Smoking during cancer treatment is associated with reduced treatment response and cancer recurrence in patients with tobacco-related cancers. The purpose of this study was to examine smoking characteristics in head and neck cancer patients ( = 503) with a history of smoking and examine the impact of an intensive clinical tobacco intervention to patients who were currently smoking. All participants completed an interviewer-administered questionnaire at study enrollment which examined smoking behaviours, motivations to quit, and strategies used to cessate smoking. Follow-up assessments were completed at 6- and 12-months which monitored whether patients had quit smoking, remained cessated, or continued to smoke since study recruitment. For those who were currently smoking ( = 186, 37.0%), an intensive clinical tobacco intervention that utilized the 3A's-Ask, Advise, Arrange-and the Opt-Out approach was offered to assist with smoking cessation at their new patient visit and followed-up weekly during their head and neck radiation therapy for 7 weeks. At 6 months, 23.7% ( = 41) of those who were smoking successfully quit; 51.2% quit 'cold turkey' (defined as using no smoking cessation assistance, aids or pharmacotherapy to quit), while 34.9% used pharmacotherapy (varenicline (Champix)) to quit. On average, it took those who were smoking 1-5 attempts to quit, but once they quit they remained cessated for the duration of the study. Although the head and neck cancer patients in this study reported high levels of nicotine dependence, many were able to successfully cessate.
