Salvage Hypofractionated Radiotherapy in a Progressive Radiation-Induced Angiosarcoma: A Case Report.

We report a case of a long-term local control and survival achieved in a patient affected by radiation-induced angiosarcoma (RIA). A 57-year-old woman had a history of breast-conserving surgery and radiation therapy for primary breast cancer. Eight years after the mastectomy, multiple nodal progression was diagnosed as RIA and subsequentially treated by salvage lymph node dissection followed by adjuvant intensified radiotherapy to control the residual disease. Two and a half years later, the patient is alive and cancer-free. This experience shows that radiotherapy may have the potential to be a feasible and effective treatment to control RIA progression, and it may also play a role in the management of RIA as adjuvant.
