Retrospective analysis of the results of radical cystectomy in non-muscle invasive bladder cancer

The results of treatment were analyzed in 53 patients with high-risk non-muscle invasive bladder cancer (BC), who had undergone radical cystectomy (RCE) and bilateral pelvic lymphadenectomy. Histological hypostaging was noted in 20.7% of the patients; 13.2% of them had regional lymph node metastases, which confirms the problems associated with the accurate determination of a BC stage in clinical stage T1. The predictors of lower cancer-specific survival were identified in patients after RCE for pT1 cancer. In our study, 5-and 10-year cancerspecific survival was 90.5 and 88.6% in cT1 stage and 98.2 and 96.3% in pT1 stage, respectively. The findings strongly suggest that RCE can afford a long-term high cancer-specific survival in patients with non-muscle invasive BC.
