Model for Individual-Risk–Based CT Screening for Lung Cancer

Computed tomography screening based on personal risk rather than guideline recommendations would prevent more lung cancer deaths.

Based on results of the National Lung Screening Trial (NLST; NEJM JW Gen Med Aug 1 2011 and N Engl J Med 2011; 365:395), the U.S. Preventive Services Task Force (USPSTF) recommends annual screening with low-dose computed tomography (CT) in older adults (age range, 55–80) with ≥30–pack-year smoking histories who smoke currently or have quit within the past 15 years (NEJM JW Gen Med Feb 15 2014 and Ann Intern Med 2014; 160:330). In this analysis, researchers used data from various sources on lung cancer risk factors, incidence, and death to create a more-targeted risk-based model to guide CT lung cancer screening.

Age, sex, race, education, body-mass index, history of emphysema, family history of lung cancer, cigarettes per day, smoking durati…
