The samples were classified according to the PAM50 intrinsic subtypes used for invasive breast cancer (IBC), which identified Basal (N = 5), Luminal A (N = 10), Luminal B (N = 6), Her2-like (N = 7), and Normal-like (N = 10) samples (Fig. 1d). This evidence concerns the gene ERBB2 and inflammatory breast carcinoma.
