摘要 目的采用meta分析评估rs2298881多态性与胃癌易感性的关系。方法利用PubMed、Medline、Embase、Cochrane、Ovid、Web of Science和中国知网、维普、万方(截至2020年3月)数据库进行全面检索。计算共显性基因模型(AA vs. CC和AC vs. CC)、显性基因模型(AA+AC vs. CC)、隐性基因模型(AA vs. AC+CC)和等位基因模型(A vs. C)的效应指标OR值及95%CI,使用STATA 11.1软件进行meta分析。结果本研究共纳入5篇文献,累计病例3207例,对照3797例。meta分析结果显示,在共显性、显性和等位基因模型中,rs2298881基因多态性与胃癌易感性无相关性(AA vs.CC:OR=0.813,95%CI:0.606~1.091,P=0.618;AC vs.CC:OR=1.056,95%CI:0.876~1.274,P=0.568;AA+AC vs.CC:OR=0.978,95%CI:0.818~1.170,P=0.810;A vs. C:OR=0.933,95%CI:0.792~1.099,P=0.405)。在隐性基因模型中,rs2298881多态性与胃癌易感性有关(AA vs. AC+CC:OR=0.817,95%CI:0.705~0.946,P=0.007)。结论除隐性基因模型外,rs2298881基因多态性与胃癌易感性之间不存在相关性,而在隐性模型中,rs2298881AA基因型可以降低胃癌易感性。
