Kaplan–Meier survival analyses elucidating the profound prognostic influence of lymphovascular invasion (LVI) on recurrence-free survival (RFS) and overall survival (OS) amongst ESD-eligible EGC patients. (a) LVI is identified as a significant predictor of reduced RFS (HR = 4.8, 95% CI 2.6–8.9, p < 0.001). (b) LVI is associated with a significant reduction in OS (HR = 4.8, 95% CI 2.4–9.6, p < 0.001).
