Treatment of Gastroenteropancreatic Neuroendocrine Tumors.

Neuroendocrine tumors (NETs) represent a group of biologically and clinically heterogeneous neoplasms arising from the diffuse neuroendocrine system. Although NETs may develop in almost any organ, they commonly arise in the gastrointestinal tract and pancreas and are referred to as gastroenteropancreatic (GEP)-NETs when they arise from these sites. In recent years, advances in understanding of the biology of NETs have resulted in an expansion in treatment options and improved survival for patients. This review focuses on treatment of GEP-NETS and highlights factors that govern the therapeutic approach.
