ABSTRACT=Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) remains a significant global health challenge due to its high prevalence and poor prognosis. Recent advances have revealed that non-coding RNAs (ncRNAs), including microRNAs, long ncRNAs, circular RNAs, and small nucleolar RNAs, play critical regulatory roles in HBV-induced oncogenesis. These ncRNAs modulate various cancer hallmarks and contribute to HCC progression. Notably, their stability, detectability in bodily fluids, and disease-specific expression patterns render these ncRNAs as highly promising diagnostic and prognostic biomarkers for HBV-HCC. Herein, we review the types and mechanisms of HBV-related ncRNAs, emphasizing their dual roles as oncogenes and tumor suppressors. Furthermore, we discuss their applicability as diagnostic markers and therapeutic targets and review recent directions in ncRNA-based approaches that aim to enhance patient treatment. Concerning these aspects, the present review aimed to provide an understanding of the complexity of ncRNAs in HBV-related HCC with the hope of directing future research and developments towards effective control of this complex malignancy known as HCC.
