CARBON ION THERAPY FOR SACRAL CHORDOMAS;;Carbon ion therapy for chodoma : Background Material ;No. of Pts : 95 sacral chordma Gender : 68 males / 27 females Age : 30 - 85(median65) Presentation : 84 primary / 11 post op rec Tumor Diameter : 3～17 cm （Median：9 cm） Tumor Volume : 47～1497 cc （Median：370 cc） (From Jun 1996 to Feb 2007);L5 10 S1 29 S2 29 S3 9 S4~ 7 Post op rec 11 ;Carbon ion therapy - all 16 Fractions over 4week Total dose: 52.8-64GyE : 2, 70.4GyE : 86, 73.6GyE : 7 (3.3-4.6GyE/fr.) Number of port : Two ports : 2 , Three ports : 91, Patch : 2;0.0;Radiation Morbidity;DVH (n=44);Before treatment;Sacral Chordoma (S1) 57yo Female C- Ion RT 70.4GyE/16Fr/4wks;Local Control and Survival Rate in Chordoma;Five years overall survival rate (86%) and Local control rate (88%) in patients with sacral chordoma treated by carbon ion therapy are similar to or even better than those in reported data on patients treated by surgical resection. Four patients treated with a total dose of 73.6 GyE experienced Grade 3/4 skin complications. No other treatment-related surgical interventions including colostomy or urinary diversion were carried out.;Carbon ion therapy is suggested to be an effective and safe treatment for sacral chordomas and could be a promising alternative to surgery. ;;
