A promising new cancer vaccine has shown the ability to ward off, and stop the return, of aggressive cancer cells. By adding a molecule called Diprovocim to a vaccine, researchers report being able to draw cancer-fighting cells to tumor sites in mice. It works in conjunction with other cancer-treatment therapies to stop some aggressive, and often deadly, forms of cancer, like melanoma. “This co-therapy produced a complete response — a curative response — in the treatment of melanoma,” said the study’s co-author, Professor Dr. Dale Boger of Scripps Research. The vaccine also prompts the immune system to produce the same…
