Outline of Final Research Achievements

Mobilization of CTCs after various types of therapy has been reported, but systematic study of CTCs after chemotherapy remained quite limited. CTC numbers after single-dose and repetitive-dose chemotherapy were examined in FORFIRINOX or GnP using pancreatic cancer xenograft models and CTC was detected by the immunocytology-based microfluidic platform. We confirmed a transient increase in CTCs 1-2 weeks after single-dose and repetitive-dose of chemotherapy. Histological examination of the primary tumors revealed that the peak period of CTC at 1-2 weeks after chemotherapy corresponded to the maximal destructive phase consisting of cell cycle arrest and apoptosis of tumor cells.

Academic Significance and Societal Importance of the Research Achievements

膵癌患者に対する化学療法レジメンの普及により5年生存率が約10年で10%(2020年1月)に到達したが未だ、化学療法施行時における、①重篤な副作用出現、②薬剤耐性による無奏功、③転移の発見、によって化学療法レジメンの中断・中止・切替により予後不良へ転向を阻止する対策が望まれている。本課題では、リキッドバイオプシーでのCTCを活用した膵癌化学療法の有効性・安全性を担保し得る高精度治療マネジメントプラットフォームの構築から膵癌患者の予後改善を目指して、長期治療施行時のCTC動態の検討に基づいて行うことで精度の高い治療マネジメントが期待される。
