ERBB2 and carcinoma: The frequency of diploid/CIN- tumors was higher in the luminal A carcinomas than in luminal B (HER2-), luminal B (HER2+), HER2, and basal-like carcinomas (P = 6.315×10-4, P = 2.690×10-12, P = 5.133×10-11, and P = 3.823×10-8 between luminal A subtype and luminal B (HER2-), luminal B (HER2+), HER2, and basal-like subtypes, respectively) (Figure 3).
