Pancreatic islet cell tumors are rare types of hormone-producing tumors that form in tissues of the pancreas. The cells of the pancreas cluster together in small groups, called islets, throughout the pancreas. When a tumor occurs in one of these clusters, it is called an islet cell tumor. It may be benign or cancerous.

What is a pancreatic islet cell tumor?
Pancreatic islet cell tumors are rare types of hormone-producing tumors that form in tissues of the pancreas. The cells of the pancreas cluster together in small groups, called islets, throughout the pancreas. When a tumor occurs in one of these clusters, it is called an islet cell tumor. It may be benign or cancerous.
Is islet cell carcinoma pancreatic cancer?
Pancreatic neuroendocrine tumors (NETs) may be benign (not cancer) or malignant (cancer). When pancreatic NETs are malignant, they are called pancreatic endocrine cancer or islet cell carcinoma. Pancreatic NETs are much less common than pancreatic exocrine tumors and have a better prognosis.
What is the most common islet cell tumor?
Insulinomas are the most frequent functioning pancreatic tumours accounting for 60% of all islet cell tumours [1]. They cause spontaneous hypoglycaemia, relieved by glucose, and are associated with high levels of plasma insulin and C peptide levels.
What are the types of pancreatic islet cell tumors?
Pancreatic islet cell tumor
- Gastrinoma (Zollinger-Ellison syndrome)
- Glucagonoma.
- Insulinoma.
- Somatostatinoma.
- VIPoma (Verner-Morrison syndrome)
Is islet cell carcinoma curable?
These tumors are usually slow-growing tumors and, when localized to the pancreas or regional lymph nodes, can be cured with pancreatic resection.
Is islet cell tumor malignant?
A tumor that forms in islet cells (hormone-making cells) of the pancreas. Islet cell tumors may be benign (not cancer) or malignant (cancer). Islet cells make several different hormones that affect body functions, including controlling the amount of glucose (sugar) in the blood and helping digest food in the stomach.
What is found between islet cells?
The islets of Langerhans contain alpha, beta, and delta cells that produce glucagon, insulin, and somatostatin, respectively. A fourth type of islet cell, the F (or PP) cell, is located at the periphery of the islets and secretes pancreatic polypeptide.

How rare is pancreatic neuroendocrine tumors?
Pancreatic NETs are a less common type of pancreatic cancer. They make up less than 2% of pancreatic cancers, but tend to have a better outlook (prognosis) than the more common type.
Where are islet cells located?
The pancreas contains clusters of cells that produce hormones. These clusters are known as islets. There are several different types of cells in an islet. For example, alpha cells make the hormone glucagon, which raises the glucose (a type of sugar) level in the blood.
