      Lung cancer is the leading cause of cancer death worldwide. Two large randomized controlled trials (NLST,NELSON) founded a significant decrease in lung cancer mortality with an annual low dose CT screening among selected current or former smockers.While being now recommended in many countries, the French National Authority for Health claimed that conditions were not sufficient for implementation of such a screening program in France. The aims of our study were to assess the feasibility and effectiveness of a lung cancer screening pilot program with LD CT scan in a French department. We report here the results of the first screening round.

      DEP KP80 was a single-arm, prospective study started in May 2016 and ended in December 2018 in a French department (Somme). The inclusion criteria were those of the NLST study. An annual LD CT scan was scheduled and 2 rounds were planned. Our algorithms considered nodules<5mm as negative, nodules> 10mm as positive and recommended a 3-month CT with measurement of the doubling time for nodules between 5 and 10 mm . Smoking cessation was encouraged as part of the protocol. This study was managed by the departmental cancer screening agency (ADEMA80). All General Practitioners (GP), pulmonologists (PN) and radiologists from the department were solicited by mail to participate in this study. Subjects were selected by GP or PN who checked the inclusion criteria and precribed the CT scan.

      218 GP, 17 PN and 28 radiologists accepted to participate. Over a 2.5 years period, 1307 subjects were recruited. the participation rate was of 73% (949 scans were performed). Screening was negative in 733 cases (77%), positive in 54 (5.7%) and indeterminate in 162 (17%). The prevalence of a detected lung cancer was 2.5% : 24 cancers with 16 adenocarcinomas,3 squamous cell carcinomas, 1 carcinoid tumour, 2 small cell carcinomas 1 undetermined and 1 unknown. There were 2 carcinoma in situ (8%),13 Stage IA (54%), 3 Stage IIB (12%), 2 Stage IIIA (8%) and 4 Stage III B,C (17%). A surgery was performed in 20 of these patients (83%) and one patient underwent surgery for benign lesion.

      This study demonstrates, at a regional level, the feasibility and effectiveness of an organized and structured lung cancer screening by LD CT scan in France.
