Background: Hepatic epithelioid haemangioendothelioma (HEH) is a rare vascular neoplasm with unpredictable clinical behaviour.
Aim: To compare overall survival (OS) and disease-free survival (DFS) between liver resection (LR) and orthotopic liver transplantation (OLT) for the treatment of HEH.
Methods: Retrospective review of 30 patients with HEH treated at Mayo Clinic during 1984 and 2007.
Results: Median age was 46 years with a female predominance of 2:1. Treatment included LR (n= 11), OLT (n= 11), chemotherapy (n= 5) and no treatment (n= 3). LR was associated with a 1-, 3- and 5-year OS of 100%, 86% and 86% and a DFS of 78%, 62% and 62%, respectively. OLT was associated with a 1-, 3- and 5-year OS of 91%, 73% and 73% and a DFS 64%, 46% and 46%, respectively. Metastases were present in 37% of patients but did not significantly affect OS. Important predictors of a favourable OS and DFS were largest tumour ≤ 10 cm and multifocal disease with ≤ 10 nodules.
Conclusion: LR and OLT achieve comparable results in the treatment of HEH. LR is appropriate for patients with resectable disease and favourable prognostic factors. OLT is appropriate for patients with unresectable disease and possibly those with unfavourable prognostic factors. Metastases may not be a contraindication to surgical treatment.
