To date, no study has investigated the association between CYP1A2-163C/A polymorphism and bladder cancer risk in a Chinese population. Here, we extracted genomic DNA from peripheral white blood cells, and differentiated CYP1A2 alleles by polymerase chain reaction-based restriction fragment length polymorphism methods. Differences in genotype frequencies between the cases and controls were evaluated using a chi-square test. The odds ratio (OR) and its 95% confidence interval (CI) were calculated using an unconditional logistic regression model. This revealed that the -163A allele was present at a significantly increased frequency in bladder cancer patients compared to healthy controls (44.10 vs 22.25%, P CYP1A2-163C/A polymorphism is associated with increased susceptibility to bladder cancer in the Chinese population.
