Efficacy and Safety of Small-Molecule Human Epidermal Growth Factor Receptor 2 (HER2)-Targeting Tyrosine Kinase Inhibitor-Containing Regimens for Metastatic HER2-Positive Breast Cancer: A Systematic Review and Network Meta-Analysis of Randomized Clinical

Abstract

To simultaneously compare the efficacy and safety of small-molecule Human Epidermal Growth Factor Receptor 2 (HER2)-targeting tyrosine kinase inhibitor (TKI)-containing regimens for metastatic HER2-positive breast neoplasm. MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Web of Science, and Scopus databases were systematically searched to identify randomized clinical trials (RCT) that investigated the difference in overall survival (OS), progression-free survival (PFS), overall response (OR), recurrence in central nervous system/brain metastasis (RCNS), total and grade 3 or 4 adverse events (AE), diarrheal AEs, and cardiac AEs of small-molecule HER2-targeting TKI-containing regimens in women with metastatic HER2-positive breast carcinoma. The revised Cochrane risk-of-bias tool for randomized trials (RoB2) was used to evaluate the risk of bias in the included studies. When applicable, pooled network estimates were synthesized by frequentist random-effect network meta-analysis using Stata MP Software (version 14). Twenty-three studies comprising 7497 eligible patients were included. In all, 17 small-molecule anti-HER2 TKI (Lapatinib, Neratinib, Afatinib, Pyrotinib, and Tucatinib)-containing and 10 other regimens were compared. In terms of increasing OS, the Pyrotinib/Capecitabine combination ranked first best among small-molecule HER2-targeting TKI-containing regimens. In terms of PFS, the Pyrotinib/Capecitabine combination prolonged PFS in comparison with all other small-molecule anti-HER2 TKI-containing regimens in the network. In the corresponding network, Pyrotinib/Capecitabine and Tucatinib/Trastuzumab/Capecitabine combinations ranked first best and second best among small-molecule anti-HER2 TKI-containing regimens. In terms of AE, the Tucatinib/Trastuzumab/Capecitabine combination ranked the highest for AE occurrence. Pyrotinib/Capecitabine and Tucatinib/Trastuzumab/Capecitabine combinations seemed to be the most efficacious small-molecule HER2-targeting TKI-containing regimens in metastatic HER2-positive breast cancer.
