An extensive study of the expression of the blood group-related antigen CaMBr1 has been performed by immunohistochemistry, immunoblotting and high performance thin layer chromatography both on frozen and paraffin-embedded (paraffin) samples from normal and neoplastic breast tissues. The glycolipid antigenic fraction (from frozen samples) was preferentially expressed on functioning breast epithelium. In a prospective series of 143 breast cancer cases CaMBr1 expression was associate, on frozen sections, with the transferrin receptor (P = 0.01), the positivity with oestrogen receptor immunochemical assay (P = 0.06), premenopausal status (P = 0.06) and node negativity (P = 0.07). Non-significant correlation with longer disease-free survival (DFS) was observed. In a retrospective series of 862 cases on paraffin sections the glycoproteic antigenic fraction was significantly associated with premenopausal status (P < 0.05) and lobular histotype (P < 0.01), but failed to predict survival, although a trend for longer DFS was observed for positive cases.
