Urgent need for prognostic markers for hepatocellular carcinoma in the light of genomic instability and non-coding RNA signatures.

Abstract

In this editorial, we comment on an original article by Duan et al. Despite advancements in the diagnosis and treatment of hepatocellular carcinoma (HCC), the identification of suitable prognostic factors remains challenging. In their paper, Duan et al identified long non-coding RNAs (LncRNAs) to quantify genomic instability (GI) by combining LncRNA expression and somatic mutation profiles. They confirmed that the GI-derived LncRNA signature (GI-LncSig) could be an independent prognostic factor with the area under the curve of 0.773. Furthermore, the authors stated that GI-LncSig may have a better predictive performance than TP53 mutation status alone. However, studies exploring genetic markers for predicting the prognosis of HCC are crucial for identifying therapeutic targets and enhancing diagnostic and treatment strategies to mitigate the global burden of liver cancer.
