          摘   要  目的  从我国卫生体系角度出发评价斯鲁利单抗联合化疗方案一线治疗广泛期小细胞肺癌(ES-SCLC)的经济性。方法  基
          于ASTRUM-005研究和相关文献数据构建分区生存模型,模型模拟时限为10年,循环周期为3周,成本和效用值均采用5%的贴
          现率进行贴现。以质量调整生命年(QALY)作为模型产出指标并计算增量成本-效果比(ICER),评价斯鲁利单抗联合化疗方案
         (斯鲁利单抗组)对比单纯化疗方案(单纯化疗组)一线治疗ES-SCLC的经济性。采用单因素敏感性分析和概率敏感性分析验证
          基础分析结果的稳健性,并针对斯鲁利单抗援助计划进行情境分析。结果  基础分析结果显示,斯鲁利单抗组相对于单纯化疗组
          的ICER为758 690.27元/QALY,高于以3倍2022年我国人均国内生产总值(GDP)作为的意愿支付(WTP)阈值。情境分析结果显
          示,斯鲁利单抗组相对于单纯化疗组的ICER为172 275.74元/QALY,低于上述WTP阈值。单因素敏感性分析结果显示,无进展生
          存状态效用值、斯鲁利单抗价格等对模型结果影响较大。概率敏感性分析结果显示,不考虑斯鲁利单抗援助计划时,斯鲁利单抗
          组具有经济性的概率为0;但考虑援助计划时,斯鲁利单抗组具有经济性的概率为100%。结论  在以3倍2022年我国人均GDP为
          WTP阈值时,斯鲁利单抗组相对于单纯化疗组不具有经济性;但若将援助计划考虑在内,该结果将发生翻转。

          ABSTRACT    OBJECTIVE  To  evaluate  the  economics  of  serplulimab  combined  with  chemotherapy  regimens  for  the  first-line
          treatment  of  extensive-stage  small  cell  lung  cancer (ES-SCLC)  from  the  perspective  of  health  system  in  China.  METHODS  A
          partitioned  survival  model  was  constructed  based  on  the  ASTRUM-005  clinical  trial  and  related  literature  data,  with  a  model
          simulation  time  frame  of  10  years  and  a  3-week  cycle,  and  both  cost  and  utility  values  were  discounted  using  a  5%  discount  rate.
          The  quality-adjusted  life  year (QALY)  was  used  as  a  model  output  indicator  and  the  incremental  cost-effectiveness  ratio (ICER)
          was  calculated  to  evaluate  the  economics  of  serplulimab  combined  with  chemotherapy  regimens (serplulimab  group)  versus
          chemotherapy alone regimens (chemotherapy alone group) for the first-line treatment of ES-SCLC. One-way sensitivity analysis and
          probabilistic sensitivity analysis were used to verify the robustness of the results of the base-case analysis and to conduct a scenario
          analysis for the serplulimab patient assistance program. RESULTS The results of the base-case analysis showed that compared with
          chemotherapy  alone  group,  ICER  of  serplulimab  group  was  758  690.27  yuan/QALY,  which  was  higher  than  3  times  China’s  per
          capita  gross  domestic  product (GDP)  in  2022  as  the  willingness-to-pay (WTP)  threshold.  The  results  of  the  scenario  analysis
          showed  that  compared  with  chemotherapy  alone  group,  the  ICER  of  serplulimab  group  was  172  275.74  yuan/QALY,  which  was
                                                              below  above  WTP  threshold.  The  one-way  sensitivity  analysis
