| Outline of Final Research Achievements |
In the aging society of developed countries, the morbidity of malignant tumors suddenly destroys the "healthy life expectancy". This means, even in a state where one can live independently in a social life, the end of life will come along with the burden close to despair mentally, physically and economically. However, if gastrointestinal cancer can be detected at early phase, could being fully cured.
In this study, we showed that abnormal methylation is a universal alteration regardless of the type of cancer and possible to screen gastrointestinal cancer in general, including pancreatic cancer, by detecting fecal DNA methylation. For high-risk people with malignancy, continuously detecting fecal DNA methylation could predict in the early stage of onset without any abnormalities in other laboratory findings with extremely minimally invasive, thus lading the foundation for innovative preemptive medicine that enables.

本研究結果により、メチル化異常が癌種に関係なく、普遍的に認められる変化であることが示唆され、適切なバイオマーカー選択により、大腸癌、IPMN、食道癌、胃癌、膵癌、十二指腸癌、胆管癌といった悪性腫瘍群と非担癌群を選別することが可能であることが示された。これら結果から、担癌高リスク者に対し、極めて低侵襲である便中メチル化DNA検出を継続的に行うことにより、検査所見でも異常のない発症前期に膵癌・消化器癌を診断・予測し、薬剤投与等による化学予防 (Chemoprevention) を可能にする革新的な先制医療 (Preemptive Medicine) の構築が可能となると確信している。
