The study involved 113 lung cancer patients and 121 noncancercontrols divided into never, light and heavy smokers according to pack-years of smoking in Japanese byusing PCR-RFLP. For light smokers, the lung cancer risk of NAT2 intermediate-slow was significantly increased[the adjusted odds ratio (OR): 10.9, 95% confidence intervals (95%CI): 1.75-67.5, P-value: 0.010]. Moreover,never smokers having joint genotypes of NAT2 intermediate-slow and CYP1A2*1F A/A was also associated withincreased the lung cancer risk (OR: 4.95, 95% CI: 1.19-20.6, P-value: 0.028). We suggested that light smokerswith intermediate-slow NAT2 activity were at highest risk for lung cancer and the gene-gene interaction based onintermediate-slow NAT2 activity and high CYP1A2 activity would be increased a lung cancer risk among neversmokers.}, keywords = {Genetic polymorphism,NAT2,CYP1A2,Lung cancer,smoking}, url = {https://journal.waocp.org/article_24569.html}, eprint = {https://journal.waocp.org/article_24569_1513c4e5017602e5b82f8da9d64e68fc.pdf} }
