Brief Summary:

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.

PURPOSE: This phase I trial is studying the best dose of intensity-modulated radiation therapy in treating patients with prostate cancer.

Condition or disease Intervention/treatment Phase
Prostate Cancer Radiation: hypofractionated radiation therapy Radiation: intensity-modulated radiation therapy Phase 1

Detailed Description:


  • To test the feasibility of delivering hypofractionated intensity-modulated radiotherapy to the prostate and pelvic nodes of patients with prostate cancer.
  • To determine the optimal dose level of this treatment regimen to be used in future studies.

OUTLINE: Patients are stratified according to small bowel total volume (low small bowel volume < 450 cc vs high small bowel volume ≥ 450 cc).

Patients undergo hypofractionated intensity-modulated radiotherapy to the prostate and pelvis for 4 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 5 years and then annually thereafter.
