Who? Familial Pancreas Cancer Screening 1. Peutz-Jeghers Syndrome • At least 30 yrs old 2. Familial pancreaCc cancer relaCves • > 55 years old or 10 years younger than the age of youngest rela7ve with pancrea7c cancer, and • 2 or more members with a history of pancrea7c cancer or one with a first degree rela7ve with PDAC. 3. Germline mutaCon carriers with > 1 pancreaCc cancer in family • 10% + EsCmated lifeCme risk of pancreaCc cancer • FAMMM (p16/CDKN2A), BRCA2, PALB2, ATM muta7on • 5% EsCmated lifeCme risk of pancreaCc cancer • BRCA1, or HNPCC ( hMLH1, hMSH2, PMS1, hMSH6, EpCAM) gene muta7on 4.

Pancrea2c Cancer Screening High Risk Groups • Diabetes Mellitus • Familial Pancrea7c Cancer • Pancrea2c Cysts
Pancrea2c Cysts and Cancer The prevalence of pancrea2c cysts in asymptoma2c individuals is about 2.5-40% • Pseudocyst • Serous cystadenoma • Solid Pseudopapillary Neoplasm (SPEN) • Cys7c pancrea7c endocrine neoplasm (CPEN) • Mucinous cys7c neoplasm • Intraductal Papillary Mucinous Neoplasm (IPMN) Farrell, Fernandez-del Castillo Gastroenterology 2013

Summary • No General Popula7on Screening Indicated • Diabetes • Opportunity for pancreas cancer screening • Pancreas Cancer Screening • Should be performed in high-risk individuals • CAPS5 Study • Aim to find advanced precursor lesions or early PDAC • MRI/MRCP and EUS are main surveillance modali7es • Benefit of a surveillance program remains to be proven!! • Pancrea7c Cysts • High Disease Specific Survival in low risk BDIPMNs • Beter cyst fluid markers for cancer on the way?
