OBJECTIVE: To detect the expression of the protein of TGF-beta1 and E-cadherin in the primary and metastatic lesions of ovarian carcinoma and explore the mechanism of the metastasis of ovarian carcinoma.
METHODS: Immunohistochemistry (IHC) was performed to detect the expression of TGF-beta1 and E-cadherin proteins in primary and metastatic ovarian carcinoma, benign epithelial ovarian tumor and normal ovarian tissue.
RESULTS: The expression of TGF-beta1 was significantly higher in ovarian carcinoma (67.2%) than in benign tumors (28.6%) and normal ovarian tissue (18.9%) (Chi2=26.94, P<0.001), but E-cadherin expression showed a reverse pattern. TGF-beta1 expression in the primary ovarian carcinoma carcinoma was associated with the FIGO stage, lymph metastasis and ascites of the tumor (P=0.01, P=0.01, and P=0.04, respectively). E-cadherin expression in the tumor was associated with the differentiation (P=0.02) and lymph metastasis of ovarian carcinoma (P=0.04). The expressions of TGF-beta1 and E-cadherin were all significantly lower in the primary tumors than in the metastatic tumor (Chi2=4.70, P=0.03; Chi2=5.91, P=0.015). A significant correlation was found between the expressions of the TGF-beta1 and E-cadherin in the primary carcinoma (Kappa value of -0.32, P=0.01).
CONCLUSION: TGF-beta1 and E-cadherin are closely associated with the metastasis of ovarian carcinoma and might be potential targets for controlling the metastasis of ovarian carcinoma.
