Relationship between the prognosis and expression of estrogen receptor and progesterone receptor in gestational trophoblastic tumor / 西安交通大学学报(医学版)

ABSTRACT

Objective To explore the expression of estrogen receptor(ER) and progesterone receptor(PR) in gestational trophoblastic tumor(GTT) and their significance.Methods The expression of ER and PR in 34 cases of GTT was detected by immunohistochemical method;20 cases of normal villi and 30 cases of hydatiform mole served as controls.Results The positive expression rate of ER in normal villi,hydatiform mole and GTT was 85.00%,83.33% and 44.12%,respectively,and had positive correlation with the malignance degree of GTT.The positive expression rate of PR in normal villi,hydatiform mole and GTT was little.The expression of ER was closely related to these clinicopathological features of GTT(P
