Outline of Final Research Achievements

Infiltrative tumor growth into adjacent soft tissues is a major cause of the frequent recurrence of sarcoma, and no useful biomarkers are available for tumor monitoring. The aim of the present study was to identify fibroblasts.
Serum miRNA expression may represent a novel diagnostic target for monitoring of highly aggressive sarcoma. Furthermore, exosomal miRNA could act as a transfer messenger to adjacent cells and mediate the infiltrative nature of sarcoma, revealing a crosstalk between tumor cells and normal cells in the tumor microenvironment.

Academic Significance and Societal Importance of the Research Achievements

肉腫には明らかな特異的バイオマーカーもなく、化学療法などでの根治を期待できる治療薬は無い。本研究では、臨床において肉腫のバイオマーカーの発見ができることにより早期発見、早期治療に繋げることが可能となる。さらには、根本的な治療薬とまではいかないにしろ、術前or術後の治療薬として浸潤や転移を抑制することで根治できる可能性が高くなると考えられる。
