        摘   要   目的:为我国抗肿瘤药物经济学评价的模型选择、以及我国肿瘤药物药物经济学评价证据质量的提升提供参考。方法:
        在加拿大药品与卫生技术局(CADTH)官网对抗肿瘤药物卫生技术评估(pCODR)报告进行系统检索,报告时间限定为2015年1
        月1日-2020年9月6日,对其基本信息、模型类型及结构、模型中存在的关键问题等进行提取与总结。结果与结论:共检索获得
        185份pCODR报告,涉及114种肿瘤适应证和98种抗肿瘤药物。近5年CADTH抗肿瘤药物经济学评价数量呈递增趋势。在137
        份附有最终经济性指导报告的pCODR报告中,98份报告(占71.5%)使用了分区生存模型进行评估,21份报告(占15.3%)使用了
        状态转移模型,还有部分报告(6份,4.3%)同时使用了分区生存模型和状态转移两种模型以探讨模型结构的不确定性。在模型健
        康状态设定方面,86份报告(占62.8%)使用了三状态模型以评估不同抗肿瘤药物的经济性,还有16份报告(占11.7%)使用了不
        少于4种健康状态来模拟疾病的状态转归。但CADTH模型中尚存在研究时限选择不合理、疗效(生存)数据外推方法不合理或外
        推结果不确定、通过间接比较获取的疗效数据不确定以及部分假设或参数设置不符合实际诊疗环境等问题。鉴于分区生存模型
        的诸多优势,建议我国未来抗肿瘤药物经济学评价优先考虑使用分区生存模型或联合使用马尔可夫模型与分区生存模型来验证
        模型结构的不确定性,并合理设置重点模型参数,以提升我国抗肿瘤药物经济学评价的证据质量。

        ABSTRACT    OBJECTIVE:To provide reference for selecting antitumor drugs economic evaluation models and improving the
        quality of evidence for antitumor drugs economics evaluation in China. METHODS:A systematic search of the antitumor drug
        health technology evaluation (pCODR) reports were conducted on the official website of the Canadian Agency for Drugs and
        Technologies in Health(CADTH). The search time was limited to Jan. 1st,2015 to Sep. 6th,2020. The basic information,model
        types and structure,and key limitations were extracted and summarized. RESULTS & CONCLUSIONS:A total of 185 pCODR
        reports were finally retrieved,involving 114 types of tumor indications and 98 types of antitumor drugs. The number of CADTH
        antitumor drugs economics evaluations in the past 5 years had shown an increasing trend. Among 137 pCODR reports with final
        economic guidance report,98 reports(71.5%)adopted the PartSA model,21 reports(15.3%)used the Markov model,and some
        reports(6 reports,4.3%)used both PartSA and Markov models to explore the uncertainty of the model structure. In terms of
        model health status setting,86 reports(62.8%)used three-state models to evaluate the economy of different antitumor drugs,and
        16 reports(11.7%)used no less than four health states to simulate the outcome of disease state. However,there were still some
        problems in CADTH models,such as the unreasonable choice of research time limit,the unreasonable extrapolation method or
        uncertain extrapolation results of efficacy(survival)data,the uncertainty of efficacy data obtained by indirect comparison,and
        some assumptions or parameter settings did not conform to the actual diagnosis and treatment environment. In view of the
        advantages of PartSA model,it is suggested that PartSA model or Markov model combined with PartSA model should be used first
        to verify the uncertainty of model structure in the future economic evaluation of antitumor drugs;reasonable settings of key model
                                                            parameters should be considered to improve the quality of
