bladder preservation was the R-status after initial TURB. CONCLUSIONS: Treatment of bladder cancer by TURB and RT/RCT is an alternative to primary cystectomy. The addition of chemotherapy leads to significantly more complete remissions and better survival. Initial TURB is recommended to be as radical as possible.
