TITLE: Immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy in the treatment of early-stage triple-negative breast cancer:a meta-analysis
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、CochraneLibrary、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Stata17.0软件进行Meta分析。结果共纳入5项RCT,共计1498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, 1.87), P=0.03], and the incidence of treatment discontinuation due to AEs [RR=1.45, 95%CI (1.19, 1.76), P=0.01] were significantly higher in the experimental group than control group. There were no statistically significant difference in pCR in patients with negative PD-1/PD-L1[RR= E-mail:biejun23@126.com 1.26, 95%CI (0.98, 1.62), P=0.08] and pCR in patients with negative lymph nodes [RR=1.14, 95%CI (0.97, 1.33), P=0.17] between the two groups. CONCLUSIONS Immune checkpoint inhibitors combined with neoadjuvant chemotherapy and adjuvant chemotherapy demonstrates significant efficacy in early-stage TNBC patients, with more pronounced benefits observed in those who are PD-1/PD-L1 positive and lymph node- positive. However, the incidence of AEs is relatively high.
