ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of capecitabine metronomic chemotherapy combined with aromatase
inhibitor (AI) versus AI monotherapy as first-line treatment for hormone receptor-positive (HR+)/human epidermal growth factor
receptor 2-negative (HER2-) metastatic breast cancer, thereby providing evidence-based support for clinical therapeutic decision-
making and healthcare policy formulation. METHODS Based on the MECCA trial, a partitioned survival model was constructed
using a 4-week cycle length to simulate outcomes over patients’ lifetime. The model outputs included total costs, quality-adjusted
life year (QALY), and incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed to validate the robustness
of base-case results, while scenario analyses examined the cost-effectiveness of both treatment strategies under 10-year, 20-year,
and lifetime time horizons. RESULTS With the willingness-to-pay (WTP) threshold set at 1 times China’s 2024 per capita gross
domestic product (GDP) (95 749 yuan/QALY), patients receiving capecitabine metronomic chemotherapy combined with AI
regimen gained incremental utility (0.66 QALYs) while incurring higher costs, with ICER of 27 684.85 yuan/QALY. Results of the
one-way sensitivity analysis showed that factors with significant impacts on ICER included the cost discount rate, drug costs of the
capecitabine metronomic chemotherapy combined with AI
