Summary
Background:
- Neuroendocrine tumors (NETs) are rare but have been more common over the past decade. The only treatment for NETs is surgery, but most are found when they are too advanced for surgery. Researchers are looking for the best way to find NETs earlier, so that surgery can be successful. They want to test if the study drug can be used along with imaging devices to detect NETs.
Objectives:
- To see how well a new experimental imaging agent, 68Gallium-DOTATATE, detects unknown primary and metastatic NETs in the gastrointestinal system and pancreas.
Eligibility:
- Adults over 10 years old with a suspected NET or family history of NET.
Design:
* Participants will be screened with a medical history and physical exam, and have a blood test.
* Participants will undergo three scans. For all of these, a substance is injected into their body, they lie on a table, and a machine takes images.
* A standard computed tomography (CT) scan of the chest, abdomen, and pelvis.
* An octreotide scintigraphy Single photon emission computed tomography (SPECT)/CT.
* A 68Gallium-DOTATATE positron emission tomography (PET)/CT. The study drug is injected into a vein, usually in the arm. Low-dose X-rays go through the body. For about 40 minutes a large, donut-shaped device takes images of the body. The entire session takes 90 to 120 minutes.
* Researchers will compare images from the three scans.
* Participants will have 1 follow-up visit each year for 5 years. At this visit, they will have a medical exam, blood taken, and a CT scan.
Eligibility Criteria
- INCLUSION CRITERIA:
- Patients with (any one of #1, #2, and/or #3):
- Suspicion of neuroendocrine tumors (NET) on axial imaging (computed tomography (CT)/magnetic resonance imaging (MRI)/fluorodeoxyglucose (FDG) positron emission tomography (PET) and/or
- biochemical evidence of neuroendocrine tumor (serum/urinary) based on elevated levels of chromogranin A, pancreatic polypeptide, neuron-specific enolase, vasoactive intestinal polypeptide, serotonin (urinary 5-HIAA), gastrin, somatostatin, catecholamines, metanephrines, calcitonin, fasting insulin, C-peptide (proinsulin), glucagon and/or
- familial predisposition to NET in patients with multiple endocrine neoplasia type 1 (MEN1) and Von Hippel-Lindau (VHL) (symptomatic and/or asymptomatic cases; with biochemical or anatomic imaging evidence of disease).
- Age greater than or equal to 10 years of age.
- For females: Negative urine pregnancy test OR post-menopausal for at least 2 years OR patient has had a hysterectomy.
- Patients must be willing to return to National Institutes of Health (NIH) for follow-up.
- Ability of subject or Legally Authorized Representative (LAR) (if the patient is deemed by the treating physician to be cognitively impaired or questionably impaired in such a way that the ability of the patient to give informed consent is questionable) to understand and the willingness to sign a written informed consent document indicating that they are aware of the investigational nature of this study.
EXCLUSION CRITERIA
- Patients unwilling to undergo serial non-invasive imaging.
- Pregnant or lactating women: Pregnant women are excluded from this study because the effects of (68)Ga-DOTATATE in pregnancy are not known. Because there is an unknown but potential risk for adverse events in nursing infants secondary to administration of
(68)Ga-DOTATATE in the mother, breastfeeding should be discontinued for at least one day if the mother receives (68)Ga-DOTATATE.
- Patients that have recognized concurrent active infection,
- Patients with the use of any investigational product or device, excluding 18F-dihydroxyphenylalanine (F-DOPA) scans, within 30 days prior to dosing.
