Abstract:
Discovering a therapeutic that can counteract the aggressiveness of this disease's mechanism is crucial for improving survival rates for cancer patients and for better understanding the most different types of cancer. In recent years, using these viruses as an anticancer therapy has been thought to be successful. They mostly work by directly destroying cancer cells, activating the immune system to fight cancer, and expressing exogenous effector genes. For the treatment of tumors, oncolytic viruses (OVs), which can be modified to reproduce only in tumor tissues and lyse them while preserving the healthy non-neoplastic host cells and reinstating antitumor immunity which present a novel immunotherapeutic strategy. OVs can exist naturally or be created in a lab by altering existing viruses. These changes heralded the beginning of a new era of less harmful virus-based cancer therapy. We discuss three different types of oncolytic viruses that have already received regulatory approval to treat cancer as well as clinical research using oncolytic adenoviruses. The primary therapeutic applications, mechanism of action of oncolytic virus updates, future views of this therapy will be covered in this chapter.
Insights
Oncolytic viruses (OVs) offer a novel cancer therapy by selectively destroying tumor cells and stimulating anti-cancer immunity. This approach represents a promising advancement in improving cancer patient survival rates.
Area of Science:
- Oncology
- Virology
- Immunotherapy
Background:
- Cancer treatment requires therapies targeting aggressive disease mechanisms to improve patient survival.
- Oncolytic viruses (OVs) are emerging as a promising anticancer strategy.
- OVs can be naturally occurring or engineered to target tumor cells specifically.
Purpose of the Study:
- To explore the therapeutic potential of oncolytic viruses (OVs) in cancer treatment.
- To discuss the mechanisms by which OVs combat cancer.
- To review approved OV therapies and ongoing clinical research, particularly with adenoviruses.
Main Methods:
- Review of regulatory-approved oncolytic virus therapies.
- Discussion of clinical research involving oncolytic adenoviruses.
- Analysis of OV mechanisms, including direct tumor cell lysis, immune system activation, and gene expression.
Main Results:
- Oncolytic viruses (OVs) demonstrate efficacy through direct tumor destruction and immune system modulation.
- Engineered OVs can selectively replicate within tumor tissues, sparing healthy cells.
- Approved OV therapies and adenovirus research highlight their potential in cancer treatment.
Conclusions:
- Oncolytic viruses (OVs) represent a novel immunotherapeutic strategy for cancer treatment.
- The selective targeting and immune-stimulating properties of OVs offer a less harmful approach to cancer therapy.
- Further research into OVs, including adenoviruses, holds significant promise for future cancer treatment modalities.

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...
