Highlights The patterns of practice for adaptive radiotherapy were evaluated for 177 centres. Over half performed ad-hoc adaption but less than a third used specific protocols. CBCT was the main imaging modality in general but MR was used for daily replanning. 2/3 centres wished to implement ART; 40% of them had plans to do it within 2 years. The main barriers were human/material resources and technical limitations.

Highlights Real-time respiratory motion management (RRMM) practice, evaluated for 200 centres. Sixty-eight percent of respondents used RRMM for at least one tumour site. Across all tumour sites, external marker was the main RRMM signal used. Overall 71% of respondents wished to implement RRMM for a new treatment site. The main barriers were human/financial resources and capacity on the machine.
