The Expression and Clinical Significance of sTn in Endometrial Carcinoma / 天津医药

ABSTRACT

Objective To investigate the expression and clinical significance of tumor-associated carbohydrate anti-gen sTn in endometrium from patients with atypical hyperplasia of endometrium, endometrial carcinoma and benign the uter-ine lesion. And to analyze the association between sTn and the pathologic stage and grade of endometrial carcinoma. Meth-ods sTn was detected by immunohistochemistry in 193 patient samples, including 93 subjects with endometrial carcinoma, 50 subjects with atypical hyperplasia of endometrium and 50 subjects with benign uterine lesions. Results The positive sTn rate in endometrial carcinoma group was 73.1%,which was significantly different from that in atypical hyperplasia endo-metrium group (32%) and that in benign uterine lesion group (14%), (P＜0.017). sTn positive rate in patients with endometri-al carcinoma was 78.8%which is higher than that in patients with other diseases (P＜0.008 ). The positive rate of sTn in pa-tients with poorly differentiated endometrial carcinoma was significantly higher than that in patients with highly differentiat-ed endometrial carcinoma (P＜0.017). The positive rate of sTn in tissues of tumor infiltration with depth of more than half of myometrial was significantly higher than in tissues of tumor infiltration with depth of equal or less than half of myometrial (P＜0.05). But there was no significant difference in sTn positive rate between the endometrial carcinoma groups with and without lymph node metastasis (P>0.05). Conclusion sTn may play a role in the tumorigenesis and development of endo-metrial carcinoma.
