To present the rationale and study design of the National Lung Screening Trial evaluating whether low-dose helical computed tomography reduces lung cancer mortality compared with chest radiography.
Multicenter randomized controlled trial design comparing low-dose helical computed tomography with standard chest radiography.
Target population consists of older current and former heavy cigarette smokers at high risk for lung cancer.
Lung cancer-specific mortality is designated as the primary endpoint to avoid confounding from lead-time, length, and overdiagnosis biases.
Numerical outcome data are not reported in this protocol and design paper.
Establishes a rigorous clinical trial framework capable of definitively proving whether early detection translates to a reduction in lung cancer mortality.
