'Amazing' therapy wipes out leukemia in study - Yahoo!

Scientists are reporting the first clear success with a new approach for treating leukemia — turning the patients' own blood cells into assassins that hunt and destroy their cancer cells.

They've only done it in three patients so far, but the results were striking: Two appear cancer-free up to a year after treatment, and the third patient is improved but still has some cancer. Scientists are already preparing to try the same gene therapy technique for other kinds of cancer.
