Summary Summary


Listen
A VIPoma is a rare cancer caused by a type of pancreatic neuroendocrine tumor, which is tumor that arises from cells that produce hormones - allowing the tumor itself to produce hormones. A VIPoma secretes vasoactive intestinal peptide (VIP), a hormone that stimulates the secretion (and inhibits the absorption) of sodium, chloride, potassium and water within the small intestine.[1] Excessive secretion can increase bowel motility and lead to signs and symptoms such as abdominal pain and cramping, severe watery diarrhea, dehydration, flushing of the face, muscle cramps due to low potassium levels (hypokalemia), and weight loss.[1][2] When a person has a VIPoma and these associated symptoms, it is referred to as VIPoma syndrome, also called WDHA syndrome or Verner-Morrison syndrome.[1] The majority of people with a VIPoma have VIPoma syndrome.[3]

VIPomas are usually diagnosed in middle-aged adults or in young children.[3] Tests used to diagnose a VIPoma may include blood tests (including VIP level), imaging studies such as a CT scan or MRI, and examination of a stool sample.[2] Unfortunately, even though these tumors are slow-growing, the majority of VIPomas are metastatic (have spread to other parts of the body) at the time of diagnosis.[1][3] The underlying cause of VIPomas is not yet known.[2]

Management typically first involves treating dehydration with fluids and correcting the imbalance of hormones and other substances (metabolic abnormalities) in the body. Medications such as octreotide and lanreotide can usually stop the diarrhea and inhibit the secretion of VIP.[1][3] Surgery typically follows in order to remove the tumor. When there is no evidence of metastasis, complete removal of the tumor is the only possible cure.[1] The majority of metastatic cases will not be cured by surgery, but symptoms may be managed and prolonged survival is often possible due to the slow-growing nature of these tumors. Targeted therapy or chemotherapy may also be used for people with progressive, advanced disease. The median survival of people with VIPomas is 96 months, but long-term survival mainly depends on the tumor grade, staging, and whether all or most of the tumor can be removed.[3]

Symptoms Symptoms


Listen

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
