Abstract:Objective: To evaluate the association of serum adiponectin concentration with breast cancer risk in Chinese Han women. Methods:Related papers about the association of serum adiponectin concentration with breast cancer risk in Chinese Han women published between 1995 and 2012 were retrieved and evaluated. Data were reanalyzed by Meta analysis. Results:A total of eight studies that meet the inclusion/exclusion criteria were included. Data from 481 cases of breast cancer and 346 healthy control subjects were analyzed. The results showed,① Patients with breast cancer had lower serum adiponectin values than healthy controls(P<0.05, WMD=-2.412,95%CI-3.173 to-1.651). Among premenopausal women, patients with breast cancer also had lower serum adiponectin values than healthy controls(P<0.05,WMD=-1.884,95%CI-2.770 to-0.998).② Compared with patients without lymph node metastasis, patients with lymph node metastasis had significantly lower serum adiponectin levels(P=0.002,WMD=-1.981,95%CI-3.238 to-0.724). Conclusion: Lower adiponectin concentration could be a risk factor of breast cancer and a predictor of poor prognosis.
