摘 要 目的 从我国卫生体系角度出发,评估芦康沙妥珠单抗(ST)对比医生选择的化疗方案(TPC)用于转移性三阴性乳腺癌
(mTNBC)二线及后线治疗的经济性。方法 基于OptiTROP-Breast01研究,根据mTNBC疾病发展过程构建分区生存模型,设置循
环周期为4周,模拟时限为10年,贴现率为5%。以质量调整生命年(QALY)和总成本作为产出指标,计算ST方案相对于TPC用
于mTNBC二线及后线治疗的增量成本-效果比(ICER),利用敏感性分析验证基础分析结果的稳健性。结果 在以3倍我国2024
年人均国内生产总值(GDP)为意愿支付阈值(287 247元/QALY)的前提下,使用ST方案的患者在获得增量效用(0.42 QALY)的同
时也需要支付更多成本,ICER为205 562.07元/QALY,低于意愿支付阈值,表明ST方案相对于TPC更具经济性。单因素敏感性分
析结果显示,无进展生存期状态健康效用值和ST成本对ICER值影响较大。概率敏感性分析和情况分析结果表明基础分析结果
稳健。结论 从我国卫生体系角度出发,以3倍我国人均GDP为意愿支付阈值,ST方案相对于TPC用于我国mTNBC患者二线及
以后线治疗更具经济性。

ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of sacituzumab tirumotecan (ST) versus chemotherapy treatment
physician’s choice (TPC) as second-line and later-line treatment for metastatic triple-negative breast cancer (mTNBC) from the
perspective of China’s healthcare system. METHODS A partitioned survival model was constructed based on the OptiTROP-Breast 01
trial, with a cycle length of 4 weeks and a time horizon of 10 years, applying a 5% discount rate. Quality adjusted life year
(QALY) and costs were used as outcome measures, and the incremental cost-effectiveness ratio (ICER) of ST versus TPC for
second-line and later-line treatment of mTNBC was calculated. Sensitivity analyses were conducted to validate the robustness of the
base-case results. RESULTS At a willingness-to-pay threshold (WTP) of 3 times China’s 2024 per capita gross domestic product
(GDP) (287 247 yuan/QALY), patients receiving ST gained incremental utility (0.42 QALY) at a higher cost, yielding an ICER
of 205 562.07 yuan/QALY, which was lower than WTP, indicating that ST was more cost-effective compared to TPC. One-way
sensitivity analysis revealed that key factors influencing the ICER included the utility value of progression-free survival and the
price of ST. Probabilistic sensitivity analysis and scenario analysis showed that the base-case results were robust. CONCLUSIONS
From the perspective of China’s healthcare system, at a WTP of 3 times China’s per capita GDP, ST is more cost-effective than
TPC as second-line and later-line treatment for mTNBC.
