Outline of Final Research Achievements

Focusing on chromosomal instability as a biomarker that enables early diagnosis and stratified treatment for pancreatic and biliary tract cancer, qualitative and quantitative analysis of telomere fusion DNA, a surrogate marker that can be analyzed in multiple samples, using a digital PCR platform were performed. We have almost established a protocol applicable for high-throughput analysis. At the beginning of this project, it was difficult to design a optimal primer/probe to obtain reproducible results because the subtelomeric region has many repetitive sequences. In the future, we plan to conduct multi-specimen analysis using the obtained protocol and evaluate the relationship with clinicopathological features.

Academic Significance and Societal Importance of the Research Achievements

最近、胆道癌に対して免疫チェックポイント阻害剤であるデュルバルマブが保険適応となり、胆管癌に対しても免疫チェックポイント阻害剤の有効性を予測するバイオマーカーの開発が急務である。本研究によって得られた染色体不安定性の定性的・定量的評価が免疫チェックポイント阻害剤の治療効果予測となれば、胆道癌における化学療法の層別化に大きな福音となりうる。免疫チェックポイント阻害剤は高額でもあり、治療効果を予測した上で症例を選択すれば、医療経済的な側面でも意義のあるものになりうる。
