The authors evaluated the ability of a monoclonal antibody immunoperoxidase procedure (ERICA [Estrogen Receptor Immunocytochemical Assay], information from Regulatory Affairs Department, Abbott Laboratories, North Chicago, IL) to detect estrogen receptor in aspiration biopsy cytology (ABC) specimens from breast cancer routinely taken by fine-needle aspiration during office diagnostic evaluation. Results were correlated with biochemical values determined from dextran-coated charcoal (DCC) assay on tumor tissue obtained subsequently at operation. ERICA had positive results in 32 of 41 DCC-positive cases (sensitivity, 78%) and in 5 of 17 DCC-negative cases (specificity, 71%). The semiquantitative degree of ERICA positivity correlated with the concentration of estrogen receptor by DCC. Results of both assays correlated with the histologic grade of the tumor and patient age. Estrogen receptor can be determined by immunocytochemistry in ABC specimens in a community hospital. However, the sensitivity and specificity of this procedure compared with biochemical assay, and eventual response to hormonal therapy, require further investigation.
