Abstract: Introduction: Surveillance programs on high-risk individuals (HRIs) can detect premalignant lesions or early pancreatic cancer (PC). We report the results of the first screening round of the Italian multicenter program supported by the Italian Association for the study of the Pancreas (AISP). Methods: The multicenter surveillance program included asymptomatic HRIs with familial (FPC) or genetic frailty (GS: BRCA1/2, p16/CDKN2A, STK11/LKB1 and PRSS1) predisposition to PC. The surveillance program included at least an annual magnetic resonance cholangiopancreatography (MRCP). Endoscopic ultrasound (EUS) was proposed to patients who refused or could not be submitted to MRCP. Results: One-hundreds eighty-seven HRIs underwent a first-round screening examination with MRCP (174;93.1%) or EUS (13;6.9%) from September 2015 to March 2018.The mean age was 51 years (range 21-80).One-hundreds sixty-five (88.2%) FPC and 22 (11.8%) GF HRIs were included. MRCP detected 27 (21.9%) presumed branch-duct intraductal papillary mucinous neoplasms (IPMN), 1 invasive carcinoma/IPMN and one low-grade mixed-type IPMN, respectively. EUS detected 4 PC (2.1%): 1 was resected, 1 was found locally advanced intraoperatively and 2 were metastatic. Age>50 (OR 3.3, 95%CI 1.4-8), smoking habit (OR 2.8, 95%CI 1.1-7.5), and having >2 relatives with PC (OR 2.7, 95%CI 1.1-6.4) were independently associated with detection of pre-malignant and malignant lesions. The diagnostic yield for MRCP/EUS was 20.3% for cystic lesions. The overall rate of surgery was 2.6% with nil mortality. Discussion: The rate of malignancies found in this cohort was high (2.6%). According to the International Cancer of the Pancreas Screening Consortium the screening goal achievement was high (1%).
