Update on the management of neuroendocrine hepatic metastases.

Neuroendocrine tumors (NETs) are rare and represent a diverse collection of malignancies that occur in many organ systems throughout the body, including the gastrointestinal and respiratory tracts. Unfortunately, the majority of patients with NETs have hepatic metastases at the time of diagnosis. Although some patients may be asymptomatic, others have unusual clinical presentations and variable tumor growth patterns. Although many patients have long indolent courses, without treatment, most patients die within 5 years of diagnosis. This article reviews the care of patients with NETs and hepatic metastases, with emphasis on the increasingly important role of oncologic image-guided interventions.
