摘  要:目的 探讨着色性干皮病C(XPC)基因939氨基酸位点Lys/Gln多态性与胃癌易感性的关系。方法 计算机检索PubMed、Cochrane Library、Elsevier、SpringerVerlag、中国期刊全文数据库(CNKI)、中国生物医学文献数据库(CBM)、维普中文科技期刊数据库(VIP)及万方医药期刊全文数据库,检索时间为建库至2015年9月,收集有关XPC Lys939Gln(A/C)基因多态性与胃癌易感性的病例对照研究。由两名评价员按照纳入、排除标准独立筛选文献,进行质量评价。采用STATA 12.0软件进行Meta分析,计算比值比(OR)及95%可信区间(CI)进行关联强度评价,并进行亚组、敏感性分析和发表偏倚的检测。结果 本研究共纳入7个病例对照研究,包括2 336例胃癌患者和3 502例健康对照。Meta分析结果显示,与等位基因A比较,等位基因C可增加胃癌的风险(OR=1.09,95%CI为1.01-1.18,Z=2.12,P=0.034);与基因型AA相比,纯合子模型(CC)和显性模型(CC+AC)基因型可增加罹患胃癌风险(CC vs.AA:OR=1.19,95%CI为1.00-1.42,Z=2.00, P=0.046;CC+AC vs.AA:OR=1.12,95%CI为1.00-1.25,Z=2.03,P=0.042)。对研究人群和对照来源进行亚组分析结果显示,在亚洲人群和社区来源的对照中,XPC Lys939Gln(A/C)基因多态性与胃癌风险有关。亚洲人群中,C vs.A: OR=1.10,95%CI为1.01-1.20,Z=2.28,P=0.023;CC vs.AA:OR=1.21,95%CI为1.01-1.46,Z=2.02,P=0.043;CC+AC vs.AA:OR=1.13,95%CI为1.01-1.27,Z=2.11,P=0.035。社区来源的对照组中,C vs.A:OR=1.11,95%CI为1.01-1.21,Z=2.25,P=0.024;CC vs.AA:OR=1.23,95%CI为1.02-1.50,Z=2.12,P=0.034。结论 XPC Lys939Gln(A/C)基因多态性可能与罹患胃癌的易感性有关。等位基因C、基因型CC和CC+AC可能增加胃癌的风险。Objective To explore the association between Xeroderma pigmentosum complementation C group (XPC) Lys939Gln (A/C) gene polymorphism and the susceptibility of gastric cancer. Methods By searching PubMed, Cochrane Library, Elsevier, SpringerVerlag, China National Knowledge Infrastructure, Chinese Biomedical Literature Data, VIP Database and Wanfang Database, all eligible casecontrol studies published up to September 2015 were selected and the quality of each article was valuated by two reviewers independently according to the inclusion and exclusion criteria. Meta-analysis was performed by using STATA 12.0 software. Odds ratio (OR) and 95% confidence interval (CI) were calculated. The text was estimated for the subgroup analysis, sensitivity analysis and publication bias test. Results A total of 7 casecontrol studies were included, including 2 336 cases with gastric cancer and 3 502 controls. The Metaanalysis showed that compared with the allele A, the allele C increased the risk of gastric cancer (OR=1.09, 95%CI: 1.01-1.18, Z=2.12, P=0.034); compared to the genotype AA, the homozygous model (CC) and dominant model (CC+AC) also increased the risk of gastric cancer (CC vs.AA: OR=1.19, 95%CI: 1.00-1.42, Z=2.00, P=0.046; CC+AC vs.AA: OR=1.12, 95%CI: 1.00-1.25, Z=2.03, P=0.042). The Meta-analysis showed the statistical significance between XPC Lys939Gln (A/C) gene polymorphism and the gastric cancer risk in subgroup of Asian people (C vs.A: OR=1.10, 95%CI: 1.01-1.20, Z=2.28, P=0.023; CC vs.AA: OR=1.21, 95%CI: 1.01-1.46, Z=2.02, P=0.043; CC+AC vs.AA: OR=1.13, 95%CI: 1.01-1.27, Z=2.11, P=0.035) and the source of community in the control group (C vs.A: OR=1.11, 95%CI: 1.01-1.21, Z=2.25, P=0.024; CC vs.AA: OR=1.23, 95%CI: 1.02-1.50, Z=2.12, P=0.034). Conclusion XPC Lys939Gln(A/C) gene polymorphism may be associated with the susceptibility of gastric cancer, and genotype CC, CC+AC and allele C can increase the risk of gastr
