基于靶向免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)的肿瘤免疫治疗在近10年取得了重要进展,程序性死亡因子-1(PD-1)/程序性死亡因子配体-1(PD-L1)抗体治疗则成为肿瘤治疗领域最具潜力的新型疗法。中国肿瘤学者与发达国家学者基本同步开展的肿瘤免疫疗法的临床实践,进一步验证了肿瘤免疫治疗的效果。伴随临床应用数据的积累,ICIs抗肿瘤疗法逐渐暴露出很多不足,如总体治疗应答率偏低、获得性耐药机制复杂以及免疫相关不良反应(irAEs)多有发生等。这些问题都值得引起相关领域专家重视。本文总结了近年来国内外ICIs的临床实践成果,深入分析了当前ICIs疗法面临的挑战,探讨并提出了改善患者获益的策略。 |

Abstract: |
Cancer immunotherapy based on immune checkpoint inhibitors (ICIs) represents the promising advances over the past decade. Demonstrating unprecedented extension of patient survival, antibodies against programmed cell death 1 (PD-1) and its ligand (PD-L1) quickly became the promising novel treatment in anti-cancer therapeutics nowadays. So, immunotherapy of cancer has entered into a new phase. Clinical trials and practices conducted simultaneously by oncologists both in China and the developed countries furtherly proved the clinical efficiency of agents targeting ICIs in treatment of a wide array of cancer types. However, despite the success of ICIs, side effects of antibody targeting ICIs gradually emerged during the widespread use in clinic, including the low overall response rates (ORRs), acquired resistance to these agents, and various immune-related adverse events (irAEs), of which are worthy of attention of the oncologists. This paper summarized the recent progress of ICIs in clinics, discussed the above challenges, and proposed the strategy for increasing benefits of the ICIs therapy. |
