MKI67 and neoplasm: Kaplan-Meier analysis confirmed that tumor stage (p = 0.014), nodal status (p < 0.001), lymphangiosis carcinomatosa (p = 0.025), hemangiosis carcinomatosa (p = 0.017), positive resection margin (p < 0.001), grade (p = 0.041) and UICC stage (p = 0.007) correlated inversely with OS, and Ki-67 correlated directly with OS (p = 0.001).
