欧美和中国CSCO的肺癌诊疗指南皆以最高级别推荐帕博利珠单抗单药一线治疗优选NSCLC人群的精准免疫治疗[8-10] 。 值得一提的是 , K药的精准免疫之旅并未止步于以PD-L1作为伴随诊断 。 继2017年5月K药在美国获批单药后线治疗微卫星高度不稳定(MSI-H)/错配修复缺陷(dMMR)实体瘤的适应证后 , K药今年6月16日在美国又获批单药后线治疗肿瘤突变负荷高(TMB-H)实体瘤[11] 。 因此 , 在全球范围内 , K药是唯一获批分别以PD-L1、MSI/dMMR、TMB诊断结果来精准指导临床用药的免疫治疗方案 , 是当之无愧的“精准免疫之王” 。 2020年的ESMO之后 , 国内的临床医生在经历KEYNOTE-024研究结果的再次“洗礼”之后 , 是否会更“苛刻”质询“基于PD-1/PD-L1单抗的所有治疗方案能为我国患者带来长期生存”?这将是KEYNOTE-024的一个终极看点 , 也决定了KEYNOTE-024研究结果在中国肿瘤免疫治疗历史上将占据的地位 。【医学界肿瘤频道|K药为什么姓“牛”】参考文献
