OBJECTIVE: To examine treatment of hepatic epithelioid hemangioendothelioma (EHE), a rare vascular tumor with a variable course. Treatment modalities at our institution include liver resection, transplantation, and catheter-based therapies. DESIGN, PATIENTS, AND MAIN OUTCOME MEASURES: Retrospective review of 25 patients treated for hepatic EHE (1976-2007). We examined treatment modality, overall survival, complications, and clinicopathologic characteristics. RESULTS: Of the 25 patients treated for hepatic EHE, 17 underwent liver transplantation (LT); 4, transcatheter arterial chemoembolization (TACE); 2, resection; and 2, TACE followed by LT. Twelve patients (48%) were male. The median age at diagnosis was 38 years (range, 9 months to 72 years). Mean overall survival was 167 (95% confidence interval [CI], 123-212) months, with 172 (124-220) months in the LT group and 83 (54-112) months in the TACE group. The 2 patients in the resection group remain alive after 19 and 71 months. The 2 patients treated with TACE followed by LT died after 13 and 113 months. Extrahepatic disease was identified as a predictor of outcome. Patients with extrahepatic disease treated with TACE fared better than those treated with surgical approaches (mean survival, 83.0 [95% CI, 54.2-111.8] vs 38.8 [23.7-53.8] months; P = .12). CONCLUSIONS: Hepatic EHE is a rare tumor that can be treated with surgical or nonsurgical approaches. In our experience, LT is used for patients with advanced local disease, whereas TACE is the primary modality when extrahepatic disease or comorbid conditions prohibiting LT are present. To our knowledge, this is the largest single-institution experience describing the various therapeutic modalities in the treatment of hepatic EHE.
