Abstract

BACKGROUND:Carcinoma of the endometrium is the most common gynecologic malignancy in developed countries. Estrogen and progesterone receptors are present in most cases of endometrial adenocarcinoma of endometrioid type, with low-grade tumors being almost invariably positive.OBJECTIVE:Evaluation of estrogen and progesterone receptors expression in endometrial carcinoma and their correlation with age, grade and stage of tumor.MATERIALS AND METHODS:This is a retrospective study using data collected form archived materials from Teaching Laboratories of Baghdad Medical City ,the period of the study (from February 2020 to December 2020) including formalin fixed, paraffin embedded tissue blocks. Three sections of 5µm thickness were taken from each block, the first was stained with (H&E) for histological revision, the second section was stained for ER and the third section was stained for PR to determine the signal specificity.RESULTS:Twenty five cases of endometrial adenocarcinoma were studied. In this study, the peak incidence of endometrial carcinoma was found to be in the range of (61-70) years old. Most cases showed grade I (40%) and grade II (44%). Seventy two percent were positive for estrogen receptor and (60%) of all tumors reacted positively for progesterone receptor. Co-expression of both estrogen receptor and progesterone receptor were noted in (52%) of cases.CONCLUSION:Majority of cases with endometrial carcinoma were found to be of grade I and grade II (low grade) and confined to the uterus (stage I & II) at time of diagnosis and most of them express ER and PR and half of the cases express both.
