Abstract:
Oncolytic virotherapy is a novel antitumor therapy using genetically modified oncolytic viruses(OVs)that specifically replicate and induce lytic cell death in tumor cells. OVs directly induce tumor cell death and indirectly enhance the antitumor efficacy of chemoradiotherapy by suppressing cell survival signaling. Moreover, OVs activate antitumor immunity by inducing immunogenic cell death and enhance the antitumor effect of immune checkpoint inhibitors. OVs including herpes simplex virus and adenovirus have been widely developed for clinical application. This review focuses on the therapeutic potential of OVs in monotherapy and combination therapy with conventional cancer treatment and summarizes representative OVs that are in the phases of clinical trials.
Insights
Oncolytic viruses (OVs) offer a novel cancer treatment by selectively killing tumor cells. They enhance conventional therapies and boost immune responses, showing promise in clinical trials.
Area of Science:
- Oncology
- Virology
- Immunology
Background:
- Oncolytic virotherapy utilizes genetically modified oncolytic viruses (OVs) for cancer treatment.
- OVs selectively replicate in tumor cells, leading to cell lysis and death.
Purpose of the Study:
- To review the therapeutic potential of OVs in monotherapy and combination treatments.
- To summarize OVs currently in clinical trials for cancer treatment.
Main Methods:
- Review of existing literature on oncolytic virotherapy.
- Analysis of OVs' mechanisms of action.
- Summary of clinical trial data for representative OVs.
Main Results:
- OVs directly induce tumor cell death.
- OVs enhance chemoradiotherapy by suppressing survival signaling.
- OVs activate antitumor immunity via immunogenic cell death and improve immune checkpoint inhibitor efficacy.
Conclusions:
- Oncolytic virotherapy presents a promising approach for cancer treatment.
- OVs can be used as monotherapy or in combination with conventional treatments.
- Several OV therapies are advancing through clinical trials.

Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
