Outline of Final Research Achievements

In this study, we have established a novel mathematical model to predict the progression and malignant transformation of IDH-mutant glioma. This model would allow us to choose the best treatment option for the patients with those brain tumors, which is still under debates. Moreover, we have developed a urinary liquid genetic diagnosis system that is easy and less invasive. This technology can detect even an early brain tumors, regardless of tumor types, at over 90% of sensitivity and specificity. Our computed mathematical model and urinary-based next-gen diagnosis both have great potential to apply clinically and render patients to survive longer.

Academic Significance and Societal Importance of the Research Achievements

我々が作成したモデルは脳腫瘍の悪性度や大きさを問わず、正確に診断することができた。本研究から尿中のマイクロRNAは今後、脳腫瘍のバイオマーカーとして実用化される可能性が示された。本数理モデルによって、低悪性度IDH変異神経膠腫の各患者さんにとって、悪性化を防ぎ、結果として生存率を向上させる治療が提示できる。また、本解析アプローチは、新たな治療法や他の悪性腫瘍にも応用可能な汎用性の高いものである。
