title: Remission of symptoms of chemotherapy-refractory metastatic insulinoma using octreotide.
abstract: The symptoms resulting from the hyperinsulinemia of severe refractory metastatic insulinoma were palliated using self-administered divided doses of a long-acting minisomatostatin analog, octreotide. The substance was well tolerated and the attributable side effects were minimal (primarily gastrointestinal complaints). There were significant improvements in peripheral edema, ascites, and serum electrolytes throughout therapy. Serum insulin and glucagon levels were largely unchanged. Computed tomography scans performed during therapy showed stabilization of pancreatic and hepatic disease. Severe, recurrent hypoglycemic episodes due to hyperinsulinemia were reduced both in number and severity for almost a three-month period. This allowed the elimination or reduction of other chronic, supportive medications and improved quality of life.
