OBJECTIVE: To evaluate long-term survival after radical cystectomy (RC) for bladder cancer (BC) and to define risk factors for BC-specific death.
MATERIAL AND METHODS: Patients having RC for BC with curative intent in Turku University Hospital 1986-2005 were assessed. Survival results were recorded and 10 risk factors for BC-specific death were analysed.
RESULTS: In total, 248 patients with a median age of 64 years were included in the study. Sixty-four per cent of the tumours were intravesical and the lymph-node metastasis rate was 9%. Disease recurrence was observed in 90 patients (36%). Median time for local recurrence and distant metastasis after RC was 9 and 12 months, respectively. The mortality rate for both local recurrence and distant metastasis was 93%. Upper urinary tract and urethral recurrences were less common (3% and 5%, respectively) and occurred later (median time to recurrence 26 and 18 months, respectively). The 5-, 10-, and 15-year BC-specific survival was 69%, 67% and 66%, respectively. Extravesical tumour status, high tumour grade, positive node status and no history of intravesical therapy before RC were significant risk factors for BC-specific death. Other variables (neoadjuvant radiation, lymphadenectomy, age, time period, gender, smoking) did not affect the risk.
CONCLUSIONS: The survival results are comparable with those of high-volume centres and demonstrate the possibility of excellent local control in all cases and a high rate of cure in tumours confined to the bladder. Extravesical tumour growth, high grade and lymph-node metastasis are the most important risk factors for BC-specific mortality.
