Patients often ask what oncolytic viruses are and how they work in fighting cancer. Below, we present some of the most important facts and conclusions from independent studies conducted by doctors & scientists, as well as from the clinic's website. It turns out that the anti-cancer properties of oncolytic viruses are being actively studied in many research institutions around the world.. I encourage you to read the attached articles (links in comments).
Information from the clinic's website:
Viruses are known to cause many diseases. A lesser-known fact is that some viruses can be used in cancer treatment. Over 100 years ago, doctors first observed that patients were cured of cancer after contracting an infectious disease. Systematic research has shown that there are viruses that selectively attack cancer cells. These are called oncolytic viruses. In October 2015, the first oncolytic virus was approved in the USA, and later in Europe and Australia in 2016, for the treatment of malignant melanoma.
Cancer cells cannot defend themselves against viruses
Cancer cells are particularly susceptible to viral attacks because, unlike healthy cells, they cannot produce enough interferon to defend themselves. Therefore, viruses can freely replicate within cancer cells. This, in turn, alerts the immune system, leading to an immune response against cancer cells throughout the body. Healthy cells prevent virus replication by producing interferon and are therefore not damaged, making virus treatment virtually free of side effects.
Newcastle Disease Virus
The Newcastle Disease Virus, used in cancer treatment at IOZK, is one such oncolytic virus. It has been used for decades and has been particularly well-studied for its effectiveness in fighting cancer.
Conclusion from the article by Iranian scientists published in 2023 (link in the comments):
This review highlights the growing role of oncolytic virotherapy using the Newcastle Disease Virus (NDV) in cancer treatment, emphasizing its ability to selectively replicate in cancer cells, induce immunogenic cell death, and influence signaling pathways related to oncogenesis, supported by numerous in vivo and in vitro studies.
Numerous clinical studies on NDV have been conducted, evaluating its safety, efficacy, and application in complex cancer treatment strategies. Despite these advances, many challenges remain, such as the mechanisms by which cancer cells evade the immune response, tumor heterogeneity, and tailoring treatment options to the specific characteristics of the tumor. Moreover, NDV-based therapies require careful consideration of regulatory and commercialization issues to become widely accessible and accepted.
The potential of NDV in cancer therapy is significant. The combination of oncolytic virotherapy, immunogen-induced cell death, and modification of oncogenesis-related signaling pathways forms the core of this innovative approach. However, it should be remembered that the clinical implementation of NDV-based oncolytic virotherapy may encounter challenges such as optimizing delivery methods, counteracting potential side effects, and ensuring safety and efficacy in humans, requiring further research and development. NDV-based therapies are expected to revolutionize cancer treatment, improve patient outcomes, and enable more personalized and precise cancer therapies through continued research, collaboration, and overcoming future challenges.
Conclusion from the article from dr Greg Delgolffe of the University of Pittsburgh School of Medicine from October 2023 (link in comments):
One of the most important findings in cancer research in the past two decades is that tumors can create force field-like protection against the immune system. A new study has identified a way to break through that force field to improve cancer treatment, by taking advantage of a virus that can specifically infect cancer cells.
One oncolytic virus, an immunotherapy called T-VEC, has been approved by the Food and Drug Administration (FDA) for the treatment of metastatic melanoma. Oncolytic virus therapies for additional types of cancer have yet to be approved, although several are being tested in clinical trials.
In the new study, funded in part by NCI, Greg Delgoffe, Ph.D., of the University of Pittsburgh School of Medicine, and his colleagues created a modified oncolytic virus that can transport the genetic instructions for a potent cancer treatment directly into cancer cells.
To use the immune system to kill cancer, as is the case with immune checkpoint inhibitors, you need to block immune-suppressing signals, Dr. Delgoffe emphasized. This new oncolytic virus approach is a way to “turn the tide,” he said, and “convert a resistant tumor into a sensitive one.”
