Abstract:
Objective:To study the expression of Resistin protein in breast cancer and to evaluate its significance to clinicopathology.Methods:The immunohistochemical technique, EnVision method, was used to evaluate the expression of Resistinin in 42 cases of normal breast tissues and 145 cases of breast cancer, and to analyze the relationship between Resistin protein expression and clinicopathological characteristics and molecular typing of invasive breast cancer patients.Results:The positive rate and strong positive rate of Resistin protein in normal breast tissue were 23.8% (10/42) and 0.0% (0/42) , respectively, while the positive rate and strong positive rate in invasive breast cancer were 88.3% (128/145) and 24.8% (36/145) . The positive rate and strong positive rate of Resistin protein in invasive breast cancer tissues were significantly higher than those in normal breast tissues (both P=0.000) . The positive rate of Resistin protein in invasive breast cancer was significantly higher in estrogen receptor (ER) -negative patients than in ER-positive patients ( P=0.006) , and it was higher in histological grade III and progesterone receptor (PR) -negative subjects than that of I-II and PR-positive, but the difference was not statistically significant ( P=0.053 and P=0.058, respectively) . The strong positive rate of Resistin protein in histological grade III, ER negative, PR negative and human epidermal growth factor receptor 2 (HER2) positive was significantly higher than that in histological grade I-II, ER positive, PR positive and HER2 negative ( P=0.001, P=0.001, P=0.001, and P=0.015, respectively) .The positive rate and strong positive rate of Resistin protein in triple negative breast cancer (TNBC) were significantly higher than those in other breast cancer subtypes ( P=0.048 and P=0.003, respectively) . Conclusion:Resistin plays an important role in the development of breast cancer and is expected to be a potential anti-cancer therapy biologic marker.
