Dépistage du cancer pulmonaire en Suisse : Qui ? Comment ? Quand ? [Lung cancer screening in Switzerland : Who ? How ? When ?]

Professional societies encourage the establishment of coordinated national screening programs for lung cancer by « low-dose » chest CT scans. The interdisciplinary Swiss Lung Cancer Screening Implementation Group (CH-LSIG) is exploring the feasibility of such a project. However, several questions still remain unanswered, namely the -financing of such a program, the ideal « number-needed to screen », the definition and follow-up of « positive cases », as well as the role of smoking cessation measures. The key points to discuss in the future with patients requesting screening are based on the « shared -decision-making » approach. Pilot projects guided by the CH-LSIG could help to identify the optimal strategy for establishing a national screening program based on the best available scientific evidence
