Radiation Therapy or Standard Therapy in Treating Women With Stage II Breast Cancer Who Have Undergone Mastectomy
- Conditions
- Breast Cancer
- Interventions
- Radiation: radiation therapyProcedure: standard follow-up care
- Registration Number
- NCT00966888
- Lead Sponsor
- Medical Research Council
- Brief Summary
RATIONALE: Radiation therapy uses high-energy x-rays or other types of radiation to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether radiation therapy is more effective than observation after mastectomy in treating women with stage II breast cancer.
PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with standard therapy in treating women with stage II breast cancer who have undergone mastectomy.
- Detailed Description
OBJECTIVES:
* Determine the overall survival of women at intermediate risk for locoregional recurrence of breast cancer treated with ipsilateral chest wall adjuvant radiotherapy after mastectomy.
OUTLINE: This is a multicenter study. Patients are randomized to 1 of 2 treatment arms.
* Arm I: Beginning 12 weeks after mastectomy or 6 weeks after adjuvant chemotherapy, patients undergo radiotherapy 5 days a week for 3-5 weeks in the absence of disease progression or unacceptable toxicity.
* Arm II: Patients receive standard of care and observation only. After completion of study therapy, patients are followed up twice in the first year, and then annually for up to 10 years.
