Abstract:
In this study, we analyzed EGFR, HER2/neu and Ki67 immunoexpression for 26 benign, borderline and malignant serous ovarian tumors. EGFR and HER2/neu immunoreactions were present in some benign/borderline tumors with high/low intensity of immunostain. In poorly differentiated adenocarcinomas, the EGFR/HER2/neu reaction was intense compared to well-differentiated ones. The Ki67 medium proliferation index was 2.1% for benign tumors, 6% in the borderline and 47.7% in malignant tumors. EGFR, HER2/neu and Ki67 can be used to identify benign/borderline tumors with progression potential and the malignant aggressive tumors.
