Several studies evaluated the association between myeloperoxidase (MPO) -463 G/A polymorphism and the risk of lung cancer. However, the results were not stable.
Online electronic databases (PubMed, EMBASE, and Wanfang database) were searched. The strength of association between the MPO -463 G/A polymorphism and lung cancer risk was assessed by calculating odds ratios (OR) with 95% confidence interval (CI).
A total of 22 studies with 7420 cases and 9132 controls on the association between MPO -463 G/A polymorphism and lung cancer risk were included for this meta-analysis. MPO -463 G/A polymorphism was associated with a significantly decreased risk of lung cancer (OR = 0.91; 95% CI: 0.85-0.98; I = 25%). In the race subgroup analysis, Asians with MPO -463 G/A polymorphism had decreased lung cancer risk (OR = 0.81; 95% CI: 0.70-0.93; I = 0%). However, Caucasians did not show significant result (OR = 0.93; 95% CI: 0.86-1.02; I = 36%). In the subgroup analysis according to source of control, both population-based studies and hospital-based studies were marginally significantly associated with decreased risk of lung cancer (OR = 0.90; 95% CI: 0.82-1.00; I = 41% and OR = 0.91; 95% CI: 0.82-1.01; I = 0%).
The present meta-analysis suggested that the MPO -463 G/A polymorphism carriers had a protective role in lung cancer.
多项研究评估了髓过氧化物酶（MPO）-463 G/A多态性与肺癌风险之间的关联。然而，结果并不稳定。
检索在线电子数据库（PubMed、EMBASE和万方数据库）。通过计算比值比（OR）及95%置信区间（CI）评估MPO -463 G/A多态性与肺癌风险之间的关联强度。
本荟萃分析纳入了22项研究，共7420例病例和9132例对照，研究MPO -463 G/A多态性与肺癌风险之间的关联。MPO -463 G/A多态性与肺癌风险显著降低相关（OR = 0.91；95% CI：0.85 - 0.98；I² = 25%）。在种族亚组分析中，具有MPO -463 G/A多态性的亚洲人肺癌风险降低（OR = 0.81；95% CI：0.70 - 0.93；I² = 0%）。然而，高加索人未显示出显著结果（OR = 0.93；95% CI：0.86 - 1.02；I² = 36%）。在根据对照来源进行的亚组分析中，基于人群的研究和基于医院的研究均与肺癌风险降低存在边缘显著关联（OR = 0.90；95% CI：0.82 - 1.00；I² = 41%和OR = 0.91；95% CI：0.82 - 1.01；I² = 0%）。
本荟萃分析表明，MPO -463 G/A多态性携带者对肺癌具有保护作用。
