VEGFA and colorectal cancer: In a Greek gastric cancer study of five VEGF SNPs (-2578C>A, -1154G>A, -634G>C, -460T>C, and +936C>T) in 312 patients [36], VEGF -2578 AA, -634 CC and +936TT genotypes were associated with a significantly lower HR (better survival) for 6-year survival of colorectal cancers.
