Univariable Cox regression analysis of the DElncRNAs in the ceRNA network revealed that 19 lncRNAs (AC016747.3, AC024560.3, AC092171.4, BACE1−AS, CIDECP, CTD−2510F5.4, DSTNP2, LINC00294, NRAV, PDIA3P1, PPIAP22, PSMD5−AS1, RP11−147L13.13, RP11−385F5.5, RP11−546D6.3, SNHG1, SNHG3, STAG3L4, and TPM3P9) are related to the prognosis of patients with HCC. This evidence concerns the gene PDIA3P1 and hepatocellular carcinoma.
