Abstract:
The goal of oncolytic therapy is to exploit the innate ability of viruses to infect tumor cells, replicate in tumor cells, and produce selective oncolysis while sparing normal cells. Although the concept that viruses can be oncolytic is not new, it is only in the last three decades that efforts have been directed at genetically mutating viruses to specifically target characteristics of cancer cells. Several viruses have the potential to infect, replicate and lyse tumor cells, each taking advantage of different host cancer cell biology. This review will focus on the major viruses under current investigation for oncolytic therapy, the mechanism by which they specifically eradicate tumors, and the clinical strategies currently under investigation.
Insights
Oncolytic therapy uses viruses to selectively infect and destroy cancer cells, sparing healthy ones. Recent genetic engineering advances focus on optimizing these viruses for targeted tumor eradication and clinical application.
Area of Science:
- Virology
- Oncology
- Gene Therapy
Background:
- Oncolytic therapy leverages viruses' natural ability to infect and replicate within tumor cells.
- Genetic engineering has refined viruses to specifically target cancer cell characteristics over the past 30 years.
Purpose of the Study:
- To review major viruses investigated for oncolytic therapy.
- To elucidate the mechanisms of virus-mediated tumor eradication.
- To discuss current clinical strategies for oncolytic virus application.
Main Methods:
- Literature review of oncolytic viruses.
- Analysis of viral mechanisms targeting cancer cell biology.
- Examination of ongoing clinical trials and strategies.
Main Results:
- Several viruses show potential for selective tumor cell lysis.
- Different viruses exploit unique cancer cell vulnerabilities.
- Ongoing research focuses on optimizing viral targeting and efficacy.
Conclusions:
- Oncolytic viruses represent a promising therapeutic strategy in oncology.

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...
