Conditions
Outcome Measures
Primary Outcomes (1)
Positive Predictive Value (PPV) of Screening Strategies
Proportion of true lung cancer cases among participants with positive screening results, confirmed by histopathology within 3 months after screening. Calculated as: (True Positives) / (True Positives + False Positives) × 100%. Assessed separately for both screening arms.
From enrollment through completion of diagnostic confirmation (up to 3 months post-screening)
Secondary Outcomes (6)
Sensitivity of Screening Strategies
From screening to 12-month follow-up
Specificity of Screening Strategies
From screening to 12-month follow-up
Negative Predictive Value (NPV)
From screening to 12-month follow-up
Early-Stage Shift Proportion
At time of cancer diagnosis (within 3 months post-positive screening)
Lung Cancer-Specific Mortality Rate
From randomization to 3-year follow-up

Interventions
Lung cancer risk stratification via prediction model integrating: advanced age, lung cancer family history, personal cancer history, childhood coal exposure, asthma history, and food allergy history. High-risk individuals receive LDCT screening. Thoracic physicians guide management of screen-positive cases.
Participants are screened based on NCCN guideline criteria. High-risk individuals receive LDCT screening. Thoracic physicians guide management of screen-positive cases.
Eligibility Criteria
You may qualify if:
- Residents with local household registration residing continuously in the region for ≥3 years.
- Aged 40-74 years at enrollment.
You may not qualify if:
- Prior diagnosis of lung cancer (histologically/cytologically confirmed)
- Currently receiving active treatment for any malignancy.
- Presence of severe comorbidities with life expectancy \<5 years
- Participation in any lung cancer screening program within 5 years.
- Functional dependency (ADL score ≤2) OR unwillingness to comply with protocol-required follow-up.
- Declined to provide written informed consent.
