Objective To investigate the correlation of X-ray repair cross-complementing gene 1 (XRCC1-Arg399Gln, Arg280His, and Arg194Trp) polymorphisms and susceptibility to gastric cancer. Methods One hundred and twenty patients with gastric cancer were included in study group, 120 healthy volunteers were included in control group. The DNA was extracted from peripheral blood. Arg399Gln, Arg280His, and Arg194Trp gene polymorphisms were detected and analyzed using polymerase chain reaction-restriction fragment length polymorphism technique, and the susceptibility between different genotypes and gastric cancer was compared in two groups. Results The age, gender, smoking, drinking, diet, and other common characteristics of exposure factors had no significant differences in two groups (P > 0.05). The mutation locus genotype frequencies of Arg399Gln and Arg280His had no significant differences between two groups (P > 0.05). However, the mutation locus genotype frequencies of Arg/Trp, Trp/Trp, and Arg/Trp+Trp/Trp were higher and the mutation locus genotype frequency of Arg/Arg was lower in the study group as compared with the control group (P < 0.05). Conclusion The preliminary results from this study shows that XRCC1 Arg399Gln and Arg280His polymorphisms are not correlated with susceptibility to gastric cancer; However, Arg194Trp polymorphism is correlated with susceptibility to gastric cancer.
