Overall, 643 clinical stage T1-3 N0 patients who did not receive neoadjuvant therapy and had one to two metastatic SLNs at the time of surgery were included. Propensity score matching was performed between the SLNB alone and ALND groups, adjusting for clinical <jats:italic>T<\/jats:italic> stage and number of metastatic SLNs. In total, 237 patients were allocated to each group.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Mean number of metastatic SLNs was 1.2 for the SLNB group and 1.6 for the ALND group. With a median follow-up of 65.0\u00a0months, 5\u00a0year disease-free survival was 90.8% for the SLNB group and 93.9% for the ALND group (hazard ratio [HR] 1.35, 95% confidence interval [CI] 0.70\u20132.58; <jats:italic>p\u2009<\/jats:italic>=\u20090.36). 5\u00a0year ipsilateral locoregional recurrence-free survival (LRRFS) was not significantly different between the two groups (95.1% and 98.3% for the SLNB and ALND groups, respectively) [HR 1.86, 95% CI 0.69\u20135.04; <jats:italic>p\u2009<\/jats:italic>=\u20090.21]. In the SLNB group, patients who received radiation therapy (RT) showed superior 5\u00a0year LRRFS than patients who did not receive RT (100% vs. 92.9%; <jats:italic>p\u2009<\/jats:italic>=\u20090.02).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Collectively, our findings suggest that SLNB could afford comparable outcomes to ALND in patients with early breast cancer and one to two metastatic SLNs who underwent TM.
