A large project consisting of:
a) an observational trial where smoking status is recorded on 1400 consecutive people newly diagnosed with lung cancer. Smoking status is biologically validated with exhaled carbon monoxide (eCO) levels every 3 months. Survival, cancer progression and treatment complications will be recorded and compared in smokers, ex-smokers and never smokers.
|Condition or disease|
Smoking causes around 85% of lung cancer. Continued smoking after diagnosis probably worsens survival and increases treatment complications but prospective well-designed studies are lacking.
This project is an observational cohort study recording outcomes in smokers, never-smokers, and ex-smokers, using exhaled carbon monoxide to validate smoking status when they attend for further lung cancer clinics.
This project is unique, as every patient with a clinical diagnosis of lung cancer will have their smoking status biologically validated by a quick and easy test, and those enrolled in the smoking cessation treatments or not will also complete a generic quality of life questionnaire at regular intervals. These appointments will coincide with other hospital appointments wherever possible, and survival status will reported up to 24 months after enrolment.

- Median and 2-year survival rates in confirmed smokers versus non- smokers newly diagnosed with lung cancer. [ Time Frame: 24 months ]
- Median survival and 2-year survival rates by smoking status for early (Stage I/II NSCLC) versus those with advanced (Stage III/IV) NSCLC. [ Time Frame: 24 months ]
- Number of treatment complications in smokers versus non-smokers (frequency surgical wound complications, radiotherapy induced pneumonitis and median total radiation (Gy) dose; frequency and duration of neutropenic sepses [ Time Frame: 2 years ]
- Point prevalence of smoking at 0, 3, 6 12, 24 months [ Time Frame: 2 years ]
- Comparison of changes in health related quality of life (EQ5D) in smokers versus non-smokers [ Time Frame: 2 years ]
- Accrual and attendance rates of lung cancer patients attending a hospital smoking cessation service [ Time Frame: 2 years ]
- Estimate of cost per quality adjusted life year gained by smoking cessation advice in both quit strategies for smokers [ Time Frame: 2 years ]
