American Lung Association Recommends CT Screening for Lung Cancer in High-Risk Patients
The American Lung Association is now recommending that high-risk smokers receive low-dose CT scans to screen for lung cancer. The ALA's interim guidelines follow publication of results from the National Lung Screening Trial (NLST), which found reduced lung cancer mortality among patients randomized to low-dose CT screening, compared with those given chest x-rays.
The ALA recommends low-dose CT screening for patients meeting the following four NLST criteria:
- Current or former smokers
- Age 55 to 74
- Smoking history of at least 30 pack-years
- No history of lung cancer
The general population should not be screened for lung cancer with low-dose CT scans, and chest x-rays are not recommended for lung cancer screening.
