Outline of Final Research Achievements

Objective: We aimed to identify the genetic alterations associate with resistance to progestin therapy for fertility-sparing treatment of endometrial cancer. Methods: Patients with AEH or G1 without myometrial invasion or extrauterine lesions who underwent progestin therapy (oral MPA administration 400-600 mg/day) were enrolled. We conducted comprehensive integrated analyses of genomic data with clinicopathological features. Results: Complete response (CR) rates and stable or progressive disease (SDPD) in the initial treatment groups were 68% and 32%, respectively. In the initial treatment CR group, 52% patients recurred within 2-years. In the repeated treatment group, CR rates and SDPD rate were 16% and 84% respectively. In the time-course sample analyses, ESR1-activating mutations were indicated in progestin therapy resistance case.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果、黄体ホルモン療法の対象になる類内膜癌はその全てがエストロゲン依存性の癌ではなく、抗エストロゲン効果を持つ黄体ホルモン療法のみでは限界があることが分子生物学的に示された。又、黄体ホルモン療法の時系列検体を用いた解析では、PTEN、CTNNB1、CHD4、ARID5Bの変異、又は、エストロゲン受容体ESR1の活性化変異の獲得が治療抵抗性となった時点で出現していた。以上より、妊孕性温存療法における治療層別化の必要性が示された。
