Abstract

Twelve patients with chondrosarcoma of bone who were treated with radiotherapy at the Seoul National University Hospital between 1979 and 1992 were reviewed. Of the 12 patients, 9 patients were classified with grade I or II chondrosarcoma and 3 patients with mesenchymal or dedifferentiated chondrosarcoma. 3 patients received radiotherapy alone and 9 patients received surgery and postoperative radiotherapy. Tumor doses ranged from 54 Gy to 70 Gy. With a median follow-up of 30 months, three patients died: two with uncontrolled local disease and one with distant metastasis. The remaining 9 patients(75%, 9/12) showed the long-term survival after radiotherapy, which suggests that radiotherapy may be contributed to improve the local control or cure rate in the management of chondrasarcoma of the bone.
