Immunohistochemical analysis of expression of EGFR and HER-2 in GC tissues. (A) Negative expression of EGFR; (B) Positive expression of EGFR was observed in GC. The main staining site was located in cytoplasm; (C) Negative expression of HER-2 in GC; (D) Weak to moderate positive expression of HER-2 in GC; (E) High expression of HER-2 in GC; (F) Strong expression of HER-2 in GC, The main staining site was located in membrane. The cells with brown yellow staining were positive (magnification, ×20). EGFR = epidermal growth factor receptor, GC = gastric cancer, HER-2 = human epidermal growth factor receptor 2.
