The Evolving Role of Radiation Therapy in Patients with Metastatic Soft Tissue Sarcoma.

Various delivery techniques including stereotactic body radiation therapy (SBRT) or hypofractionated RT can escalate the biologic dose while avoiding normal tissues in order to reduce tumor burden, provide durable local control, palliate symptoms, potentially prevent further seeding of metastatic lesions, and potentially prolong survival. This review summarizes the current state of the literature on the important role of RT for the treatment of metastatic sarcoma organized by the site of metastatic disease. Particularly for patients presenting with oligometastatic or oligoprogressive disease, consolidative RT is an important local therapy strategy to be considered in a multidisciplinary setting.
