摘要: 目的定量探讨着色性干皮病C组(XPC)基因rs2228000(C/T)多态性与乳腺癌易感性之间的关系。方法通过计算机检索PubMed、Cochrane Library、中国生物医学文献数据库(CBM)、万方医药期刊全文数据库、中国期刊全文数据库(CNKI)及维普数据库(VIP),检索时间截至2015年12月,搜集有关XPC rs2228000(C/T)位点多态性与乳腺癌风险的病例对照研究。采用STATA 12.0软件进行结果分析,计算比值比(OR)和95%CI。结果总共纳入8篇文献,包括9个病例对照研究(3 850例乳腺癌患者和5 047例健康对照)。纯合子模型(TT vs. CC:OR=1.28,95%CI为1.08~1.52,Z=2.80,P=0.005)和隐性模型(TT vs. TC+CC:OR=1.23,95%CI为1.05~1.43,Z=2.64,P=0.008)中XPC rs2228000(C/T)多态性与乳腺癌易感性有关,而等位基因模型、杂合子模型、显性基因模型中XPC rs2228000(C/T)位点多态性与乳腺癌风险无关(P>0.05)。在亚洲人群和PCRRFLP亚组的4种基因模型中,XPC rs2228000(C/T)多态性与乳腺癌易感性有关(T vs. C:OR=1.21,95%CI为1.05~1.40,Z=2.63,P=0.009;TT vs. CC:OR=1.55,95%CI为1.13~2.13,Z=2.70,P=0.007;TT+TC vs. CC:OR=1.26,95%CI为1.02~1.55,Z=2.19,P=0.028;TT vs. TC+CC:OR=1.39,95%CI为1.04~1.87,Z=2.23,P=0.026)。基于对照组来源的亚组分析,社区来源的纯合子模型中XPC rs2228000(C/T)多态性与乳腺癌发病风险有关(TT vs. CC:OR=1.27,95%CI为1.02~1.57,Z=2.16,P=0.031)。结论XPC rs2228000(C/T)多态性可能与乳腺癌风险有关,尤其在亚洲人群中,基因型TT可能增加乳腺癌发病风险。

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.
