[Association of EGFR expression with angiogenesis and chemoresistance in ovarian carcinoma].
To clarify the association of EGFR expression with angiogenesis and chemoresistance in ovarian cancer.Immunohistochemical PV-6000 staining was used to detect the expression of EGFR, LRP protein and MVD in 102 ovarian tumor specimens.EGFR, LRP positive rates and MVD in borderline and malignant ovarian specimens were significantly higher than those in the normal and benign ones (P 0.05). The effective rate of chemotherapy in patients with EGFR and LRP-positive expression were 57.1% and 53.7%, respectively, significantly lower than that in cases with EGFR and LRP-negative expression (85.0% and 90.9%, P < 0.05). In the 64 cases with complete data, the three-year survival rate was 53.0%. The survival time was shorter in the cases with EGFR and LRP-positive expression, poor differentiation, ascites and chemoresistance (P < 0.01), and only LRP-positive expression and chemotherapeutic effect were independently related to survival time (P < 0.05). There was a correlation between EGFR and MVD (r = 0.548, P < 0.01), EGFR and LRP positive expression (P = 0.020).The expression of EGFR in ovarian cancer is related to angiogenesis and chemoresistance. EGFR and LRP-positive expression are related to chemoresistance, and detection of the two proteins may be helpful in guiding chemotherapy choice for ovarian cancer. LRP-positive expression and chemotherapeutic effect may be independent prognostic factors.
