A multicentre, randomised, phase II study of hypofractionated bladder radiotherapy with or without image guided adaptive planning
Disease site: Bladder cancer, urological cancers
Treatment modality: Radiotherapy
Status: In follow-up
HYBRID is a multicentre, phase II, randomised controlled trial to assess whether image guided adaptive planning radiotherapy techniques can lead to a reduction in the level of acute non genitourinary side effects experienced by patients with muscle invasive bladder cancer unsuitable for daily radical radiotherapy.
62 patients will be recruited from UK sites over two years. All patients will receive weekly hypofractionated radiotherapy for six weeks and will be randomised between either standard or adaptive planning. Patients in the adaptive planning group will have three radiotherapy plans generated and a CT scan prior to each treatment delivery will be used to select the most appropriate plan of the day, adapting to variations in bladder position. Participants will be followed up at regular intervals for 24 months, and then annually thereafter.
We have prepared a lay summary of the HYBRID results, which can be viewed and downloaded here.
