Summary of recommendations for screening for lung cancer from Canada and elsewhere

OrganizationRecommendation
Canadian Task Force on Preventive Health Care (current)Screen asymptomatic adults aged 55 to 74 years with at least a 30 pack-year smoking history who smoke or quit smoking less than 15 years ago for lung cancer with low-dose CT every year for 3 consecutive years
Canadian Task Force on Preventive Health Care (2003)5Do not screen asymptomatic adults for lung cancer with chest radiography; insufficient evidence for using low-dose CT as a screening test for asymptomatic adults
US Preventive Services Task Force (2013)4Screen asymptomatic adults aged 55 to 80 years with a minimum 30 pack-year smoking history who smoke or quit smoking within the last 15 years for lung cancer with low-dose CT annually
Cancer Care Ontario (2013)26Screen high-risk populations (i.e., adults 55–74 yr of age with a minimum smoking history of 30 pack-years or more who currently smoke or quit smoking within the past 15 yr and are free of disease at the time of screening) for lung cancer with low-dose CT for 3 years followed by biennial screening
American Cancer Society (2013)27Screen adults aged 55 to 74 years with a 30 pack-year or more smoking history who smoke or quit smoking within the previous 15 years and are in relatively good health for lung cancer with low-dose CT annually
American College of Chest Physicians (2013)28Screen adults aged 55 to 74 years with a 30 pack-year or more smoking history who smoke or quit smoking within the previous 15 years for lung cancer with low-dose CT annually
American Lung Association (2012, updated 2015)29Screen adults aged 55 to 74 years with a smoking history of at least 30 pack-years and no history of lung cancer who smoke or quit smoking with the last 15 years for lung cancer using low-dose CT annually
American Association for Thoracic Surgery (2012)30Screen adults aged 55 to 79 years with a 30 pack-year or more smoking history; adults with a previous diagnosis of lung cancer who have completed 4 years of surveillance without recurrence, and who can tolerate lung cancer treatment following screening to detect second primary lung cancer until the age of 79 years; and adults aged 50 to 79 years with a 20 pack-year smoking history and an additional comorbidity that produces a cumulative risk of lung cancer of 5% or more in 5 years for lung cancer with low-dose CT annually
National Comprehensive Cancer Network (2015)31Screen adults aged 55 to 74 years with a 30 pack-year or more smoking history who quit smoking less than 15 years ago, and adults aged 50 years or older with a 20 pack-year or more smoking history and 1 additional risk factor (other than exposure to second-hand smoke) for lung cancer with low-dose CT annually
American Academy of Family Physicians (2013)32Insufficient evidence to recommend for or against screening for lung cancer with low-dose CT
  • Note: CT = computed tomography.
