Study Summary

This phase II trial investigates the effect of extremely hypofractionated intensity modulated stereotactic body radiotherapy in treating patients with prostate cancer that has rising prostate specific antigen (PSA) after radical prostatectomy. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Primary Outcome

EPIC assessed the disease-specific aspects of prostate cancer and its therapies within the gastrointestinal summary domain. Response options for each EPIC item formed a Likert scale, and multi-item scale scores were transformed linearly to a 0-100 scale, with higher scores representing better Health-Related QoL.
