    Abstract:
    The aims of this paper are to demonstrate the stainability of estrogen, CEA, and ferritin in breast carcinomas, fibroadenomas, and fibrocystic diseases; to examine whether the findings of endogenous estrogen using the immunohistochemical detection method are related to estrogen receptor (ER) assays; and to determine whether the stainability of estrogen, CEA, and ferritin were related to the prognosis of breast carcinomas. In breast cancer, the stainability of estrogen using the peroxidase-antiperoxidase (PAP) method was positively correlated with the dextran-coated charcoal (DCC) assay for ER. In breast cancers, the percentage of positive staining was 46% for estrogen, 48% for CEA, and 47% for ferritin. With all three stains, significant differences were observed between cancer and benign diseases. Cases that were both positive for estrogen staining and negative for CEA showed a good prognosis after the recurrence of disease. Our data suggest that the immunohistochemical staining of estrogen, CEA, and ferritin might predict the biological behavior of breast carcinomas and be a prognostically useful indicator of breast cancer patients.
