MKI67 and neoplasm: Univariate analysis revealed that progression was associated with the following factors: Ki67 (HR = 1.06, 95% CI = 1.02–1.10; p = 0.001), mitotic count (HR = 1.09, 95% CI = 1.03–1.17; p = 0.006), tumor size (HR = 1.14, 95% CI = 1.01–1.29; p = 0.041), distant metastases at diagnosis (HR = 6.62, 95% CI = 2.09–20.93; p = 0.001), stage III/IV ENSAT (HR = 8.32, 95% CI = 1.84–37.71; p = 0.006), and R1–R2 resection status (HR = 5.24, 95% CI = 1.08–25.47; p = 0.040).
