Sentinel Lymph Node Biopsy after Chemotherapy before Surgery in Identifying Residual Cancer Cells in Patients with Locally Advanced Breast Cancer

Trial Status: active

This clinical trial studies how well sentinel lymph node biopsy after chemotherapy before surgery works in identifying residual cancer cells in patients with breast cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced). Sentinel lymph node biopsy is the removal and examination of the sentinel node(s) (the first lymph node[s] to which cancer cells are likely to spread from a primary tumor) and may help to allow patients with breast cancer to have fewer lymph nodes removed as part of their cancer care in the future.
