Abstract:Objective To explore expression of Galectin-9 in ovarian cancer tissue and correlation with clinical pathological features. Methods 60 ovarian cancer tissues in our hospital from May 2013 to May 2015 were selected as the research group,at the same time,50 cases of benign tumor resection were selected as control group.Expression of Galectin-9 in cancer and benign tumor ovarian tissues were detected by immunohistochemistry method.Relationship between expression of Galectin-9 and clinical pathological features in ovarian cancer tissues was analyzed. Results Galectin-9 was located in the nucleus or cytoplasm.47 cases(94%)was expressed by Galectin-9 in 50 cases of benign ovarian tumor tissues,which was higher than 26 cases(43.33%)in 60 ovarian cancer tissues,with significant difference (P<0.01).Galectin-9 positive expression rate in ovarian cancer tissues with different clinical stages,different pathological grades,and presence of lymph node metastasis was different,with significant difference(P<0.01). Conclusion Galectin-9 expression is low in ovarian cancer tissues,and it is related to pathological grades,lymphatic metastasis and clinical stages,which may be closely related to the occurrence,development and prognosis of ovarian cancer.
