The aim of this meta-analysis is to generate large-scale evidence on whether common vascular endothelial growth factor (VEGF) gene polymorphisms (-2578C/A [dbSNP: rs699947] and -460C/T [dbSNP: rs833061]) are associated with lung cancer. A literature search of PubMed, Embase, Web of Science, Cochrane Library, and CBM databases was conducted to identify all eligible studies published before May 3, 2013. Crude odds ratios (ORs) with their corresponding confidence intervals (95% CIs) were used to evaluate the strength of the association. Eleven case-control studies were included with a total of 3,861 lung cancer cases and 3,676 controls in this meta-analysis. For the VEGF -2578C/A polymorphism, the combined results showed that there exist highly significant risk factors for individuals carrying the A allele resulting in lung cancer, and the magnitude of this effect was similar in smoker patients and squamous cell carcinoma (SCC) patients. Unlike the situation with the -2578C/A polymorphism, the VEGF -460C/T polymorphism is not associated with the risk of lung cancer in neither Asians nor Caucasians. However, when stratified according to smoking status and histological types of lung cancer, we found that the T allele (-460C/T) was associated with decreased lung cancer risk among nonsmoker patients and SCC patients. Our findings showed that the -2578C/A polymorphism may increase lung cancer risk, especially in smoker patients and SCC patients, whereas the -460C/T polymorphism may decrease lung cancer risk, especially in nonsmoker patients and SCC patients.
