Figure 4

Kaplan-Meier curve of disease-free survival (DFS) () and overall survival (OS) () stratified by extension of liver resection. Median DFS and OS for patients undergoing major hepatectomies were 14 months (95% CI 6–21.5) and 37.9 months (95% CI 14–62.7), respectively, versus 18 (95% CI 10.4–27.8) and 65.7 months (95% CI 43.7–NE), respectively, for those undergoing a minor/wedge resections versus 5 (95% CI 1.5–18) and 62.6 months (95% CI 12.4–119.3), respectively, for patients treated with radiofrequency ablation. Major = major hepatectomies; minor/wedge = minor hepatic resection/wedge resection; RF = radiofrequency ablation; NE = not evaluable.
