Although PD-L1 gene expression alone did not significantly correlate with poor survival in HCC patient datasets, coordinate expression of CDH1 and VIM showed worse overall survival (HR: 1.85, CI: 1.05~2.05, Log-Rank Equal Curves p = 0.02543) and recurrence-free survival (HR: 1.72, CI: 1.2~2.48, Log-Rank Equal Curves p = 0.003402) when combined with PD-L1 (Figures 12B,C). This evidence concerns the gene CDH1 and hepatocellular carcinoma.
