China Lung Cancer Screening (CLUS) Study Version 3.0

August 7, 2022 updated by: Baohui Han, Shanghai Chest Hospital

Lung Cancer Screening With Low-dose CT in China (CLUS Study) Version 3.0

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Whole-process management strategy

High-risk individuls are provided with whole-process management strategy, including lung cancer education, decision-making, assisting in making and attending LCS LDCT appointments, arranging follow-up when needed, tobacco cessation support for smokers, treatment assistance if diagnosed as lung cancer.

LDCT was performed at baseline + 2 biennial repeated LDCT rounds.

Enrolled participants will managed by a pre-designed software. The software would provide helpful assistance, such as lung cancer education, decision-making, assisting in making and attending LCS LDCT appointments, arranging follow-up when needed, tobacco cessation support for smokers, treatment assistance if diagnosed as lung cancer.
LDCT were performed in both arm. The abnormal nodules were defined as noncalcified nodules (NCN) larger than 5 mm
Active Comparator: Rountine screening strategy
LDCT was performed at baseline + 2 biennial repeated LDCT rounds.
LDCT were performed in both arm. The abnormal nodules were defined as noncalcified nodules (NCN) larger than 5 mm
