For patients whose primary tumor site was non-gastric, DFS-related factors included the Ki-67 index (p < 0.001) and surgical approach (p = 0.008), but TKI treatment (p < 0.001) and the Ki-67 index (p < 0.001) were closely related to OS (Fig. 2G, H). The gene discussed is MKI67; the disease is neoplasm.
