- Conditions
- Familial Pancreatic CancerPancreatic AdenocarcinomaPancreatic Intraductal Papillary-Mucinous Neoplasm
- Interventions
- Procedure: Dynamic Contrast-Enhanced Magnetic Resonance Imaging
- Registration Number
- NCT02070705
- Lead Sponsor
- OHSU Knight Cancer Institute
- Brief Summary
This clinical trial studies an imaging technique known as dynamic contrast enhanced magnetic resonance imaging (DCE MRI) in identifying the presence of pancreatic cancer. DCE MRI is a procedure that takes detailed pictures of functional and structural properties inside the body using magnetic field imaging. These images may better characterize pancreatic cancer in patients at high risk or in patients who may have undergone chemotherapy for pancreatic cancer.
- Detailed Description
PRIMARY OBJECTIVES:
I. Assess the ability of DCE-MRI to identify the presence of pancreatic cancer in patients at high risk for hereditary pancreatic cancer.
II. Assess the ability of DCE-MRI to identify the presence of pancreatic cancer in patients with cystic lesions of the pancreas.
III. Assess the ability of DCE-MRI to accurately predict tumor margins in patients who have undergone chemotherapy for pancreatic cancer.
IV. Obtain DCE-MRI scans of from healthy volunteers (Group 4), to establish baseline imaging parameters of the normal, non-diseased pancreas for use as a comparator to affected pancreata.
SECONDARY OBJECTIVE:
I. Clinical factors associated with the presence of pancreatic cancer will be assessed in each of the three experimental groups, including disease free survival and overall survival.
II. Additional MRI pulses sequences (e.g. MR fingerprinting, etc.) will be acquired for the assessment of tissue contrast before and after the administration of contrast agents.
OUTLINE: Patients are assigned to 1 of 4 groups.
ARM I (High-risk for familial or hereditary pancreatic cancer): Patients undergo DCE MRI yearly for a minimum of 3 scans.
ARM II (Intraductal papillary mucinous neoplasms \[IPMN\]): Patients undergo DCE MRI prior to surgery for resection of IPMN.
ARM III (Pancreatic cancer): Patients who undergo chemotherapy prior to resection will have 2 DCE MRI scans; one study scan prior to undergoing neoadjuvant therapy, as well as one study scan following neoadjuvant therapy as part of their pre-operative work up in addition to the standard imaging studies. For patients that do not require chemotherapy treatment prior to resection they will have just one DCE MRI scan prior to surgical resection. Patients currently undergoing neoadjuvant therapy or who have already completed neoadjuvant therapy that were unable to undergo imaging at baseline and are now proceeding to resection will have one DCE MRI scan prior to surgical resection.
ARM IV (Healthy volunteers): Patients undergo a single DCE MRI examination.

-
HEALTHY VOLUNTEERS (Group 4): Must meet inclusion criteria for "all participants" described above
-
HEALTHY VOLUNTEERS (Group 4): Group 4 participants must have no history of cancer, pancreatic disease, or family history of pancreatic cancer.
- Family history will be defined as pancreatic cancer occurring in one first-degree relative and two other relatives, or two first-degree relatives
- Participants unable or unwilling to give written, informed consent or to undergo MRI imaging
- Participants with multiple drug allergies, and/or subjects who have had an allergic reaction to any intravenous iron replacement product, or a known history of hypersensitivity to ferumoxytol
- Participants with concurrent clinical diagnosis, evidence of suspected hemochromatosis, or other diseases of iron metabolism (i.e., iron overload)
- Cirrhosis, cardiomyopathy, restrictive heart disease, or bronzing of the skin
- Pregnant women are excluded from this study because there is an unknown, but potential risk, for adverse events, as small animal trials have linked ferumoxytol administration (at very high doses) to birth defects (e.g., soft-tissue malformations and decreased fetal weights); it is not known whether ferumoxytol is present in human milk; breastfeeding, however, should be discontinued if the mother receives ferumoxytol while nursing
- Human immunodeficiency virus (HIV)-positive participants on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with ferumoxytol
- Participants with diagnosis of renal insufficiency or glomerular filtration rate (GFR) < 60 ml/min/1.73m^2
- Adult patients who require monitored anesthesia for MRI scanning
- Participants with any contraindications to gadolinium-based contrast agents
- Participants who have a contraindication for MRI (e.g. metal in their bodies, a cardiac pacemaker, or other incompatible device), or are severely agitated or claustrophobic. (For patients that are eligible but there is a concern of metal in their bodies, the will be given the option if interested to have a x-ray completed prior to study enrollment to determine if they can proceed with the study MRI. Patients with a concern of metal in their bodies that don't agree to a x-ray will not be enrolled into the study.)
