Hereditary Pancreatitis

RATIONALE: Gathering medical information and collecting and storing samples of blood and tissue to test in the laboratory may help doctors develop better ways to screen people at risk for pancreatic cancer or other pancreatic disorders in the future. PURPOSE: This clinical trial is collecting medical information and tissue samples from patients with pancreatic cancer or other pancreatic disorders.

The diagnosis of hereditary pancreatitis (PH) is based on a genetic criterion - detection of a mutation in the PRSS1 gene or on a genealogical criterion - the presence of chronic pancreatitis in at least 2 first-degree relatives or at least 3 relatives in the second degree, in the absence of other identified predisposing factors (notably chronic alcohol consumption). It is now recommended to seek PH in cases of pancreatitis of unknown origin in a young patient or with a family history. In this study, patients carrying a PRSS1 mutation will be identified from the patient lists of the three French genetics laboratories (Brest University Hospital, Cochin-Paris University Hospital, Lille University Hospital) carrying out PRSS1 gene analysis. Patients will be included by the doctors currently treating them. The aim of the study is to assess the incidence of pancreatic adenocarcinoma in the cohort and describe the natural history of hereditary pancreatitis linked to a mutation in PRSS1.

Pancreatic cancer is one of the most fatal malignancies with a 5-year survival rate of only \~6%\[1\]. The reasons for this high mortality rate can be attributed to several factors, of which perhaps the most important is delayed diagnosis due to vague symptoms and consequently missed opportunities for surgical resection. Therefore, the ability to detect pancreatic cancer at an early, more curable stage is urgently needed. Identifying risk factors and biomarkers of early pancreatic cancer could facilitate screening for individuals at higher than average risk and expedite the diagnosis in individuals with symptoms and substantially improve an individual's chance of surviving the disease. Thus, the investigators propose this longitudinal study entitled, "Artificial Intelligence-based Early Screening of Pancreatic Cancer and High Risk Tracing (ESPRIT-AI)" in order to generate clinical data sets and bank serial blood specimens of high risk individuals.

IRFARPC is a multicenter national registry designed to study the diagnosis and predisposing factors of subjects with an inherited increased risk for pancreatic cancer.
