Conclusion:

The combination of ICIs/TTs and IORT for resected BMs does not result in increased toxicity and harbors a low risk of radiation necrosis, while yielding encouraging local control outcomes. By this combinatory treatment, time gaps between surgery and systemic treatment could be shortened or avoided. The definitive role of IORT in local control after BM resection will be defined in a prospective trial.

Purpose/Objective:

The number of academic centers offering (prostate) brachytherapy has substantially decreased in the past several years making training the new generation of brachytherapists increasingly challenging. While GEC-ESTRO has tried to meet this challenge by offering a school with didactics and hands-on training, supervision of initial cases by proctors is limited by trainer availability, need to travel and associated costs. Furthermore, there are additional shortcomings of the traditional Master-Apprentice model which is currently used in medical training. We propose a novel remote training platform (RTP) utilizing an extended reality headset that captures multiple live feeds from the theatre (first person camera, live ultrasound, and treatment planning) and projects them over a secured internet connection to a remote proctor who provides live instructions with annotations. Moreover, a survey of international experts was conducted to initially assess this RTP.

Material/Methods:

Beta Testing was performed utilizing a novel headset that combined a see-through optic display and an embedded webcam. The optic displayed the live images from the ultrasound/treatment planning laptop while the webcam captured the images from the student’s hands. The see-through vision of the headset allowed the students to look at their hands when performing the procedure while having the live video images projected to their eyes. A brachytherapy procedure was performed to test the system utilizing a prostate phantom. The procedure was observed on a laptop that was remote to the OR. A survey of international experts (n=56) was conducted to validate the system.
