Abstract
Using an antiserum to epithelial membrane antigen we have screened multiple bone marrow aspirates from 350 patients with primary breast cancer taken at the time of initial surgery. 89 (25%) patients were found to have micrometastases and their presence was related to pathological size (P < 0.01), the presence of peritumoral vascular invasion (P < 0.001), and positive lymph nodes (P < 0.005) but not menopausal status. At a median follow-up of 76 months (range 34–108) 107 patients had relapsed with distant metastases. 48% (43 of 89) of these patients had micrometastases initially compared with 25% (64 of 261) who did not (P < 0.005). The test predicts for relapse in bone (P < 0.01) and other distant sites excluding bone (P < 0.001) and is associated with a shorter overall survival (P < 0.005). We conclude that the detection of micrometastases signals a high likelihood of early relapse and decreased survival in breast cancer.
