KRT5 and neoplasm: Continuous IHC nuclear score for BRCA1 correlated positively with CK5/6 (r = 0.24, p<0.0001), basal nature of the tumor (r = 0.52, p<0.0001), bcl2 (r = 0.13, p = 0.04), and AR nuclear (r = 0.33, p<0.0001) scores and negatively with age (r = -0.14, p = 0.048) and tumor grade (r = -0.25, p = 0.01) (Table 6).
