Abstract

Cancer has caused a tremendous burden in developing countries. Oncolytic virus (OV) therapy is an emerging modality with the potential to be a single or combination agent with radiation therapy (RT). Following entry of OV to the cell, OV will replicate and assemble before exiting from tumor cells. Construction of OV can be done by modifying the capsid, genome, and chemical material of viruses. Irradiation will induce double-strand breaks, and further integration of OV with DNA damage response pathway will interact with the MRE11-Rad50-Nbs1 complex to regulate the mobilization of E4 open reading frame 6, protein phosphatase 2A, poly(ADP-ribose) polymerase, apoptosis-inducing factor, and topoisomerase-IIβ-binding protein 1. Degradation of DNA-dependent protein kinase catalytic subunits via human simplex virus-1-infected cell polypeptide 0 will inhibit DNA repair. OV and RT have a synergistic interaction to cause viral oncolysis and upregulation of immune response. In the clinical setting, most studies have demonstrated that OV is a safe treatment with less toxicity. Moreover, OV + RT resulted in longer median survival (62.4 vs. 37.7 weeks) in malignant glioma.
