Welcome to the Division of Radiation Oncology, Department of Radiology.
Our division has three major missions: 1)To deliver safe and effective radiation therapy; 2)To develop useful methods and devices; and 3)To guide and train adequate staff to achieve the goals, 1) and 2).
In this super-aging society, radiation therapy is expected to play a larger than ever.Role in cancer treatment as a less-invasive modality. In response to this trend, we offer patient-friendly treatment, with little physical and social burdens, using high-precision radiation therapy.
Now, we are focusing on the following three challenges in clinical research:
-
Breast Cancer
We have applied hypofractionated whole breast irradiation (42.56Gy/16fr/3.2w) in breast-conserving therapy since 2003, achieving excellent outcomes. Compared with the conventional schedule of 50Gy/25fr/5w, this short-course radiation therapy is beneficial in saving time. We will continue this strategy and present long-term results.
-
Prostate Cancer
High dose-rate brachytherapy combined with external beam irradiation for prostate cancer is one of our specialties. More than 1,000 patients have been treated in our institution with remarkable outcomes. Now we have launched a new approach, the so-called “true focal therapy,” in selected patients using this method. Patients can be treated with far less adverse effects and shorter treatment time.

Ablative Palliative Irradiation
In general, palliative therapy does not aim to cure the disease. However, combined with modern effective systemic therapies such as molecular target agents and immune checkpoint inhibitors, local tumor control sometimes has a clinical impact even in palliative settings. High-precision ablative irradiation has been applied to palliative therapy in selected patients and has produced promising results.
