Outline of Final Research Achievements

We monitored circulating cell-free tumor DNA (ctDNA) in the patients with pancreatic cancer during treatment using Cancer Personalized Profiling by deep Sequencing (CAPP-Seq). Copy number of Kras mutation from 78.6 copy to 0 copy in a patient with unresectable pancreatic cancer decreased on 3 months after start of chemotherapy, however, increased from 0 copy to 94.4 copy at progression disease on imaging findings. Based on our data, monitoring ctDNA by CAPP-Seq might reflect the effectiveness of the treatments for pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements

本研究により、膵癌患者において、治療前あるいは治療中にcell-free tumor DNA変異解析をモニタリングすることで、gemcibtabine・nab-paclitaxelあるいはFOLFIRINOXによる化学療法の効果予測を行うことができれば、各患者に最適な化学療法を用いた個別化治療を開発でき、また化学療法耐性時には治療方針の変更をすることができ、膵癌患者の生存期間延長に貢献できることが期待される。
