The use of human mammary epithelial antigens (HME-Ags) was explored in detection of human breast cancers. Specific antibodies were made against HME-Ags, which are normal differentiation antigens of human breast epithelium, and were used in a solid phase radioimmunoassay. Circulating HME-Ags were detected in sera of breast cancer patients with high-tumor load. These antibodies, after radioiodination, were also successfully used to localize human breast tumors grafted in athymic nude mice by whole body radioimaging devices. These results suggest that HME-Ags can be applied to breast cancer diagnosis with higher specificity than those already reported.
