          摘   要  目的  从我国卫生体系角度出发,评估芦康沙妥珠单抗(ST)对比医生选择的化疗方案(TPC)用于转移性三阴性乳腺癌
         (mTNBC)二线及后线治疗的经济性。方法  基于OptiTROP-Breast01研究,根据mTNBC疾病发展过程构建分区生存模型,设置循
          环周期为4周,模拟时限为10年,贴现率为5%。以质量调整生命年(QALY)和总成本作为产出指标,计算ST方案相对于TPC用
          于mTNBC二线及后线治疗的增量成本-效果比(ICER),利用敏感性分析验证基础分析结果的稳健性。结果  在以3倍我国2024
          年人均国内生产总值(GDP)为意愿支付阈值(287 247元/QALY)的前提下,使用ST方案的患者在获得增量效用(0.42 QALY)的同
          时也需要支付更多成本,ICER为205 562.07元/QALY,低于意愿支付阈值,表明ST方案相对于TPC更具经济性。单因素敏感性分
          析结果显示,无进展生存期状态健康效用值和ST成本对ICER值影响较大。概率敏感性分析和情况分析结果表明基础分析结果
          稳健。结论  从我国卫生体系角度出发,以3倍我国人均GDP为意愿支付阈值,ST方案相对于TPC用于我国mTNBC患者二线及
          以后线治疗更具经济性。

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  sacituzumab  tirumotecan (ST)  versus  chemotherapy  treatment
          physician’s  choice (TPC)  as  second-line  and  later-line  treatment  for  metastatic  triple-negative  breast  cancer (mTNBC)  from  the
          perspective of China’s healthcare system. METHODS A partitioned survival model was constructed based on the OptiTROP-Breast 01
          trial,  with  a  cycle  length  of  4  weeks  and  a  time  horizon  of  10  years,  applying  a  5%  discount  rate.  Quality  adjusted  life  year
         (QALY)  and  costs  were  used  as  outcome  measures,  and  the  incremental  cost-effectiveness  ratio (ICER)  of  ST  versus  TPC  for
          second-line and later-line treatment of mTNBC was calculated. Sensitivity analyses were conducted to validate the robustness of the
          base-case  results.  RESULTS  At  a  willingness-to-pay  threshold (WTP)  of  3  times  China’s  2024  per  capita  gross  domestic  product
         (GDP) (287 247 yuan/QALY), patients receiving ST gained incremental utility (0.42 QALY) at a higher cost, yielding an ICER
          of  205  562.07  yuan/QALY,  which  was  lower  than  WTP,  indicating  that  ST  was  more  cost-effective  compared  to  TPC.  One-way
          sensitivity  analysis  revealed  that  key  factors  influencing  the  ICER  included  the  utility  value  of  progression-free  survival  and  the
          price of ST. Probabilistic sensitivity analysis and scenario analysis showed that the base-case results were robust. CONCLUSIONS

          From  the  perspective  of  China’s  healthcare  system,  at  a WTP  of  3  times  China’s  per  capita  GDP,  ST  is  more  cost-effective  than
                                                              TPC as second-line and later-line treatment for mTNBC.
