But what's more important is (2) the substantial irrelevance of nodal tumor burden within node-positivity: as the MDA review [Hernandez-Aya et al., J Clin Oncol 2011] established, when comparing N1 (1 - 3 nodes) with N2 (4 - 9 nodes) and N3 (>= 10 nodes) disease regardless of tumor size, there were no significant differences in either recurrence-free survival (RFS) nor overall survival (OS), so that once there is lymph node involvement in TNBC, the prognosis is not greatly affected by the absolute number of positive lymph nodes.
