简要总结
To evaluate the efficacy and safety of preoperative olaparib monotherapy and preoperative olaparib plus pembrolizumab combination therapy in patients with untreated stage III, IV high-grade serous or Grade 3 endometrioid ovarian cancer with Homologous Recombination Deficiency (HRD) positivity.
详细描述
To evaluate the efficacy and safety of preoperative olaparib monotherapy and preoperative olaparib plus pembrolizumab combination therapy in patients with untreated stage III, IV high-grade serous or Grade 3 endometrioid ovarian cancer with HRD positivity. The first cohort (Olaparib monotherapy : 10 cases) will be evaluated for the presence or absence of immune cell activation, and the tumor reduction effect will be evaluated in the second cohort (Olaparib plus pembrolizumab combination therapy : 20 cases).
