SKA1 expression levels were significantly correlated with weight (Fig. 6A), age (Fig. 6B), T stage (Fig. 6C), N stage (Fig. 6D), M stage (Fig. 6E), tumor status (Fig. 6F), AFP levels (Fig. 6G), pathologic stages (Fig. 6H), histologic grade (Fig. 6I), OS (Fig. 6J), DSS (Fig. 6K), and PFI (Fig. 6L) of the HCC patients. The gene discussed is SKA1; the disease is hepatocellular carcinoma.
