Abstract:
[摘 要] 目的:系统评价单药程序性死亡受体1(PD-1)抑制剂对比化疗二线治疗晚期食管鳞状细胞癌(ESCC)患者的疗效及安全性,以期为临床决策提供最佳循证医学证据。方法:计算机检索The Cochrane Library、Web of Science、PubMed、EMbase、CNKI和万方等数据库,同时检索J Clin Oncol、N England Oncol、Lancet Oncol等杂志以及ASCO、EMSO会议摘要中有关单药PD-1抑制剂对比传统化疗二线治疗晚期ESCC患者的临床随机对照试验(RCT),筛选文献,提取资料,采用RevMan5.3进行Meta分析。结果:共纳入5项RCT研究(1 732例患者)。与化疗组比,单药PD-1抑制剂二线治疗晚期ESCC可显著延长患者的总生存期(OS)(HR=0.75,95% CI:0.67~0.83,P<0.000 01)。以PD-L1不同表达程度进行亚组分析,在延长OS方面,TPS<1%时,单药PD-1抑制剂二线治疗晚期ESCC无明显优势;而TPS≥1%、TPS<5%、TPS≥5%、TPS<10%、TPS≥10%时,单药PD-1抑制剂二线治疗均可显著延长晚期ESCC患者的OS,且PD-L1表达程度越高,疗效获益更显著。然而,与化疗组比,单药PD-1抑制剂在延长晚期ESCC患者的无进展生存期(PFS)(HR=0.93,95% CI:0.79~1.10,P=0.41)及提高客观有效率(ORR)(RR=1.62,95% CI:0.95~2.74,P=0.07)等方面,差异均无统计学意义。但单药PD-1抑制剂组3~5级不良反应发生率低(RR=0.37,95% CI:0.28~0.50,P<0.000 01)。结论:单药PD-1抑制剂二线治疗晚期ESCC患者可显著延长患者的OS;PD-L1高表达者PD-1抑制剂可作为二线治疗的优先选择,且具有良好的安全性。
