Outline of Final Research Achievements

The prognostic significance of CLDN9 expression in endometrial cancer was evaluated by immunohistochemical staining and semi-quantification using formalin fixed paraffin embedded specimens. The 5-year disease specific survival rate of high CLDN9 expression group was significantly lower than of low CLDN9 expression group. In addition, multivariate analysis revealed that high CLDN9 expression was an independent prognostic factor.

Academic Significance and Societal Importance of the Research Achievements

CLDN9は子宮体がんの予後不良例を抽出する予後予測マーカーとして有用である。さらにCLDN6と組み合わせることで、より広く予後不良症例を抽出することができる。今後、分子生物学的なメカニズムを行い、CLDN9を標的とした個別化医療を行うことができる可能性がある。さらに、CLDN6との抗体カクテルによる層別化や治療標的に貢献しうる。
