Hepatic Arterial Embolization for Gastroenteropancreatic NET Liver Metastases

#686

Introduction: Selective hepatic arterial embolization (HAE) with polyvinyl alcohol particles has been shown to be equivalent to chemoembolization for patients with hepatic gastroenteropancreatic (GEP) neuroendocrine metastases. There remains debate about its clinical effectiveness and which patients benefit from treatment.

Aim(s): We reviewed the demographics, disease distribution and response to treatment of patients with GEP hepatic pre-dominant metastases undergoing HAE between 2008 and 2012.

Materials and methods: Data was collected on the type of primary, size and number of liver metastases and presence of extra-hepatic disease. Response to treatment was evaluated by biochemical (reduction in urine 5-HIAA), radiological (contrast CT) and clinical (patient-reported symptoms) methods.
