Triple negative breast cancers (TNBCs), which account for approximately 15% of all breast cancers, are characterised by a lack of ERα, PR expression and HER2 overexpression, and although the majority of TNBCs share similar gene expression profiles with Basal-Like Breast Cancers (BLBCs), there is not complete overlap between the two groups [3]. This evidence concerns the gene ERBB2 and breast carcinoma.
