Curative surgical excision, by open laparotomy or laparoscopy, is the treatment of choice when possible. The open surgical approach is used if the tumor is suspected to be malignant, since en bloc lymphadenectomy is performed for malignant tumors without distant metastases. Intraoperative ultrasound aids the localization of tumor extent and the relationship to other anatomic structures.
The pancreas is an organ located behind your stomach next to the top of the small intestine. It is about six inches long but is less than 2 inches wide and functions as two separate organs. It has two big manufacturing jobs in the body:
It makes digestive juices that help the intestines break down food.
It produces hormones -- including insulin -- that regulate the body's use of sugars and starches.
The pancreas is divided into three sections: the head, the body, and the tail.
Pharmacologic palliation: diazoxide 300 to 500 mg/day.
Somatostatin analogue therapy.
Patients with hepatic-dominant disease and substantial symptoms caused by tumor bulk or hormone-release syndromes may benefit from procedures that reduce hepatic arterial blood flow to metastases (hepatic arterial occlusion with embolization or with chemoembolization).[6,8,9,10,11,12] Such treatment may also be combined with systemic chemotherapy in selected patients.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with insulinoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
