Description of intervention(s) / exposure
This study will evaluate the efficacy of the existing smoking cessation program at Townsville Cancer Centre, its impact on smoking behaviour and the effect of smoking cessation on patient outcomes. The smoking cessation strategy includes assessment of smoking status, carbon monoxide breath testing, advice and counselling, pharmacotherapy with Nicotine patches, and referral to GP and/or Quitline. This strategy occurs at diagnosis and continues with ongoing counselling and pharmacotherapy during follow up visits.
The results of this study will help inform patients and health care providers and facilitate improvement in quality of care and patient compliance leading to improved disease control, survival and quality of life.
Patients will be followed up for 5 years from start of treatment.

Statistical methods / analysis
Main study:
Hypothesizing that 70% of the participants will stop smoking, our aim is to collect data from minimum 78 participants (current smokers) to determine the smoking cessation percentage with power of 0.90 and type 1 error of 0.05 (Two-tailed t test). We will also collect data from an equal non-smoking group (78) to achieve other objectives of the study. The sample size was calculated using Open Epi, version 3 factoring a 10% drop out rate.

Based on our experience, we have around 110 diagnosed annually with head and neck cancers of which 35% of them are smokers. To collect data from 78 of smokers over three years will be achievable.

Sub Study:
20 participants i.e. 10 from each group (current smokers and who have quit smoking)

Interim Analyses
The first interim analysis will occur at 15 months. This will contain the patient accrual rate, distribution of important baseline prognostic variables, smoking cessation rates, disease response rates, and frequency of toxicities. Statistical analysis will involve, as appropriate, paired-samples T-Tests, McNemar tests and paired Wilcoxon tests (for two group analysis), and repeated measures ANOVAs and Friedman tests (for analysis involving the 3 curative groups of surgery versus radiotherapy versus radiotherapy & surgery). Survival analysis will also be undertaken in the main 5-year follow-up study.
