Study Details

Study Description

Brief Summary

This study will ultimately aim to evaluate the side effects of treatment by asking 20 subjects to receive post-operative radiotherapy for prostate cancer with the treatment plan adapted after the first week of treatment to account for changes in the target shape. These patients will be asked to complete toxicity scores and a quality of life questionnaire at the start and completion of treatment, and at 3 months 1, 2 and 5 years from the start of radiotherapy. These results will be used to determine the feasibility of the proposed approach, and obtain early estimates of improvements in uncertainty margin requirements for this population of patients.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Post-Operative adaptive radiotherapy

All Patients enrolled in this study will have additional scans (Cone-Beam CT, MRI) daily during their treatment. This extra imaging will help us see any changes that might have occurred during radiation treatment and update the treatment plan to include these changes before patient treatment is continued.

  • Outcome Measures

    Primary Outcome Measures

    1. Change in radiation dose delivered to target volumes and normal tissue [5 years]

    Secondary Outcome Measures

    1. Time for radiotherapy replanning [5 years]

    2. Volumetric modulated arc therapy impact in a clinical adaptive Radiotherapy workflow. [5 years]

      Feasibility will be assessed by the time required to perform the adaptive intervention

    3. Toxicity associated with the adaptive radiotherapy technique. [5 years]

      Assessments of gastrointestinal and genitourinary complications using the Common Toxicity Criteria for Adverse Events scoring system and the Expanded Prostate Cancer Index Composite questionnaire.
