Univariate survival analysis using the Kaplan-Meier method (Table 3) showed that normal presurgery serum CA19-9 values (P = 0.006, P = 0.005), metformin use (P = 0.003, P = 0.004), shallow tumor invasive depth (T1–3) (P = 0.004, P = 0.010), less lymph invasion (N) (P < 0.001, P < 0.001), positive E-cadherin expression (P = 0.001, P = 0.003), and negative vimentin expression (P = 0.019, P = 0.012) contributed to both longer DFS and OS. Here, VIM is linked to neoplasm.
