        码基因突变阳性的局部晚期或转移性非小细胞肺癌(NSCLC)的经济性,为我国医疗卫生决策提供循证依据。方法:从卫生体系
        角度出发,利用 FLAURA 研究中的患者生存数据和已发表的文献数据建立马尔科夫模型,模拟 EGFR 突变阳性的局部晚期
        NSCLC患者10年的直接医疗成本和质量调整生命年(QALY),模型循环周期为3周,贴现率为5%。采用单因素敏感性分析和概
        率敏感性分析评价参数变化对模型结果稳定性的影响。结果:基础分析中,奥希替尼对比第1代EGFR-TKIs可多获得0.40 QALYs,
        增量成本为163 531.55元,增量成本-效用比(ICER)为409 321.54元/QALY,高于我国的意愿支付阈值[2019年我国3倍人均国内
        生产总值(GDP)212 676元/QALY]。单因素敏感性分析结果显示,无进展生存状态的效用值和奥希替尼的价格对ICER值影响最
        大。概率敏感性分析结果显示,在我国现有的意愿支付阈值下,奥希替尼具有经济性的概率为 11.00%;当奥希替尼分别降价
        30%、50%、70%时,其在意愿支付阈值为212 676元/QALY时具有经济性的概率分别为26.20%、47.40%、74.30%。结论:当采用
        2019 年我国 3 倍人均 GDP 作为判断标准时,奥希替尼对比第 1 代 EGFR-TKIs 一线治疗 EGFR 突变阳性的局部晚期或转移性
        NSCLC不具有经济性;适当的降价可提高其经济性。

        ABSTRACT    OBJECTIVE:To evaluate the economics of osimertinib versus first-generation EGFR-TKIs in the first-line treatment
        of EGFR mutation-positive locally advanced or metastatic non-small cell lung cancer(NSCLC),and to provide evidence-based
        reference for medical and healthy decision-making in China. METHODS:From respective of health care system,Markov model
        was developed by using patientsurvival data and published literature datato simulate 10 years of direct medical costs and
        quality-adjusted life years(QALY)for EGFR mutation-positive locally advanced or metastatic NSCLC patients,with a model cycle
        length of 3 weeks,and the discount rate of 5%. One-way sensitivity analysis and probabilistic sensitivity analysis were used to
        evaluate the effects of parameter changes on the stability of the model results. RESULTS:In the base-case analysis,compared with
        the first-generation EGFR-TKIs,osimertinib could obtain 0.40 QALYs more,with an incremental cost of 163 531.55 yuan and an
        incremental cost-utility ratio(ICER)of 409 321.54 yuan/QALY,which was higher than the willingness-to-pay(WTP)threshold in
        China(3 times per capita GDP in China in 2019 of 212 676 yuan/QALY). The results of one-way sensitivity analysis showed that
        the utility value of progression-free survival status and the price of osimertinib had the greatest impact on ICER. The results of
        probability sensitivity analysis showed that the probability of osimertinib to be cost-effective was 11.00% at the WTP threshold in
        China. When the price of osimertinib decreased by 30%,50% and 70%,the probability of osimertinib to be cost-effective was
        26.20%,47.40%,and 74.30% at the WTP threshold of 212 676 yuan/QALY,respectively. CONCLUSIONS:When Chinese 3
        times per capita GDP in 2019 is used as the criterion for judgment, osimertinib is not economical compared with the
                                                            first-generation EGFR-TKIs in first-line treatment of locally
