CDH3 and neoplasm: A majority of the triple-negative tumours showed basal-like differentiation; 53% (41 of 77) had a core basal profile (BLP4), whereas 64% (49 of 77) of the TNP tumours had positive expression of at least one of the three basal markers (CK5/6, P-cadherin, EGFR) combined with ER– and HER2–, corresponding to the BLP5 profile.
