福島県/脳神経疾患研究所(南東北グループ):
ホウ素中性子捕捉療法(BNCT)による治療が、「次世代の放射線がん治療法」として、注目を集めています。
民間病院として世界初、南東北BNCT研究センター(高井良尋センター長)で開始しました。
BNCT装置:
京都大学と住友重機械工業が共同開発。
2018年から2019年まで、「首から上の頭頸部(とうけいぶ)にできたがんなどの臨床試験」を実施した。
頭頸部がんの臨床試験を、合計21例実施した。
治験の実績:
90日目の局所効果
- がんが消えた「完全奏功」は5例、
- 30%以上小さくなった「部分奏功」は10例、
- がんが縮小、もしくは消滅した患者の割合を示す「奏功率」は、71・4%。
2年生存率は85%:
患者に生じた有害事象はほとんどが軽かったとのこと。
高井センター長は「有効で安全な治療」と説明している。

The world’s first male patient with pharyngeal cancer was treated with the accelerator-based BNCT (Boron Neutron Capture Therapy)
on May 26, 2020 at Southern TOHOKU BNCT Research Center, Southern TOHOKU Hospital Group.
At 11 a.m., the Founder and Chairman of the Board Dr. Kazuo Watanabe was invited to press the button to switch on the BNCT device.
The radiotherapy
was given by Prof. Yoshihiro Takai, Director of BNCT Research Center and Dr. Katsumi Hirose, Vice Director of BNCT Research Center.
The male patient in his 50s
was successfully treated. He is our center’s first clinical case since the AB-BNCT system and boron drug obtained an approval from Japanese government in March 2020.
BNCT treatment
will be covered by national health insurance in Japan from June 2020.
BNCT, which is one of particle beam therapies, causes reactions between low-energy thermal neutrons and tumor-seeking boron compounds to destroy cancer cells with pinpoint accuracy.
In addition, BNCT is a body-friendly treatment that can minimize negative effects to normal cells and the burdens to patients.
Locally unresectable recurrent or unresectable advanced head and neck cancer with radiation resistant is expected to become indications.
Clinical trials will aim to expand other indications in the near future. For full details visit
