Summary

The study investigates effectiveness of different smoking cessation methods and low-dose CT based lung cancer screening

Detailed description

The study population consists of individuals aged 50-74 years with a significant smoking history who continue to smoke. The study design is a prospective and participants are randomized into three study arms: low-dose CT (LDCT) + smoking cessation with a smartphone application (arm 1), LDCT + smoking cessation with written materials (arm 2), smoking cessation with a smartphone application without LDCT (arm 3). The study compares effectiveness of smoking cessation methods, LDCT in lung cancer screening, lung cancer stage distribution, and lung cancer specific survival.
