摘要:

目的 本研究对白细胞介素-8-251 T/A(interleukin-8-251 T/A,IL-8-251 T/A)(rs4073)与肺癌发生风险相关性文献进行Meta分析来评价两者相关性特征。方法 检索2013年12月1日之前PubMed中白细胞介素-8-251 T/A(interleukin-8-251 T/A,IL-8-251T/A)(rs4073)基因多态性与肺癌发生风险相关性病例对照研究的文献。应用Stata11.0软件合并计算A/A纯合子和携带A等位基因(T/A+A/A)杂合子与野生型T/T纯合子肺癌发生的比值比(odds ratios,OR)及95%置信区间(confidence intervals,CI),并按照亚裔与非亚裔人群进行亚组分析,评价IL-8-251T/A(rs4073)不同基因亚型与肺癌发生的相关性及与不同种族肺癌发生的相关性。结果 共有6篇文献符合纳入标准。合并计算所有纳入文献中的IL-8-251T/A(rs4073)A/A纯合子和携带A等位基因(T/A+A/A)杂合子与野生型T/T纯合子肺癌发生的OR值,肺癌组3 265例OR=1.03(95% CI=0.92~1.14,异质性P=0.235),对照组3 607例OR=1.07(95% CI=0.96~1.19,异质性P=0.245),IL-8-251T/A(rs4073)基因多态性与肺癌发生无相关性。当按亚裔与非亚裔人群进行亚组分析后,发现亚裔人群中携带A等位基因(T/A+A/A)杂合子(OR=1.48,95% CI=1.04~2.11,异质性P=0.030)和A/A纯合子(OR=1.35,95% CI=1.02~1.92,异质性P=0.090)与T/T纯合子肺癌发生风险有着显著的相关性。结论 IL-8-251T/A(rs4073)基因多态性在全部人群中与肺癌发生风险无相关性,但是在亚裔人群中A等位基因的存在与肺癌发生显著相关。

Abstract:

Objective To perform a meta-analysis to evaluate the association between the interleukin-8-251T/A(rs4073) gene polymorphism and lung cancer risk. Methods A literature search at PubMed was performed to identify case-control study articles published before December 1st, 2013. The Stata11.0 software was used to calculate the pooled odds ratios(OR) with 95% confidence intervals(CI). And the analysis was stratified by Asian and non-Asian populations. Results Totally six articles met our inclusion criteria. The included studies yielded a total of 3 265 lung cancer cases and 3607 controls. For the homozygous A/A and A allele carriers(T/A + A/A), the pooled ORs for all studies combining 3 265 cases and 3 607 controls were 1.03(95% CI=0.92-1.14, P=0.235 for heterogeneity) and 1.07(95% CI=0.96-1.19, P=0.245 for heterogeneity) when compared with the homozygous wild-type genotype(T/T). When the analysis was stratified by Asian and non-Asian populations, significant risks were found among Asians for both the A allele carriers(OR=1.48, 95% CI=1.04-2.11, P=0.030 for heterogeneity) and the homozygous A/A(OR=1.35, 95% CI=1.02-1.92, P=0.090 for heterogeneity) individuals. However, no significant associations were found in non-Asian populations using any of the genetic models. Conclusion This Meta-analysis suggests that the interleukin-8-251 allele confer an increased risk for the development of lung cancer among Asians.
