简要总结
Background:
People with von Hippel-Lindau (VHL) can have problems with a variety of organs, such as the pancreas. The disease can cause tumors of the pancreas. This can result in life-threatening complications. Researchers want to learn more about these pancreatic tumors and how to better detect them. This may help them design better future treatment and care for people with VHL disease.
Objective:
To better understand VHL disease that affects the pancreas and to test whether adding a certain type of scan (68-Gallium DOTATATE PET/CT) can further detect tumors.
Eligibility:
People ages 12 and older with VHL that causes tumors and cysts to grow in the pancreas
Design:
Participants will be screened with their medical records and imaging studies.
Participants will have an initial evaluation:
Participants will have their body examined by different doctors. This will depend on what types of symptoms they have.
Participants will have blood and urine tests
Participants will have images made of their body using one or more machines: They made have a CT or PET/CT scan in which they lie on a table that moves through a big ring. They may have an MRI in which they lie on a table that moves into a big tube. They may have an ultrasound that uses a small stick that produces sound waves to look at the body.
After the first visit, participants will be asked to return to the NIH. Some of the tests performed at the first visit will be repeated. Depending on their disease status, visits will be once a year or every 2 years for life.
详细描述
Background:
- Patients with the von Hippel-Lindau (VHL) familial cancer syndrome demonstrate manifestations in a variety of organs, including the pancreas. Pancreatic manifestations can range from benign cysts and micro cystic adenomas to neuroendocrine tumors of the pancreas which are capable of regional and distant metastases. These neuroendocrine tumors can result in life-threatening complications.
- This protocol is designed to identify VHL patients with pancreatic manifestations and to follow these patients with serial imaging studies, germ line genetic analysis, discovery of serum biomarkers, and novel imaging modalities such as 68-Gallium DOTATATE PET/CT scan.
Objective:
- To comprehensively and longitudinally evaluate the natural history of participants with VHL pancreatic neuroendocrine tumors and cystic lesions, estimating and defining their clinical spectrum.
