Secretin-enhanced Magnetic Resonance Cholangiopancreatography (S-MRCP) and Pancreatic Function Following Surgery

April 3, 2015 updated by: Columbia University

MRCP With Secretin Stimulation for the Evaluation of Pancreatic Endocrine and Exocrine Function Following Surgical Resection for Pancreatic Adenocarcinoma

The aim of this study will be to determine whether secretin-enhanced MRCP (S-MRCP) as well as traditional magnetic resonance imaging (MRI) of the pancreas will allow the investigators to quantify the pancreas' ability to secrete hormones as well as digestive enzymes, both before and after surgery. The investigators hypothesize that S-MRCP will provide a novel non-invasive measure of pancreatic function.

Detailed Description

Surgical resection offers the only hope of cure for pancreatic adenocarcinoma. While perioperative mortality rates have declined in recent years, pancreatectomy is still associated with significant postoperative malnutrition, maldigestion, and glucose intolerance, mostly as a result of pancreatic insufficiency. Quantifying residual pancreatic function remains a challenge, but is essential in improving the survival and quality of life of pancreatic cancer patients. Secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP)has recently emerged as a widely-accepted noninvasive technique to assess morphological changes in the pancreatic ducts, as well as functional secretory capacity of the gland. The aim of our study is to evaluate S-MRCP as a means to assess pancreatic reserve in patients who will undergoing surgical resection for pancreatic carcinoma. As an adjunct to S-MRCP, we will also evaluate the concomitant use of dynamic MRI with contrast enhancement. This will be a prospective study of twelve patients who will undergo S-MRCP/MRI within 30 days of surgery and then at 3, 6, and 12 months post-operatively. Quantitative analysis of S-MRCP will include pancreatic duct diameter and volume before and after secretin administration. MRI will be analyzed for mean T1 signal intensity, total parenchymal volume, and gadolinium enhancement. These radiological parameters will be compared to clinical parameters of exocrine function(subjective reporting of steatorrhea and abdominal pain as well as levels of fecal elastase1 and fat soluble vitamins in stool samples) as well as endocrine function (fasting blood glucose, hemoglobin A1c, amylin, glucagon, and somatostatin levels, as well as arginine-stimulated levels of islet cell hormones).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Secretin
One-arm (open label): Synthetic Human Secretin. Patients will undergo four Secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) evaluations.
Drug: Synthetic Human Secretin
S-MRCP has recently emerged as a widely-accepted noninvasive technique to assess morphological changes in the pancreatic ducts, as well as functional secretory capacity of the gland. Twelve patients will each undergo four Secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) evaluations, at a dose of 0.2 ucg/kg per exam, each S-MRCP will require 16-32 ucg of secretin (12 vials). Secretin, provided by the Repligen Corporation, will be administered by IV bolus injection over 30 seconds followed by a 30 second saline flush. The maximum dose of secretin will be 18.5 ucg.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percent of duct volume change of patients with bicarbonate concentration of duodenal fluid aspirate or acid steatocrit
Time Frame: 12 months
Our primary aim is to compare S-MRCP with either Endoscopic Pancreatic Function Test (ePFT) (in those patients who undergo esophagogastroduodenoscopy [EGD] or endoscopic ultrasound [EUS]) or acid steatocrit. The primary outcome will be the correlation between duodenal filling on SMRCP (expressed as percent of duct volume change from baseline and maximal values following secretin administration) with either 1) maximal bicarbonate concentration of duodenal fluid aspirate or 2) acid steatocrit (a measure of steatorrhea, expressed as volumetric percentage).
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage diameter change on S-MRCP of patients with pancreatic insufficiency
Time Frame: 12 months
In those patients who are undergoing endocrine pancreatic testing, our secondary aim is to investigate the relationship between other radiological parameters, including percentage diameter change on S-MRCP, with other clinical markers of pancreatic insufficiency, including fecal elastase-1 and vitamin levels, patients' grading of abdominal symptoms, quality-of-life questionnaire scores, and body mass index (BMI).
12 months
Pancreatic duct mean diameter of patients with high arginine-stimulated hormone levels
Time Frame: 12 months
Another secondary aim will be to evaluate MRI imaging parameters (primarily maximal gadolinium signal enhancement, but also non-enhancement measures such as total volume and mean T1 signal) with arginine-stimulated hormone levels (primarily arginine-stimulated insulin levels, but we will also be examining glucagon, amylin, somatostatin and Cpeptide levels).
