The prognostic significance of lymphovascular invasion in patients stratified by the TNM stage (log-rank test). Stage-match survival analysis showed that the presence of LVI was a prognostic factor for DSS in GC patients with stage I, stage II, stage III or stage IV (A-D). Stage-match survival analysis demonstrated that LVI was a statistically significant predictor for DFS in stage I or stage III and a tendency towards statistical significance was found in stage II (P = 0.086) or stage IV (P = 0.067, E-H).
