VIPoma is a very rare cancer that usually grows from cells in the pancreas called islet cells.
Vasoactive intestinal peptide-producing tumor; VIPoma syndrome; Pancreatic endocrine tumor; Verner-Morrison syndrome; WDHA
VIPoma causes cells in the pancreas to produce a high level of a hormone called vasoactive intestinal peptide (VIP). This hormone increases secretions from the intestines. It also relaxes some of the smooth muscles in the gastrointestinal system.
The exact cause of VIPomas is not known.
VIPomas are often diagnosed in adults, most commonly around age 50. Women are more likely to be affected than men. This cancer is rare. Each year, only about 1 in 10 million people are diagnosed with a VIPoma.
Symptoms of VIPoma may include any of the following:
The first goal of treatment is to correct dehydration. Fluids are often given through a vein (intravenous fluids) to replace fluids lost through diarrhea.
The next goal is to slow the diarrhea. Medicines can help control diarrhea. One such medicine is octreotide. It is a manmade form of a natural hormone that blocks the action of VIP.
The best chance of a cure is surgery to remove the tumor. If the tumor has not spread to other organs, surgery can often cure the condition.

You can ease the stress of illness by joining a cancer support group. Sharing with others who have common experiences and problems can help you not feel alone.
Surgery can usually cure VIPomas. But, in one third to one half of people, the tumor has spread by the time of diagnosis and cannot be cured.
Complications may include:
If you have watery diarrhea for more than 2 to 3 days, contact your provider.
