摘要

在这项研究中,我们旨在对日本已安装商用在线自适应放射治疗系统(oART)的机构目前的临床实践、人员配备、调试和人员培训情况进行调查,并与今后将安装 oART 系统的机构分享相关信息。我们向日本的九家机构发放了一份包含 107 个问题的网络问卷。数据收集时间为 2023 年 11 月至 12 月。使用 MRIdian(ViewRay,Oakwood Village,OH,USA)、Unity(Elekta AB,Stockholm,Sweden)和 Ethos(Varian Medical Systems,Palo Alto,CA,USA)系统的各三家机构完成了问卷调查。有一家机构(MRIdian)在问卷截止日期前尚未执行 oART。每家机构只安装了一套 oART 系统。MRIdian/Unity和Ethos系统分别采用了低分切术、中度低分切术或常规分切术。与其他系统相比,Ethos 系统的 oART 过程耗时更短。所有机构都为 oART 增加了额外的工作人员。由于供应商提供的光束数据不同,各 oART 系统的调试时间也不同。各机构在试运行测量期间使用的腔室也不尽相同。所有九个机构都提供了机构培训。据我们所知,这是日本首次对使用商业系统进行的 oART 进行调查。我们相信,这项研究将为已安装、正在安装或计划安装 oART 系统的机构提供有用的信息。

Multi-institutional questionnaire-based survey on online adaptive radiotherapy performed using commercial systems in Japan in 2023.

In this study, we aimed to conduct a survey on the current clinical practice of, staffing for, commissioning of, and staff training for online adaptive radiotherapy (oART) in the institutions that installed commercial oART systems in Japan, and to share the information with institutions that will implement oART systems in future. A web-based questionnaire, containing 107 questions, was distributed to nine institutions in Japan. Data were collected from November to December 2023. Three institutions each with the MRIdian (ViewRay, Oakwood Village, OH, USA), Unity (Elekta AB, Stockholm, Sweden), and Ethos (Varian Medical Systems, Palo Alto, CA, USA) systems completed the questionnaire. One institution (MRIdian) had not performed oART by the response deadline. Each institution had installed only one oART system. Hypofractionation, and moderate hypofractionation or conventional fractionation were employed in the MRIdian/Unity and Ethos systems, respectively. The elapsed time for the oART process was faster with the Ethos than with the other systems. All institutions added additional staff for oART. Commissioning periods differed among the oART systems owing to provision of beam data from the vendors. Chambers used during commissioning measurements differed among the institutions. Institutional training was provided by all nine institutions. To the best of our knowledge, this was the first survey about oART performed using commercial systems in Japan. We believe that this study will provide useful information to institutions that installed, are installing, or are planning to install oART systems.
