          摘  要  目的  从中国卫生体系的角度,评估不同序贯治疗方案治疗人表皮生长因子受体2(HER-2)阳性晚期胃癌的经济性。方法
          从ToGA、WJOG 4007和RAINBOW-Asia试验中获取生存数据,采用网状Meta分析进行调整。构建四状态Markov模型评估6种
          治疗序列的经济性,模拟时限为终身,循环周期为4周(28 d),模型的主要输出参数包括总成本、质量调整生命年(QALY)和增量
          成本-效果比(ICER)。通过敏感性分析检验基础分析结果的稳健性,并对曲妥珠单抗进行降价情境分析。结果  相比化疗序贯紫
          杉醇,曲妥珠单抗联合化疗序贯紫杉醇或伊立替康或雷莫西尤单抗联合紫杉醇的ICER分别为349 845.25、772 410.64、2 510 470.39
          元/QALY,均超过3倍我国2023年人均国内生产总值(GDP)作为的意愿支付(WTP)阈值(268 074元/QALY),显示化疗序贯紫杉
          醇方案为最优治疗方案。敏感性分析结果证明了基础分析结果的稳健性。情境分析结果表明,当曲妥珠单抗降价幅度大于20%
          时,在本研究的WTP阈值下,曲妥珠单抗联合化疗序贯紫杉醇方案开始具有经济性。结论  在以3倍我国2023年人均GDP作为
          WTP阈值时,化疗序贯紫杉醇是治疗HER-2阳性晚期胃癌的最优方案,曲妥珠单抗联合化疗序贯紫杉醇为次优方案。随着医保
          政策优化力度的增大,曲妥珠单抗联合化疗序贯紫杉醇有望成为最具经济性的治疗方案。

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-effectiveness  of  different  sequential  treatment  regimens  for  human  epidermal
          growth factor receptor 2 (HER-2)-positive advanced gastric cancer from the perspective of the Chinese health system. METHODS
          Survival data were obtained from the ToGA, WJOG 4007 and RAINBOW-Asia trials, and adjusted using network meta-analysis. A
          four-state  Markov  model  was  constructed  to  evaluate  the  cost-effectiveness  of  six  treatment  sequences,  with  a  lifetime  simulation
          horizon and a cycle period of 4 weeks (28 d), and the main output parameters of the model included total costs, quality-adjusted
          life year (QALY), and incremental cost-effectiveness ratio (ICER). Sensitivity analysis was conducted to test the robustness of the
          basic  analysis  results,  and  a  price  reduction  scenario  analysis  for  trastuzumab  was  performed.  RESULTS  Compared  with
          chemotherapy  sequentially  treated  with  paclitaxel,  the  ICER  of  trastuzumab  combined  with  chemotherapy  sequentially  treated  with
          paclitaxel,  or  irinotecan,  or  ramucirumab  plus  paclitaxel  were  349  845.25,  772  410.64,  and  2  510  470.39  yuan/QALY,
          respectively,  all  exceeding  three  times  China’s  2023  per  capita  gross  domestic  product (GDP) (268  074  yuan/QALY)  as  the
          willingness-to-pay (WTP) threshold. This indicated that chemotherapy sequential paclitaxel was the optimal treatment regimen. The
          sensitivity analysis confirmed the robustness of the basic analysis. The scenario analysis showed that when trastuzumab was reduced
          by  more  than  20%,  trastuzumab  combined  with  chemotherapy  sequentially  treated  with  paclitaxel  became  cost-effective  under  this
          study’s  WTP  threshold.  CONCLUSIONS  When  using  three  times  China’s  2023  per  capita  GDP  as  the  WTP  threshold,
          chemotherapy  sequentially  treated  with  paclitaxel  is  the  optimal  regimen  for  HER-2  positive  advanced  gastric  cancer,  with
          trastuzumab  combined  with  chemotherapy  sequentially  treated  with  paclitaxel  as  the  second  best  option.  With  enhanced  medical
          insurance  optimization,  trastuzumab  combined  with  chemotherapy  sequentially  treated  with  paclitaxel  is  expected  to  become  the
          most cost-effective treatment regimen.
