Sentinel Lymph Node Surgery After Neoadjuvant Chemotherapy in Patients With Node-Positive Breast CancerThe ACOSOG Z1071 (Alliance) Clinical Trial
According to the Z1071 study, for patients who had positive nodes pre-chemotherapy and then had a sentinel node biopsy, the false-positive rate was less than 10% if dual tracer was used, greater than two sentinel nodes were removed, and any clipped nodes were included.
If only one lymph node was removed, the false-negative rate was unacceptably high and further axillary surgery was needed. Until the Alliance 11202 trial is completed, the standard treatment remains an axillary dissection for positive nodes after chemotherapy.
