Specifically, we evaluated the association between clinical outcomes in gastric cancer, including overall survival, and each of the following SNPs: three TGFB1 SNPs, including one promoter SNP (-509 C>T) and two exon 1 SNPs (+869 T>C and +915 G>C) and three VEGF SNPs, including one promoter SNP (-1498T>C), one 5'-untranslated region SNP (-634G>C) and one 3'-untranslated region SNP (+936 C>T). Here, VEGFA is linked to gastric cancer.
