Purpose/Objective:

In radiotherapy (RT) planning for colorectal cancers it is essential to minimise dose to normal tissue. Acute and late side effects can negatively impact patients’ long term bowel and bladder function thus quality of life 1 . The radiation tolerance of small bowel is known to be sensitive even at lower dose constraints. Recommendations are to minimise dose to below the accepted constraints where possible 2 . It is important during planning to move small bowel away from the target with a full bladder. It is crucial to create this distance from the target where the effects of differential motion can not be accounted for. There is limited evidence on the impact of hydration in bladder filing for pelvic patients,

An RTT led hydration information service was developed for all colorectal patients. We aimed to determine the impact of the service on optimal bladder volumes for patients receiving RT for colorectal cancer.

Material/Methods:

All colorectal patients treated between Sep 2022-Aug 2023 were included. A hydration task was created within Aria (Varian Medical Systems, Palo Alto) as part of the patients’ carepath to ensure a hydration call was carried out by the RTT team. The call was made 5 days or less prior to the CT planning scan. The task had a questionnaire script to ensure the information provided was standardised (Table 1).

A maximum of three call attempts were made before recording as unable to contact the patient.
