Prognostic factors of outcome after radical cystectomy for bladder cancer: a retrospective study of a homogeneous patient cohort.
OBJECTIVE
Pathological predictors of outcome for patients undergoing radical cystectomy for bladder cancer are needed as few data are available in the literature. We retrospectively analyzed a homogeneous and contemporary series of patients treated with radical surgery as monotherapy for bladder cancer to identify the independent predictors of survival.


METHODS
We evaluated 369 of 535 patients with bladder cancer treated with radical cystectomy, pelvic node dissection and urinary diversion by the same staff at a single institution between February 1982 and February 1994. Patients treated with radiation therapy and/or chemotherapy, and those who did not undergo formal pelvic node dissection were excluded from study. The end point of univariate and multivariate analyses was the overall 5-year survival.


RESULTS
Univariate analysis revealed that tumor stage, nodal involvement, ureteral obstruction, and vascular, lymphatic and perineural invasion were prognostic predictors of survival (p <0.05). However, only tumor stage (p <0.0000) and nodal involvement (p <0.0000) were independent prognostic variables of survival on multivariate analysis.


CONCLUSIONS
Tumor stage and nodal involvement are the only independent predictors of survival to be used to select the optimal therapy after radical cystectomy, stratify patients in controlled trials and evaluate new prognostic factors.
