The prognostic importance of proliferative activity and oestrogen receptor expression in stage I endometrial...

The purpose of this study was to evaluate the prognostic significance of steroid hormone receptor proliferation index in endometrial adenocarcinoma. In this study, the correlation between oestrogen receptor expression, proliferation index and FIGO grade, age, myometrial invasion, tumour size and menopause status was evaluated in 40 patients with endometrial carcinoma. For this purpose, all tumours were stained immunohistochemically with oestrogen receptor and Ki-67 monoclonal antibodies. Oestrogen receptor expression and proliferation indices were found to be statistically associated with grade, age, menopausal status, vascular invasion and tumour size ( p < 0.001). Quantitative assessment of tumour proliferation and expression of oestrogen receptor were found to be important prognostic indicators in endometrial adenocarcinoma.
