Lung cancer is responsible for one in five cancer-related deaths. Screening for lung cancer using low-dose chest CT (LDCT) is supported by several international studies targeting the at-risk population as part of an organised programme. Given the organisational challenges for the healthcare systems of the countries concerned, this involves setting up pilot screening projects. This requires close collaboration between the players involved, with a multidisciplinary approach structured around the participant, aiming to offer the expertise of the pulmonologist and the radiologist on the LDCT performed, interpreted with the help of artificial intelligence. Here we set out the elements needed to develop a screening programme, starting with the implementation of a pilot project.
