Abstract:
Objective To detect and analyze the expression of ER and PR in endometrial benign and malignant tumor,and to study its correlation of ER and PR with the establishment and development of endometrial carcinoma.Methods The expressions of ER and PR were examined by immunohistochemical method in 58 eases of endometrial carcinoma,37 cases of atypism endometrial hyperplasia,25 cases of simple endometrial carcinoma.and 25 eases of normal endometrium.Results The expressions of ER and PR were higher in normal endometrium,atypism endometrial hyperplasia and endometrial carcinoma.They were lower in endometrial carcinoma than in atypism endometrial hyperplasia,both were higher than that in normal endometrium(P＜0.05).The rates of expression in ER and PR increased gradually from histological grade Ⅰ,Ⅱto Ⅲ.The expressions of ER and PR in histological grade Ⅰ were significantly different from that in histologic grade Ⅲ(P＜0.05).There were no correlation between expressions and ages,which expression rates less than 50 years were higher than those above 50 years.Its expression W88 not related to different clinic grade(P＞0.10).Conclusion The expressions of ER and PR increased gradually from normal endometrium,atypism endometrial hyperplasia to endometrial carcinoma.ER and PR expressions were obviously related to histologic degree.It maybe related to establishment and development of endometrial carcinoma.
