          摘   要  目的  从中国卫生体系角度出发,评估舒格利单抗联合化疗方案(以下简称“联合方案”)一线治疗程序性死亡受体配体1
         (PD-L1)高表达晚期食管鳞状细胞癌(ESCC)的经济性。方法  根据GEMSTONE-304研究的数据构建分期生存模型,模型周期为
          3周,研究时限为10年,贴现率为5%。模型的主要输出参数包括总成本、质量调整生命年(QALY)、增量成本和增量成本-效果比
         (ICER)。采用成本-效用分析法评价联合方案相对于单用化疗方案的经济性,并通过单因素敏感性分析、概率敏感性分析和情境
          分析来评估基础分析结果的稳健性。结果  联合方案相比于单用化疗方案的ICER为288 430.35元/QALY,远高于以1.94倍2023
          年中国人均国内生产总值(GDP)作为的意愿支付(WTP)阈值(173 354.52元/QALY)。舒格利单抗的成本是影响ICER的主要因
          素。当WTP阈值为1.94倍2023年中国人均GDP(173 354.52元/QALY)时,联合方案相比于单用化疗方案具有经济性的概率为0;
          当该药价格下降至6 107.41元/盒(600 mg)后,联合方案相比于单用化疗方案才会体现出经济性。结论  从中国卫生体系角度出
          发,联合方案一线治疗PD-L1高表达晚期ESCC患者不具有经济性;当其价格降低50.65%,才具有经济性。

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  the  first-line  treatment  using  the  combination  therapy  of
          sugemalimab  and  chemotherapy (hereinafter  referred  to  as  the “combination  therapy”)  for  advanced  esophageal  squamous  cell
          carcinoma (ESCC)  with  high  programmed  death-ligand  1 (PD-L1)  expression  from  the  perspective  of  the  Chinese  healthcare
          system. METHODS A partitioned survival model was constructed based on data from the GEMSTONE-304 study. The model cycle
          was  set  at  3  weeks,  with  a  study  duration  of  10  years  and  a  discount  rate  of  5%.  The  primary  output  parameters  of  the  model
          included total costs,  quality-adjusted life year (QALY),  incremental costs,  and incremental cost-effectiveness ratio (ICER).  Cost-
          utility  analysis  was  employed  to  assess  the  economic  feasibility  of  the  combination  therapy  compared  to  chemotherapy  alone.  The
          robustness  of  the  base  case  analysis  results  was  evaluated  through  univariate  sensitivity  analysis,  probabilistic  sensitivity  analysis,
          and  scenario  analysis.  RESULTS  The  ICER  of  the  combination  therapy  compared  to  chemotherapy  alone  was  288  430.35
          yuan/QALY,  significantly  exceeding  the  willingness-to-pay (WTP)  threshold  of  173  354.52  yuan/QALY  which  was  set  at  1.94
