Novel Treatment Options for Neuroendocrine Tumors.

Neuroendocrine tumors (NETs) are not as rare as once thought, with a current prevalence that is estimated to be higher than that of many other gastrointestinal tumors. Multiple treatment options are available for these tumors, which are categorized according to their histology and site of origin. For patients with metastatic disease, somatostatin analogues are often the initial treatment, with other options considered when these drugs fail.
