The aim of the study is to study the correlation of genetic polymorphism of vascular endothelial growth factor (VEGF) gene with susceptibility to primary lung cancer. A total of 414 patients with primary lung cancer and 338 healthy volunteers were enrolled in this case-control study from September 2008 to October 2011. Gene identification with PCR-RFLP (polymerase chain reaction-based restriction fragment length polymorphism) was used to detect in white blood cells from the subjects the single-nucleotide polymorphisms (SNP) of VEGF gene, including +405G/C, -460 T/C, -1154G/A, -2578C/A sites. Association of genotypes or haplotypes with susceptibility of lung cancer was analyzed with unconditional logistic regression adjusted by gender and age. Smoking was significantly associated with increased risk of lung cancer. Gene phenotypic analysis demonstrated that C allele of +405G/C in VEGF gene was significantly associated increased risk of lung cancer in males (P = 0.0094, odds ratio = 1.634.3), as that with carrying GCTC haplotype (odds ratio = 1.349), whereas carrying GACG had decreased risk for lung cancer (odds ratio = 0.044). No relationship existed between 460 T/C, -1154G/A, -2578C/A alleles of VEGF gene and risk of lung cancer. VEGF gene polymorphism may have a role in the development of lung cancer.
