VEGFA and lung cancer: There was a marked association between VEGF -2578C > A A allele / CC genotype and lung cancer risk in overall and Asian populations (overall populations: A allele: OR = 1.26, 95% CI: 1.08–1.46, P = 0.003; CC genotype: OR = 0.72, 95% CI: 0.54–0.95, P = 0.02; Asians: A allele: OR = 1.33, 95% CI: 1.15–1.55, P = 0.0002; CC genotype: OR = 0.68, 95% CI: 0.50–0.93, P = 0.01).
