Genetic polymorphisms in drug-metabolizing, DNA repair and multidrug resistance genes affect the risks for many cancers. We analyzed 21 polymorphisms in 17 genes in these pathways to evaluate their association with the risk of acute myeloid leukemia (AML) and to examine whether smoking modifies these associations in a population-based study in Korea (415 cases, 1700 controls). We found marginal associations between the risk of AML and CYP1A1 1188, and XRCC1 194, ERCC1 IVS5 + 33 and WRN 787 polymorphisms. However, when we performed the analysis according to smoking exposure, we found a stronger association for ERCC1 only in the non-smoking population (odds ratio [OR] = 0.74; 95% confidence interval [CI] = 0.60-0.91, p = 0.004), while we found the GSTT1-null genotype to be associated with an increased risk of AML in ever-smokers (OR = 1.51; 95% CI = 1.06-2.15, p = 0.02). These results indicate that ERCC1 and GSTT1-null polymorphisms may have an effect on AML risk that is dependent on smoking exposure.
