Tumor Biology Impacts Survival in Surgically Managed Primary Hepatic Vascular Malignancies.

Background: Hepatic angiosarcoma (AS) and hepatic epithelioid hemangioendothelioma (HEHE) are rare primary hepatic vascular malignancies (PHVM) that remain poorly understood. To guide management, we sought to identify factors and trends predicting survival after surgical intervention using a national database.

Materials And Methods: In a retrospective analysis of the National Cancer Database patients with a diagnosis of PHVM were identified.
