“…These benefits correspond to the advantages seen during applications in adult treatments. 11 , 19 The improved initial patient set-up has the potential to decrease the frequency of verification images, which could reduce set-up time and minimize imaging dose exposure (for CBCT, the dose per image ranges from 1 up to 3 mGy depending on the anatomical region that needs to be imaged 29 ). For internal treatment sites, the target position is not always well represented by a surface image, 30 therefore SGRT is often considered a complement to radiographic image guidance.…”

“… 9 For targets located in the extremities, SGRT can lead to an improved treatment posture thanks to the extended field-of-view, thereby reducing the need for repositioning, or re-entering the room to adjust the patient, and so reducing the overall time per session. 10 , 11 Moreover, it has been shown that SGRT can improve the efficiency of the radiotherapy (RT) workflow, by reducing the time required to set-up the patient, 12 , 13 and patient safety. 14 …”

Introduction Surface guided radiotherapy (SGRT) is increasingly being implemented to track patient’s surface movement and position during radiation therapy. However, limited information is available on the SGRT use in paediatrics. The aim of this double survey was to map SIOPE (European Society for Paediatric Oncology) -affiliated centres using SGRT and to gain information on potential indications, observed or expected benefits. Materials and methods A double online survey was distributed to 246 SIOPE-affiliated radiotherapy centres. Multiple choices, yes/no and open answers were included. The first survey (41 questions) was active from February to March 2021. A shortened version (13 questions) was repeated in March 2023 to detect trends in SGRT use within the same community. Results Respectively, 76/142 (54%) and 28/142 (20%) responding centres used and planned to use SGRT clinically, including 4/34 (12%) new centres since 2021. Among the SGRT users, 33/76 (43%) already applied this technology to paediatric treatments. The main benefits of improved patient comfort, better monitoring of intrafraction motion and more accurate initial patient set-up expected by future users did not differ from current SGRT-users (P = 0.893). Among non-SGRT users, the main hurdles to implement SGRT were costs and time for installation. In paediatrics, SGRT is applied to all anatomical sites. Conclusion This work provides information on the practice of SGRT in paediatrics across SIOPE-affiliated radiotherapy centres which can serve as a basis for departments when considering the purchase of SGRT systems. Advances in knowledge Since little information is available in the literature on the use of SGRT in paediatrics, the results of this double survey can serve as a basis for departments treating children when considering the purchase of an SGRT system.
