The prognostic significance of the immunohistochemical expression of P53 and BCL-2 in endometrial cancer

Abstract

The objective of this study was to verify the frequency of P53 and BCL-2 immunohistochemical expression in 98 patients with endometrial carcinoma, and to correlate it with clinical stage and patient survival. A significant difference was found regarding the frequency of P53 expression when comparing type I and II tumors (23.7% and 54.5%, respectively; p = 0.006). A positive correlation was observed between P53 immunoexpression and patient survival in type I and II tumors (p = 0.009 and p = 0.036, respectively). BCL-2 expression was significantly more frequent in early clinical stages in both types of endometrial cancer (p < 0.001 and 0.002) and correlated with a decrease in overall survival in type I endometrial cancer (p = 0.014). Thus, the prognostic value of these biomarkers in endometrial cancer needs to be further investigated. © Polish Society for Histochemistry and Cytochemistry Folia Histochem Cytobiol. 2011.
