果显示,试验组患者的无进展生存期(PFS)[HR=0.76,95%CI(0.69,0.83),P<0.000 01]、总生存期(OS)[HR=0.87,95%CI(0.81,
0.93),P<0.000 1]、临床获益率(CBR)[OR=2.70,95%CI(1.15,6.33),P=0.02]均显著长于/高于对照组;两组患者的客观缓解率
(ORR)比较,差异无统计学意义[OR=2.34,95%CI(0.59,9.33),P=0.23]。亚组分析结果显示,试验组人表皮生长因子受体-2
(HER2)阳性、HER2阴性患者的PFS以及HER2阳性患者的OS均显著高于对照组(P<0.05)。试验组患者的贫血、天冬氨酸转氨
酶升高发生率均显著高于对照组(P<0.05)。敏感性分析结果显示,以PFS、OS、ORR为指标时,所得结果较稳健;以CBR为指标
时,所得结果缺乏稳健性。结论 ADC类药物用于乳腺癌的疗效显著,但会增加贫血和天冬氨酸转氨酶升高的发生风险。

ABSTRACT OBJECTIVE To evaluate the efficacy and safety of antibody-drug conjugates (ADC) in the treatment of breast
cancer, so as to provide an evidence-based reference for clinical medication. METHODS Retrieved from CNKI, Wanfang
database, VIP, PubMed, the Cochrane Library, Embase, and Web of Science, randomized controlled trials (RCTs) about
trastuzumab emtansine, trastuzumab deruxtecan and sacituzumab govitecan (trial group) versus chemotherapy or other anti-tumor
drugs (control group), were collected during the inception to April 2023. After screening the literature, extracting data, and
evaluating the quality of the literature, a meta-analysis was conducted by using RevMan 5.4.1 software. RESULTS A total of 8
RCTs were included, with a total of 5 577 patients. The results of the meta-analysis showed that the progression-free survival
(PFS) [HR=0.76, 95%CI (0.69, 0.83), P<0.000 01], overall survival (OS) [HR=0.87, 95%CI (0.81, 0.93), P<0.000 1], and
clinical benefit rate (CBR) [OR=2.70, 95%CI (1.15, 6.33), P=0.02] of the trial group were significantly higher than control
group. There was no statistically significant difference in objective response rate (ORR) between the two groups [OR=2.34,
95%CI (0.59, 9.33), P=0.23]. The results of subgroup analysis showed that the PFS of HER2-positive patients and HER2-negative
patients, and the OS of HER2-positive patients in the trial group were significantly higher than control group (P<0.05). The
incidence of anemia and increase of aspartic acid transaminase (AST) in the trial group was significantly higher than control group
(P<0.05). The results of sensitivity analysis showed that the results obtained with PFS, OS, and ORR as indicators were relatively
robust, while the results obtained with CBR as indicators lacked robustness. CONCLUSIONS ADC drugs have significant effects
on breast cancer, but will increase the risk of anemia and elevated AST.
