Breast Cancer
Patients with cT1-2cN1 HR+/HER2- tumors who are scheduled to undergo upfront surgery will undergo AUS at the enrolling institution to characterize suspicious-appearing lymph nodes, as is part of routine practice.
|
Procedure: Breast surgery
Patients will undergo SLNB with dual-tracer mapping with technetium-99m sulfur colloid and lymphazurin blue dye, in accordance with routine clinical practice. |
- evaluate rates of axillary lymph node dissection [ Time Frame: 2 years ]Completion ALND will be required if metastases are present in ≥3 SLNs on pathologic evaluation.
