Traditionally tested factors such as NPI value of >4, MI of >25 and Ki67 expression in >50% tumor cells (score 7 in our evaluation) were statistically linked with worse RFS (pNPI = 0.011, pMI = 0.002, pKi67 = 0.001), while hormone receptor positivity was linked to longer RFS (p = 0.002). This evidence concerns the gene MKI67 and neoplasm.
