In women who did not smoke, positive associations were observed for styrene/ethylbenzene and dimethylformamide/methylisocyanate biomarkers. [CONCLUSION] Exposure to PAHs, TSNAs and several VOCs through tobacco smoking were associated with increased lung cancer risk among women.

Abstract 한글 요약
[BACKGROUND] The constituents of tobacco smoke that specifically contribute to lung cancer risk have yet to be fully identified. We evaluated associations between biomarkers of potentially harmful constituents-polycyclic aromatic hydrocarbons (PAHs), tobacco-specific nitrosamines (TSNAs), nicotine, and volatile organic compounds (VOCs)-and lung cancer incidence among US women.
[METHODS] In a case-cohort study nested within the Sister Study (women aged 35 to 74 years at baseline, enrolled 2003 to 2009), data were obtained for a random subcohort and all remaining incident lung cancers through September 2017 (median follow-up 9.6 years), stratified by race and ethnicity (Hispanic, non-Hispanic Black, non-Hispanic White, others) and smoking status (current, former, never). The analytic sample included 356 cases and 433 non-cases. We quantified 30 biomarkers in baseline urine samples and calculated hazard ratios (HRs) for associations between one-unit increase in biomarker concentrations (log-scale) and lung cancer incidence using weighted Cox regression models adjusted for urinary creatinine and demographic, health, and lifestyle factors.
[RESULTS] Among women who were currently smoking at enrolment, positive associations were observed for biomarkers of PAHs (naphthalene, phenanthrene, pyrene, fluorene; HRs 1.4 to 5.3), TSNAs (particularly 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK); HRs : 1.3-2.2), and VOCs (xylene, acrylamide, acrylonitrile, 1,2-dibromoethane/vinyl-chloride/ethylene-oxide/acrylonitrile, acrolein, styrene/ethylbenzene, benzene, dimethylformamide/methylisocyanate, 1,3-butadiene, crotonaldehyde, isoprene; HRs : 1.6-4.4). Associations with biomarkers of most PAHs, NNK, xylene, and dimethylformamide/methylisocyanate remained after additional adjustment for smoking frequency, duration, and nicotine metabolites. In women who did not smoke, positive associations were observed for styrene/ethylbenzene and dimethylformamide/methylisocyanate biomarkers.
[CONCLUSION] Exposure to PAHs, TSNAs and several VOCs through tobacco smoking were associated with increased lung cancer risk among women.
