Standard Versus Intensity-Modulated Pelvic Radiation Therapy in Treating Patients With Endometrial or Cervical Cancer

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. 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 randomized phase III trial is studying two different methods of radiation and their side effects and comparing how well they work in treating endometrial and cervical cancer after surgery.
