After decades of relatively unsuccessful attempts to improve survival for patients with lung cancer, CT screening has changed the scene. After publication of the results from a pioneering non-randomised pilot study,¹ one large-scale randomised controlled trial in the USA and seven European randomised controlled trials were designed to investigate whether earlier detection of lung cancer—made possible primarily by following up after detection of a high quantity of CT-visible pulmonary nodules in high-risk people, which had not yet given rise to complaints—could be followed by earlier, more effective treatment.
