Melanoma kills thousands of people every year

研究人员称，一种引起感冒疱疹的病毒在经过转变后很有可能对治愈皮肤癌有所帮助。这种变体病毒对正常细胞是无害的，但当其被注射进肿瘤后，它会释放出一种抗癌物质。以下是 Michelle Roberts 的报道：

Although it's not yet being licenced, doctor are excited about the very real prospect of a brand new type of treatment for advanced melanoma. T-Vec is unique, using a virus to enter and kill cancerous cells.

This latest study in the Journal of Clinical Oncology is the largest ever randomised trial of an anti-cancer virus. It involved 436 patients with inoperable tumours and showed that T-Vec injections could lengthen survival by years, but only for some.

Researchers now want to do more studies to help better identify which patients might benefit from the treatment and whether it should be used alongside other melanoma drugs that are already approved.
