Brief Summary:
During 3D-conformal external beam radiation therapy treatments for prostate cancer, the prostate gland moves. The purpose of this study is to determine whether the placement of a prostate immobilization device into the rectum during radiation treatments will decrease the risk of rectal bleeding that is sometimes seen as a late effect from radiation.

Condition or disease Intervention/treatment Phase
Prostate Cancer Device: Prostate Immobilization Device Phase 2

Detailed Description:
  • MRI using an endorectal coil done prior to treatment for staging.
  • Baseline Quality of Life (QOL) assessment will be completed prior to treatment.
  • Total androgen suppression is initiated and will continue for at least 6 months.
  • Prostate Immobilization Device (PID) placed during the planning session.
  • PID will be placed daily for the first 15 3D external beam radiation treatments.
  • QOL assessment and follow-up will take place every 6 months for 3 years.
