We developed an immunoperoxidase technique using a monoclonal antibody to the estradiol receptor (ER) to identify immunoreactive ER (iER) in breast carcinomas and compared this with the conventional dextran-coated charcoal (DCC) steroid binding assay. We also examined the relationship between the iER and response to therapy in patients with advanced breast cancer. We found iER-positive cells in 60 of 90 carcinomas (66.7%); this correlated with the DCC assay (r = 0.76; P less than .001). Of these, 56 patients were found to be assessable for response to endocrine therapy. Twenty-two showed an objective response to some form of endocrine manipulation, and all these had positively stained carcinomas. By deriving a staining intensity index (SII) we observed that 21 of 22 responders (95%) had an SII of greater than or equal to 0.5, whereas only 8 of 34 nonresponders (24%) had an SII of greater than or equal to 0.5. This difference is highly significant (P less than .001). None of the 17 patients with negatively stained carcinomas responded to endocrine therapy. We conclude that the monoclonal antibody to ER can help identify breast cancer patients who may respond to endocrine therapy.
