(A011202) A Randomized Phase III Trial Comparing Axillary Lymph Node Dissection to Axillary Radiation in Breast Cancer Patients (cT1-3 NI) Who Have Positive Sentinel Lymph Node Disease After Neoadjuvant Chemotherapy
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.
