摘 要 目的 评价帕妥珠单抗联合曲妥珠单抗、多西他赛(PTD)方案相比曲妥珠单抗联合多西他赛(TD)方案一线治疗人表皮生
长因子受体2(HER2)阳性转移性乳腺癌的经济性。方法 从我国卫生体系角度出发,利用CLEOPATRA临床试验披露的生存数据
和相关文献数据构建分区生存模型,模型模拟时限设为20年,循环周期为3周,贴现率为5%。模型的产出指标包括两种治疗方
案的成本及质量调整生命年(QALYs)。意愿支付(WTP)阈值设为 2020 年我国 1~3 倍人均国内生产总值(GDP),即 72 000~
216 000元/QALY。采用单因素敏感性分析及概率敏感性分析评价模型参数变化对结果稳健性的影响。结果 基础分析结果显示,
在20年的模拟时限内,PTD方案较TD方案可带来更高的健康获益(3.28 QALYs vs. 2.50 QALYs),但总成本更高(1 219 376.83元
vs. 784 007.84元);与TD方案相比,PTD方案的增量成本-效果比为554 625.46元/QALY,超过WTP阈值。单因素敏感性分析结果
显示,疾病无进展生存状态的效用值对结果的影响最大。概率敏感性分析结果显示,使用我国2020年3倍人均GDP作为WTP阈
值时,PTD方案具有经济性的概率为1%;当WTP阈值升至550 000元/QALY时,PTD方案具有经济性的概率可达50%。结论 与
TD方案相比,PTD方案一线治疗HER2阳性转移性乳腺癌不具有经济性。

ABETRACT OBJECTIVE To evaluate the economics of pertuzumab combined with trastuzumab and docetaxel(PTD)regimen
versus trastuzumab combined with docetaxel (TD) regimen in first-line treatment of human epidermal growth factor receptor 2
(HER2)-positive metastatic breast cancer. METHODS From the perspective of Chinese healthcare system,the partitioned survival
model was constructed by using survival data disclosed in the CLEOPATRA clinical trial and relevant literature data. The time
horizon of the model was set as 20 years and the cycle length of the model was 3 weeks,and discount rate was 5%. The output
indicators of the model included the cost and quality-adjusted life years(QALYs)of the two treatment regimens. The threshold of
willingness-to-pay(WTP)was set as 1-3 times per capita gross domestic product(GDP)in China in 2020,i. e. 72 000-216 000
yuan/QALY. One-way sensitivity analysis and probabilistic sensitivity analysis were used to evaluate the influence of model
parameter changes on the robustness of the results. RESULTS The results of base-case analysis showed that within the horizon of
20 years,PTD regimen could bring more health benefit than TD regimen(3.28 QALYs vs. 2.50 QALYs),but the total costs was
higher(1 219 376.83 yuan vs. 784 007.84 yuan). Compared
