Genetic polymorphism in DNA repair genes may influence individual variation in DNA repair capacity, which may be associated with cancer risks. This hospital-based case-control study examined whether polymorphism in the DNA repair gene x-ray repair cross-complementing groups 1 (XRCC1 Arg194Trp [C-->T], Arg280His [G-->A], and Arg399Gln [G-->A]) played a role(More)
