Current Management of Angiosarcoma: Recent Advances and Lessons From the Past

Opinion statement Despite their rarity, angiosarcomas are one of the most aggressive soft tissue sarcomas. Management can often be challenging due to their location and infiltrative nature. A multidisciplinary treatment approach is always warranted, but the recurrence remains high even for localized tumors despite multimodality treatment. In the metastatic setting, cytotoxic chemotherapies, targeted therapies, and, more recently, immunotherapy are used. The sequence of systemic therapies remains currently a topic of active investigation. Over the last couple of years, there have been significant advances in understanding angiosarcoma biology, most notably via patient-driven initiatives like the Angiosarcoma Project. The knowledge derived from such translational work has led to identifying potential biomarkers of response to treatments and exploring new therapeutic avenues. More clinical trials are underway to expand treatment options and improve patient outcomes.
