Radiation Therapy or Standard Therapy in Treating Women With Stage II Breast Cancer Who Have Undergone Mastectomy

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

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.

Arms Assigned Interventions
Experimental: 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.
Radiation: radiation therapy
Chest wall radiotherapy
Active Comparator: Arm II
Patients receive standard of care and observation only.
Procedure: standard follow-up care
No intervention

Detailed Description:


  • 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.

Ages Eligible for Study:   Child, Adult, Senior

    • No internal mammary nodes visible on sentinel node scintigraphy in the absence of negative histology NOTE: *Isolated tumor cells not counted as micrometastases
  • Underwent total mastectomy (with minimum of 1 mm margin clear of invasive cancer and DCIS) and axillary surgery with staging procedure

    • Must have undergone adjuvant systemic chemotherapy if indicated for intermediate-risk breast cancer
    • Patients undergoing immediate breast reconstruction allowed
  • No known BRCA1 and BRCA2 carriers
  • Hormone receptor status not specified


  • Menopausal status not specified
  • Not pregnant
  • Fit for adjuvant chemotherapy, adjuvant endocrine therapy, and post-operative radiotherapy
  • No prior or concurrent malignancy except curatively treated nonmelanomatous skin cancer or carcinoma in situ of the cervix


  • See Disease Characteristics
  • No concurrent trastuzumab
  • No prior neoadjuvant systemic therapy
