ERBB2 and neoplasm: For the GSTP1 andCCND1 genes there was no statistically significant differenceamong the CNAs observed and their distribution according to the IHC (Luminal, TNBCand HER2) defined tumor subtypes (χ22=2.44; P>0,20 p=0.1130and χ22=0.43; P>0.80 p=0.3092 andχ22=5.79; P>0.05, respectively) (Figure 1).
