          摘   要  目的  评价派安普利单抗联合化疗方案一线治疗晚期鳞状非小细胞肺癌(以下简称“肺鳞癌”)的经济性。方法  从我国卫
          生体系角度出发,运用成本-效用分析法评估派安普利单抗联合化疗(紫杉醇+卡铂)方案相较于标准化疗(紫杉醇+卡铂)方案一线
          治疗晚期肺鳞癌的经济性。使用R语言构建一个三健康状态Markov模型,模型中所需的临床数据提取自AK105-302研究,成本
          和效用来自开放数据库和已发表的文献。效用指标为质量调整生命年(QALY),意愿支付(WTP)阈值为2024年我国人均国内生
          产总值(GDP)的 3 倍,即 287 247 元/QALY。通过比较两种方案的增量成本-效果比(ICER)与 WTP 阈值的大小评估方案的经济
          性;使用单因素敏感性分析和概率敏感性分析验证基础分析的稳健性。结果  派安普利单抗联合化疗方案较标准化疗方案增加了
          0.73 QALY,但同时成本增加150 681.93元,ICER为206 413.60元/QALY。单因素敏感性分析显示,无进展生存(PFS)状态的效用
          值对ICER的影响最大。概率敏感性分析显示,WTP阈值为3倍的2024年我国人均GDP时,派安普利单抗联合化疗方案具有经济
          性的概率为98.80%;但当WTP阈值降低为1倍我国人均GDP时,派安普利单抗联合化疗方案具有经济性的概率<0.01%。结论
          对于晚期肺鳞癌,当WTP阈值为3倍的2024年我国人均GDP时,派安普利单抗联合化疗是一种具有经济性的一线治疗方案。

          ABSTRACT    OBJECTIVE  To  estimate  the  cost-effectiveness  of  penpulimab  combined  with  chemotherapy  versus  chemotherapy
          alone  in  first-line  treatment  of  advanced  squamous  non-small-cell  lung  cancer (sq-NSCLC).  METHODS  From  the  perspective  of
          Chinese health system, cost-utility analysis was used to evaluate the cost-effectiveness of penpulimab combined with chemotherapy
         (paclitaxel + carboplatin) versus chemotherapy (paclitaxel + carboplatin) in first-line treatment of sq-NSCLC. A three-health states
          Markov  model  was  constructed  with  R  packages,  and  clinical  data  used  in  the  model  were  derived  from  the AK105-302  clinical
          trial.  Costs  and  utilities  were  collected  from  the  open-access  database  and  published  literature.  The  quality-adjusted  life-years
         (QALY) was used as the utility index, and the willingness-to-pay (WTP) threshold was set at three times China’s per capita GDP
          in 2024, equivalent to 287 247 yuan/QALY. The cost-effectiveness of the schemes was evaluated by comparing the incremental cost-
          utility ratios (ICER) of the two schemes with the WTP threshold. One-way sensitivity analysis and probabilistic sensitivity analysis
                                                             (PSA)  were  used  to  verify  the  stability  of  the  basic  analysis
