Studies Examining the Importance of Smoking After Being Diagnosed With Lung Cancer

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.
