Importance of Smoking Cessation in a Lung Cancer Screening Program

Early detection of lung cancer and smoking cessation interventions can decrease lung cancer mortality, but information on the effectiveness and interaction between smoking cessation and lung cancer screening is sparse and inconsistent. This review aims to synthesize recent studies in two major areas of interest. First, we explore the interactions and potential for synergies between lung cancer screening programs and smoking cessation by summarizing reported changes in smoking behavior observed in major screening trials in the US and Europe, as well as attempts to use smoking cessation interventions to augment the benefits from lung cancer screening programs. Second, we review the interaction between smoking habits and pre-/post-operative pulmonary resection outcomes, including changes in smoking behavior post-diagnosis and post-treatment. Information from these areas should allow us to maximize benefits from smoking cessation interventions through the entire lung cancer screening process, from the screen itself through potential curative resection after diagnosis.
