A Phase III Randomized Study of Hypofractionated 3D-CRT/MRT Versus Conventionally Fractionated 3D-CRT/MRT in Patients With Favorable-Risk Prostate Cancer

new search

Trial Conditions
  • Prostate Cancer
What is the purpose of this trial?

RATIONALE: Giving radiation therapy that uses a 3-dimensional (3-D) image of the tumor to help focus thin beams of radiation directly on the tumor, and giving hypofractionated radiation therapy (higher doses over a shorter period of time), may kill more tumor cells and have fewer side effects. It is not yet known which radiation therapy regimen is more effective in treating prostate cancer. PURPOSE: This randomized phase III trial is studying several different radiation therapy regimens to compare how well they work in treating patients with stage II prostate cancer.
