Correlation of estrogen and progesterone receptors ER and PR expression with the growth of endometrial cancer

摘要

Objective:To study the correlation of estrogen and progesterone receptors ER and PR expression with the growth of endometrial cancer.Methods: A total of 80 patients with endometrial cancer who were treated collected in the Fourth People''s Hospital of Shaanxi and the First Affiliated Hospital of Xi''an Jiaotong University between January 2013 and January 2017 were collected, endometrial cancer tissue and para-carcinoma normal tissue were collected, immunohistochemical method was used to detect positive expression of ER and PR, and fluorescence quantitative PCR was used to detect the mRNA expression of proliferation and apoptosis genes.Results: The positive expression of ER and PR in tumor tissue were significantly lower than those in para-carcinoma tissue;proliferation genes KCC1, RRM2, SRPX2 and Snail mRNA expression in tumor tissue of ER-positive group and PR-positive group were lower than those of ER-negative group and PR-negative group;anti-apoptosis genes Wip-1 and Bcl-2 mRNA expression were lower than those of ER-negative group and PR-negative group respectively while pro-apoptosis genes Bid, Bax and Fas mRNA expression were higher than those of ER-negative group and PR-negative group respectively.Conclusion:Patients with positive expression of endometrial estrogen and progesterone receptors ER and PR are with lower tumor proliferation activity, higher apoptosis activity and lower malignant degree than patients with negative ER and PR expression.
