A therapy that sneaks cancer-targeting viruses into tumor tissue by hiding them in white blood cells eliminated prostate cancer in mice, according to researchers at the University of Sheffield in England. In the experiment, mice were injected with the cells two days after chemotherapy, when white blood cells are swarming to repair tissue damaged by chemotherapy. In the new therapeutic approach, the virus replicates, rapidly resulting in tumor eradication in all the treated mice. Experts called the work "groundbreaking" but noted the approach may not work in humans.
