Table 2. Recommendations From the American College of Chest Physicians and the American Society of Clinical Oncology on the Role of CT Screening for Lung Cancer.

Recommendation #1

Annual screening should be offered over both annual screening with chest radiograph or no screening to smokers and former smokers aged 55 to 74 who have smoked for 30 pack-years or more and either continue to smoke or have quit within the past 15 years. Screening should only be done by centers that can deliver the evaluation and care provided to National Lung Screening Trial (NLST) participants. (Grade of recommendation:2B.)

Recommendation #2

No CT screening should not be performed for individuals who have accumulated fewer than 30 pack-years of smoking are either younger than 55 years or older than 74 years, or for individuals who quit smoking more than 15 years ago, or for individuals with severe comorbidities that would preclude potentially curative treatment and limit life expectancy. (Grade of recommendation:2C.)
