Radiation therapy has become one of the main treatments for malignant tumors. In our department, radiation therapy has been applied to various diseases mainly on malignant tumors. In addition, benign diseases, such as keloid and schwannoma, have been also treated.
In general, radiation therapy has been divided into external beam radiotherapy using X-rays and brachytherapy using a small radiation isotope. In our department, not only modern 3-dimensional radiation therapy but also highly precise radiation therapy, such as stereotactic radiation therapy (pinpoint irradiation) using CyberKnife or intensity modulated radiation therapy (IMRT). Also, brachytherapy has been applied to the patients with prostate cancer, gynecological cancer and tongue cancer.
Recently, particle therapy (carbon ion therapy and proton therapy) have been recognized as a promising strategy for malignant tumors. In our department, consultation for particle therapy opens on the afternoon of every Thursday.


Treatments of radiation therapy have been decided based on the consensus of our expert staffs including radiation oncologists and medical physicists, thereby suitable treatment can be achieved with irradiating to the tumor precisely and also effectively reducing irradiation to normal tissues. IMRT has been applied to patients with brain tumor, head and neck cancer, uterine cervical cancer and prostate cancer. Stereotactic radiation therapy using CyberKnife has been applied to patients with metastatic brain tumor, head and neck cancer, primary and metastatic lung cancer, primary and metastatic liver tumors and prostate cancers. CyberKnife has a system confirming a position of a patient and if there is a movement during treatment, this machine promptly run after the patient automatically. Because it is not necessary to fix a metal frame to the skull with a screw, less invasive treatments can be achieved, especially for patients with metastatic brain tumors. Reservation for CyberKnife treatment will be available at any days of outpatient clinic.
Concerning brachytherapy, treatment with 125 iodine seeds for prostate cancer (mainly low risk case) and treatments with high-dose-rate brachytherapy for gynecological cancer, prostate cancer and tongue cancer are available.

Considerations in referring your patients to Radiotherapy

Please introduce the treatment requests for Cyberknife and the consultation of particle therapy directly to our departments with an introduction letter with data including blood tests and the images of CT MRI and/or PET-CT. Concerning other diseases, please introduce at first to the main department of each disease.
