Outline of Research at the Start

膵癌患者血液のリキッドバイオプシーによる腫瘍特異的ゲノム異常が、術後再発転移の超早期バイオマーカーと成り得るか?との問いを検証する。併せて、術後再発高危険患者の臨床的再発確定前の治療介入を行う事が、患者個々のアウトカムを個別化治療として改善するかを検討する。さらに、得られた治療標的となりうる (actionable)変異について、膵癌細胞と正常膵管上皮細胞培養系を用いた機能解析から、膵癌術後再発・転移過程へ如何に関与するかについての機序を探索する。

Outline of Final Research Achievements

We conducted prospective observational cohort study with NGS based-plasma and tumor genome profiling in pancreatic cancer patients, revealing the following: 1) Somatic mutations in tumor tissues were present in 85% of cases, and the recurrence-free survival (RFS) of preoperative circulating tumor DNA (ctDNA)-positive cases matching the tumor was significantly shortened (13.4M vs. not reached, p=0.001). 2) Postoperatively, the RFS of ctDNA-positive cases significantly decreased with longitudinal monitoring (13.4M vs. NR, p=0.001). 3) Preoperative ctDNA positivity emerged as an independent risk factor for latent occult metastasis and early (竕ヲ6M) postoperative recurrence (OR 5.0; 95% CI 2.1-11.9; p < 0.001).
Clinical implication of ctDNA in managing pancreatic cancer has the potential to predict poor prognosis at diagnosis and before treatment and may serve as a biomarker for postoperative recurrence.

Academic Significance and Societal Importance of the Research Achievements

膵癌は死亡率が高く予後不良であることから、根治術後の再発リスク評価に有用なバイオマーカーの開発が急務となっている。リキッドバイオプシー、とくに患者血漿のctDNA解析は、早期発見に有望かつ効果的として期待されている。一方、膵癌患者におけるctDNAの検出率は低く、バイオマーカーとしては限界があった。本研究では、腫瘍組織情報を加味することでctDNA検出率が向上し、リキッドバイオプシーという生体を包括するゲノムプロファイリングが、切除後再発のモニタリングマーカーとして活用可能なこと、潜在的な遠隔転移予知、術前治療に伴う病性制御を評価するためのバイオマーカーに応用可能なことを示した。
