Management of liver metastases from non-functional gastroenteropancreatic neuroendocrine tumors: a systematic review.

ABSTRACT: The liver is the most common metastatic organ of neuroendocrine tumors (NETs). NET liver metastases (NETLMs) are categorized into simple liver metastasis (type I), complex liver metastasis (type II) and diffuse liver metastasis (type III), of which diffuse liver metastasis accounts for the highest percentage, up to 60-70%. Radical resection is recommended for all patients with type I and partial type II liver metastases without extrahepatic metastases in G1 and G2 grades, with a 5-year survival rate of 65%-70%. But for patients with G3 or type III liver metastases, treatment is controversial. Ablation and TAE/TACE are commonly used localized treatments. Somatostatin analogue (octreotide and lanreotide) are efficacious in the treatment of better-differentiated NETs and can prolong the progr
