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。

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.
