Furthermore, the expression of BIRC5 (HR = 1.6, logrank P = 0.002) was correlated with decreased disease-free survival (DFS) for HCC patients, as was that of DLGAP5 (HR = 1.6, logrank P = 0.0033), DTL (HR = 1.6, logrank P = 0.0016), FEN1 (HR = 1.5, logrank P = 0.0075), KIAA0101 (HR = 1.6, logrank P = 0.0022), KIF4A (HR = 1.6, logrank P = 0.0011), MCM2 (HR = 1.6, logrank P = 0.0034), MKI67 (HR = 1.9, logrank P = 4.2e−05), and RFC4 (HR = 1.5, logrank P = 0.011) (Fig. 5). The gene discussed is PCLAF; the disease is hepatocellular carcinoma.
