Features of the facility

• ･This facility provides medical services specializing in cancer radiation treatment and diagnosis as a hospital conducting radiotherapy-based research.
• ･This facility is equipped with Japan's first heavy ion beam irradiation system, HIMAC. Since 1994, when research and treatment began, it has conducted heavy ion radiotherapy on the most patients in Japan 11,834 (as of March 2019).
• ･The National Institute of Radiological Sciences (NIRS), which is the parent organization of this facility, has obtained favorable results from many fundamental studies on heavy ion beam medicine, and is in a leading position globally.
• ･While proactively attempting to increase the indications of heavy ion radiotherapy, this facility arranges a "comprehensive protocol" for patients for whom the therapy cannot be indicated.

Diseases targeted, and the estimated period of treatment

The cancers listed below are targeted; the "comprehensive protocol" is arranged to manage diseases other than these cancers as much as possible. The therapy cannot be unconditionally conducted for all diseases regardless of their condition. Depending on the disease, however, there are cases in which treatment in clinical studies is possible.

Diseases treated by advanced medical care

Disease	Estimate of the treatment period
Head and neck cancer: Nose, paranasal cavity, salivary gland, etc.	Four-week treatment
Malignant melanoma (choroid of the eye)	One-week treatment
Carcinoma in the lacrimal gland	Three-week treatment
Lung cancer (non-small cell type): Locally advanced cancer	Three- to four-week treatment Treatment within one week for Stage I
Liver cancer	Treatment within one week
Pancreas cancer	Three-week treatment
Prostate cancer	Three-week treatment
Uterine cancer	Five-week treatment
Rectal cancer (postoperative recurrence), difficult to operate	Four-week treatment
Bone and soft tissue tumor, difficult to operate	Four-week treatment
No other effective treatment despite distant metastasis	Partially favorable
No harmful side effects in past radiotherapy	Partially favorable

Diseases under clinical study:
Esophageal cancer, breast cancer, pancreas cancer (partial), metastatic liver cancer, kidney cancer, etc.
