Randomized Controlled TrialLung Cancer Risk and Demographic Characteristics of Current 20-29 Pack-year Smokers: Implications for Screening.
Based on current recommendations, 30+ pack-years of smoking are required for eligibility for low-dose CT (LDCT) lung cancer screening; former smokers must have quit within 15 years. We investigated whether current smokers with 20 to 29 pack-years have similar lung cancer risks as eligible former smokers and also whether they have a different demographic profile. ⋯ The potential benefits and harms of recommending LDCT screening for 20 to 29-pack-year current smokers should be assessed.
