Outline of Final Research Achievements

Research into the microbiome is a rapidly advancing field in human cancers. The aim of this study is to clarify the relationship between sarcopenia, nutritional status and microbiome in gastrointestinal cancers. First, we constructed the database of nutritional status and showed that prognostic nutritional index (PNI; nutritional status) was significantly associated with tumor-infiltrating lymphocytes status (tumor immunity). Nutritional status and systemic immune competence may influence patients’ prognosis through the local immune response. Now we have just constructed the database of sarcopenia (using SYNAPSE VINCENT) and microbiome (using 16s sequence) and started to perform the comprehensive analyses.

Academic Significance and Societal Importance of the Research Achievements

腸内細菌叢microbiomeは薬剤などにより後天的に変化させうるものであり、疾患治療のターゲットとしてもきわめて有望である。高齢化が進む日本において“サルコペニア”が深刻な健康問題となってきている。今回の研究で得られるであろう、癌患者におけるmicrobiomeとsarcopnia、栄養状態の関係に関する結果は臨床応用に直結する可能性があり、創薬へ向けた橋渡し研究として極めて意義深いものである。
