Positive correlation between breast cancer incidence and HLA antigens.

Abstract

HLA determinations were made at the time of diagnosis among a lot of 141 patients with breast cancer. Values of relative risk as well as frequencies of antigens at the first and the second locus were confronted to data found in a control population. Subdivisions of the neoplastic population according to hormonal status and parity led to the emergence of significant differences: frequency of A28 in menopausal nulliparous women with breast cancer is 26 vs. 7% in controls (p corrected = 0.038) with relative risk = 6.63 (p 0.001).
