Summary Summary


Listen
A pancreatic neuroendocrine tumor, also called an islet cell tumor, is a type of neuroendocrine tumor (NET) that typically arises in the pancreas. However in some cases, a pancreatic NET occurs outside of the pancreas. A NET arises from cells that produce hormones, so the tumor can also produce hormones.[1] It may be benign (not cancerous) or malignant (cancerous). Pancreatic NETs usually grow slowly over many years, but there are fast-growing forms.[1]

Pancreatic NETs are called either functional or nonfunctional. A functional pancreatic NET causes specific symptoms because it makes extra hormones, such as gastrin, insulin, or glucagon.[1][2] Examples of types of functional pancreatic NETs include insulinomas, glucagonomas, gastrinomas, VIPomas, and somatostatinomas.[1] Symptoms depend on the type of hormone being made.[2] A nonfunctional pancreatic NET generally does not cause specific symptoms, but may eventually cause symptoms relating to its location and size as it grows or spreads.[2] Pancreatic NETs can be hard to diagnosis, often not identified until 5 to 10 years after they begin to grow.[1]

Most pancreatic NETs are not inherited and occur sporadically in people with no family history of NETs. However, about 10% are associated with a hereditary cancer or tumor syndrome such as multiple endocrine neoplasia type 1 (MEN1), which has autosomal dominant inheritance.[3]

Treatment options for each person depend on many factors including the type of tumor, its location, whether it has spread to other parts of the body (metastasized), and symptoms present.[1] Treatment options may include surgery to remove all or part of the tumor (and sometimes the lymph nodes), and/or nonsurgical treatments to shrink the tumor, stop it from growing, or alleviate symptoms.[1] The chance of recovery (prognosis) also depends upon these factors and differs from person to person.[2]

Find a Specialist Find a Specialist


Listen

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • The Neuroendocrine Tumor Research Foundation has a Doctor Database for help finding a physician specializing in treating neuroendocrine tumors. They also provide a link to a list of multidisciplinary diagnosis and treatment centers on the same web page.

Research Research


Listen

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

General Clinical Trials & Research

  • The Neuroendocrine Tumor Research Foundation is a non-profit organization to support neuroendocrine tumor (NET) research. Their mission is to accelerate scientific discovery that will help create new and more effective therapies for NETs. Each year they seek and fund basic, translational and clinical research proposals with the potential to further understanding of NETs and accelerate the development of diagnostic and therapeutic interventions for patients.

Organizations Organizations


Listen

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
