Outline of Final Research Achievements	The relation between obesity and endometrium cancer is unknown. At First, we measured the amount of visceral fat and subcutaneous fat in endometrial cancer patients. The amount of visceral fat was related with prognosis and recurrence rate. Next, FABP4 which is cytokine from visceral fat was treated in endometrial cancer cell lines, cell lines were proliferated. Furthermore, we made the tissue microarray of 354 endometrial cancer patients, and when immunostaining of EMT related protein (Snail, Slug, TWIST, E-cadherin) was performed, the EMT related proteins were increased. The amount of visceral fat of obesity patients would be related with prognosis or recurrence rate in endometrial cancer patients.
Free Research Field	婦人科腫瘍
Academic Significance and Societal Importance of the Research Achievements	我々が肥満および内臓脂肪と子宮体がんの転移・再発に関するメカニズムの一部を解明したことにより、今後子宮体がんの発症予防や治療開発において新たな戦略を構築できる可能性があり、子宮体がん患者の予後改善につながると考える。
