Metastatic Prostate Cancer | Radiation: MR-Guided Prostate SBRT | Not Applicable |
The MRidian ViewRay offers delivery of prostate SBRT with real-time MR guidance, which provides superior soft-tissue differentiation with excellent visualization of the prostate. This ViewRay platform offers the ideal setting for this study, that aims at precisely delivering prostate SBRT with a simultaneous integrated boost (when indicated) to visible nodules.
In this study, we hope to demonstrate the safety and feasibility of using 36.25 Gy in 5 fractions, plus a simultaneous integrated boost (when indicated), in patients with metastatic prostate cancer.

MR-Guided Prostate SBRT |
Radiation: MR-Guided Prostate SBRT
Prostate SBRT has become a standard of care for the treatment of localized prostate cancer. Radiation is delivered to the prostate and seminal vesicles in 5 treatment sessions (fractions). Doses ranging from 35-45 Gy in 5 fractions have demonstrated good outcomes with acceptable toxicity when planning is delivered appropriately. |
- Change in Number of Subjects with Adverse events will be collected [ Time Frame: baseline, 3-6months and at 9-12 months. ]Treatment will be deemed safe if there is no more than 3 acute Grade 3 gasterointestinal/genitourinary events within the first 30 days after treatment completion. Adverse events can be unexpected or expected, related to treatment.
- Change in Quality of life questionnaires will be assessed. [ Time Frame: baseline, 3-6months and at 9-12 months. ]Expanded Prostate Cancer Index Composite (EPIC) short form questionnaire. The Expanded Prostate Cancer Index Composite (EPIC) is a comprehensive instrument designed to evaluate patient function and bother after prostate cancer treatment. Scores range from 0 to 100, lower scores indicate worse outcomes and higher EPIC scores represent better outcomes. QOL assessments will occur at baseline, 3-6 months, and at 9-12 months.
- Change in The International Prostate Symptom Score (I-PSS) will be assessed. [ Time Frame: baseline, 3-6months and at 9-12 months. ]
The International Prostate Symptom Score (I-PSS) is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the patient to choose one out of six answers indicatingincreasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic).
Mild (symptom score less than of equal to 7) Moderate (symptom score range 8-19) Severe (symptom score range 20-35)
