          摘  要  目的  评估卡培他滨节拍化疗联合芳香化酶抑制剂(AI)对比单用AI一线治疗激素受体阳性(HR+)/人表皮生长因子受体
          2阴性(HER2-)转移性乳腺癌的经济性,为临床用药方案的选择及医疗卫生决策提供依据。方法  基于MECCA试验构建分区生
          存模型,以4周为循环周期,模拟至患者终身;以总成本、质量调整生命年(QALY)和增量成本-效果比(ICER)作为模型产出指标。
          利用敏感性分析验证基础分析结果的稳健性,并通过情境分析考察了10年、20年、终身研究时限下两种方案的经济性。结果  在
          以1倍我国2024年人均国内生产总值(GDP)为意愿支付阈值(95 749元/QALY)的前提下,使用卡培他滨节拍化疗联合AI方案的
          患者在获得增量效用(0.66 QALYs)的同时也需要支付更多的成本,ICER为27 684.85元/QALY。单因素敏感性分析结果显示,对
          ICER值影响较大的因素有成本贴现率、卡培他滨节拍化疗联合AI组药品成本、无进展生存状态效用值、随访成本和后续稳定期
          治疗成本。概率敏感性分析结果显示,当 WTP 阈值≥49 250 元/QALY 时,卡培他滨节拍化疗联合 AI 方案具有经济性的概率为
          100%。情境分析结果表明,卡培他滨节拍化疗联合 AI 方案在 10 年、20 年、终身研究时限下均较单用 AI 方案更具有经济性。
          结论  在以 1 倍我国 2024 年人均 GDP 为意愿支付阈值的前提下,与单用 AI 方案相比,卡培他滨节拍化疗联合 AI 方案一线治疗
          HR+/HER2-转移性乳腺癌更具有经济性。

          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
