[The association of XPD G312A polymorphism with lung cancer risk: a meta-analysis].

ABSTRACT: It has been proven that close relation was existed between XPD polymorphism G312A and lung cancer risk. However, some of the results are not consistent. The aim of this study is to explore the impact of DNA repair gene XPD polymorphism G312A on lung cancer risk.The literatures eligible from PUBMED, EMBASE, CNKI and WANGFANG database were enrolled in the meta-analysis. Heterogeneity among combined studies was assessed. The pooled OR and 95%CI were calculated. The sensitivity analysis and the publication bias were evaluated by RevMan 5.0 and STATA 11.0.There were 6554 cases and 8322 controls from 18 studies included in the meta-analysis. In total, individuals with 312A allele and 312AA genotype showed increased lung cancer risk (A vs. G: OR = 1.06, 95% CI: 1.00-1.12; AA vs. AG+GG: OR = 1.20, 95% CI: 1.06-1.36; AA vs. GG: OR = 1.19, 95% CI: 1.04-1.36). In Asians, individuals with 312AA genotype showed 6.15 fold and 6.20 fold increased lung cancer risk in recessive genetic model and homogenous contrast respectively (AA vs. AG+GG: OR = 7.15, 95% CI: 1.90-26.94; AA vs. GG: OR = 7.20, 95% CI: 1.91-27.15). In Caucasians, individuals with 312AA genotype showed a 15% increased lung cancer risk (OR = 1.15, 95% CI: 1.01-1.31).XPD 312A allele is risk allele for lung cancer. Individuals with AA genotype have higher risk of lung cancer, especially in Asians.

Project description:The rs2736100 (A > C) polymorphism of the second intron of Telomerase reverse transcriptase (TERT) has been confirmed to be closely associated with the risk of Lung cancer (LC), but there is still no unified conclusion on the results of its association with LC. This study included Genome-wide association studies (GWAS) and case-control studies reported so far on this association between TERT rs2736100 polymorphism and LC to clarify such a correlation with LC and the differences in it between different ethnicities and different types of LC. Relevant literatures published before May 7, 2022 on 'TERT rs2736100 polymorphism and LC susceptibility' in PubMed, EMbase, CENTRAL, MEDLINE databases were searched through the Internet, and data were extracted. Statistical analysis of data was performed in Revman5.3 software, including drawing forest diagrams, drawing funnel diagrams and so on. Sensitivity and publication bias analysis were performed in Stata 12.0 software. The C allele of TERT rs2736100 was associated with the risk of LC (Overall population: [OR] = 1.21, 95%CI [1.17, 1.25]; Caucasians: [OR] = 1.11, 95%CI [1.06, 1.17]; Asians: [OR] = 1.26, 95%CI [1.21, 1.30]), and Asians had a higher risk of LC than Caucasians (C vs. A: Caucasians: [OR] = 1.11 /Asians: [OR]) = 1.26). The other gene models also showed similar results. The results of stratified analysis of LC patients showed that the C allele was associated with the risk of Non-small-cell lung carcinoma (NSCLC) and Lung adenocarcinoma (LUAD), and the risk of NSCLC and LUAD in Asians was higher than that in Caucasians. The C allele was associated with the risk of Lung squamous cell carcinoma (LUSC) and Small cell lung carcinoma(SCLC) in Asians but not in Caucasians. NSCLC patients ([OR] = 1.27) had a stronger correlation than SCLC patients ([OR] = 1.03), and LUAD patients ([OR] = 1.32) had a stronger correlation than LUSC patients ([OR] = 1.09).In addition, the C allele of TERT rs2736100 was associated with the risk of LC, NSCLC and LUAD in both smoking groups and non-smoking groups, and the risk of LC in non-smokers of different ethnic groups was higher than that in smokers. In the Asians, non-smoking women were more at risk of developing LUAD. The C allele of TERT rs2736100 is a risk factor for LC, NSCLC, and LUAD in different ethnic groups, and the Asian population is at a more common risk. The C allele is a risk factor for LUSC and SCLC in Asians but not in Caucasians. And smoking is not the most critical factor that causes variation in TERT rs2736100 to increase the risk of most LC (NSCLC, LUAD). Therefore, LC is a multi-etiological disease caused by a combination of genetic, environmental and lifestyle factors.
