Extremely Hypofractionated Intensity Modulated Stereotactic Body Radiotherapy for Adjuvant or Salvage Treatment for Rising PSA After Radical Prostatectomy (EXCALIBUR)
Jonsson Comprehensive Cancer Center
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.
Description
PRIMARY OBJECTIVES: I. To determine the two-year change in patient-reported gastrointestinal (GI) symptoms based on the Expanded Prostate Cancer Index (EPIC) instrument following stereotactic body radiotherapy (SBRT) to the prostate bed and/or pelvic lymph nodes, with a comparison to historical control data for more prolonged radiation regimens. II. To determine the two-year change in patient-reported urinary (GU) symptoms based on the EPIC instrument following stereotactic body radiotherapy (SBRT) to the prostate bed and/or pelvic lymph nodes, with a comparison to historical control data fo…
