Outline of Final Research Achievements

Previously, ct-DNA derived from gliomas in cerebrospinal fluid has been difficult to accurately analyze. We have developed an analysis method using a digital PCR system and succeeded in detecting each mutation with high sensitivity for driver mutations: IDH, TERT, and H3 (J neurooncol. 2021;152(1):47-54.)
Furthermore, in order to respond to the latest molecular diagnosis corresponding to WHO 2021, we developed liquid biopsy using the MLPA method (Neurooncol Adv. 2023;5:1-11. vdac178)

Academic Significance and Societal Importance of the Research Achievements

実際の臨床で採取した髄液を用いて、術前診断に繋げる試みを導入しており、一部の患者では臨床に役立つ知見を得られるようになってきている。具体的には髄液中の微量核酸の遺伝子解析の結果により、diffuse midline gliomaの診断が得られて、手術を回避して放射線化学療法を行った症例を経験した。
