High EXO1 expression levels were associated with unfavorable OS in the HCC patients of different races, especially Asians (HR = 4.15, p < 0.001), clinical T2, T3, and T4 stages (HR = 1.70, p = 0.016), clinical pathologic stages, tumor status (HR = 2.19, p = 0.001), and clinical histologic grades, G1 and G2 (HR = 1.82, p = 0.01) (Figure 10A), and DSS (Figure 10B). Here, EXO1 is linked to hepatocellular carcinoma.
