The purpose of this study was to investigate the relationship between the expression of CD147 and
Lewis y antigen in
epithelial ovarian carcinoma tissues and resistance to chemotherapeutic drugs, and its underlying clinical significance, and to analyze the correlation between the expression of CD147 and
Lewis y antigen. Ninety-two
ovarian cancer patients were divided into a chemotherapeutic-
drug-resistant group (34 patients) and a
drug-sensitive group (58 patients). Immunohistochemical assays were used to measure CD147, and
Lewis y antigen to investigate their correlation with
chemotherapy resistance. Multivariate logistic regression was used to analyze the relationships between risk factors and resistance to
chemotherapy in
ovarian cancer. Cox's model was used to analyze the relationships between risk factors and prognosis. The proportion of tissues expressing CD147 and
Lewis y antigen in the
drug-resistant group were 94.12 and 91.67%, respectively, which were significantly higher than those in the sensitive group (77.59 and 60.34%, respectively). The multivariate analysis indicated that the expression of CD147 and
Lewis y antigen and the pathological stage of the
ovarian cancer were all independent risk factors for drug resistance. Expression of CD147 and
Lewis y antigen was high in the resistant group, and they correlated positively with each other. The expression of CD147 and
Lewis y antigen was significantly higher in the
drug-resistant group and their expression correlated positively in the ovarian epithelium. The expression of CD147 and
Lewis y antigen and the pathological stage of
ovarian cancer were all independent risk factors for drug resistance and prognosis in
ovarian cancer.
