Man's cancer vanished after he was injected with weakened herpes virus - Insider

A new cancer therapy that uses a modified herpes virus to attack tumor cells showed promise in early clinical trials abroad.

Other patients in the trial saw their tumors shrink, although the majority did not have a significant change: three out of nine patients who were given the trial drug alone, and seven of 30 who received a combined treatment, appeared to benefit from the experimental therapy.

The drug works similarly to T-Vec, a viral therapy that was approved to treat advanced skin cancer in 2015.

These viral therapies hold great promise for treating multiple forms of cancer, with "truly impressive" treatment responses observed in patients with advanced esophageal cancer and a rare type of eye cancer, Harrington told the BBC.
