The role of radiation therapy in the treatment of osteosarcoma.
Seventy patients received primary surgical or radiotherapeutic treatment for osteosarcoma at the University of California-San Francisco between 1950 and 1974. Twenty-two received surgery alone and 27 received preoperative irradiation followed at varying intervals by surgery. Twenty-one patients received irradiation alone because of tumor location, refusal of recommended surgery, or development of metastatic disease. The results are analyzed and the role of radiation therapy in the primary management of osteosarcoma is discussed. The authors believe that irradiation without chemotherapy offers little in terms of palliation or enhanced survival in patients who are able to undergo radical surgery.
