Abstract:Objective To explore the expression of estrogen receptor (ER), progesterone recetor (PR), P-glycoprotein(P-gp), glutathione-s-transferases π (GST-π) and P-glycoprotein Ⅱ (Topo Ⅱ) in breast cancer. Methods A total of 91 cases of specimens of breast cancer diagnosed by pathology after surgical excision in Huai′an Maternal and Child Health Hospital from September 2010 to January 2014 were selected. The expression of ER, PR, GST-π, P-gP, TopoⅡin 91 patients from breast cancer tissues were detected by immunohistochemistry technique. Results The expression of ER, PR, GST-π, Topo Ⅱwere significantly associated with histological grades, there existed correlation between Topo Ⅱand lympnode metastasis, P-gP expression was significantly associated with tumor size. The expression of ER was positively correlated with the expression of PR (r=0.637, P=0.000). Conclusion The detection of the expression of ER, PR, GST-π, P-gP, Topo Ⅱhave important meaning for assessing the prognosis of patients with breast cancer and chemtherapy options.
