Pancreatic neuroendocrine tumor(pNET) is a rare type of pancreatic tumors.The incidence of pNET shows a gradually increasing trend in recent years.The most common organ of distant metastases is the liver.Surgical resection is still the optimal treatment for resectable,well-differentiated liver metastases with no evidence of extrahepatic spread.For unresectable patients,a combination of multiple modalities,such as transarterial chemoembolization,radiofrequency ablation,systemic chemotherapy,and molecular targeted therapy,can prolong the survival time of patients.Liver transplantation should be strictly evaluated on an individual basis.
