Abstract： 目的 探讨白介素8-251位点(IL8-251)的基因多态性与胃癌易感性的关系.方法 以胃癌组和健康对照组基因型分布的OR值为效应指标,全面检索相关文献,纳入符合人选标准的文献,应用REVMAN 4.2软件对各研究结果进行异质性检验和效应值合并.共纳入文献8篇,纳入数据合并的8项研究累计病例2114例,对照2505例.结果 通过对各研究的(AA+AT)/TT结果的异质性检验得X2值为21.48(P=0.003),随机效应模型计算合并的OR值为1.12(95%CI 0.90～1.40),剔除权重较大的研究后进行的敏感性分析显示其余的各研究同质,固定效应模型的合并OR值为1.21(95%CI 1.06～1.39).结论 携带IL8-251 A等位基因的个体发生胃癌的风险增加.
