One-fifth of LDCT detected lung cancers are indolent

Researchers used data from the National Lung Screening Trial (NLST), a randomised trial comparing screening using LDCT versus chest radiography (CXR) among 53,452 people considered at high risk for lung cancer. Patients were considered high risk if they had smoked an equivalent of a pack of cigarettes a day for 30 years and were observed for 6.4 years.
