卵巢癌是导致患者病死率最高的妇科恶性肿瘤,临床诊断时晚期患者占比高达70%,传统手术联合铂类化疗后患者复发率高。卵巢癌患者的肿瘤免疫微环境呈现典型的"冷"肿瘤特征,导致免疫检查点抑制剂(ICI)单药治疗对其客观缓解率(ORR)普遍≤10%。近年研究发现,聚腺苷二磷酸-核糖聚合酶(PARP)抑制剂除通过"合成致死"机制靶向癌细胞DNA修复缺陷外,还具有重塑肿瘤免疫微环境的关键作用。临床研究结果显示,PARP抑制剂联合ICI治疗可提升卵巢癌患者的ORR,但是其联合策略迄今尚存在挑战性。笔者拟就卵巢癌的肿瘤免疫微环境、PARP抑制剂对卵巢癌患者的治疗及参与卵巢癌免疫治疗调控作用的最新研究现状进行阐述,旨在为开发PARP抑制剂维持治疗时代的卵巢癌患者免疫治疗方案提供一定思路。

Ovarian cancer ranks as the gynecological malignancy with the highest mortality rate, with approximately 70% of patients presenting at an advanced stage upon clinical diagnosis. Despite conventional treatment involving surgery plus platinum-based chemotherapy, the recurrence rate remains high. The tumor immune microenvironment of ovarian cancer exhibits typical " cold tumor" features, contributing to a suboptimal objective response rate (ORR) of ≤10% with immune checkpoint inhibitor (ICI) monotherapy. In recent years, studies have demonstrated that poly ADP-ribose polymerase (PARP) inhibitors not only target DNA repair defects in cancer cells via the " synthetic lethality" pathway, but also exert a pivotal role in remodeling the tumor immune microenvironment. Clinical evidence indicates that combination therapy with PARP inhibitors and ICI enhances the ORR in ovarian cancer patients; yet, optimizing this combination regimen remains challenging to date. This review summarizes the latest advances in the ovarian cancer tumor immune microenvironment, the therapeutic efficacy and regulatory effects of PARP inhibitors in ovarian cancer immunotherapy, with the goal of providing insights for developing immunotherapy strategies for ovarian cancer patients in the era of PARP inhibitors maintenance therapy.
