Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary safety purpose of this study is to estimate the rates of immediate and long-term high grade (grade 3-5) gastrointestinal and genitourinary side effects during the five years after TrueBeam stereotactic body radiotherapy in low-risk and intermediate-risk prostate cancer patients. The primary efficacy purpose is to compare 5 year biochemical disease free survival rates with TrueBeam to 5 year biochemical diseases free survival rates with dose-escalated external beam radiation therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The prescribed PTV dose of 36.25Gy shall be given in 5 fractions using the Truebeam STx.

At one week after treatment, toxicity and AUA score will be evaluated. At 1 month following treatment, patients will be assessed for acute toxicity, and will fill out AUA form, SF-12, EPIC-26, SHIM and Utilization of Sexual Rx/Devices. At 3, 6, 12, 18, and 24 month intervals (and every 6 months thereafter, through year 5, and annually through year 10, if investigators opt to continue past year 5), patients will be seen and evaluated, including a history, physical exam, ECOG performance status, PSA, toxicity evaluation, and AUA score. In addition, at 6 months, 12 months and annually thereafter, the SF-12, EPIC-26, SHIM and Utilization of Sexual Medications/Devices will be administered. Examination and studies may be done at outside facility.

A prostate biopsy will be performed at time of biochemical or local clinical failure, and is encouraged at 2 years following treatment and at time of distant failure.
