ReviewLung cancer screening with low-dose computed tomography after the National Lung Screening Trial. The debate is still open.
The aim of this article is to highlight some concerns regarding lung cancer screening with CT through a thorough analysis of scientific literature. The publication of the National Lung Screening Trial in 2011 has revealed that CT screening of smokers and ex-smokers in three annual rounds reduces lung cancer mortality a 20% when compared with thorax x-ray screening. The first limitation of this screening modality is its lack of downstaging in successive screening rounds compared with the initial round. ⋯ Lastly, published studies on lung cancer CT screening are vastly heterogeneous. They include different age groups, different types of smokers and ex-smokers and different tomogram thickness, making the results hardly comparable. In this context we do not recommend lung cancer screening with CT for smokers or ex-smokers outside of the context of individual counseling.
