Primary outcomePrimary: Concentration of γ-OH-Acr-dGuo, a Major Acrolein-DNA Adduct — 49.7; 67.1; 46.5 10^9 nucleotides/mL
Summary
DNA adducts in the oral mucosa cells of 100 smokers from 3 ethnic groups - Native Hawaiians, Whites, and Japanese Americans with differing risks for lung cancer upon cigarette smoking will be quantified. DNA adducts of tobacco smoke carcinogens will be quantified using both targeted and untargeted approaches.
