Abstract Hepatocellular carcinoma (HCC) is characterized by high morbidity and mortality, and a low 5-year survival rate. Exploring the potential molecular mechanisms, finding diagnostic biomarkers with high sensitivity and specificity, and determining new therapeutic targets for HCC are urgently needed. Circular RNAs (circRNAs) have been found to play a key role in the occurrence and development of HCC, while exosomes play an important role in intercellular communication; thus, the combination of circRNAs and exosomes may have inestimable potential in early diagnosis and curative therapy. Previous studies have shown that exosomes can transfer circRNAs from normal or abnormal cells to surrounding or distant cells; thereafter, circRNAs influence target cells. This review summarizes the recent progress regarding the roles of exosomal circRNAs in the diagnosis, prognosis, occurrence and development and immune checkpoint inhibitor and tyrosine kinase inhibitor resistance of HCC to provide inspiration for further research.
