This randomized phase III trial studies axillary lymph node dissection to see how well it works compared to axillary radiation therapy in treating patients with node-positive breast cancer treated with neoadjuvant chemotherapy followed by surgery. Lymph node dissection may remove cancer cells that have spread to nearby lymph nodes in patients with breast cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. This study will evaluate whether radiation therapy is as effective as lymph node dissection.

  • Clinical stage T1-3 N1 M0 
  • No other malignancy within 5 years of registration 
  • Patients must have completed all planned chemotherapy prior to surgery.  Patients must have completed at least 6 cycles of neoadjuvant chemotherapy consisting of an anthracycline and/or taxane-based regimen without evidence of disease progression in the breast or the lymph nodes. 
  • Patients with HER-2 positive tumors must have received neoadjuvant trastuzumab, trastuzumab + pertuzumab, or other approved anti-HER-2 therapy 
  • No neoadjuvant endocrine or radiation therapy
  • No prior history of breast cancer or axillary surgery in opposite breast
  • No history of prior or concurrent contralateral invasive breast cancer. Benign breast disease, LCIS or DCIS of contralateral breast is allowed.
