Role of Somatostatin Analogues in the Treatment of Neuroendocrine Tumors.

Neuroendocrine tumors (NETs) are rare epithelial neoplasms with neuroendocrine differentiation originating most commonly in the lungs and gastroenteropancreatic. Treatment includes surgery and other local therapies; treatment of inoperable disease centers around symptom management and control of tumor growth. Somatostatin analogues (SSAs) have been a mainstay of managing hormone-related symptoms. Emerging evidence suggests that they are effective therapies for tumor control also. Peptide receptor radionuclide therapy with radiolabeled SSAs is a new, promising treatment for inoperable or metastatic NETs. This article reviews the role of SSAs in the treatment of NETs.
