Abstract

ABSTRACTAims of the study: To evaluate the expression of the Bcl-2 oncoprotein in patients with primary breast cancer, to correlate it with estrogen and progesterone receptors and various prognostic parameters.Patients and methods: Fifty two cases of primary breast cancer in which the estrogen and progesterone receptors statuses were previously tested by immuno-histochemical staining, were included in this retrospective study. The cases were collected from Al- Jamhori Teaching Hospital, Nineveh Private Hospital and Private laboratories. The expression of Bcl-2 oncoprotein was evaluated immunohistochemically; the findings were correlated with the estrogen and progesterone receptors, the age of the patients, size, type and grade of the tumor, lymph node status and vascular invasion.Results: Bcl-2 oncoprotein was detected in 24 cases of primary breast cancer (46.2%). In this study the majority of estrogen and progesterone receptors positive cases, (87.5%) and (83.3%) respectively, showed positive Bcl-2 oncoprotein expression, (P
