Outline of Final Research Achievements

We examined the concentration of inflammation-related mediators in glioblastoma(GBM) patients' cerebrospinal fluid and examined their relationship with tumor-associated macrophages. Cerebrospinal fluid of GBM patients was classified into two major clusters. sCD163 concentration correlated with the amount of CD163-positive tumor-associated macrophages infiltrating into the tumor, and sTNF-R1, sTNF-R2, TNFSF13, TNSFSF13B, sIL-6Ra, Pentraxin, and MMP-2 had a strong positive correlation, however,IL-35, IL-32, IL-34, IFN-b, IL-22 had a strong negative correlation. In addition, patients with low IFN-b, IL-2, IL-22 IL-34, IL-35 had a significantly worse prognosis.

Academic Significance and Societal Importance of the Research Achievements

膠芽腫(GBM)は極めて悪性で、手術および放射線化学療法などの集学的治療が施行されるも、5年生存率は10%未満である。従って、新たな治療法が切望される。膠芽腫組織内には様々な免疫細胞(リンパ球やマクロファージ)が存在し、免疫微小環境を構築しているが、詳細は明らかでない。本研究では髄液中の炎症関連メディエーターの濃度およびその相関性から、腫瘍内の免疫環境を解析した。sCD163濃度およびCD163陽性マクロファージの浸潤量は、様々なメデイエーターと関連性があり、膠芽腫組織内の免疫微小環境に大きく影響することが明らかとなった。sCD163の測定は腫瘍内免疫微小環境の把握には有用である。
