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、SpringerVerlag、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, SpringerVerlag, China National Knowledge Infrastructure, Chinese Biomedical Literature Data, VIP Database and Wanfang Database, all eligible casecontrol 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 casecontrol studies were included, including 2 336 cases with gastric cancer and 3 502 controls. The Metaanalysis 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
