Surface guided radiation therapy: : An international survey on current clinical practice

• Introduction: Surface Guided Radiation Therapy (SGRT) is being increasingly implemented into clinical practiceacross a number of techniques and irradiation-sites. This technology, which is provided by different vendors, canbe used with most simulation- and delivery-systems. However, limited guidelines and the complexity of clinicalsettings have led to diverse patterns of operation. With the aim to understand current clinical practice a surveywas designed focusing on specifics of the clinical implementation and usage.Materials and methods: A 32-question survey covered: type and number of systems, quality assurance (QA),clinical workflows, and identification of strengths/limitations. Respondents from different professional groupsand countries were invited to participate. The survey was distributed internationally via ESTRO-membership,social media and vendors.Results: Of the 278 institutions responding, 172 had at least one SGRT-system and 136 use SGRT clinically.Implementation and QA were primarily based on the vendors’ recommendations and phantoms. SGRT wasmainly implemented in breast RT (116/136), with strong but diverse representation of other sites. Many (58/135) reported at least partial elimination of skin-marks and a third (43/126) used open-masks. The most commonimaging protocol reported included the combination of radiographic imaging with SGRT. Patient positioning(115/136), motion management (104/136) and DIBH (99/136) were the main applications.Main barriers to broader application were cost, system integration issues and lack of demonstrated clinical value.A lack of guidelines in terms of QA of the system was highlighted.Conclusions: This overview of the SGRT status has the potential to support users, vendors and organisations in thedevelopment of practices, products and guidelines.
