Summary
Brief summary (as posted)
RATIONALE: External-beam radiation therapy uses high-energy x-rays to kill tumor cells. Implant radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving external-beam radiation therapy or implant radiation therapy after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether radiation therapy is more effective than observation when given after surgery in treating stage I endometrial cancer. PURPOSE: This randomized phase III trial is studying external-beam radiation therapy or implant radiation therapy to see how well they work compared with observation in treating patients who have undergone surgery for stage I endometrial cancer.
