Gastrinomas are neuroendocrine tumours (NETs) that start in cells that make the hormone gastrin. Most gastrinomas start in the small bowel (duodenum) and the pancreas.
They are a type of functioning NET of the pancreas.
Gastrinomas are rare NETs that make large amounts of the hormone gastrin.
Possible symptoms of gastrinoma include tummy (abdominal) pain and loose or watery poo (diarrhoea).
You have some tests to diagnose a gastrinoma. This might include blood tests and a test to look at the inside of your food pipe, stomach and small bowel.
The stage and grade of a pancreatic NET helps your doctor decide which treatment you need.
The treatment you have depends on a number of things such as where the gastrinoma is, its size and whether it has spread.
Researchers are looking at improving the diagnosis, treatment and quality of life of people with pancreatic NETs.
You have follow up appointments to check how you are and see if you have any problems or worries.
There are some factors that increase your risk of developing a pancreatic NET. This includes some medical conditions.
Get practical and emotional support to help you cope with a neuroendocrine tumour.
Survival for gastrinomas depends on different factors. So no one can tell you exactly how long you will live.
