Abstract

With the results of the National Lung Screening Trial (NLST) showing a reduction in lung cancer mortality of 20 % when comparing chest CT to chest radiography, a new dawn has broken in the fight against lung cancer. Until this news, there was no proven method for early detection of lung cancer, and the primary tool was the difficult proposition of smoking cessation. While smoking cessation reduces the risk of developing lung cancer, up to 50 % of newly diagnosed lung cancers occur in former smokers. In addition, once diagnosed, the burden of lung cancer on the healthcare system is tremendous with an estimated cost of treating lung cancer in the United States in 2004 of $9.6 billion dollars. All of this points to a need for effective early detection and treatment that can save both lives and costs. While the NLST confirms the scientific basis of screening, there are certainly questions about feasibility and cost that still dominate the policy discussion.
