Kaplan-Meier curve of disease-free survival (DFS) () and overall survival (OS) () stratified by liver margin status. Median DFS and OS for patients with negative margins were 16.5 months (95% CI 12–23.5) and 58.2 months (95% CI 37.9–67.5), respectively, versus 4.8 (95% CI 2–15.2) and 47.2 months (95% CI 23.6–70.1), respectively, for those having positive margins.
