Impact of Behavior Modification Interventions and Lung Cancer Screening on Smoking Cessation in People Living With HIV: A Feasibility Study

This feasibility study is testing whether a combination of lung cancer screening (using low-dose CT scans) and smoking cessation support through a smartphone app can help people living with HIV (who face a higher lung cancer risk) to quit smoking. The study is exploring whether this approach is practical and acceptable in this population. **You may be eligible if...** - You are living with HIV and between 45 and 80 years old - You are currently a smoker (confirmed by a breath test) - You have a significant smoking history (20+ pack-years) and meet criteria for lung cancer screening - You are on HIV treatment with a CD4 count of at least 200 cells/uL - You own a smartphone compatible with the study app - You can read at a basic level (assessed by a short literacy test) **You may NOT be eligible if...** - You are currently using or recently used (within 30 days) other smoking cessation treatments - You have had lung cancer before - You are pregnant or breastfeeding - You have had a serious lung infection in the past 3 months - You have had a chest CT scan in the past 12 months - You have an uncontrolled serious illness or condition that limits your life expectancy or ability to participate Talk to your doctor to see if this trial is right for you.
