A 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 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...
متن کاملResults of carbon ion radiotherapy for head and neck cancer.
PURPOSE To evaluate the efficacy of carbon ion radiotherapy for head-and-neck cancer in a phase II clinical trial. MATERIALS AND METHODS Between April 1997 and February 2006, 236 patients with locally advanced, histologically proven, and new or recurrent cancer of the head and neck were treated with carbon ions. The treatment dose was 64.0 GyE/16 fractions/4 weeks (or 57.6 GyE/16 fractions/4 ...
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...
