A Randomized Phase III Trial Evaluating the Role of Axillary Lymph Node Dissection in Breast Cancer Patients (cT1-3 N1) 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.
• Clinical stage T1-3 N1 M0 breast cancer at diagnosis (prior to the start of neoadjuvant chemotherapy)
• All patients must have had an axillary ultrasound with fine needle aspiration (FNA) or core needle biopsy of axillary lymph nodes documenting axillary metastasis at the time of diagnosis, prior to or at most 14 days after starting neoadjuvant chemotherapy. Note: Biopsy of intramammary nodes does not fulfill eligibility criteria.
• Patients must have completed all planned chemotherapy prior to surgery. Sandwich chemotherapy is not allowed (i.e. chemotherapy planned to be given after 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.
