Data from patients with infiltrating BC who underwent BC surgery after NAST and intraoperative sentinel lymph node biopsy (SLNB) performed by One Step Nucleic acid Amplification (OSNA) technique during 2017 and 2018 were analyzed. ALND was performed according to the protocol of each center, based on three different TTL cut-offs (TTL\u2009&gt;\u2009250, TTL\u2009&gt;\u20095000, and TTL\u2009&gt;\u200915,000 CK19-mRNA copies\/\u03bcL for centers 1, 2, and 3, respectively).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 157 BC patients were included in the study. No significant differences in DFS were observed between centers (Hazard ratio [HR] center 2 vs 1: 0.77; <jats:italic>p<\/jats:italic>\u2009=\u20090.707; HR center 3 vs 1: 0.83; <jats:italic>p<\/jats:italic>\u2009=\u20090.799). Patients with ALND had a shorter DFS (HR 2.43; <jats:italic>p<\/jats:italic>\u2009=\u20090.136), albeit not statistically significant. Patients with a triple negative subtype had a worse prognosis than those with other molecular subtypes (HR 2.82; <jats:italic>p<\/jats:italic>\u2009=\u20090.056).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>No significant differences in DFS were observed between three centers with different surgical approaches to ALND based on different TTL cut-offs in patients with BC after NAST. These results suggest that restricting ALND to those patients with TTL\u2009\u2265\u200915,000 copies\/\u03bcL is a reliable approximation, avoiding unnecessary morbidities caused by ALND.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s10549-023-06954-8","type":"journal-article","created":{"date-parts":[[2023,5,23]],"date-time":"2023-05-23T11:02:11Z","timestamp":1684839731000},"page":"203-215","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Value of total tumor load as a clinical and pathological factor in the prognosis of breast cancer patients receiving neoadjuvant treatment.
