Molecular Detection of Advanced Neoplasia in Pancreatic Cysts
- Conditions
- Pancreas Cyst
- Interventions
- Diagnostic Test: Blood, stool, pancreatic juice and cyst fluid collectionProcedure: Pancreatic SurgeryProcedure: Endoscopy Exam
- Registration Number
- NCT03855800
- Lead Sponsor
- Mayo Clinic
- Brief Summary
Researchers are trying to find out whether new tests ("biomarkers") of blood, stool, pancreas cyst fluid, or pancreas juice can be used to diagnose malignant or pre-malignant changes in pancreas cysts.
- Detailed Description
Subjects with Fukuoka Worrisome (FW) or Fukuoka High Risk (FHR) pancreatic cysts will be enrolled and assigned to Immediate Surgery or Clinical Follow-up groups based on clinical management as determined by the treating physicians. Blood, stool, pancreas cyst fluid, and pancreas juice specimens will be collected from participants.

Group Intervention Description Clinical Follow-up Blood, stool, pancreatic juice and cyst fluid collection Participants not undergoing surgery will be assigned to the "Clinical Follow-up" study group. Blood, stool, pancreatic juice and cyst fluid collection will be done as per protocol. All participants in the Clinical Follow-up group will be contacted yearly for a telephone interview until they undergo surgery, die, receive a diagnosis that excludes them from the study, or for 5 years, and interval medical records will be obtained and reviewed. During follow-up results of clinically indicated follow-up imaging studies will be abstracted Surgical Blood, stool, pancreatic juice and cyst fluid collection Participants scheduled for surgical resection after their initial clinical evaluation will be assigned to the "Immediate Surgery" study group. Blood, stool, pancreatic juice and cyst fluid collection will be done as per protocol. Participants in the Immediate Surgery group will be followed until the surgical pathology of their pancreatic cyst is known. Surgical Pancreatic Surgery Participants scheduled for surgical resection after their initial clinical evaluation will be assigned to the "Immediate Surgery" study group. Blood, stool, pancreatic juice and cyst fluid collection will be done as per protocol. Participants in the Immediate Surgery group will be followed until the surgical pathology of their pancreatic cyst is known. Clinical Follow-up Endoscopy Exam Participants not undergoing surgery will be assigned to the "Clinical Follow-up" study group. Blood, stool, pancreatic juice and cyst fluid collection will be done as per protocol. All participants in the Clinical Follow-up group will be contacted yearly for a telephone interview until they undergo surgery, die, receive a diagnosis that excludes them from the study, or for 5 years, and interval medical records will be obtained and reviewed. During follow-up results of clinically indicated follow-up imaging studies will be abstracted
- Primary Outcome Measures
Name Time Method Biospecimen Acquisition 5 years Number of biospecimens collected
High grade dysplasia (HGD) or cancer diagnosis in Immediate Surgery group 5 years To validate the diagnostic accuracy of cyst fluid methylated DNA marker (MDM) assays for detection of HGD and cancer in pancreatic cysts undergoing surgical resection
- Secondary Outcome Measures
Name Time Method High grade dysplasia (HGD) or cancer diagnosis in clinical follow up group 5 years To evaluate the performance of cyst fluid MDM assays for predicting development of HGD or cancer during 3-year follow-up in study patients who are initially managed non-operatively
