10Radiation TherapyRevolutionary advances in radiation therapyIn recent years, remarkable progress has been made in the technology and techniques used in radiation therapy. The Cancer Institute Hospital offers highly accurate radiotherapy, such as stereotactic body radiation therapy (SBRT), intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), and image-guided radiation therapy (IGRT). SBRT is highly effective for treating early-stage non-small cell lung cancer by precisely delivering high doses of radiation. IMRT is a radiation technique that conforms the radiation eld to the exact shape of the tumor, and is used to treat prostate, head and neck, and gynecological cancers. The radiation technologies at the Hospital make it possible to deliver higher doses of radiation to target lesions without damaging adjacent normal tissue. Radiation oncology team treats tumors throughintegrated effortsIn the Hospital, specialists offer cancer care as a dedicated radiation therapy team. Radiation oncologists accurately determine the main lesion and the extension of the cancer and work closely with medical physicists and radiotherapy technologists to create the treatment plan. Radiotherapy technologists operate the radiotherapy units, quality control specialists check on safety management, certificated nurses specialize in daily patient care, and medical clerks work on schedule management. In addition, the radiation therapy team provides educational training to other institutional medical staff, thereby contributing to improvements in radiation therapy in Japan.Intensive safety checking system in radiation therapy To deliver safer and more-accurate treatment, the Radiation Oncology Department has developed a Radiation Oncology Information System in collaboration with system engineers. Linking patient information directly to radiotherapy devices, this system prevents excessive or unnecessary irradiation of patients. By cross-checking updated patient data, which is entered by various specialists, with regimen details stored in the radiotherapy units, the system immediately stops irradiation when there is any inconsistency between patient information and regimen details. Radiation oncology specialists work as a team to provide highly accurate, safe, and curative radiation therapy with minimal radiation-related toxicities. We conduct personalized radiation therapy in treating 1,200 cases a year to achieve each patient’s cure goal.‘’Masahiko Oguchi, M.D., Ph.D.Department Director of Radiation Oncology
