        本-效果比(ICER)为 1 467 546.54 元/QALY,远高于 3 倍 2020 年我国人均国内生产总值(GDP,即 217 713 元)作为的意愿支付
        (WTP)阈值。单因素敏感性分析结果显示,度伐利尤单抗价格和贴现率对 ICER 值的影响较大。概率敏感性分析结果显示,当
        WTP阈值为3倍2020年我国人均GDP(217 713元)时,度伐利尤单抗具有经济性的概率为0。结论 从我国卫生体系角度出发,当
        WTP阈值为3倍2020年我国人均GDP时,度伐利尤单抗用于不可手术切除、Ⅲ期非小细胞肺癌放化疗后巩固治疗不具有经济性。

        ABSTRACT    OBJECTIVE To evaluate the cost-effectiveness of durvalumab for consolidation therapy after chemoradiotherapy
        for unresectable stage Ⅲ non-small cell lung cancer from the perspective of the Chinese health care system. METHODS A Markov
        model was developed by using updated four-year survival data from the PACIFIC trial in May 2021 and relevant literature. The
        cost-effectiveness of durvalumab for consolidation therapy after chemoradiotherapy for unresectable stage Ⅲ non-small cell lung
        cancer was evaluated by using quality-adjusted life years(QALYs)as health output index with 20-year simulation time frame and a
        2-week cycling period. The costs and health output were discounted using discount rate of 5%;one-way sensitivity analysis and
        probabilistic sensitivity analysis were used to examine the robustness of the model simulation results. RESULTS The results of the
        base analysis showed that compared with placebo group,durvalumab resulted in 0.73 QALYs at an incremental cost of 1 076
        062.86 yuan and an incremental cost-utility ratio(ICER)of 1 467 546.54 yuan/QALY,which was much higher than 3-fold per
        capita gross domestic products(GDP)in 2020(217 713 yuan)as willingness-to-pay(WTP)threshold. The results of one-way
        sensitivity analysis showed that the price of durvalumab and discount rate had a great impact on ICER. Probabilistic sensitivity
        analysis showed no cost-effective advantage for durvalumab when the WTP threshold was three times of GDP per capita in 2020
        (217 713 yuan). CONCLUSIONS From the perspective of Chinese health care system,there is no cost-effective advantage to the
        use of durvalumab for consolidation therapy after chemoradiotherapy for unresectable stage Ⅲ non-small cell lung cancer when the
        WTP threshold was three times of GDP per capita in 2020.
