Immunotherapy could stop prostate cancer spreading, trial shows

Researchers say it is the first time this treatment has been shown to benefit some men

Men with otherwise untreatable prostate cancer could halt its spread and survive longer by undergoing immunotherapy treatment, a trial has shown.

More than a third of men with an advanced form of the cancer were still alive and one-in-10 had not had further growth after a year on the drug pembrolizumab, the study found.
