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). This evidence concerns the gene PPIA and hepatocellular carcinoma.
