Patient on couch time for this new adaptive technique is approximately 40-minutes, compared to 10-minutes for our previous standard non-adaptive IGRT technique. All oART patients have a backup IGRT plan, for scheduled machine services or breakdowns. To account for longer on-couch time we modified the patient bladder filling protocol from 350ml 1-hour prior to RT (standard IGRT) to 350ml 30-minutes prior to oART. The aim of this project was to assess patients’ tolerability of the extended on-couch time and the modified bladder filling protocol for oART. Material/Methods: The questionnaire given and collected is from a validated patient-reported treatment experience questionnaire in its original state (2) and assessed situational discomfort, physical discomfort, situational coping, information needs, environmental coping and psychological coping. The questionnaire was Digital Poster 4301 composed of 18 questions, each scored using a 4- point Likert scale with the following options: not at all (0), slightly (1), moderately (2) and very (3). Patients

Conclusion: This study collected perspectives of HNC patients on supine and upright RT approaches. Attitudes to HNC RT were varied and multi-dimensional but there was consensus that their experience of conventional RT was gruelling and highly distressing. Participants endorsed upright radiotherapy as a human solution, with the potential to reduce swallowing/breathing difficulties, enhance comfort, and facilitate radiographer interaction.
