[Smoking cessation and lung cancer screening]

Abstract

Several studies have shown that lung cancer screening, using annual low-dose computed tomography (CT) scan in a targeted population of smokers and ex-smokers reduces overall and lung cancer specific mortality rates. This form of screening strategy is not currently established for use in France by the French High Authority for Health. Quitting smoking is the most important measure in reducing mortality from lung cancer. The maximum benefit in reducing mortality from lung cancer should be seen through an effective combination of smoking cessation intervention and chest CT screening to identify early, curable disease. However, current data to guide clinicians in the choice of smoking cessation interventions in this specific context are limited due to the small number of randomized studies that have been carried out. The optimal approach to smoking cessation during lung cancer screening needs to be clarified by new studies comparing different motivation strategies, establishing the ideal moment to propose stopping smoking and the most effective therapies to use.
