Outline of Final Research Achievements

Endometrial cancer is known to have a hormone-dependent growth. Abiraterone, a hormone synthase CYP17 inhibitor, is used as a hormone therapy drug for prostate cancer patients. In this study, we clarified the significance of CYP17 in endometrial cancer and found that abiraterone may also be effective in endometrial cancer. CYP17 are expected as new hormone therapeutic target for endometrial cancer.

Academic Significance and Societal Importance of the Research Achievements

子宮内膜癌の術後補助療法として副作用の少ないホルモン療法が望まれますが、代表的な黄体ホルモン療法を含めてその効果は明確ではありません。しかし様々な研究から子宮内膜癌はホルモン依存性に増殖することは明らかであるため、さらなるホルモン療法に関する研究の発展が望まれてきました。本研究では、CYP17の子宮内膜癌での意義を初めて明らかにすることができ(学術的意義)、さらに既存の前立腺癌ホルモン療法剤が子宮内膜癌に対しても有効である可能性を示すことができました(社会的意義)。
