Dramatic results from a new cancer treatment trial are being called "a huge accomplishment—huge," and could mean a breakthrough in treating a common type of leukemia and potentially a range of other cancers. University of Pennsylvania scientists basically turned patients' T cells into leukemia-killing machines by modifying a virus so that it would cause the T cells to bind with and destroy leukemia cells. When the T cells were injected with the virus and then re-entered the patients, each one killed at least 1,000 cancer cells. Some experts believe other cancers—including blood, breast, and colon—could utilize the same type of treatment.
