MKI67 and neoplasm: Age (p = 0.009, only for OS), tumor size (p = 0.005 and p<0.001 for DFS and OS, respectively), lymph node involvement (p = 0.001 and p = 0.004 for DFS and OS, respectively), family history (p = 0.048 and p = 0.024 for DFS and OS, respectively), Ki-67 high index (p = 0.047, only for DFS), and P53 (p = 0.020 and p = 0.007 for DFS and OS, respectively) were significant prognostic factors for TNBC (Tables 4 and 5).
