Summary
This phase III trial studies compares CT-guided stereotactic body radiation therapy and MRI-guided stereotactic body radiation therapy (SBRT) in treating prostate cancer. Image-guided SBRT is a standard treatment for prostate cancer, which combines imaging of the cancer within the body with the delivery of therapeutic radiation doses produced on a linear accelerator machine. Imaging modalities for image-guided SBRT can be either computed tomography imaging (CT), magnetic resonance imaging (MRI), or a combination of the two. This research is being done to help determine whether there are benefits to MRI-guidance over CT-guidance in patients who are receiving the same radiation dose by SBRT to treat prostate cancer.
Description
PRIMARY OBJECTIVE:
I. To determine whether (MRI)-guided stereotactic body radiotherapy (SBRT) improves acute physician-scored genitourinary (GU) toxicity when compared with standard computed tomography (CT)-guided SBRT for prostate cancer (PCa).
SECONDARY OBJECTIVES:
I. To determine whether there are differences in acute grade >= 2 gastrointestinal (GI) toxicity as assessed by the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 scale, following MRI-guided SBRT versus CT-guided SBRT.
II. To determine whether there are differences in 5-year cumulative incidences of late grade >= 2 GU and GI physician-reported toxicity, following MRI-guided SBRT versus CT-guided SBRT.
III. To quantify the temporal changes in patient-reported quality of life (QOL) outcomes, as assessed by the Expanded Prostate Cancer Index-26 (EPIC-26), International Prostate Symptom Scores (IPSS), and Sexual Health Inventory for Men (SHIM) QOL indices, following MRI-guided SBRT.
IV. To determine whether there are differences in 5-year biochemical recurrence-free survival (BCRFS) following MRI-guided SBRT.
V. To observe the proportion of SBRT fractions for which on-line adaptive radiotherapy is required due to changes in organ-at-risk anatomy.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients undergo 5 fractions of CT-guided SBRT over 14 days in the absence of disease progression or unacceptable toxicity.
GROUP II: Patients undergo 5 fractions of MRI-guided SBRT over 14 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 4 years, and then yearly thereafter.
