Interdisciplinary treatment of primary hepatic angiosarcoma: emergency tumor embolization followed by elective...

Among primary hepatic malignancies, sarcomas represent a minority of 2 %. Of those, primary hepatic angiosarcoma is the most common one. In the past its incidence has been related to the exposure of certain chemicals like thorotrast, vinyl-chloride or arsenic. - Patients suffering from this aggressive, highly vascular tumor have a poor prognosis in general. Without treatment most of them die after rapid tumor progression with multifocal dissemination. In case of tumor perforation, fatal abdominal hemorrhage has been observed. - We herein report the successful interdisciplinary treatment of an 81 year-old woman with a perforated primary hepatic angiosarcoma of the left hepatic lobe. Initially, tumor bleeding was stopped by emergency interventional coil embolization. After stabilization of the patient, we performed an elective tumor resection. The patient could eventually be discharged in a good clinical condition. - So far, no standard therapy has established for patients with primary hepatic angiosarcoma. Surgery seems to be the treatment of choice. In addition, preoperative interventional embolization of the tumor supplying vessels reduces the risk of pre- and intraoperative bleeding. The value of adjuvant chemotherapy is not yet clarified. - The outcome of most patients with primary hepatic angiosarcoma remains poor and there is a need for clinical studies.
