Hands-on seminar for image-guided adaptive brachytherapy and intracavitary/interstitial brachytherapy for uterine cervical cancer

Supported by JASTRO, a first hands-on seminar for intracavitary and interstitial brachytherapy for cervical cancer was held to spur the implementation speed of intracavitary and interstitial brachytherapy, which improved the level of confidence of the attendees. Objective 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. Methods 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). Results 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). Conclusion 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.
