"In a potential breakthrough in cancer research, scientists at the University of
Pennsylvania have genetically engineered patients' T cells — a type of white
blood cell — to attack cancer cells in advanced cases of a common type of
leukemia.
Two of the three patients who received doses of the designer T cells in a clinical
trial have remained cancer-free for more than a year, the researchers said.
Experts not connected with the trial said the feat was important because it
suggested that T cells could be tweaked to kill a range of cancers, including ones
of the blood, breast and colon."
