Methods Ten cases of normal ovarian tissues and 75 cases of ovarian epithelial neoplasm tissues were detected by immunohistochemical methods: S P for bFGF, FGFR 1,double immunohistochemistry Lab SA for Ki 67 antigen and bFGF. Results The expression level of bFGF, FGFR 1in ovarian epithelium and ovarian epithelial neoplasm showed a step wise increase in the following order:normal <benign <borderline <malignant; The expression level and intensity of bFGF and FGFR 1 were increased with the decrease of differentiation degree and increase of clinical stage in ovarian carcinoma; There was no statistical difference between the expression of bFGF, FGFR 1 in serous cystadenocarcinoma and that of mucinous cystadenocarcinoma; The expression of bFGF was correlated with that of FGFR 1 in neoplastic tissues; There were positive expression rates of bFGF and Ki 67 antigen in ovarian epithelial neoplasm. Conclusion As an important proliferative factor, bFGF plays an important role in carcinogenisis and progression of ovarian epithelial neoplasm.展开更多
