Hepatic neuroendocrine metastases: chemo- or bland embolization?

Introduction: Aggressive management of hepatic neuroendocrine (NE) metastases improves symptoms and prolongs survival. Because of the rarity of these tumors, however, the best method for hepatic artery embolization has not been established. We hypothesized that in patients with hepatic NE metastases, hepatic artery chemoembolization (HACE) would result in better symptom improvement and survival compared to bland embolization (HAE).
