Patients with low sTK1 at the end of adjuvant treatment (visit EoT) by both median and the predefined cutoff (250 DuA) had numerically better DFS (Supplementary Fig. 3), however the difference was not statistically significant in models adjusted for pCR, Ki67, treatment arm, tumor grade, tumor size, ER status, and node status (Supplementary Table 4). The gene discussed is MKI67; the disease is neoplasm.
