免疫检查点阻断(ICB)疗法彻底改变了癌症治疗。然而,只有一小部分患者对 ICB 治疗有反应。准确预测患者可能对 ICB 产生反应将最大限度地提高 ICB 治疗的疗效。肿瘤微环境(TME)决定肿瘤进展和治疗结果。在这里,我们根据血管生成和 T 细胞活性分析 11,069 名癌症患者的转录组,对 TME 进行分类。我们发现 30 种非血液癌症中存在三种不同的血管免疫 TME 亚型。 TME 中的血管生成和抗肿瘤免疫之间存在明显的负相关关系。值得注意的是,在四种癌症类型中,具有低血管生成和强抗肿瘤免疫力的 TME 患者对 ICB 治疗的反应最为显着。肾细胞癌临床试验的重新评估提供了令人信服的证据,表明基线血管免疫状态可以有力地预测 ICB 反应。这项研究为未来 ICB 治疗策略纳入基线血管免疫评分提供了依据。血管生成和 T 细胞免疫在肿瘤微环境中呈负相关 血管生成和 T 细胞活性用于对肿瘤微环境进行分层 血管免疫亚型是抗 PD1/L1 治疗后生存的预后 血管生成低和 T 细胞亚型高的患者最有可能从 ICB 治疗中受益 有很大一部分患者对免疫检查点阻断没有反应。萨勃拉曼尼亚等人。通过计算分析表明,在各种实体瘤类型中,肿瘤血管生成和 T 细胞免疫的基线特征可以预测免疫检查点阻断治疗的治疗结果。
Immune checkpoint blockade (ICB) therapy has revolutionized cancer treatment. However, only a fraction of patients respond to ICB therapy. Accurate prediction of patients to likely respond to ICB would maximize the efficacy of ICB therapy. The tumor microenvironment (TME) dictates tumor progression and therapy outcome. Here, we classify the TME by analyzing the transcriptome from 11,069 cancer patients based on angiogenesis and T cell activity. We find three distinct angio-immune TME subtypes conserved across 30 non-hematological cancers. There is a clear inverse relationship between angiogenesis and anti-tumor immunity in TME. Remarkably, patients displaying TME with low angiogenesis with strong anti-tumor immunity show the most significant responses to ICB therapy in four cancer types. Re-evaluation of the renal cell carcinoma clinical trials provides compelling evidence that the baseline angio-immune state is robustly predictive of ICB responses. This study offers a rationale for incorporating baseline angio-immune scores for future ICB treatment strategies. Angiogenesis and T cell immunity are inversely correlated in the tumor microenvironment Angiogenesis and T cell activity are used to stratify the tumor microenvironment Angio-immune subtypes are prognostic of survival post-anti-PD1/L1 treatment Patients with low angiogenic and high T cell subtypes most likely to benefit from ICB treatment There is a large proportion of patients who do not mount responses to immune checkpoint blockade. Subramanian et al. show through a computational analysis that, across solid tumor types, baseline characteristics of tumor angiogenesis and T cell immunity can predict therapeutic outcomes to immune checkpoint blockade treatment.
