- head and neck cancer;
A behavioral phenotype that characterizes nicotine dependence, the time to first cigarette after waking, is hypothesized to increase the risk of head and neck cancer.
A case-control study of histologically confirmed head and neck cancer was conducted that included 1055 cases and 795 controls with a history of cigarette smoking.
The pack-years–adjusted odds ratio was 1.42 (95% confidence interval [95% CI], 1.02-1.99) for an interval of 31 minutes to 60 minutes to first cigarette after waking and 1.59 (95% CI, 1.19-2.11) for an interval of 1 minute to 30 minutes. The risk estimates were similar when smoking was modeled as total years, smoking status (current vs former), number of cigarettes smoked per day, years since quitting, and excess odds ratio. Findings were consistent for cancers of the floor of the mouth, palate, and pharynx.
Time to first cigarette is an indicator of increased nicotine dependence, smoke uptake, and risk of head and neck cancer. This high-risk group of individuals would benefit from targeted smoking interventions. Cancer 2011;. © 2011 American Cancer Society.
