Summary:
Normal immune cells that were genetically altered to recognize and destroy cancer cells have successfully shrunk large tumors, scientists say. Two of 17 people with advanced melanoma—a deadly form of skin cancer—who underwent experimental treatment with the engineered immune cells saw their tumors shrivel.
The therapy has so far been applied only to melanoma patients. But the researchers are optimistic that their treatment can be used for many other types of cancer. The team has already engineered similar immune cells for more common tumors, such as breast, lung, and liver cancers.
The research appears in the September 1 issue of the journal Science.
