Current pivotal phase 3 studies have permanently changed the first-line treatment landscape in metastatic renal cell carcinoma. These studies showed that immune checkpoint combinations were more efficacious than sunitinib, a previous standard of care. Nivolumab plus ipilimumab is characterized by a survival advantage, a high rate of complete response and durable remission in patients with intermediate and unfavorable prognosis. Despite frequent immune-mediated side effects, fewer symptoms and a better quality of life were observed compared to sunitinib. Pembrolizumab or avelumab plus axitinib were characterized by an improved PFS and a high response rate with a low rate of intrinsic resistance. In addition, a significant survival benefit was achieved with pembrolizumab plus axitinib. The side effect profile is driven by the "chronic" toxicity of axitinib, but there is additional risk of immune-mediated side effects of the PD-1/PD-L1 immune checkpoint inhibitors. The quality-of-life data published so far do not suggest any improvement compared to the previous standard sunitinib. The PD-1/PD-L1 immune-check-point inhibitors thus form the "backbone" of the first-line therapy of metastatic renal cell carcinoma. Monotherapy with VEGFR-TKI remains an option in cases with contraindications and possibly for subgroups with favorable prognosis.
当前关键的3期研究已永久性改变了转移性肾细胞癌的一线治疗格局。这些研究表明,免疫检查点联合疗法比先前的标准治疗药物舒尼替尼更有效。纳武利尤单抗联合伊匹木单抗的特点是具有生存优势,在预后中等及不良的患者中完全缓解率高且缓解持久。尽管免疫介导的副作用常见,但与舒尼替尼相比,观察到的症状更少,生活质量更高。帕博利珠单抗或阿维鲁单抗联合阿昔替尼的特点是无进展生存期改善、缓解率高且内在耐药率低。此外,帕博利珠单抗联合阿昔替尼可带来显著的生存获益。副作用特征由阿昔替尼的“慢性”毒性驱动,但PD-1/PD-L1免疫检查点抑制剂还存在免疫介导副作用的额外风险。迄今为止公布的生活质量数据未显示与先前的标准药物舒尼替尼相比有任何改善。因此,PD-1/PD-L1免疫检查点抑制剂构成了转移性肾细胞癌一线治疗的“支柱”。对于有禁忌证的病例以及可能预后良好的亚组患者,VEGFR-TKI单药治疗仍是一种选择。
