Brief Summary:
Our previous study had proven that LDCT led to a 74.1% increase in detecting early-stage lung cancer compare to usual care (NCT02898441). The present one arm study is performed to validate our previous findings and optimize the screening procedure. 6000 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.

Arm Intervention/treatment
LDCT Screening
LDCT was performed at baseline + 2 biennial repeated LDCT rounds
Device: Low Dose Computed Tomography
LDCT were performed in screening arm. The abnormal nodules were defined as noncalcified nodules (NCN) larger than 5 mm

Primary Outcome Measures :
  1. Lung cancer incidence rate [ Time Frame: 5 years ]
    Assess the number of lung cancer incidences after each round of screening

  2. Lung cancer mortality [ Time Frame: 5 years ]
    Assess lung cancer mortality within next 5 years after first round of screening

Secondary Outcome Measures :
  1. All-cause mortality [ Time Frame: 5 years ]
    Assess all-cause mortality within next 5 years after first round of screening

  2. Nodule detection rate [ Time Frame: 1 year ]
    Assess nodule detection rate, and the types and sizes of nodules detected in LDCT screening arm
