Skin cancer is treated with the cold sore virus. Researchers claim that a genetically modified form of a virus that typically causes cold sores holds great potential for the treatment of skin cancer.
The modified herpes virus doesn’t hurt healthy cells, but it replicates and releases chemicals that fight cancer when it is injected into tumors. The medication may extend survival by years, according to trial findings published in the Journal of Clinical Oncology, but only for select melanoma patients. The procedure is not yet approved. Although there are already similar “immunotherapy” melanoma treatments available in the US and Europe, researchers think T-Vec would be a welcome complement to them. The most recent study, which included 436 patients from 64 centers, is the largest randomized trial of an anti-cancer virus yet conducted.
