Oncolytic virotherapy is an effective cancer treatment using a special virus, which is capable of finding and destroying malignant tumour cells in the body.
After being administered, the virus finds and infects malignant tumour cells in a process called oncotropism. The virus replicates itself in the cells of a malignant tumour destroying them in a process called oncolysis. Viruses not only destroy cancer cells but also activate the body’s natural immune system, which also targets the malignant cells.
How virotherapy works
The goal of virotherapy, not unlike that of radiation therapy and chemotherapy, is to destroy cancer cells, but virotherapy has several distinct advantages:
Virotherapy destroys tumour cells selectively without affecting the healthy cells of the body.
Virotherapy stimulates the body’s natural defence mechanisms by activating the immune system, which is often supressed by other treatment methods.
Virotherapy can be used against tumours that don’t respond well to radiation or chemotherapy, such as melanomas.
Virotherapy can be used at various stages throughout the treatment process: before or after surgery and also between radiation or chemotherapy treatments.
Virotherapy is recognised as a safe and efficient cancer treatment method.
