title: [Immunohistochemical studies of the determination of the hormone receptor status of breast cancer].
abstract: Immunohistochemical examinations of 89 breast cancer specimens were performed using two different monoclonal antibodies. One marked the nuclear estrogen-receptor (ER) protein (anti-ER, Abbott), whereas the other marked an ER-related cytoplasmic protein (ER-D5 Amersham). Comparison of the results of the biochemical assay with those of the immunohistochemical markers revealed the following correlations: 75% anti ER and 71% ER-D5. Clinical follow-up studies are necessary to specify the relevance of these new immunohistochemical techniques in the anti-hormonal therapeutic management of breast cancer patients.
