MKI67 and neoplasm: The current study extends this finding into TNBC: while the global Ki67 percentage in TNBC was not significantly associated with BCSS in univariate analysis, Ki67-entropy demonstrated significant prognostic value both in univariate analysis (HR = 5.01, p = 0.0006) and as an independent prognostic factor (HR = 5.39, p = 0.0013) in the context of tumor invasion stage (Table 4, model 2).
