(A) Before chemotherapy; (B) after chemotherapy of the same patient, staining of the breast carcinoma (ductal carcinoma) tissues immunohistochemically (magnification, ×200) after the neoadjuvant chemotherapy; (C) the ERβ expression level in the breast carcinoma tissues of the patient is significantly decreased, showing statistical significance (P<0.05).
