title: Early results of ion beam radiation therapy for sacral chordoma. A Northern California Oncology Group Study.
abstract: The authors report on eight patients with sacral chordoma treated with ion beam radiation therapy. Ion beams have favorable physical and biological characteristics when compared to conventional radiation therapy beams of x-rays, gamma rays, or electrons. This treatment technique has been developed to exploit those advantages. With this technique it is possible to deliver a much higher tumor dose than that usually given with conventional beams, and to date no significant normal-tissue morbidity has been noted. Seven of the eight patients currently have local control of their tumor; however, follow-up time is too short to judge the long-term local control rate of this treatment technique.
