A nested lung cancer case-control study was carried out using 397 12 h urine samples originally collected from a cohort of over 26 000 women aged 40-64 at entry who were then followed for up to 15 years.
The urine samples from active smokers were first identified using a simple qualitative method and their total nicotine metabolites/creatinine ratios then determined by automated colorimetric methods.
The results obtained demonstrated the capacity of nicotine metabolite estimations in a single 12h sample of urine to predict the subsequent risk of lung cancer.
The risk of lung cancer among the biochemically proven active smokers during this period was 7.8 times that of the non-smokers, suggesting that the dose-response relationship between smoking and lung cancer is no less steep in women than in men.
The smoking-related risk of adenocarcinoma was less than that of other lung carcinomas.
It is suggested that this biochemical epidemiology approach to exploring the relationship between smoking and lung cancer could profitably be applied to the study of other smoking-related diseases.
