Abstract:
Objective:To study the expressions of P-gp、GST-?、TopoⅡin breast carcinoma and the relationship between the drug resistance-associated proteins and the sensitivity of neoadjuvant chemotherapy of breast carcinoma.Methods:Eighty specimens of breast carcinoma were collected and the patients were classified randomly into group A and group B.Neoadjuvant chemotherapy(CEF)was used in group A,and we respectively measured maximum diameters of the tumors by B-ultrasound examination before and after the chemotherapy.we measured the expression of P-gp、GST-?、TopoⅡin 80 specimens by immunohistochemical technique(S-P).Results:The expression of P-gp increased significantly in group A compared with group B(P
