Defining the path: lung cancer CT screening in Europe

Since the publication of the National Lung Screening Trial (NLST) in 2011 demonstrating a 20% reduction in lung cancer-specific mortality by annual low-dose CT (LDCT),1 implementation of screening has continued apace in the USA. Other developed nations, perhaps mindful of the potential cost implications of national screening programmes, have been more reticent, with many awaiting the final outcome data from the largest European randomised trial—the Dutch-Belgian Lung Cancer Screening trial (NELSON)  study which remains in follow-up.2

Despite the convincing mortality reduction in NLST, questions remain about implementation of LDCT screening for lung cancer. Unresolved issues include how to best identify high-risk individuals for screening, what is the most appropriate screening interval to achieve an optimal balance between mortality reduction and cost-effectiveness and how to minimise possible harms associated with screening—particularly overdiagnosis. This issue of Thorax includes two papers which provide important additions to accumulating evidence in this...
