Low-dose computed tomographic screening for lung cancer.

Low-dose computed tomographic (LDCT) screening is now moving from clinical trials to clinical practice, following the report from the National Lung Screening Trial that LDCT screening for lung cancer can reduce the number of deaths from lung cancer by 20% in current and former smokers, ages 55 to 74 years, with a 30 pack-year smoking history. This article reviews the current evidence for screening, key elements of a successful lung cancer screening clinic, and reporting and management guidelines for LDCT screening findings.
