Association between EGF, TGF-β1, VEGF gene polymorphism and colorectal cancer.

Introduction Up to the present, EGF 61 A/G, TGF-β1 −509 T/C, and VEGF 936 T/C gene polymorphisms have been analyzed in other cancer entities than colorectal cancer. We have now investigated the frequency of these gene polymorphisms among colorectal cancer patients.
