Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This will be a Phase II study evaluating the effectiveness and toxicity of a specific radiation therapy regimen. This choice of daily dose is based on the prior published experience showing safety and efficacy of hypofractionated regimens. The total dose is calculated to be effective for late effects which has been shown to be effective and safe in a large prospective Phase II study. If the hypothesis for the prostate is is true, then this regimen should be at least as effective or more effective for tumor control than the current conventional therapy.
