| Outline of Final Research Achievements |
In order to identify genetic aberrations that may be therapeutic targets in clear cell sarcoma, we collected tumor specimens from sarcoma centers in Japan and performed genomic analysis using next-generation sequencers.
In cases where a specific fusion gene was identified in clear cell sarcoma, the prognosis was worse in the group with a higher number of gene mutations, and some cases harbored a recurrent mutation. Furthermore, the expression of MiTFs and c-METs downstream of the fusion gene was increased, which was expected to promote tumor cell growth of clear cell sarcomas.

| Academic Significance and Societal Importance of the Research Achievements |
その希少性ゆえに新規薬剤の開発が進まない希少がんにおいて、貴重な組織検体を施設の垣根を超えて持ち寄り解析を行うことは大変重要である。我が国の誇る遺伝子解析技術を利用した遺伝子解析により、難治性疾患である明細胞肉腫の治療標的が同定されることで、有効な薬剤がない本疾患への新たな治療戦略が構築されることが期待できる。
