CDH3 and carcinoma: As previously reported, P-cadherin expression was significantly associated with high-grade carcinomas (p < 0.0001), HER2-overexpressing and basal-like molecular subtypes (p < 0.0001), ER and PgR negativity (p < 0.0001), high expression of HER2 (p < 0.0001), as well as with high Ki67 (p = 0.0141).
