Lung cancer is one of the leading causes of death in Europe and the USA. A relatively good prognosis is limited to those patients in whom the tumor is detected at an early stage. As clinical symptoms of lung cancer are a late finding in the natural course of the disease, most of the patients are diagnosed at an advanced tumor stage when palliative care remains the only therapeutic option. ⋯ First of all, the population that might benefit from CT lung cancer screening has to be defined precisely. Furthermore, guidelines have to be established about how to manage screening participants with detected lung nodules, as the vast majority of these pulmonary nodules will prove to be benign. This review article summarizes the results of the NLST and the initial data from the European screening trials, and will discuss some of the major open questions in lung cancer screening with CT.
