Outline of Final Research Achievements

The authors have identified CD24Low/CD44High cells as cancer stem-like cells (CSCs) in esophageal squamous cell carcinoma (ESCC). Furthermore, the authors have reported that FGF-2/FGFR/Erk pathway has critical roles in regulating CSCs in ESCC. In the present study, they have shown that FGFR/Erk inhibitors decrease CSCs in ESCC and restore sensitivity to anticancer drugs and radiation in experiments using organoid culture system, organotypic 3D culture system and xenograft experiments. FGFR/Erk inhibitors could be used as a novel therapy targeting CSCs in ESCC.

Academic Significance and Societal Importance of the Research Achievements

多くの癌において分子標的薬が実用化されている中、進行食道扁平上皮癌(ESCC)においては有効な分子標的薬が未だ無いのが現状である。本研究は進行ESCC症例に対する集学的な新規治療法開発の萌芽となる可能性がある。また、本研究で用いた食道扁平上皮癌3次元培養、オーガノイド、動物モデルは生体内に近い形での癌細胞の培養がin vitroで可能であり、通常培養法では困難な癌研究を飛躍的に向上させてきた。これらの研究手法により今後のESCC研究のさらなる向上が期待される。
