Could blood cells fight leukemia?

Doctors are taking a close look at a new gene therapy to battle leukemia in which a patient's own blood cells are engineered to hunt down cancer cells and destroy them.

So far, the University of Pennsylvania's experimental treatment has been used only in three patients, but the results seem clear so far.

One year later, two of those patients are cancer free and the third is improved.

The treatment involved men with advanced leukemia.

Scientists are preparing to try the same technique to try other types of cancer including pancreatic, ovarian, prostate, and brain cancer.
