Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapeutics, triggering studies to understand the molecular and cellular wiring of response and resistance. Our increased understanding of the underlying biology of response to ICI has enabled the investigation of tumor-intrinsic and -extrinsic features that may predict therapeutic outcomes. In parallel, liquid biopsy measurements of circulating tumor DNA (ctDNA) can be used to assess real-time molecular responses and guide clinical decisions during ICI. The combination of these approaches provides a deeper understanding of cancer biology, immunoediting, and evolution during ICI and promise to extend the utility of immunotherapies for patients with cancer.
免疫检查点抑制剂(ICIs)彻底改变了癌症治疗方法,引发了一系列研究,旨在深入了解其作用机制和耐药机制。我们对 ICI 应答相关的分子和细胞机制的理解不断加深,这有助于探索可能预测治疗效果的肿瘤内在和外在特征。与此同时,通过液体活检测量循环肿瘤 DNA(ctDNA)可以实时评估分子应答情况,并指导 ICI 期间的临床决策。这些方法的结合提供了对 ICI 期间癌症生物学、免疫编辑和进化的更深入了解,并有望为癌症患者提供更广泛的免疫治疗选择。
