Pancreatic neuroendocrine cancer

Pancreatic neuroendocrine cancer can produce excess hormones in some people and tumour-related symptoms in others. It can also cause pancreatic exocrine insufficiency, with pale fatty stools, weight loss and bloating, managed with enzyme replacement therapy.

Overview

Getting your Trinity Audio player ready...

Pancreatic neuroendocrine cancer can affect people in different ways, depending on the type of cancer and whether it produces hormones. Some people experience symptoms related to excess hormone production, while others may have symptoms caused by the tumour itself. Tests and scans can help your healthcare team understand your cancer and plan the most appropriate treatment and follow-up care.

This page provides access to our detailed guide to pancreatic neuroendocrine cancer, covering different types, symptoms, diagnosis, grading, treatment and monitoring. You’ll also find further information about pancreatic exocrine insufficiency (PEI), pancreatic enzyme replacement therapy (PERT) and diabetes, which may be relevant to your care.

Pancreatic exocrine insufficiency (PEI) and pancreatic enzyme replacement therapy (PERT)

People with pancreatic neuroendocrine cancer may develop pancreatic exocrine insufficiency (PEI), either as a result of the cancer itself or following treatment, particularly pancreatic surgery.

  • PEI can lead to malnutrition due to nutrient malabsorption, underlying pancreatic disease effects, and symptom impact on oral intake. Symptoms include steatorrhea (pale, fatty/greasy, loose stools), weight loss, diarrhoea, abdominal pain and bloating.
  • Pancreatic enzyme replacement therapy (PERT) is the primary treatment and significantly improves survival and quality of life in PEI patients.

Diabetes

People with pancreatic neuroendocrine cancer may develop diabetes as a result of the cancer itself or its treatment, particularly if part or all of the pancreas has been removed.

Diabetes is a chronic disease affecting insulin production and usage, crucial for regulating blood glucose. The pancreas produces insulin and glucagon, hormones that maintain blood sugar levels.

In the UK:

  • 4 million people (1 in 15) are diagnosed with diabetes
  • Up to 1 million more are undiagnosed
  • 1 in 5 people with cancer also have diabetes
  • Diabetes can develop before or after a cancer diagnosis, or due to cancer or its treatment
  • Types 1 and 2 are the most common, but Type 3 is often underestimated and undiagnosed, causing challenging swings in blood glucose levels

For the neuroendocrine cancer community, managing diabetes can be particularly complex. Understanding the connection and seeking appropriate care is vital.
