Abstract

Liver cancer, mainly hepatocellular carcinoma (HCC), remains a global health burden marked by poor prognosis with limited therapeutic efficacy, and high recurrence rates. HCC remains one of the most lethal malignancies worldwide, with limited therapeutic options and high resistance to conventional treatments. Despite low therapeutic efficacy, molecular heterogeneity, treatment resistance and high recurrence rate, hepatocellular carcinoma (HCC) is still a significant health problem worldwide. These restrictions have stimulated the research of focused methods for delivering therapeutic genetic payload into cancer cells. Bacteriophages have been gaining growing attention as an emerging delivery platform due to their genetic versatility, ease of engineering, ability to be surface modified and payload targeted. In this narrative review, the therapeutic potential of engineered bacteriophages in the context of HCC therapy is critically analyzed focusing on phage display-mediated tumor targeting, phage-mediated intracellular gene delivery, TRAIL gene delivery, and CRISPR/Cas-based therapeutic strategies. It has been previously noted in the literature that phage display can be used to attach tumor-targeting ligands to the surface of a phage, which may aid in the recognition of receptors at the tumor site and promote targeted delivery to the receptor. Therapeutic application is stunted by inefficient trafficking to the cytosol, endosomal degradation, immune recognition and clearance, vector stability, manufacturing scalability and regulatory issues. In conclusion, engineered bacteriophages are a promising and versatile tool for targeted gene delivery in HCC but more mechanistic, preclinical and translational research is needed to prove their therapeutic effectiveness and clinical usefulness for this purpose.
