Accuracy of self-reported tobacco assessments in a head and neck cancer treatment population

Radiother Oncol. 2012 Apr;103(1):45-8. doi: 10.1016/j.radonc.2011.11.003. Epub 2011 Nov 25.


Prospective analysis was performed of self-reported and biochemically confirmed tobacco use in 50 head and neck cancer patients during treatment. With 93.5% compliance to complete weekly self-report and biochemical confirmatory tests, 29.4% of smokers required biochemical assessment for identification. Accuracy increased by 14.9% with weekly vs. baseline self-reported assessments. Data confirm that head and neck cancer patients misrepresent true tobacco use during treatment.
