Study type | Interventional |
This phase II trial tests whether magnetic resonance imaging (MRI)-guided hypofractionated radiation therapy works to reduce treatment time and side effects in patients with high risk prostate cancer. MRI-guided hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time directly to diseased tissue, reducing damage to healthy tissue. Using MRI-guided radiation therapy on areas of the prostate and pelvic lymph nodes may shorten overall treatment time compared to the longer standard of care therapy and may reduce the number and/or duration of side effects.

Primary | Rate of late grade 2+ genitourinary (GU) toxicity | Per Common Terminology Criteria for Adverse Events version 5.0 compared to rate of toxicity in POP-RT trial. Will be estimated for the entire sample that receives the intervention, treating death from any cause (other than treatment) as a competing risk and censoring subjects who drop out before experiencing toxicity at time of last follow-up. A point estimate of cumulative incidence at 1 year will be estimated from this curve along with a two-sided 90% confidence interval. If the upper bound of the interval is less than 20%, the null hypothesis will be rejected. | At 1 year | |
Secondary | Incidence of acute GU and gastrointestinal (GI) toxicity | Will be estimated using a binomial proportion and exact 95% confidence interval. | At baseline | |
