Department of Radiation Oncology

Introduction of departments

Radiation Oncology Department at Hiroshima University Hospital is one of the largest radiation therapy facilities in west Japan.  We have 7 certificated radiation oncologists specialized in lung, esophagus, breast, head & neck, prostate, brain and other cancer treatments. Our primary goal is to provide high quality expert service to the cancer patients. Our department has started intensity-modulated radiation therapy (IMRT) in 2008 and introduced the newest  IMRT technique “volumetric-modulated arc therapy (VMAT)” in 2010. We have also developed the image-guided radiation therapies (IGRT) to improve the clinical outcomes with minimizing the adverse effects. We also actively provide stereotactic body radiotherapy (SBRT) which permits millimeters order precision for lung and liver cancers.

We have started the new treatments including VMAT for thoracic esophageal cancers, image-guided brachytherapy (IGBT) for uterine cervical cancers and high-dose-rate brachytherapy for oral cancers.
