          摘  要  目的  从中国卫生体系角度出发,评估贝莫苏拜单抗联合安罗替尼和化疗方案一线治疗广泛期小细胞肺癌(ES-SCLC)的
          经济性。方法  根据ETER701研究数据构建分区生存模型,循环周期为3周,模拟ES-SCLC患者采用贝莫苏拜单抗联合安罗替尼
          和化疗方案或单纯化疗方案治疗10年的总成本、质量调整生命年(QALY)及增量成本-效果比(ICER),并采用单因素敏感性分析
          和概率敏感性分析验证模型的稳健性。意愿支付(WTP)阈值为3倍2023年我国人均国内生产总值(GDP),即268 074元/QALY。
          结果  相比于单纯化疗方案,贝莫苏拜单抗联合安罗替尼和化疗方案可多获得 0.438 QALY,成本则高出 403 505.55 元,ICER 为
          922 031.37元/QALY,高于本研究设定的WTP阈值。单因素敏感性分析结果显示,贝莫苏拜单抗成本、无进展生存期状态的效用
          值及贴现率对基础分析结果的影响较大;概率敏感性分析结果证实该模型稳健,且贝莫苏拜单抗降价75.4%时,联合方案才具有
          经济性。结论  从我国卫生体系角度出发,贝莫苏拜单抗联合安罗替尼和化疗方案一线治疗ES-SCLC当前不具有经济性。

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-utility  of  benmelstobart  combined  with  anlotinib  and  chemotherapy  as  first-line
          treatment  for  extensive-stage  small  cell  lung  cancer (ES-SCLC)  from  the  perspective  of  China’s  healthcare  system.  METHODS
          Based on the data from the ETER 701 study, a partitioned survival model was constructed with a cycle of 3 weeks to simulate the
          total cost, quality-adjusted life years (QALY), and incremental cost-effectiveness ratio (ICER) over 10 years for patients with ES-
          SCLC  treated  with  benmelstobart  plus  anlotinib  and  chemotherapy,  or  chemotherapy  alone.  One-way  sensitivity  analysis  and
          probability  sensitivity  analysis  were  performed  to  verify  the  robustness  of  the  simulation  results.  The  willingness-to-pay (WTP)
          threshold was set at 3 times the per capita gross domestic product (GDP) of China in 2023, which amounted to 268 074 yuan/QALY.
          RESULTS  Compared  with  chemotherapy  alone,  benmelstobart  combined  with  anlotinib  and  chemotherapy  gained  0.438  QALY
          more at the cost of 403 505.55 yuan more, with an ICER of 922 031.37 yuan/QALY, which was higher than the WTP threshold set
          in  this  study.  One-way  sensitivity  analysis  showed  that  benmelstobart’s  cost  and  utility  value  of  the  progression-free  survival  state
          had  a  greater  impact  on  the  ICER  value;  probabilistic  sensitivity  analysis  confirmed  the  robustness  of  the  model;  only  when  the
          price  of  benmelstobart  was  reduced  by  75.4%,  the  combined  regimen  would  be  cost-effective.  CONCLUSIONS  The  first-line
          treatment  of  ES-SCLC  with  benmelstobart  combined  with  anlotinib  and  chemotherapy  is  not  cost-effective  from  the  perspective  of
          China’s healthcare system at present.
