Key clinical point: The omission of axillary surgery leads to non-inferior outcomes compared to sentinel lymph node biopsy (SLNB) and may not be necessary in patients with early breast cancer (BC) having a tumor diameter ≤ 2 cm and negative results for preoperative axillary lymph node ultrasonography.
Major finding: The rates of 5-year distant disease-free survival were comparable in patients who underwent SLNB and those who did not undergo axillary surgery (97.7% vs 98.0%; hazard ratio 0.84; noninferiority P = .02).
Study details: Findings are from the phase 3 SOUND trial including 1405 women with BC having a tumor diameter ≤ 2 cm and negative preoperative axillary ultrasonography results who were randomly assigned to undergo either SLNB or no axillary surgery.
Disclosures: This study did not disclose any funding source. Some authors declared receiving personal fees from various sources.
