American scientists reached a promising breakthrough in the fight against cancer when they announced what they described as a “vaccine” that was capable of destroying tumors and removing all of their traces. Researchers from Stanford University said that injecting two immune-stimulating agents directly into solid tumors in mice can eliminate all traces of cancer in the animals. After testing various combinations of molecules and antibodies, the researchers were able to reach the right combination that seemed the most effective in fighting cancer. "When we use these two agents together, we see the elimination of tumors all over the body," said Dr. Ronald Levy, the senior author of the study that was published in the Science Translational Medicine. "This approach bypasses the need to identify tumor-specific immune targets and doesnt require wholesale activation of the immune system or customization of a patients immune cells." One agent is currently already approved for use in humans; the other has been tested for human use in several unrelated clinical trials. A clinical trial was launched in January to test the effect of the treatment in patients with lymphoma, said the Stanford University Medical Center study.
