Apoptotic and proliferation indexes in primary superficial bladder tumors

Abstract

Whether apoptotic index [AI] and/or Ki-67 labeling index [Ki-67LI] add prognostic information in bladder cancer remains unclear. Mean AI and Ki-67 LI increased with grade and stage in 147 superficial bladder tumors. AI (>1.7%) correlated with tumor size, grade and proliferation. Ki-67 LI (>10%) correlated with higher grade and stage. Tumor size and Ki-67 LI were independent predictors of disease-free and progression-free survival, respectively. Tumor size, patient's age and tumor's recurrence predicted overall survival. We conclude that conventional clinical parameters and Ki-67 LI define risk groups of bladder tumors, while AI has limited value.
