ADAM33 and breast carcinoma: Here, we compare clinicopathological information and the expression of a panel of IHC markers (ER, PR, HER2, EGFR, CK 5/6, CK14, CK17, c-Kit and Ki67) with the ADAM33 protein scores to determine whether ADAM33 protein is clinically efficient as a prognostic or predictive marker for breast cancer.
