Hormone Receptor Expressions and Proliferation Markers in Postmenopausal Endometrial Polyps

Abstract

Estrogen may have a role in the development of postmenopausal endometrial polyps, either by direct stimulation of localized proliferation or by stimulation of proliferation via other pathways, such as activation of Ki67 or through inhibition of apoptosis via bcl-2. c- erbB-2 is unlikely to play any role in development of these lesions.
