ABSTRACT
Objective To explore the correlation between tumor markers including estrogen receptor (ER),progesterone receptor (PR),C-erbB-2 and serum CA125 and MRI findings of endometrial carcinoma(EC).Methods A retrospective analysis of preoperative MRI images of 158 patients with EC was conducted.The expression levels of ER,PR,C-erbB-2,serum CA125 were analyzed with immunohistochemical S-P method and chemiluminescence method.The postoperative pathological results were taken as the gold standard and the relevance between tumor markers and MR signs was analyzed.Results The expression of the four tumor markers were associated with MRI findings of carcinoma staging(P ＜0.05).The expression of ER and PR were negatively associated with the tumor stages by MRI but the expression of C-erbB-2 and serum CA125 were opposite.Conclusion The expression of ER and PR have a high diagnostic value in early endometrial cancer (stage Ⅰ a and stage Ⅰ b) and dynamic detection of C-erbB-2 and serum CA125 can help to predict the metastasis of endometrial carcinoma.
