Oncolytic
The term oncolytic refers to the ability to selectively destroy cancer cells.
It is most commonly used in the context of:
Oncolytic viruses
Oncolytic viruses are viruses that are engineered or naturally selected to:
Infect and replicate within tumor cells
Cause lysis (destruction) of those cells
Spare normal, healthy cells as much as possible
Examples include:
Talimogene laherparepvec (T-VEC) – a modified herpes simplex virus, approved for melanoma
Reovirus, adenovirus, vaccinia, and measles virus – under clinical investigation for various cancers
Oncolytic therapy
This refers to therapeutic approaches that use oncolytic viruses to:
Directly kill cancer cells
Stimulate the immune system to recognize and attack tumors
Be combined with other treatments such as immunotherapy or chemotherapy
Advantages
Oncolytic virotherapy is an emerging and promising area of cancer treatment, especially in clinical research and personalized medicine.
