          摘  要  目的  从中国卫生体系的角度出发,评估不可切除的恶性间皮瘤患者经一线化疗后,转换吉西他滨维持治疗的经济性。
          方法  根据NVALT19试验数据构建分区生存模型,循环周期为21 d,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)等。采用成本-效用分析法评价不可切除的恶性间皮瘤患者
          经一线化疗后转换吉西他滨维持治疗(吉西他滨组)方案相对于采用最佳支持治疗(支持治疗组)方案的经济性,并进行敏感性分
          析。结果  与支持治疗组方案相比,吉西他滨组方案的ICER为54 860.50元/QALY,远小于以3倍2023年我国人均国内生产总值
          作为的意愿支付阈值(268 077元/QALY),说明吉西他滨组方案具有经济性。单因素敏感性分析结果显示,临终关怀成本和吉西
          他滨组不良事件处理成本对ICER的影响较大;概率敏感性分析结果表明,当意愿支付阈值大于270 000元/QALY时,吉西他滨组
          方案具有经济性的概率为100%。结论  从中国卫生体系的角度出发,不可切除的恶性间皮瘤在一线化疗后转换吉西他滨维持治
          疗的方案具有经济性。

          Cost-utility  analysis  of  switching  to  gemcitabine  maintenance  therapy  for  malignant  mesothelioma  patients
          after first-line chemotherapy

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-utility  of  switching  to  gemcitabine  maintenance  therapy  for  patients  with
          unresectable  malignant  mesothelioma  after  first-line  chemotherapy  from  the  perspective  of  China’s  healthcare  system.  METHODS
          A  partitioned  survival  model  was  constructed  based  on  data  from  the  NVALT19  trial,  with  a  cycle  length  of  21  days,  a  time
          horizon  of  10  years,  and  a  discount  rate  of  5%.  Key  model  outputs  included  total  costs,  quality-adjusted  life  year (QALY),
          incremental  costs,  and  incremental  cost-effectiveness  ratio (ICER),  etc.  Cost-utility  analysis  was  conducted  to  evaluate  the  cost-
          effectiveness  of  gemcitabine  maintenance  therapy (gemcitabine  group)  plan  versus  best  supportive  care (supportive  care  group)
          plan  for  the  patients  with  unresectable  malignant  mesothelioma  after  first-line  chemotherapy.  Sensitivity  analyses  were  performed.
          RESULTS  Compared  with  the  supportive  care  group  plan,  the  gemcitabine  group  plan  had  an  ICER  of  54  860.50  yuan/QALY,
          which  was  significantly  lower  than  the  willingness-to-pay (WTP)  threshold (3  times  China’s  2023  per  capita  gross  domestic
          product,  268  077  yuan/QALY),  indicating  that  gemcitabine  group  plan  was  cost-effective.  One-way  sensitivity  analysis  revealed
          that  end-of-life  care  costs  and  adverse  event  management  costs  in  the  gemcitabine  group  had  the  greatest  impact  on  ICER.
          Probabilistic sensitivity analysis showed gemcitabine group plan was 100% cost-effective when WTP exceeded 270 000 yuan/QALY.
          CONCLUSIONS From the perspective of China’s healthcare system, switching to gemcitabine maintenance therapy after first-line
          chemotherapy is cost-effective for unresectable malignant mesothelioma.
