摘 要 目的 评价免疫检查点抑制剂(ICIs)联合新辅助及辅助化疗用于早期三阴性乳腺癌(TNBC)的有效性和安全性。方法
检索PubMed、Embase、Cochrane Library、中国知网、万方数据,收集ICIs联合新辅助及辅助化疗(试验组)对比新辅助化疗及辅助
化疗(对照组)用于早期 TNBC 的随机对照试验(RCT)。筛选文献、提取资料,评价文献质量后,采用 Stata 17.0 软件进行 Meta分
析。结果 共纳入 5 项 RCT,共计 1 498 例患者。Meta 分析结果显示,试验组患者的病理完全缓解率(pCR)[RR=1.34,95%CI
(1.09,1.63),P=0.03]、程序性死亡受体1(PD-1)及其配体(PD-L1)阳性患者的pCR[RR=1.33,95%CI(1.16,1.51),P=0.01]、淋巴
结阳性患者的 pCR[RR=1.56,95%CI(1.27,1.93),P=0.01]、3~4 级不良事件(AE)发生率[RR=1.07,95%CI(1.01,1.14),P=
0.04]、严重 AE 发生率[RR=1.57,95%CI(1.31,1.87),P=0.03]、因 AE 停药发生率[RR=1.45,95%CI(1.19,1.76),P=0.01]均显著
高于对照组;两组 PD-1/PD-L1 阴性患者的 pCR[RR=1.26,95%CI(0.98,1.62),P=0.08]和淋巴结阴性患者的 pCR[RR=1.14,
95%CI(0.97,1.33),P=0.17]比较,差异均无统计学意义。结论 ICIs联合新辅助及辅助化疗用于早期TNBC患者的疗效显著,且
PD-1/PD-L1阳性和淋巴结阳性的患者获益更显著,但AE发生率较高。

ABSTRACT OBJECTIVE To evaluate the efficacy and safety of immune checkpoint inhibitors combined with neoadjuvant
chemotherapy and adjuvant chemotherapy in the treatment of early-stage triple-negative breast cancer (TNBC). METHODS A
systematic search was conducted in PubMed, Embase, Cochrane Library, CNKI, and Wanfang Data to collect randomized
controlled trials (RCT) on the use of immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant
chemotherapy (experimental group) versus neoadjuvant chemotherapy and adjuvant chemotherapy (control group) in the treatment
of TNBC. After literature screening, data extraction and literature quality evaluation, meta-analysis was performed using Stata 17.0.
RESULTS A total of 5 RCT involving 1 498 patients were included. The meta-analysis results showed that the pathological
complete response rate (pCR) [RR=1.34, 95%CI (1.09, 1.63), P=0.03], pCR in patients with positive programmed death-1
(PD-1) and its ligand (PD-L1) [RR=1.33, 95%CI (1.16, 1.51), P=0.01], pCR in patients with positive lymph nodes [RR=
1.56, 95%CI (1.27, 1.93), P=0.01], the incidence of grade 3-4 adverse events (AEs) [RR=1.07, 95%CI (1.01, 1.14), P=
0.04], the incidence of serious AEs [RR=1.57, 95%CI (1.31,
