MKI67 and neoplasm: Kaplan-Meier analysis suggested that age (HR=1.042, 95%CI, 1.021-1.064, p<0.001), Ki67 (HR=1.030, 95%CI, 1.022-1.038, p<0.001), Mitoses (HR=1.013, 95%CI, 1.009-1.018, p<0.001), NLR (HR=6.327, 95%CI, 3.676-10.890, p<0.001), CEA/CA19-9 (HR=4.829, 95%CI, 2.837-8.218, p<0.001), T stage (HR=1.865, 95%CI, 1.101-3.161, p=0.021), distant metastasis (HR=6.260, 95%CI, 3.405-11.509, p<0.001), tumor size (HR=1.676, 95%CI, 1.009-2.785, p=0.046) were significantly associated with poor overall survival in G-NENs.
