EWSR1 and hepatocellular carcinoma: Kaplan-Meier analyses indicated that overexpression of EWSR1 was associated with poor OS (P < 0.01, Figure 2(a,b)) in the TCGA dataset, and the DFS and OS curve of our cohort also showed that HCC patients with low EWSR1 expression had better clinical outcomes than those with high expression (P < 0.01, Figure 2(c,d)).
