An interventional study of Smoking cessation mobile application and Written material for smoking cessation in Lung Cancer Screening, sponsored by Oulu University Hospital. Active, not recruiting at 2 sites in Finland. Open to participants aged 50 Years to 74 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-08-24.
Sponsored by Oulu University Hospital · Not applicable, Interventional, and Prevention
This is a randomized phase II trial investigating different smoking cessation methods in study subjects undergoing lung cancer screening with low-dose CT (LDCT). The study also evaluates feasibility and outcomes of LDCT screening and potential biomarkers and AI-based evaluation on CT-scans. The study subjects fulfilling I/E-criteria are randomized in 1:1 fashion to yearly LDCT for two rounds with standard smoking cessation (control) or same LDCT approach combined to mobile application based smoking cessation (intervention).
Oulu University Hospital is the lead sponsor of 39 studies on the registry; 17 are open to participants now.
