Abstract
AIM: To assess the relationship between XPD single nucleotide polymorphism (SNP) and susceptibility to gastric cancer in Han Chinese from northeast region via a hospital-based, case-control study.
METHODS: Polymerase chain reaction-restriction fragment length polymorphism analysis was used to determine the Asp312Asn and Lys751Gln polymorphisms of XPD gene in 238 patients with gastric cancer and 200 healthy controls. The adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariate logistic regression.
RESULTS: The polymorphism of Lys751Gln was not significantly different between gastric cancer patients and normal controls. The frequency of Asp/Asn and Asn/Asn genotypes in gastric cancer was significantly increased as compared with that in the controls (P = 0.041). Individuals carrying at least one 312Asn variant allele (Asp/Asn and Asn/Asn genotypes) tended to have an increased risk (1.901 times) for gastric cancer as compared with those with the Asp/Asp genotype (OR = 1.901, 95%CI: 1.119-3.229).
CONCLUSION: The Asp312Asn polymorphisms in XPD gene are risky factors of gastric cancer in Han Chinese from northeast region.
