简要总结
CLUS version 1.0, had proven that LDCT led to a 74.1% increase in detecting early-stage lung cancer compare to usual care (NCT02898441). CLUS version 2.0 evaluated the efficacy of new techniques (AI, AFI and MTB) in fostering the implementation of lung cancer screening (NCT03975504). The present multi-center study is performed to evaluate the effectiveness of different lung cancer screening strategy and validate our previous findings. 100,000 high-risk subjects (age 45-75) were recruited to take LDCT screening (Baseline + 2 biennial repeated LDCT screening). Follow-up for lung cancer incidence, lung cancer mortality and overall mortality was performed. Blood samples were stored in a Biobank. Management of positive screening test was carried out by a pre-specified protocol.
