| Outline of Final Research Achievements |
In this study, we used mouse ovarian and uterine cancer models to demonstrate that antitumor effects of conventional chemotherapies cancer drugs and immune checkpoint inhibition via dynamic change of not only tumor cells but also several immune cells and immune-related factors. In addition, we also identified several factors that induce or inhibit certain types of immune cells fractionation, which were not found in our previous studies, and confirmed that these factors enhance the anti-tumor effect when used in combination with conventional chemotherapy and immune checkpoint inhibitors in a mouse tumor-bearing models.

| Academic Significance and Societal Importance of the Research Achievements |
婦人科腫瘍は、初回治療には反応しやすいが、再発症例や1次治療が無効となると有効な2次治療がないため予後不良であったが、従来の治療に上乗せ効果を示す可能性が示唆された。そのため、本研究の成果によって、婦人科腫瘍患者の予後改善に大きく寄与するとともに、がん腫横断的に幅広く有効性を示す可能性が高いため、様々ながん種における研究・治療全般への波及効果が期待される。
