Hong kong study to test CT screening for lung cancer in 15,000 heavy smokers
NCT ID NCT07478757
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether low-dose CT scans can help find lung cancer early in high-risk smokers aged 50-79 in Hong Kong. About 15,000 participants will be randomly assigned to receive three rounds of CT scans or usual care. The main goal is to see if screening reduces lung cancer deaths over up to 10 years.
