To determine whether mild lung function impairment serves as an independent predictor of lung cancer risk to refine targeted screening strategies.
Analyzed baseline pulmonary function tests, specifically forced expiratory volume in 1 s (FEV1) % predicted, among 3,806 heavy smokers undergoing annual chest computed tomography screening (57 cancer cases, 3,749 non-cancer subjects).
Calculated odds ratios of lung cancer using unconditional logistic regression, controlling for age, sex, study cohort, and smoking variables.
Smokers with FEV1 <90% predicted exhibited higher odds of lung cancer compared to those with FEV1 ≥90% predicted (OR 2.45, 95% CI 1.39–4.33).
Greater impairment with FEV1 <70% predicted was associated with an even higher risk of lung cancer relative to FEV1 ≥90% predicted (OR 2.90, 95% CI 1.34–6.27).
