Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor with no standard treatment options. This study reports a case of a patient with a giant intrahepatic tumor who achieved partial response after combined therapy with sirolimus and IFN-a 2b, with no severe adverse events.
Hepatic epithelioid hemangioendothelioma (HEH) is a very rare tumor originated from vascular endothelial cells, with unpredictable malignancy. No standard treatment has been established yet. Although surgical resection and liver transplantation have been reported to be effective treatments with favorable long-term outcomes, the multiple intrahepatic lesions or extrahepatic metastasis makes these procedures unsuitable to most patients. Sirolimus was reported to be an effective drug for epithelioid hemangioendothelioma but only about 10% achieved partial response. Interferon-alpha 2b (IFN-a 2b) has also been used for the treatment of HEH, and the rate of tumor regression was more than 50%. Here, we report a HEH patient with giant intrahepatic tumor (>15cm), who achieved partial response after the combined therapy of sirolimus and IFN-a 2b. The giant intrahepatic lesion (>15 cm) regressed obviously after 8 months treatment and no severe adverse event was reported. The good response and safety of combined therapy with sirolimus and IFN-a 2b provide a promising guidance for future clinical study.
