Outline of Final Research Achievements

By focusing on bacterial-translocation, phenomenon in which human intestinal bacteria migrate into circulating blood in human body via intestinal wall, using highly-sensitive detection assay for viable bacteria, I investigated whether bacteria in the blood would be associated with the occurrence of adverse effects of cancer chemotherapy. The results revealed that patients with cancer were always prone to bacterial-translocations regardless of the administration of anticancer drugs, suggesting that bacterial-translocation would be the cause of febrile neutropenia, infection, and diarrhea/enteritis, which are caused by cancer chemotherapy.

Academic Significance and Societal Importance of the Research Achievements

一般に,抗がん薬の副作用は骨髄細胞をはじめとする正常細胞の傷害によって引き起こされる.本研究では,抗がん薬の投与による腸管壁細胞の傷害とは直接関係なく,がん患者ではバクテリアルトランスロケーションが常に発生しやすい状態であること,それが副作用の発症に関わっている可能性を見出した.抗がん薬の副作用の新しい治療法の開発につながる可能性がある.
