Clinicopathological characteristics and surgical outcomes of sarcomatoid hepatocellular carcinoma

Figure 4 Kaplan-Meier curves of the estimated overall survival and recurrence-free survival of patients with sarcomatoid or high-grade hepatocellular carcinoma stratified by American Joint Committee on Cancer stage. A: Sarcomatoid hepatocellular carcinoma (HCC) is associated with worse overall survival (OS) in patients with American Joint Committee on Cancer (AJCC) stage I-II disease (log-rank P < 0.0001); B: Sarcomatoid HCC is associated with worse recurrence-free survival (RFS) in patients with AJCC stage I-II disease (log-rank P = 0.0004); C: Sarcomatoid HCC is associated with worse OS in patients with AJCC stage III-IV disease (log-rank P = 0.0004); D: Sarcomatoid HCC is associated with worse RFS in patients with AJCC stage III-IV disease (log-rank P = 0.0004).
