Postembolization syndrome is common following transarterial chemoembolization (TACE) and bland embolization (TAE) for hepatocellular carcinoma (HCC) and neuroendocrine (NET) liver metastasis. NCCN antiemesis guidelines include neurokinin-1 antagonists (NK-1) in patients receiving emetogenic chemotherapy, however, these agents are not specified in current SIR guidelines. Surgical RCTs demonstrate decreased narcotic requirements when preoperative COX-2 inhibitors are given. The purpose of this study was to determine if adding an NK-1 antagonist and COX-2 inhibitor reduced post-procedural antiemetic and narcotic use or improved same-day discharge rates following TACE/TAE for HCC and NET liver metastasis.
