Associated Genetic Biomarkers

Overview

NCI Definition: A malignant tumor arising from the endothelial cells of the blood vessels. Microscopically, it is characterized by frequently open vascular anastomosing and branching channels. The malignant cells that line the vascular channels are spindle or epithelioid and often display hyperchromatic nuclei. Angiosarcomas most frequently occur in the skin and breast. Patients with long-standing lymphedema are at increased risk of developing angiosarcoma. [1]

Angiosarcomas most frequently harbor alterations in MYC, TP53, KDR, FLT4, and CRKL [2].

Most Commonly Altered Genes in Angiosarcoma

MYC Amplification, TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, and KDR Mutation are the most common alterations in angiosarcoma [2].
