Error in Denominator in Results Text

The Original Investigation titled “Iodine Seed−Marking Protocol for Response-Guided Axillary Treatment After Systemic Therapy for Node-Positive Breast Cancer,” published online on August 28, 2025, and in the October 2025 issue, incorrectly stated in the Results section that the denominator used to calculate the percentage of patients diagnosed with invasive residual breast disease who received adjuvant systemic treatment was 215; instead, these 34 patients (16%) were from among the 135 patients with ypN0 disease. This article was corrected online.
