Among them, there was a significant difference of OS and RFS associated with 15 DElncRNAs (DUXAP8, DDX11-AS1, TMCO1-AS1, ZNF252P-AS1, AC091057.1, TM4SF19-AS1, HCG25, RP11-98G7.1, SNHG4, AC012313.8, TMCC1-AS1, ZFPM2-AS1, AL357079.1, LINC02709, and AC099850.4), suggesting they have remarkable prognostic value for HCC patients. Here, TMCO1 is linked to hepatocellular carcinoma.
