Prognostic significance of p53, bcl-2 and Ki-67 in high risk superficial bladder cancer.

Abstract

The Ki-67 proliferative index has an independent validity in predicting those patients with high risk superficial bladder tumors who may recur in a short follow-up period. A similar relationship of Ki-67 overexpression to progression was not detected. The expression of p53 and bcl-2 does not seem to offer any prognostic information in predicting either recurrence or progression over the prognostic factors that are currently used in clinical practice.
