 note = {Between October 1994 and February 2002, 14 patients with diffuse astrocytoma were enrolled in a phase I/II clinical trial of carbon ion radiotherapy. Carbon ion radiotherapy was administered in 24 fractions over 6 weeks. The carbon ion dose was escalated from 50.4 Gy equivalent (GyE) to 55.2 GyE. Patients were divided into two groups according to their carbon ion doses: a low-dose group in 9 patients and a high-dose group in 5 patients. High-dose group showed significant improvement in PFS and OS rates compared to those in the low-dose group. Toxicities were within acceptable limits. None of the patients developed a Grade 1 or higher acute brain reaction (RTOG), and a Grade 3 or higher late brain reaction (RTOG/ EORTC).},
