Abstract (original English)

Cancer is a major challenge to global health, and its incidence rate and mortality are expected to continue to rise in the coming decades. Traditional treatment methods such as surgery, radiotherapy, and chemotherapy have limitations, which has prompted people to explore new treatment strategies. As a promising therapeutic approach, oncolytic viruses can selectively target and lyse tumor cells while avoiding damage to normal tissues. This article systematically reviews the mechanisms by which oncolytic viruses induce various forms of cell death, including apoptosis, autophagy, pyroptosis, necroptosis, and ferroptosis. We explored the direct killing effect of oncolytic viruses and their ability to activate local and systemic antitumor immunity, with a focus on the latest developments in the clinical application of oncolytic viruses, such as the development of novel recombinant viruses. In addition, we also analyzed strategies to enhance the efficacy of oncolytic viruses through gene modification, combination therapy, and targeted delivery systems. A deeper understanding of the multiple mechanisms of action of oncolytic viruses can help us develop more effective and personalized cancer treatment plans. Future research should focus on optimizing oncolytic viruses to overcome tumor drug resistance and improve patient prognosis, making them an important pillar of cancer treatment.
