Answer

High-grade angiosarcomas exhibit extremely aggressive behavior with rapid local growth and early disseminated metastasis. Prognosis depends on the histologic grade, with the disease-free survival rate reported as 95% in grade 1 tumors, 62% in grade 2, and 20% in grade 3. Multicentricity does not affect prognosis.
