  • Notable: the trial’s plan changed such as a big move in its timeline or size, a new primary endpoint, sponsor or phase, or recruiting opened or resumed.
  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Interstitial brachytherapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Combining interstitial brachytherapy with external-beam radiation therapy may kill more tumor cells. It is not yet known whether interstitial brachytherapy is more effective with or without external-beam radiation therapy in treating prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of interstitial brachytherapy with or without external-beam radiation therapy in treating patients who have prostate cancer.
