Purpose:
This study describes the development, implementation, and evaluation of an online educational program on CT-based image-guided adaptive brachytherapy for locally advanced cervical cancer (LACC) by BrachyAcademy, in collaboration with the lead author of the IBS-GEC ESTRO-ABS CT-based contouring recommendations.
Materials And Methods:
In 2023-24, the program comprised three components: a procedural video, a webinar, and an interactive online contouring workshop. The workshop included two homeworks on LACC cases using ProKnow software. Participants delineated high-risk clinical target volume (CTVHR) and intermediate-risk clinical target volume (CTVIR) and organs at risks. Postworkshop contouring efficiency was assessed by comparing participants' contours to master contours. Feedback was collected through postcourse evaluation forms.
Results:
The procedural video reached 487 individuals from 70 countries; the webinar engaged 148 participants from 39 countries, with an additional 115 on-demand viewers. Thirty-five radiation oncologists from 20 countries participated in the workshop, and 27 (77%) completed both homeworks for both cases. Comparison between homeworks demonstrated significant improvements in CTVHR and CTVIR contouring. Postcourse evaluation forms (n = 25) showed that 92% of respondents' expectations were fully met, with an average satisfaction score of 9.3/10.
Conclusion:
Participation highlighted a broad, global interest in CT-based brachytherapy education. Strategies are being explored to scale up the online program and integrate it with in-person workshops.
