Hiroshi Tsuji, MD, is Director of the research Program for Carbon Ion therapy and Diagnostic Imaging at National Institute of Radiological Sciences (NIRS), where he has been since 1997. He also currently serves as Head of Clinical Oncology section in the hospital of the same institute. He received a M.D. from Hokkaido University in 1982, and a Ph.D. from Tsukuba University in 1996 for his study on proton radiotherapy of hepatocellular carcinoma. He has had 30 years of experience in clinical research on radiation oncology, including 8 years in Proton therapy and 17 years in carbon ion radiotherapy. The NIRS has more than 8,000 patients experience of C-ion RT, including more than 2,000 prostate cancers. He has actually been in charge of the treatment for these patients and advancing hypofractionation based on the outcomes obtained. His current research centers on standardization and clarification of charged particle therapy, for which he works on clinical trials of hypofractionated C-ion RT for common cancers as well as establishing new treatments for radio-resistant tumors. Particularly, effective usage of newly developed scanning irradiation is a current main concern.
