EPİTELYAL OVER TÜMÖRLERİ İLE bcl-2, nm 23 ve c-erbB-2 EKSPRESYONLARI ARASINDAKİ İLİŞKİ

Background and Design.- Ovarian cancer is the most common cause of death among all gynecologic malignancies. Genetic alterations important in ovarian tumorigenesis have been identified recently. Ovarian tumors are the end result of a complex pathway involving multiple oncogenes and tumor suppressor genes. The aim of this study was to investigate the value of nm 23, bcl-2 and c-erbB-2 expressions in epithelial ovarian tumors. We studied 102 patients with benign, borderline and malignant epithelial ovarian tumor. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded specimens. The expression of nm 23, bcl-2 and c-erbB-2 gene products were investigated immunohistochemically in ovarian carcinomas, borderline and malignant neoplasms.Results.- Significantly more immunoreactivity with bcl-2 protein was present in benign tumors compared to borderline and malignant tumors (p
