Epidemiology of gastrinoma

Authoring team

  • gastrinomas are the most common islet cell tumours
  • approximately 45% of gastrinomas originate in the pancreas, but as many as 35–40% originate in the duodenum and about 10–15% primarily in peripancreatic lymph nodes
  • gastrinomas can also occur in the stomach, lung, liver and ovary
  • in approximately 25% of patients, the gastrinoma is part of MEN-I (in MEN-I, the gastrin-producing tumour is then often found in the duodenum)
