Phase II Study of Single-Dose Image-Guided Radiotherapy (SDRT) for Prostate Cancer

Previously untreated patients with prostate cancer will be treated with 24Gy in in one session.

Patients enrolled in the study will undergo IGRT-VMAT with state-of-the-art treatment-planning and quality assurance procedures with emphasis on normal tissue sparing and delivery accuracy via the use of devices that ensure stability and beam location reproducibility.

A rectal balloon with air filling will be used for prostate target immobilization and anatomical reproducibility.

A urethral catheter loaded with beacon transponders will be used to ensure set-up reproducibility and online target tracking.
