[Smoking cessation and lung cancer screening]

Area of Science:

• Pulmonology
• Oncology
• Public Health

Background:

• Lung cancer screening using annual low-dose computed tomography (CT) scans is proven to reduce mortality rates in high-risk populations, including smokers and ex-smokers.
• Despite evidence, this screening strategy is not yet established in France by the French High Authority for Health.
• Smoking cessation is the most critical factor in reducing lung cancer mortality.

Purpose of the Study:

• To highlight the importance of combining smoking cessation interventions with lung cancer screening.
• To identify the need for further research into optimal smoking cessation strategies within lung cancer screening programs.

Main Methods:

• Review of existing studies on lung cancer screening and smoking cessation.
• Identification of limitations in current data regarding smoking cessation interventions for screened populations.

Main Results:

• Lung cancer screening, particularly low-dose CT, significantly reduces mortality in targeted individuals.
• An integrated approach of screening and smoking cessation is crucial for maximizing mortality reduction.
• Limited randomized studies exist to guide clinicians on the best smoking cessation methods for this population.

Conclusions:

• The combination of lung cancer screening and smoking cessation interventions holds the greatest potential for reducing lung cancer mortality.
• Further research is essential to determine optimal smoking cessation strategies, timing, and therapies within lung cancer screening contexts.
• Clarifying these approaches is necessary for effective implementation and improved patient outcomes.
