Further, Jang et al. did not observe an association between the VEGF-A -2578C>A polymorphism and the development of colorectal cancer [47], and Wang et al. reported that the -1498T>C polymorphism was not associated with urinary tract urothelial carcinoma or bladder cancer in a Taiwanese population [48]. Here, VEGFA is linked to urinary bladder carcinoma.
