[摘要] 目的 系統评价Runt相关转录因子3(RUNX3)(rs760805)基因多态性与胃癌发病风险的相关性。 方法 计算机检索数据库PubMed、EMbase、The Cochrane Library(2018年3期)、CMB、CNKI、VIP、Wanfang data,检索时间为建库到2018年3月,筛选关于RUNX3基因多态性与胃癌相关性的病例对照研究,语言限定为中文与英文。由两位评价员独立筛选文献,提取资料并评价纳入研究的偏倚风险,使用Newcastle-Ottawa量表(NOS)评价研究质量。对RUNX3(rs760805)各基因型模型进行比较,包括A与T、AA与TT、AA与TA+TT、TA与TT、AA+TA与TT,综合分析其在病例组和对照组中的分布情况。通过Q检验和I2值分析各研究间的异质性,应用Egger′s回归法验证评估发表偏倚,采用Stata 12.0软件进行Meta分析,计算比值比(OR)及95%置信区间(95%CI),评估RUNX3(rs760805)基因多态性与胃癌发病风险的相关性。 结果 本研究共纳入5项病例对照研究,共有1363例胃癌患者及1346例健康对照。Meta分析结果显示:RUNX3(rs760805)基因多态性与胃癌发病风险有关[A vs. T:OR = 1.27,95%CI(1.01, 1.59),P = 0.039;AA+TA vs. TT:OR = 1.30,95%CI(0.96,1.77),P = 0.091;AA vs. TT+TA:OR = 1.18,95%CI(0.99, 1.41),P = 0.073;AA vs. TT:OR = 1.51,95%CI(0.97,2.33),P = 0.065;TA vs. TT:OR = 0.73,95%CI(0.32,1.63),P = 0.437]。 结论 RUNX3(rs760805)基因多态性与胃癌发病风险之间具有相关性,且等位基因A可能是胃癌的潜在危险因素。

[Abstract] Objective To systematically evaluate the association between rs760805 polymorphism in Runt-related transcription factor 3 (RUNX3) gene and risk of gastric cancer. Methods PubMed, EMbase, The Cochrane Library (Issue 3, 2018), CMB, CNKI, VIP and Wanfang databases were searched, retrieval time form creating database to March 2018, the data of case-control studies on the correlation between polymorphisms of RUNX3 gene and risk of gastric cancer were retrieved, the language was limited to Chinese and English. Two evaluators independently screened literature, extracted data and evaluated the bias risk of included studies, and used Newcastle-Ottawa scale (NOS) to evaluate research quality. All genotype models of RUNX3 (rs760805) were compared, including A and T, AA and TT, AA and TA+TT, TA and TT, AA+TA and TT, and their distribution in case group and control group was comprehensively analyzed. Q-test and I2 value were used to analyze the heterogeneity among the studies, egger′s regression was used to verify the evaluation of publication bias, and Stata 12.0 software was used for Meta-analysis. The correlation of RUNX3 (rs760805) gene polymorphism with the risk of gastric cancer was calculated by using the odds ratio (OR) and 95% confidence interval (95%CI). Results A total of 5 case-control studies were included (gastric cancer cases: 1363, healthy controls: 1346). The results of Meta-analysis showed that (rs760805) polymorphism in RUNX3 gene was associated with risk of gastric cancer [A vs. T: OR = 1.27, 95%CI (1.01, 1.59), P = 0.039; AA+TA vs. TT: OR = 1.30, 95%CI (0.96, 1.77), P = 0.091; AA vs. TT+TA: OR = 1.18, 95%CI (0.99, 1.41), P = 0.073; AA vs. TT: OR = 1.51, 95%CI (0.97, 2.33), P = 0.065; TA vs. TT: OR = 0.73, 95%CI (0.32, 1.63), P = 0.437]. Conclusion There is a correlation between the genetic polymorphism of RUNX3 (rs760805) and the risk of gastric cancer, and allele A may be a potential risk factor for gastric cancer.

胃癌是全世界最常見癌症之一[1]。据统计,全球每年有989 000例新发病例,其发病率居癌症总体第四位,死亡率居第二位[2],严重威胁生命健康。我国胃癌发病和死亡人数分别占全球胃癌发病和死亡的40%以上[3],疾病负担十分严重。近年来,随着新型医疗模式的兴起,在分子学水平将个人基因、环境与生活习惯差异考虑在内,以胃癌患者基因组信息为基础的胃癌精准医疗越来越受到关注[4]。……
