          摘  要  目的  从我国卫生体系角度出发,评价德曲妥珠单抗方案对比医生选择化疗(TPC)方案二线治疗人表皮生长因子受体2
         (HER-2)低表达晚期乳腺癌的经济性。方法  基于DESTINY-Breast04临床试验数据构建动态Markov模型,模拟时限为10年,循
          环周期为3周。以成本、质量调整生命年(QALY)、增量成本-效果比(ICER)作为模型产出指标,采用5%的贴现率,以3倍2023年
          我国人均国内生产总值(GDP)作为意愿支付(WTP)阈值,采用成本-效用分析法分析激素受体阳性队列和所有患者队列中两种治
          疗方案的经济性,再通过不确定性分析验证基础分析结果的稳健性。结果  基础分析结果显示,德曲妥珠单抗方案与TPC方案相
          比,在激素受体阳性队列和所有患者队列中的 ICER 值分别为 1 045 655.76、906 404.99 元/QALY,均高于 WTP 阈值(268 074
          元/QALY)。单因素敏感性分析结果显示,疾病无进展状态效用值、德曲妥珠单抗价格、疾病进展状态效用值等参数对模型结果影
          响较大。概率敏感性分析结果显示,当WTP阈值为3倍2023年我国人均GDP时,德曲妥珠单抗方案具有经济性的概率为0。情
          境分析结果显示,在考虑援助计划时,德曲妥珠单抗方案具有经济性的概率为0;当德曲妥珠单抗价格降低70%时,该方案具有经
          济性的概率显著提高至82.80%。结论  在以3倍2023年我国人均GDP作为WTP阈值时,德曲妥珠单抗方案相对于TPC方案二线
          治疗HER-2低表达晚期乳腺癌不具有经济性;按地区适当降低德曲妥珠单抗的价格,可以提高其经济性。

          ABSTRACT   OBJECTIVE  To  evaluate  the  economics  of  trastuzumab  deruxtecan  versus  the  physician-selected  chemotherapy
         (TPC)  regimen  in  the  second-line  treatment  of  advanced  breast  cancer  with  epidermal  growth  factor  receptor  2 (HER-2)  low
          expression  from  the  perspective  of  the  Chinese  healthcare  system.  METHODS  Based  on  the  data  of  DESTINY-Breast04  clinical
          trial,  the  dynamic  Markov  model  was  constructed.  The  time  frame  of  the  model  simulation  was  10  years,  and  the  cycle  was  3
          weeks.  Taking  cost,  quality-adjusted  life  year (QALY)  and  incremental  cost-effectiveness  ratio (ICER)  as  the  model  output
          indicators, the discount rate of 5% was applied, and 3 times China’s per capita gross domestic product (GDP) in 2023 was taken
          as  the  willingness-to-pay (WTP)  threshold  value.  Cost-utility  analysis  was  used  to  evaluate  the  economics  of  the  two  treatment
                                                             regiments  in  the  hormone  receptor-positive  cohort  and  all
