Clinicopathological characteristics and surgical outcomes of sarcomatoid hepatocellular carcinoma

Figure 5 Kaplan-Meier curves of the estimated overall survival and recurrence-free survival of patients with sarcomatoid or high-grade hepatocellular carcinoma stratified by differentiation grade of the carcinomatous component. A: Sarcomatoid hepatocellular carcinoma (HCC) is associated with worse overall survival (OS) in patients with Edmondson-Steiner (ES) grade III differentiation (log-rank P < 0.0001); B: Sarcomatoid HCC is associated with worse recurrence-free survival (RFS) in patients with ES grade III differentiation (log-rank P < 0.0001); C: Sarcomatoid HCC is associated with worse OS in patients with ES grade IV differentiation (log-rank P = 0.0048); D: Sarcomatoid HCC is associated with worse RFS in patients with ES grade IV differentiation (log-rank P = 0.0005).
