title: Frequent immunohistochemical detection of EGF supergene family members in ovarian carcinogenesis.
abstract: Primary and metastatic ovarian cystadenocarcinomas, carcinomas of low malignant potential (borderline tumors), benign ovarian cystadenomas, and normal ovaries were compared for immunoperoxidase detection of the ligands epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), amphiregulin (AR), cripto, and the receptors, epidermal growth factor receptor (EGF-R), and c-erbB-2. This matrix analysis of these EGF family members indicated no specific pattern of ligand or receptor expression with a specific ovarian histologic category except in the case of AR and TGF-alpha. AR was detected almost exclusively in borderline tumors, suggesting that these tumors may not arise as a pathological continuum between benign cystadenomas and invasive cystadenocarcinomas. Second, the presence of TGF-alpha immunoreactivity in the absence of coexpression of cripto or EGF appeared to be associated only with adenocarcinomas of high grade and stage.
