Compared with the implementation speed of image-guided adaptive brachytherapy for uterine cervical cancer, that of intracavitary and interstitial brachytherapy is slow, possible because it requires more invasive procedure of inserting needles directly into tumours. To accelerate the implementation speed of intracavitary and interstitial brachytherapy, a first hands-on seminar for image-guided adaptive brachytherapy and intracavitary and interstitial brachytherapy for uterine cervical cancer was held on 26 November 2022, supported by Japanese Society for Radiology and Oncology. This article deals with this hands-on seminar and difference of degree of confidence of participants in starting intracavitary and interstitial brachytherapy before and after the seminar.
The seminar consisted of lectures regarding intracavitary and interstitial brachytherapy in the morning and hands-on practice of needle insertion and contouring, as well as dose calculation practice using the radiation treatment system in the evening. Prior to and following the seminar, participants completed a questionnaire asking about their level of confidence in performing intracavitary and interstitial brachytherapy, expressed between 0 and 10 (the higher the number, the stronger the confidence).
A total of 15 physicians, six medical physicists and eight radiation technologists from 11 institutions attended the meeting. The median level of confidence before and after the seminar was 3 (range, 0-6) and 5.5 (range, 3-7), respectively, and a statistically significant improvement was observed (P<0.001).
It was suggested that the hands-on seminar on intracavitary and interstitial brachytherapy for locally advanced uterine cervical cancer improved the level of confidence of the attendees and propelled their motivation, through which it is expected that the implementation of intracavitary and interstitial brachytherapy will be accelerated.
与子宫颈癌图像引导自适应近距离放射治疗的实施速度相比，腔内和间质近距离放射治疗的速度较慢，这可能是因为它需要将针直接插入肿瘤的侵入性操作。为了加快腔内和间质近距离放射治疗的实施速度，2022 年 11 月 26 日，在日本放射肿瘤学会的支持下，举办了第一届子宫颈癌图像引导自适应近距离放射治疗和腔内及间质近距离放射治疗实践研讨会。本文介绍了该实践研讨会，以及研讨会前后参与者对开始腔内和间质近距离放射治疗的信心程度的差异。
研讨会包括上午的腔内和间质近距离放射治疗讲座，以及晚上的针插入和轮廓勾画以及使用放射治疗系统进行剂量计算实践。在研讨会之前和之后，参与者完成了一份问卷，询问他们对进行腔内和间质近距离放射治疗的信心程度，用 0 到 10 之间的数字（数字越高，信心越强）表示。
共有来自 11 个机构的 15 名医生、6 名医学物理学家和 8 名放射技师参加了会议。研讨会前后的中位数信心水平分别为 3（范围，0-6）和 5.5（范围，3-7），有统计学显著改善（P<0.001）。
腔内和间质近距离放射治疗局部晚期子宫颈癌的实践研讨会提高了与会者的信心水平，并激发了他们的积极性，预计这将加速腔内和间质近距离放射治疗的实施。
