In 2013, the US Preventive Services Task Force (USPSTF) recommended annual lung cancer screening with low-dose computed tomography (CT) in US adults aged 55 to 80 years who currently smoke or formerly smoked with a 30 pack-year history, and for those who formerly smoked, quitting within the past 15 years (grade “B” recommendation).1 In this issue of JAMA, the USPSTF updates this recommendation, proposing 2 significant changes, both related to the population recommended to undergo screening. The first change reduces the age at which to initiate annual screening from 55 to 50 years. The second change reduces the smoking intensity from 30 to 20 pack-year history. Thus, the USPSTF now “recommends annual screening for lung cancer with LDCT [low-dose CT] in adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery. (B recommendation)”2
