Prostate Accurately Targeted Radiotherapy Investigation of Overall Treatment Time

Not Applicable

Completed

• Conditions: Prostatic Neoplasms
• Interventions: Radiation: Image-guided radiotherapy

• Registration Number: NCT01423474
• Lead Sponsor: CancerCare Manitoba

Brief Summary

The purpose of this study is to compare the toxicity of two new radiation schedules for the treatment of prostate cancer. Patients will be randomized to receive 5 treatments delivered every other day over 11 days, or once per week over 29 days. Both of these schedules are shorter than the standard treatment which is usually 39 treatments over 8 weeks.
