MKI67 and neoplasm: In addition, when the whole tumour cohort was stratified into three groups according to the 4 and 10% cut-off thresholds, we observed that outcome of patients with tumours pertaining to the three relevant Ki-67 categories (<4, 4–9, ≥10%) was different in terms of both overall survival and time to progression (p = 0.0052 and <0.0001, respectively; Table 1 and Fig. 4), with cases displaying a Ki-67 ≥ 10% running a poorer survival.
