Lung Cancer Screening Debate Continues Despite International CT Study Results

Abstract

Earlier this year, a lung cancer screening study received worldwide press when it found that computed tomography (CT) screening of patients at risk for lung cancer can lead to early detection. But the disputed report has not reduced the distance between two sparring groups of researchers. The critical issue is whether CT screening can reduce lung cancer deaths: the ultimate test of any effective cancer screening. Can a screening clinical trial with no control arm can prove a reduction in mortality? This study, the International Early Lung Cancer Action Program (I-ELCAP), had no control arm. Investigators
