The DFS-related multivariate analysis results showed that the expression of 39 genes (ALDOB, APOB, AURKB, C5, CCNF, CD4, CENPJ, CETP, COL18A1, CPT2, DAND5, DNASE1, EBPL, F7, FLT3, G6PD, GNMT, ITGB2, KLRK1, KNG1, LMOD1, NEK2, PCLAF, PER1, PKM, POU2F1, PPAT, PPIA, PRF1, PTPN6, RUNX3, SELP, SLCO1B1, SPPL2A, STAT5A, TCF21, TRPV1, TUSC1, and TYMS) was significantly associated with DFS in HCC patients (p < 0.05, Table 1). Here, POU2F1 is linked to hepatocellular carcinoma.
