To investigate the association among XRCC1 polymorphisms, smoking, drinking and the risk of prostate cancer (PCa) in men from Han, Southern China.


In a case-control study of 207 patients with PCa and 235 cancer-free controls, frequency-matched by age, we genotyped three XRCC1 polymorphisms (codons 194, 280 and 399) using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RELP) method.


Among the three polymorphisms, we found that the XRCC1 Arg399Gln variant allele was associated with increased PCa risk (adjusted odd ratio [OR]: 1.67, 95% confident interval [CI]: 1.11-2.51), but the XRCC1 Arg194Trp variant allele had a 38% reduction in risk of PCa (adjusted OR: 0.62, 95% CI: 0.41-0.93). However, there was no significant risk of PCa associated with Arg280His polymorphism. When we evaluated the three polymorphisms together, we found that the individuals with 194Arg/Arg wild-type genotype, Arg280His and Arg399Gln variant genotypes had a significantly higher risk of PCa (adjusted OR: 4.31; 95% CI: 1.24-14.99) than those with three wild-type genotypes. In addition, we found that Arg399Gln variant genotypes had a significant risk of PCa among heavy smokers (adjusted OR: 2.04; 95% CI: 1.03-4.05).


These results suggest that polymorphisms of XRCC1 appear to influence the risk of PCa and may modify risks attributable to environmental exposure.
