To determine which parameters best correlated with death and recurrence, we performed regression analysis on continuous variables, i.e., age, tumor stage, tumor size, Weiss score, and Ki67 LI, as well as dichotomized variables, such as presence or absence of necrosis and venous invasion, grouped tumor stage (I–II vs III–IV), tumor size (cut-off = 6 cm), RMS (R0 vs R1), total Weiss score (cut-off value = 6), and Ki67 LI (cut-off value = 20%) (Table 4). The gene discussed is MKI67; the disease is neoplasm.
