Abstract:
Platelet-derived endothelial cell growth factor (PD-ECGF) is an angiogenic factor and in some studies PD-ECGF/dTdRPase expression levels in several kind of cancers were higher than in their surrounding normal tissues. In this study, we evaluated PD-ECGF/dTdRPase expression in bladder cancer by an immunohistological method and determined whether it correlated with tumor stage, grade and recurrence. PD-ECGF/dTdRPase expression was correlated with tumor grade and stage. Furthermore, among the superficial tumors, PD-ECGF/dTdRPase expression was correlated with a recurrence-free rate and thus it might be a prognostic factor for the recurrence of superficial bladder cancer.
