Clinicopathological characteristics and surgical outcomes of sarcomatoid hepatocellular carcinoma

Figure 7 Kaplan-Meier curves of the estimated overall survival and recurrence-free survival of patients with sarcomatoid hepatocellular carcinoma stratified by the proportion of the sarcomatous component in the tumor. Sarcomatoid hepatocellular carcinoma patients were divided into three subgroups based on the proportion of the sarcomatous component in the tumor: (1) mixed subgroup ≤ 50% (n = 14); (2) mixed subgroup > 50% (n = 16); and (3) pure subgroup (n = 11). Kaplan-Meier analyses of (A) overall survival and (B) recurrence-free survival showed no differences among the three subgroups.
