Immunofluorescence and a new histochemical technique were employed to assay 226 breast cancer specimens for estrogen receptor. Results showed an overall correlation of 91 percent when compared to those of biochemical assays. The histochemical technique is rapid, easy to perform and reveals the same parameters as does immunofluorescence without the need for antiserum. Tumor cell receptor heterogeneity and location of receptor in cytoplasm or nucleus is readily defined by both methods. These histologic tests should prove to be useful in extending the availability of estrogen receptor analysis to all patients with breast cancer.
