晚期肺癌免疫检查点抑制剂治疗的前景

2021-09-09 网络 网络

肿瘤免疫检查点疗法(ICIs)的发现和应用,是肿瘤治疗领域里程碑式的事件。

肿瘤免疫检查点疗法(ICIs)的发现和应用,是肿瘤治疗领域里程碑式的事件。美国科学家James P.Allison 和日本科学家TasukuHonjo更因此获得2018年诺贝尔生理学和医学奖。它的出现为非小细胞肺癌(NSCLC)患者带来了显著的生存获益,且毒性较低。

众所周知,肺癌的主要亚型除了NSCLC外,还包括小细胞肺癌(SCLC)。然而,近年来评估ICI治疗的有效性与安全性多集中在NSCLC上,SCLC仿佛被忽视了,且缺乏其在NSCLC与SCLC中应用的疗效与安全性对比数据。为此,有研究者系统性梳理了ICIs在晚期肺癌中的具体疗效与安全性,同时比较了MSCLC和SCLC免疫疗法的益处和风险,其结果于8月28日发表在BMC Cancer

研究者共纳入了2010年1月-2021年5月符合条件的38个随机对照试验、41项研究。其中八项研究探索了ICI与标准护理化疗(SOC)在SCLC患者上中的疗效,其余33项研究进行了NSCLC患者分别接受ICI和SOC疗法的有效性和安全性数据对比。

 

结果:

对于NSCLC和SCLC患者而言,ICI仍然是理想的治疗方案,无论是生存获益还是毒性反应都要优于SOC。

推荐ICI+SOC是SCLC患者的最佳一线治疗方案。

推荐抗PD-1/PD-L1+SOC以及CTLA-4抗体用于一线和后续治疗中没有突变基因的NSCLC患者。

不推荐免疫疗法作为SCLC后续治疗的标准策略。
