摘  要:目的:本Meta分析旨在探讨基质金属蛋白酶-2(matrix metalloproteinase-2,MMP-2)基因启动子区单核苷酸(C-1306T,rs243865)多态性与胃癌(gastric cancer,GC)易感性的关联.方法:参照Cochrance协作网制定的检索策略进行检索,计算机检索MEDLINE(1966-2013)、the Cochrane Library Database(Issue 12,2013)、EMBASE(1980-2013)、CINAHL(1982-2013)、Web of Science(1945-2013)、中国生物医学文献数据库(CBM)(1982-2013)、万方(1998-2013)和中国知网(CNKI)(1915-2013)等.使用STATA12.0统计软件进行M e t a分析,分别计算危险比(risk ratio,RR)及其95%可信区间(95%confidence intervals,95%CI).结果:本Meta分析共计纳入7项病例对照研究,1687例GC患者和2253名健康对照者.Meta分析结果表明:MMP-2基因C-1306T多态性可能与GC发生风险显著相关等位基因模型:RR=1.05,95%CI:1.03-1.08,P<0.001;显性基因模型:RR=1.01,95%CI:1.00-1.02,P=0.046.根据种族不同进行亚组分析发现:在亚洲人群中,MMP-2基因C-1306T多态性可能增加患GC的风险RR=1.06,95%CI:1.04-1.08,P<0.001,但在欧美人群中见明显关联性(P>0.05).进一步根据检测方法、基因型、样本量大小进行亚组分析发现,在多数亚组中发现他们之间均存在显著相关性(均P<0.05).结论:MMP-2基因C-1306T多态性可能与亚洲人群GC易感性的增加有关.AIM: To explore the correlation between the matrix metalloproteinase-2 (MMP-2) gene promoter sin- gle nucleotide polymorphism C-1306T (rs243865) and susceptibility to gastric cancer (GC). METHODS: A computer search of MEDLINE (1966-2013), the Cochrance Library Database (Issue 12, 2013), EMBASE(1980-2013), CINAHL (1982-2013), Web of Science (1945-2013), Chi- nese Biomedical Literature Database (CBM) (1982-2013), Wanfang (1998-2013) and CNKI (1915-2013) was performed to retrieve relevant studies. Meta-analysis was performed using STA- TA12.0 statistical software. Risk ratio (RR) and 95% confidence interval (CI) were calculated. RESULTS: Seven independent case-controlstudies with a total of 1687 GC patients and 2253 healthy subjects met the inclusion criteria. The findings of the meta-analysis demonstrated that MMP-2 C-1306T polymorphism may be significantly associated with an increased risk of GC [allele model: RR = (1.05, 95%CI: 1.03-1.08), P 〈 0.001; dominant model: RR= (1.01, 95%CI: 1.00-1.02), P= 0.046]. Results of subgroup analy- sis by ethnicity showed a significant positive correlation between MMP-2 C-1306T polymor- phism and GC risk among Asians [RR =(1.06, 95%CI: 1.04-1.08), P 〈 0.001], but not among Caucasians (P 〉 0.05). Further subgroup analy- ses according to the detection method, genotype, and sample size found that there were signifi- cant correlations (P 〈 0.05 for all) between them in most subgroups. CONCLUSION: Our findings confirm the hy- pothesis that MMP-2 C-1306T polymorphism may contribute to an increased risk of GC, espe- cially among Asian populations.
