ARCH PATHOL LAB MED:肺腺癌分子检测策略---成本分析的更佳方法

2019-05-09 不详 网络

肺腺癌治疗重要基因的分子分析是临床实践的标准,目前,多个专业组织建议检测所有腺癌的EGFR、ALK和ROS1突变。一些组织建议​​与专家组联合分析这些基因。从成本角度来看,目前关于最优测试方法或最优测试序列的数据很少。因此,本研究的目的是确定基因测试中哪个顺序、组合或下一代测序(NGS)成本最低。

肺腺癌治疗重要基因的分子分析是临床实践的标准,目前,多个专业组织建议检测所有腺癌的EGFRALKROS1突变。一些组织建议​​与专家组联合分析这些基因。从成本角度来看,目前关于最优测试方法或最优测试序列的数据很少。因此,本研究的目的是确定基因测试中哪个顺序、组合或下一代测序(NGS)成本最低。

研究团队最近的建议提出了一套基本的分子测试(EGFRALKROS1)和一套可选的分子测试,这些测试可能对临床试验的选择有用。研究人员比较了3个必需基因和5个最优基因的不同测试测序策略的成本。测试成本是通过对大型实验室的价格调查确定的。被评为成本最低的策略被指定为最优测试策略。

从成本的角度来看,按EGFR-ROS1-ALK顺序对必需基因进行序列检测是最优的。序列测试的预期成本为2227美元(95% CI, 1733 - 2794美元)NGS的成本是2500美元。使用这种策略,每个阳性结果的预期成本为11,362美元。

研究表明,肺腺癌的3个基本基因和5个可选基因的分子检测可通过多种方法和多种序列进行。从成本的角度来看,EGFRROS1ALK顺序的顺序测试是最优的。如果价格低于2200美元,NGS将具有竞争力。如果对3个基本基因进行测试后,接着对5个可选基因进行测试,则NGS是最优的。如果临床医生计划同时测试必要基因和可选基因,NGS测试是最佳的。
