Effect of extrahepatic disease on transarterial chemoembolization for metastatic carcinoid.

283 Background: Transarterial chemoembolization (TACE) is the locoregional therapy of choice for the management of patients with inoperable carcinoid liver metastases. Often, metastatic disease is not limited to the liver. The impact of extra-hepatic metastases on response and outcomes following TACE has not been described. Objective: We hypothesized that patients who have extra-hepatic disease would have similar tumor response and symptom control following TACE. Methods: We reviewed 198 patients that underwent TACE for inoperable carcinoid liver metastases. Two groups were identified, those with (N= 129) and without (N= 69) evidence of extra-hepatic disease at the time of TACE. Demographics, clinicopathologic characteristics, response to TACE, complications, and survival were compared. Results: The two groups were similar in demographics and histopathologic characteristics. Complications following TACE were similar. There was no difference between the groups with and without evidence of extrahepatic dise...
