An integrated magnetic resonance scanner and linear accelerator (MR-linac) was implemented with daily online adaptive radiation therapy (ART). This study evaluated patient-reported experiences with their overall hospital care as well as treatment in the MR-linac environment.
Patients pre-screened for MR eligibility and claustrophobia were referred to simulation on a 1.5 T MR-linac. Patient-reported experience measures were captured using two validated surveys. The 15-item MR-anxiety questionnaire (MR-AQ) was administered immediately after the first treatment to rate MR-related anxiety and relaxation. The 40-item satisfaction with cancer care questionnaire rating doctors, radiation therapists, the services and care organization and their outpatient experience was administered immediately after the last treatment using five-point Likert responses. Results were analyzed using descriptive statistics.
205 patients were included in this analysis. Multiple sites were treated across the pelvis and abdomen with a median treatment time per fraction of 46 and 66 min respectively. Patients rated MR-related anxiety as "not at all" (87%), "somewhat" (11%), "moderately" (1%) and "very much so" (1%). Positive satisfaction responses ranged from 78 to 100% (median 93%) across all items. All radiation therapist-specific items were rated positively as 96-100%. The five lowest rated items (range 78-85%) were related to general provision of information, coordination, and communication. Overall hospital care was rated positively at 99%.
In this large, single-institution prospective cohort, all patients had low MR-related anxiety and completed treatment as planned despite lengthy ART treatments with the MR-linac. Patients overall were highly satisfied with their cancer care involving ART using an MR-linac.
将集成磁共振扫描仪和直线加速器（MR-直线加速器）应用于每日在线自适应放射治疗（ART）。本研究评估了患者对其整体医院护理以及在MR-直线加速器环境中治疗的报告体验。
对经磁共振成像（MR）资格和幽闭恐惧症预筛查的患者，在1.5T MR-直线加速器上进行模拟。使用两项经过验证的调查收集患者报告的体验指标。15项MR焦虑问卷（MR-AQ）在首次治疗后立即进行，以评估与MR相关的焦虑和放松程度。40项癌症护理满意度问卷对医生、放射治疗师、服务和护理组织以及他们的门诊体验进行评分，并在最后一次治疗后立即使用五点李克特量表进行回答。结果采用描述性统计分析。
本分析纳入了205名患者。骨盆和腹部的多个部位接受了治疗，每次分割的中位治疗时间分别为46分钟和66分钟。患者将与MR相关的焦虑评为“完全没有”（87%）、“有点”（11%）、“中度”（1%）和“非常严重”（1%）。所有项目的积极满意度回答范围为78%至100%（中位数为93%）。所有与放射治疗师相关的项目的好评率为96%至100%。评分最低的五个项目（范围为78%至85%）与信息的一般提供、协调和沟通有关。整体医院护理的好评率为99%。
在这个大型单机构前瞻性队列中，所有患者与MR相关的焦虑较低，尽管使用MR-直线加速器进行了长时间的ART治疗，但仍按计划完成了治疗。总体而言，患者对使用MR-直线加速器的ART癌症护理非常满意。
