Carbon ion radiotherapy: clinical experiences at National Institute of Radiological Science (NIRS).
In June 1994, the world's first clinical center offering carbon ion radiotherapy opened at the National Institute of Radiological Science (NIRS), Japan. Among several types of ion species, carbon ions were chosen for cancer therapy because they were judged to have the most optimal properties in terms of superior physical and biological characteristics. As of March 2010, 5,196 patients have been...
متن کاملA Review of Update Clinical Results of Carbon Ion Radiotherapy
Among various types of ion species, carbon ions are considered to have the most balanced, optimal properties in terms of possessing physically and biologically effective dose localization in the body. This is due to the fact that when compared with photon beams, carbon ion beams offer improved dose distribution, leading to the concentration of the sufficient dose within a target volume while mi...
متن کاملClinical advantages of carbon-ion radiotherapy
Carbon-ion radiotherapy (C-ion RT) possesses physical and biological advantages. It was started at NIRS in 1994 using the Heavy Ion Medical Accelerator in Chiba (HIMAC); since then more than 50 protocol studies have been conducted on almost 4000 patients with a variety of tumors. Clinical experiences have demonstrated that C-ion RT is effective in such regions as the head and neck, skull base, ...
متن کاملCarbon-ion radiotherapy—basic and clinical studies
Radiotherapy using charged and/or high-LET particles has a long history, starting with proton beams. In vitro data clarify that RBE (Relative Biological Effectiveness) increases with LET up to approximately 150 keV/μm for carbon-12 and neon-20 ions. In vivo studies show that tumor control probabilities after single doses of gamma rays shift to higher doses when tumors were irradiated with 5-fra...
متن کاملInitial Results of Hypofractionated Carbon Ion Radiotherapy for Cholangiocarcinoma.
AIM To report initial results of hypofractionated carbon ion radiotherapy (C-ion RT) for cholangiocarcinoma. PATIENTS AND METHODS Data regarding seven patients with cholangiocarcinoma treated by C-ion RT were analyzed. Prescribed doses were 52.8 Gy [relative biological effectiveness (RBE)] or 60.0 Gy (RBE) in four fractions for intrahepatic cases and 12 fractions for hilar hepatic/close to ga...
