Chemoembolization for neuroendocrine liver metastasis.

The liver is the most common site for neuroendocrine tumor metastasis. The characteristic feature of these tumors is related to the secretion of biologically active compounds in large amounts. Systemic chemotherapy has limited success in treating patients with neuroendocrine liver metastasis. Surgical management remains the only potentially curative option for these patients. According to the high incidence of recurrence after surgery, the role of intra-arterial therapy (IATs) in neuroendocrine tumor metastasis has been evolved. This review evaluates the potential role of IATs in the light of current literature.
