Heavy ions have superior depth-dose distribution and greater cell-killing ability. In june 1994, clinical research for the treatment of cancer was begun using carbon ions generated by HIMAC. Until August 2002, a total of 1,297 patients were enrolled in clinical trials. Most of the patients had locally advanced and/or medically inoperable tumors.Tumors radio-resistant and/or located near critical organs were also included. The clinical trials revealed that carbon ion radiotherapy ptovided definite local control and offered a survival advantege without unacceptable morbidity in a variety of tumors that were hard tu cure by other modalities.}, pages = {1142--1145}, publisher = {American Institute of Physics}, title = {Benefit of Carbon Ion Radiotherapy in the Treatment of Radio-resistant Tumors}, year = {2002} }
