Overview: the management of metastatic carcinoid tumors.

Chemotherapy, IFN, octreotide, and hepatic artery embolization can be useful for palliation, both of local symptoms and of the carcinoid syndrome, but they have little effect on tumor progression, MIBG therapy is still experimental but may have a future role. OLT should be considered as a palliative procedure in those patients with severe symptoms and no evidence of extrahepatic disease.
