Background And Objective: Delivering radiotherapy to the bladder is challenging as it is a mobile, deformable structure. Dose-escalated adaptive image-guided radiotherapy could improve outcomes. RAIDER aimed to demonstrate the safety of such a schedule.

The implementation and early adoption of online adaptive radiotherapy (oART) has required the presence of clinicians, physicists and radiation therapists (RTT) at the treatment console. The impact on each of them is unique to their profession and must be considered for safe and efficient implementation. In the short term future, widespread adoption will depend on the development of innovative workflows, and rethinking of traditional roles and responsibilities may be required.

Purpose: Owing to substantial interfraction motion in cervical cancer, plan-of-the-day (PotD) adaptive radiation therapy may be of benefit to patients. Implementation is limited by uncertainty over how to generate the planning target volumes (PTVs). We compared published methods on our own patients.

Article Synopsis
  • The study aimed to identify the maximum tolerated dose (MTD) for treating muscle invasive bladder cancer using image-guided adaptive radiation therapy while monitoring long-term clinical outcomes.
  • A total of 59 patients with specific stages of bladder cancer participated, with their tumors receiving doses ranging from 68 to 72 Gy, and the MTD was found to be 70 Gy.
  • Results showed that 5-year overall survival was 58%, and the bladder preservation rate was high at 89%, with minimal severe acute toxicities reported.
