Abstract: ObjectiveTo quantitatively examine the relationship between xeroderma pigmentosum complementation C group (XPC) rs2228000(C/T) polymorphism and the susceptibility of breast cancer. MethodsThe relevant casecontrol studies published up to December 2015 which investigated XPC rs2228000(C/T) polymorphism and breast cancer risk were identified by searching PubMed, Cochrane Library, Chinese Biomedical Literature Data, Wanfang Database, China National Knowledge Infrastructure and VIP Database. Metaanalysis was conducted using STATA 12.0 software and odds ratio (OR) with its 95%CI were estimated. ResultsA total of 8 researches involving 9 casecontrol studies (3 850 breast cancer cases and 5 047 healthy controls) were included. The Metaanalysis showed that there was statistical association between XPC rs2228000(C/T) variance and breast cancer risk in the homozygous model (TT vs. CC: OR=1.28, 95%CI: 1.081.52, Z=2.80, P=0.005) and recessive model (TT vs. TC+CC: OR=1.23, 95%CI: 1.051.43, Z=2.64, P=0.008), but not in the allele model, heterozygote model and dominant model. In the subgroup of ethnicity and genotyping methods, the different significant correlation was existed between them under Asian and PCRRFLP in genetic models (T vs. C: OR=1.21, 95%CI: 1.051.40, Z=2.63, P=0.009; TT vs. CC: OR=1.55, 95%CI: 1.132.13, Z=2.70, P=0.007; TT+TC vs. CC: OR=1.26, 95%CI: 1.021.55, Z=2.19, P=0.028; TT vs. TC+CC: OR=1.39, 95%CI: 1.041.87, Z=2.23, P=0.026). We also found significant association between them in subgroup of populationbased controls in the homozygous model (TT vs. CC: OR=1.27, 95%CI: 1.021.57, Z=2.16, P=0.031). ConclusionXPC rs2228000(C/T) polymorphism may be associated with the susceptibility of breast cancer, especially in Asian, and genetype TT may increase the risk of breast cancer.
