Clinical trial of carbon ion radiotherapy for gynecological melanoma
Carbon ion radiotherapy (C-ion RT) is an advanced modality for treating malignant melanoma. After we treated our first case of gynecological melanoma using C-ion RT in November 2004, we decided to conduct a clinical trial to evaluate its usefulness for the treatment of gynecological melanoma. The eligibility criteria for enrollment in this study were histologically proven malignant melanoma of ...
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 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 کاملTreatment Planning for the Carbon Ion Radiotherapy
In the three therapy beam times 2007 about 50 patients were planned and treated with our treatment planning software, TRiP98, and its development version, TRiP98BEAM. In the past, the standard method was to optimize the biological target dose distribution for the contributing partial fields singly. Due to the enormous effort for the computation of biological effects, only a simple, but still su...
