本研究的目的是调查日本宫颈癌3D图像引导近距离放射治疗（3D-IGBT）的当前实践模式和实施障碍。2012年，向171家日本设施发送了一份30项问卷，其中有高剂量率近距离放射治疗设备。总共返回了135份答复供分析。51家机构已经获得了某种带有施用器插入的3D成像模式，其中51家机构和3家机构分别使用了计算机断层扫描（CT）和磁共振成像（MRI）。在实际治疗计划中，分别有113家、20家和2家机构使用了X线片、CT和MRI。在43个使用施源器获取X光片和CT或MRI的设施中，29个仍使用X光片进行实际治疗规划，主要是因为时间和/或人员有限。在2.5年后的一项后续调查中，受访者包括38家最初仅使用X射线胶片的设施，但已表示计划采用3D-IGBT。其中，21例确实采用了插入施源器的CT成像。总之，3D-IGBT（主要是CT）已在22个设施（16%）中实施，未来将在72个设施（53%）中安装。时间和人员有限是主要障碍。
The purpose of this study is to survey the current patterns of practice, and barriers to implementation, of 3D image-guided brachytherapy (3D-IGBT) for cervical cancer in Japan. A 30-item questionnaire was sent to 171 Japanese facilities where high-dose-rate brachytherapy devices were available in 2012. In total, 135 responses were returned for analysis. Fifty-one facilities had acquired some sort of 3D imaging modality with applicator insertion, and computed tomography (CT) and magnetic resonance imaging (MRI) were used in 51 and 3 of the facilities, respectively. For actual treatment planning, X-ray films, CT and MRI were used in 113, 20 and 2 facilities, respectively. Among 43 facilities where X-ray films and CT or MRI were acquired with an applicator, 29 still used X-ray films for actual treatment planning, mainly because of limited time and/or staffing. In a follow-up survey 2.5 years later, respondents included 38 facilities that originally used X-ray films alone but had indicated plans to adopt 3D-IGBT. Of these, 21 had indeed adopted CT imaging with applicator insertion. In conclusion, 3D-IGBT (mainly CT) was implemented in 22 facilities (16%) and will be installed in 72 (53%) facilities in the future. Limited time and staffing were major impediments.
