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 9,766 (as of February 23, 2016).
  • ・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.

To undergo a medical examination

In order to undergo heavy ion radiotherapy in this hospital, a patient must correspond to one of the following types, and must also meet a number of criteria.
(1) The patient is introduced directly to the hospital by the patient's current attending physician, and meets the hospital's criteria.
(2) The patient and members of the patient's family attend a consultation day at this hospital, with a letter of introduction and materials provided by the patient's hospital, and the patient meets the hospital's criteria after the consultation.

* In addition, patients from overseas are requested to read Flow of the therapy and International medical support.


Because of maintenance of the heavy ion beam irradiation system, the therapy can only be conducted between early April and late July and between early September and the middle of February.

* Due to system maintenance, there are periods around March and August when treatment is suspended.
