          摘   要  目的  评价特瑞普利单抗联合紫杉醇(白蛋白结合型)治疗转移性或复发性三阴性乳腺癌(TNBC)的经济性。方法  根据
          TORCHLIGHT试验数据,建立包括无进展生存、疾病进展和死亡的三状态分区生存模型,模拟周期为21 d,研究时限为10年,贴
          现率为5%,以质量调整生命年(QALY)和成本为产出指标,采用成本-效果分析法计算特瑞普利单抗联合紫杉醇(白蛋白结合型)
          相比安慰剂联合紫杉醇(白蛋白结合型)的增量成本-效果比(ICER)。以 3 倍我国 2023 年人均国内生产总值(GDP)为意愿支付
         (WTP)阈值(268 074元/QALY),评价上述两种方案的经济性,并进行敏感性分析。结果  特瑞普利单抗联合紫杉醇(白蛋白结合
          型)对比安慰剂联合紫杉醇(白蛋白结合型)治疗我国转移性或复发性TNBC患者的ICER为176 347.17元/QALY,低于本研究设
          定的WTP阈值,证明该方案具有经济性。单因素敏感性分析结果显示,特瑞普利单抗成本、贴现率、无进展生存状态效用值等参
          数对ICER的影响较大;概率敏感性分析结果表明基础分析结果稳健。结论  以3倍我国2023年人均GDP作为WTP阈值时,相比
          安慰剂联合紫杉醇(白蛋白结合型)方案,特瑞普利单抗联合紫杉醇(白蛋白结合型)治疗转移性或复发性TNBC具有经济性。

          Cost-effectiveness  analysis  of  toripalimab  combined  with  paclitaxel  in  the  treatment  of  metastatic  or
          recurrent triple-negative breast cancer

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  toripalimab  combined  with  paclitaxel (albumin  binding  type)  in
          the  treatment  of  metastatic  or  recurrent  triple-negative  breast  cancer (TNBC).  METHODS  Based  on  the  data  of  TORCHLIGHT
          clinical  trial,  a  three-state  partitioned  survival  model  including  progression-free  survival,  disease  progression,  and  death  was
          established.  The  simulation  cycle  was  21  days,  the  study  duration  was  10  years,  and  the  discount  rate  was  5%.  Using  quality-
          adjusted  life  year (QALY)  and  cost  as  output  indicators,  a  cost-effectiveness  analysis  method  was  adopted  to  calculate  the
          incremental  cost-effectiveness  ratio (ICER)  of  toripalimab  combined  with  paclitaxel (albumin  binding  type)  versus  placebo
          combined with paclitaxel (albumin binding type). Using three times the per capita gross domestic product (GDP) of China in 2023
          as the willingness-to-pay(WTP) threshold(268 074 yuan/QALY), the cost-effectiveness of the above two regimens was evaluated,
          and the sensitivity analysis was conducted. RESULTS ICER of toripalimab combined with paclitaxel (albumin binding type) versus
          placebo  combined  with  paclitaxel (albumin  binding  type)  in  the  treatment  of  Chinese  metastatic  or  recurrent  TNBC  patients  was
          176  347.17  yuan/QALY,  which  was  lower  than  the  WTP  threshold  set  in  this  study,  demonstrating  the  cost-effectiveness  of  this
          regimen.  The  results  of  the  single-factor  sensitivity  analysis  showed  that  the  parameters  such  as  the  cost  of  toripalimab,  discount
          rate,  and  utility  value  of  the  progression-free  survival  state  had  a  great  impact  on  the  ICER.  The  results  of  the  probabilistic
          sensitivity  analysis  indicated  that  the  results  of  the  basic  analysis  were  robust.  CONCLUSIONS  When  three  times  the  per  capita
          GDP  of  China  in  2023  is  used  as  the  WTP  threshold,  compared  with  the  regimen  of  placebo  combined  with  paclitaxel (albumin
          binding  type),  toripalimab  combined  with  paclitaxel (albumin  binding  type)  is  cost-effective  in  the  treatment  of  metastatic  or
          recurrent TNBC.
