AAFP = American Academy of Family Physicians; CHEST = American College of Chest Physicians; CMS = Centers for Medicare and Medicaid Services; LDCT = low-dose helical CT; NLST = National Lung Screening Trial; PLCO = Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial; SDM = shared decision making.
↵a Shared decision making endoresed or implied.
↵b Other NCCN risk factors include radon exposure, occupational exposure, history of cancer, family history of lung cancer, COPD, and pulmonary fibrosis.
↵c People aged 55-79 years with ≥30 pack-year of smoking history or people aged 50-79 years with ≥20 pack-year of smoking history with personal lung cancer history or another risk factor such as COPD, environmental or occupational exposure, prior cancer or radiation therapy, genetic predisposition or family history.
d Insufficient evidence to recommend screening. Screening cannot be recommended on the basis of a single study conducted in major medical centers.
