Prospective Screening for Pancreatic Ductal Adenocarcinoma in High-Risk Individuals

Inclusion Criteria: Participants must meet any of the following: * Individuals with pathogenic/likely pathogenic germline variants in STK11, and age ≥30 years.Age * Individuals with pathogenic/likely pathogenic germline variants in CDKN2A, and age ≥40 years (or 10 years younger than the earliest exocrine pancreatic cancer diagnosis in the family, whichever is earlier). * Individuals with pathogenic/likely pathogenic germline variants in one of the other pancreatic cancer susceptibility genes (ATM, BRCA1, BRCA2, MLH1, MSH2, MSH6, EPCAM, PALB2, TP53), and age ≥50 years (or 10 years younger than the earliest exocrine pancreatic cancer diagnosis in the family, whichever is earlier) AND • Exocrine pancreatic cancer in ≥1 first- or second-degree relative from the same side of (or presumed to be from the same side of) the family as the identified pathogenic/likely pathogenic germline variant. * Individuals with pathogenic/likely pathogenic variants in PRSS1 AND a clinical phenotype consistent with hereditary pancreatitis, and age ≥40 years (or 20 years after onset of pancreatitis, whichever is earlier). * Individuals with familial pancreatic cancer including: * Family history of exocrine pancreatic cancer in ≥2 first-degree relatives from the same side of the family, even in the absence of a known pathogenic/likely pathogenic germline variant, OR * Family history of exocrine pancreatic cancer in 1 affected first-degree relative and 1 second-degree relative, even in the absence of a known pathogenic/likely pathogenic germline variant, OR * Family history of exocrine pancreatic cancer in ≥3 first- and/or second-degree relatives from the same side of the family, even in the absence of a known pathogenic/likely pathogenic germline variant. * Individuals who are undergoing clinically recommended pancreatic cancer surveillance. Exclusion Criteria: * Individuals with active or prior pancreatic ductal adenocarcinoma diagnosis.Prior malignancy * Individuals with any active metastatic cancer. * Individuals who are unable to give informed consent. * Individuals who are under the age of 18 (infants, children, teenagers). * Individuals unable to tolerate Magnetic Resonance Imaging/Magnetic Resonance Cholangiopancreatography and Endoscopic Ultrasound. * Pregnant women are unlikely to be undergoing screening procedures and will not be considered eligible but can consent to the study at a later date.Pregnancy
