The Johns Hopkins Lung Project was a two-arm randomly assigned study designed to determine whether the addition of cytologic screening to the radiographic screening of at-risk volunteers (Male smokers 45 or older) could enhance the early detection of asymptomatic lung cancer and whether early therapeutic intervention in detected cases could significantly reduce the mortality from this disease.
