¹MRI yield is defined as detection of any lesions morphologically suspicious for BD-IPMN or histologically proven (pre) malignant lesion (PanIN ≥ 2, IPMN and pancreatic adenocarcinoma) at baseline evaluation and, when performed, during the follow up;

²Treatment is considered a success if any of the following lesions is found at surgery: resectable PDAC, MD-IPMN or IPMN with dysplasia, PanIN3. FPC: Familial pancreatic cancer; BD: Branch duct; MD: Main duct; IPMN: Intraductal papillary mucinous neoplasm; PDAC: Pancreatic ductal adenocarcinoma; PJS: Peutz–Jeghers syndrome; PanIN: Pancreatic intraepithelial neoplasia; FAMMM: Familial atypical multiple mole melanoma; FBOC: Familial breast ovarian cancer; HP: Hereditary pancreatitis.
