  1. Gastrinoma

    The approach to treatment often depends on the results of preoperative localization studies and findings at exploratory laparotomy. At exploration,85% of these tumors are found in the gastrinoma triangle with 40% on the surface of the pancreas and 40% outside of the pancreas. Only 15% are found within the substance of the pancreas. Percutaneous transhepatic venous sampling may occasionally ...

  2. General Information About Pancreatic Neuroendocrine Tumors (Islet Cell Tumors)

    Tumors of the endocrine pancreas are a collection of tumor cell types collectively referred to as pancreatic neuroendocrine tumors (NETs). These tumors originate in islet cells. Although they may be similar or identical in histologic appearance to carcinoid tumors of the gastrointestinal tract, differences in their underlying biology and likely differences in response to therapeutic agents suggest that they should be treated and investigated as a distinct entity.[1] They are uncommon cancers with about 1,000 new cases per year in the United States.[2] They account for 3% to 5% of pancreatic malignancies and overall have a better prognosis than the more common pancreatic exocrine tumors.[2,3] Five-year survival is about 55% when the tumors are localized and resected but only about 15% when the tumors are not resectable.[3] Overall 5-year survival rate is about 42%.[2]Figure 1.

  8. General Information About Pancreatic Neuroendocrine Tumors (Islet Cell Tumors)

    Pancreatic neuroendocrine tumors form in hormone-making cells (islet cells) of the pancreas.The pancreas is a gland about 6 inches long that is shaped like a thin pear lying on its side. The wider end of the pancreas is called the head, the middle section is called the body, and the narrow end is called the tail. The pancreas lies behind the stomach and in front of the spine. Anatomy of the pancreas. The pancreas has three areas: head, body, and tail. It is found in the abdomen near the stomach, intestines, and other organs. There are two kinds of cells in the pancreas:Endocrine pancreas cells make several kinds of hormones (chemicals that control the actions of certain cells or organs in the body), such as insulin to control blood sugar. They cluster together in many small groups (islets) throughout the pancreas. Endocrine pancreas cells are also called islet cells or islets of Langerhans. Exocrine pancreas cells make enzymes that are released into the small intestine to help the
