Abstract:

摘要 目的 系统评价PD-1/PD-L1抑制剂对比化疗一线治疗晚期非小细胞肺癌的疗效及安全性。方法 通过Web of science等国内外数据库,ASCO会议摘要及杂志筛选文献,进行Meta分析。结果 纳入7项RCT研究,4 101例患者,荟萃分析显示抑制剂联合化疗对比化疗可显著延长患者的PFS(HR=0.59, 95%CI: 0.50~0.70, P<0.00001)、OS(HR=0.65, 95%CI: 0.46~0.92, P=0.02)及ORR(RR=1.72, 95%CI: 1.13~2.62, P=0.01)。亚组分析显示,抑制剂联合化疗可显著延长PFS及OS,且PD-L1表达程度越高,疗效获益越显著。而单药抑制剂对比化疗在延长晚期NSCLC患者的PFS(HR=0.87, 95%CI: 0.57~1.31, P=0.50)、OS(HR=0.82, 95%CI: 0.65~1.03, P=0.09)及提高ORR(RR=1.12, 95%CI: 0.55~2.28, P=0.76)方面两组差异无统计学意义。与化疗相比,单药抑制剂一线治疗PD-L1高表达的晚期NSCLC患者可显著延长OS,但在延长PFS方面未见明显优势。与化疗组相比,抑制剂联合化疗组3~4级不良反应发生率无明显改善(HR=1.09,95%CI: 0.99~1.20, P=0.09),而单药PD-1/PD-L1抑制剂组3~4级不良反应发生率低(RR=0.43, 95%CI: 0.36~0.52, P<0.00001)。 结论 PD-1/PD-L1抑制剂联合化疗一线治疗晚期NSCLC患者疗效优于化疗方案;PD-L1高表达者单药PD-1/PD-L1抑制剂可作为一线治疗的优先选择,且具有良好的安全性
