In patients with advanced clear cell renal cell carcinoma, despite the undoubted benefits from immune checkpoint inhibitor (ICI)-based therapies over monotherapies of angiogenic/mTOR inhibitors in the intention-to-treat population, approximately a quarter of the patients can scarcely gain advantage from ICIs, prompting the search for predictive biomarkers for patient selection.
Clinical and multi-omic data of 2428 ccRCC patients were obtained from The Cancer Genome Atlas (TCGA, n = 537), JAVELIN Renal 101 (avelumab plus axitinib vs. sunitinib, n = 885), and CheckMate-009/010/025 (nivolumab vs. everolimus, n = 1006).
BAP1 mutations were associated with large progression-free survival (PFS) benefits from ICI-based immunotherapies over sunitinib/everolimus (pooled estimate of interaction HR = 0.71, 95% CI 0.51-0.99, P = 0.045). Using the top 20 BAP1 mutation-associated differentially expressed genes (DEGs) generated from the TCGA cohort, we developed the BAP1-score, negatively correlated with angiogenesis and positively correlated with multiple immune-related signatures concerning immune cell infiltration, antigen presentation, B/T cell receptor, interleukin, programmed death-1, and interferon. A high BAP1-score indicated remarkable PFS benefits from ICI-based immunotherapies over angiogenic/mTOR inhibitors (avelumab plus axitinib vs. sunitinib: HR = 0.55, 95% CI 0.43-0.70, P < 0.001; nivolumab vs. everolimus: HR = 0.72, 95% CI 0.52-1.00, P = 0.045), while these benefits were negligible in the low BAP1-score subgroup (HR = 1.16 and 1.02, respectively).
In advanced ccRCCs, the BAP1-score is a biologically and clinically significant predictor of immune microenvironment and the clinical benefits from ICI-based immunotherapies over angiogenic/mTOR inhibitors, demonstrating its potential utility in optimizing the personalized therapeutic strategies in patients with advanced ccRCC.
在晚期透明细胞肾细胞癌患者中,尽管免疫检查点抑制剂(ICI)治疗在治疗意向人群中明显优于血管生成/mTOR 抑制剂的单药治疗,但仍有约四分之一的患者几乎无法从 ICI 中获益,因此需要寻找预测生物标志物来进行患者选择。
从癌症基因组图谱(TCGA,n=537)、JAVELIN Renal 101(avelumab 加 axitinib 与 sunitinib,n=885)和 CheckMate-009/010/025(nivolumab 与 everolimus,n=1006)获得了 2428 例 ccRCC 患者的临床和多组学数据。
BAP1 突变与 ICI 为基础的免疫治疗与 sunitinib/everolimus 相比具有较大的无进展生存期(PFS)获益(交互 HR=0.71,95%CI 0.51-0.99,P=0.045)。利用 TCGA 队列生成的 top 20 个 BAP1 突变相关差异表达基因(DEGs),我们开发了 BAP1 评分,该评分与血管生成呈负相关,与多个免疫相关特征呈正相关,包括免疫细胞浸润、抗原呈递、B/T 细胞受体、白细胞介素、程序性死亡受体-1 和干扰素。高 BAP1 评分与 ICI 为基础的免疫治疗与血管生成/mTOR 抑制剂相比具有显著的 PFS 获益(avelumab 加 axitinib 与 sunitinib:HR=0.55,95%CI 0.43-0.70,P<0.001;nivolumab 与 everolimus:HR=0.72,95%CI 0.52-1.00,P=0.045),而在低 BAP1 评分亚组中获益微不足道(HR=1.16 和 1.02)。
在晚期 ccRCC 中,BAP1 评分是免疫微环境的生物学和临床意义上的预测因子,也是 ICI 为基础的免疫治疗与血管生成/mTOR 抑制剂相比的临床获益的预测因子,表明其在优化晚期 ccRCC 患者的个体化治疗策略方面具有潜在的应用价值。
