ABSTRACT
BACKGROUND:
The combination of dual-targeted human epidermal growth factor receptor 2 (HER2) therapy and chemotherapy is the standard first-line regimen for recurrent/metastatic breast cancer (mBC). However, the toxicity of such combination therapy can lead to some patients being unable to tolerate adverse events or bear treatment costs. As a novel irreversible pan-ErbB receptor TKI (pyrotinib), can the dual oral administration of pyrotinib plus capetabine (PyroC) provide first-line survival benefits and serve as a more affordable treatment option?METHODS:
This real-world retrospective study included patients diagnosed with HER2-positive mBC who received PyroC as a first-line treatment at West China Hospital between May 2018 and July 2023. The survival data and toxicity profiles were reported in this study.RESULTS:
A total of 64 patients received PyroC as first-line therapy. The median progression-free survival (PFS) was 19.6 months (95% CI 15.0-27.2), while overall survival (OS) has not yet been reached. Kaplan-Meier analysis indicated that age (≥60, p = 0.03) and metastasis sites (p = 0.004) were related to poor efficacy of PyroC, while there was no relationship between effectiveness and menstrual status, hormone receptor (HR) status or previous treatment with anti-HER2 therapy. Furthermore, the objective response rate (ORR) and disease control rate (DCR) were 79.7% and 98.4%, respectively. Of the patients, 78.1% reported treatment-related adverse events (TRAEs). The predominant adverse events were diarrhea (n = 46, 71.9%) and hand-foot syndrome (n = 10, 15.6%).CONCLUSION:
The dual oral administration regimen (PyroC) has a promising ORR or PFS in HER2-positive mBC patients, with an acceptable safety profile and convenience.Palabras clave
