    Abstract:
    The clinical files of 158 patients who were treated by radical cystectomy for infiltrating bladder carcinoma were retrospectively reviewed to define prognostic factors. PATIENTS AND METHODS.--All patients had a radical cystectomy with bilateral pelvic lymph node dissection for an infiltrating operable bladder urothelial tumor. Each tumor was classified according the pTNM staging system and were analysed for the presence of vascular invasion, carcinoma in situ and tumor grade. Twenty-three patients (14.5%) had an irradiation. Sixty-seven patients (42%) received chemotherapy (neoadjuvant in 31, adjuvant in 30, both in 6). RESULTS.--The median overall survival of the whole group was 19 months. The 5 years disease free survival (DFS) and overall survival (OS) were 44% and 31%, respectively. In the univariate analysis, the factors with significant prognostic value were: pT stage and the tumor size for OS, age and lymph node involvement for DFS, presence of carcinoma in situ (CIS) and tumor size for local recurrence free survival (LRFS) and sex and lymph node involvement for metastatic free survival (MFS). The following variables attained significant prognostic value in the multivariate analysis: pT stage and an interaction between lymph node involvement and vascular invasion for OS, pT stage and presence of CIS for LRFS, pT stage for MFS. CONCLUSION.--The pT stage, lymph node involvement and vascular invasion are the most important prognostic factors of survival in infiltrating bladder cancer.
