At study enrollment and prior to any pancreatic surgery and prior to or at least 3 days after the most recent GI endoscopy procedure, approximately 50 ml (10 teaspoons) of blood will be drawn from all participants and be processed according to standardized study biospecimen protocol. Serial blood collection will be offered to all the participants depending on the subjects' tier classification. Blood draw will be completed at Mayo Clinic when the subjects come back, or study blood draw kit may be sent for external collection.

This may be collected from research subjects every time they are undergoing a clinically indicated endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography (ERCP) or upper gastrointestinal endoscopy (EGD) procedure. Pancreatic juice will not be collected if PI or provider determines it is not in the best interest of the subject. Pancreatic juice collection will be performed prior to fine needle aspiration (FNA), brushing or stent placements if performed during the same endoscopic procedure.

A research MRI with contrast that includes a Magnetic Resonance Cholangiopancreatography (MRCP) will be offered to patients in the Tier 2 cohort at baseline and at 3-year intervals if not done as standard of care. Gadolinium based intravascular contrast will be administered for this procedure. Sedation for claustrophobia/anxiety per clinical protocol will be an option if the patients requested. Subject would be notified of any concerning results. A safety questionnaire will be completed by the study team before ordering the MRI. Clinically indicated MRIs for the TIER 1 participants will be used and collected as part of the registry. If a clinical MRI/MRCP has been performed between 0 to 3 months before obtaining consent, the prior clinical MRI/MRCP could be used to obtain baseline imaging data.
