Axillary Management After Neoadjuvant Chemotherapy

"For SLNB evaluation, multiple sections of the excised lymph node were stained with hematoxylin and eosin (H\&E) at a thickness greater than 2 mm. Lymph nodes with metastasis greater than 2 mm were defined as positive SLNB. Macroscopic metastasis was considered positive in the evaluation for the axilla, while benign histological characteristics were considered negative. The presence of micrometastasis and isolated tumor cells was also noted. The size and diameter of the metastatic lymph node were considered in the evaluation.~SLNB technique using isosulfan blue dye was performed for axillary evaluation, and all patients had the clipped lymph node excised under ultrasound guidance with a guide wire placed preoperatively."
