LONG-TERM RESULTS AFTER LIVER-TRANSPLANTATION FOR PRIMARY HEPATIC EPITHELIOID HEMANGIOENDOTHELIOMA

Background: Hepatic epithelioid hemangioendothelioma (PHEHE) is a mult ifocal, low-grade malignant neoplasia characterized by its epithelial- like appearance and vascular endothelial histogenesis. The outcome of 16 patients treated with orthotopic liver transplantation (OLT) is the subject of this report. Methods: A retrospective study of 16 patients with HEHE (7 men, 9 women) with ages ranging from 24 to 58 years (mea n 37 +/- 10.6 years). Follow-up intervals ranged from 1 to 15 years (m edian of 4.5 years). Results: Actual patient survival at 1, 3, and 5 y ears was 100, 87.5, and 71.3%, respectively. Disease-free survival at 1, 3, and 5 years was 81.3, 68.8, and 60.2%, respectively. The 90-day operative mortality was 0. Involvement of the hilar lymph nodes or vas cular invasion did not affect survival. The 5-year survival of HEHE co mpares favorably with that of hepatocellular carcinoma at the same sta ge (stage 4A): 71.3 versus 9.8% (p = 0.001) Conclusions: The long-term survival obtained in this series justifies OLT for these tumors even in the presence of limited extrahepatic disease.
