Three-year findings of an early lung cancer detection feasibility study with low-dose spiral computed tomography in heavy smokers.

Background: Low-dose spiral computed tomography (sCT) showed a four-fold increase in the detection rate in high-risk subjects and a higher percentage of stage I lung cancer in comparison with chest X-ray. However, there is a considerable discrepancy among studies in the percentage of lung nodules, overall lung cancer and stage I detection rate.

Subjects And Methods: From April to December 2001, 520 asymptomatic volunteers aged >or=55 years with a history of cigarette smoking >or=20 pack-years and no previous cancer were enrolled to receive an annual sCT of the chest for five consecutive years.
