Outline of Final Research Achievements

In this study, we will elucidate the onset mechanism of radiation cognitive impairment using Advanced MRI in long-term survivors of childhood cancer and verify it in post-irradiation cognitive impairment mice. In childhood cancer long-term survivors, microstructural changes and brain activity changes were quantified using Advanced MR including T2 star. In addition, the same subject was subjected to an adult function test and a function test, which are cognitive function tests, and the test results were quantified and analyzed. At the same time, a QOL evaluation was performed on the same subject using a questionnaire. In addition to the above cognitive function test and QOL evaluation, data including basic patient information was organized.

Academic Significance and Societal Importance of the Research Achievements

小児がん長期生存者の約50%に放射線認知障害が生じる。放射線認知障害のリスク診断、認知障害を回避した新しいがん治療法(発症予防)、認知障害の遺伝子治療の開発を目指すには、その発症機構の解明が急務である。一方長期生存者からの病理組織採取は難しい。現在Advanced MRIにより、脳微細構造変化に相当するパラメーターや(微小血管障害、脱髄、神経細胞密度、血管密度)行動の際の脳活動が非侵襲的評価できるようになっている。
本研究の目的は、小児がん長期生存者を対象に、Advanced MRIを用いて放射線認知障害の発症機構を解明することである。
