Doctors: Cancer patients cured a decade after gene therapy

In 2010, doctors treated Doug Olson’s leukemia with an experimental gene therapy that transformed some of his blood cells into cancer killers. More than a decade later, there’s no sign of cancer in his body.
The treatment cured Olson and a second patient, according to the University of Pennsylvania doctors, who said it was the first time the therapy had been studied for so long.
“I’m doing great right now. I’m still very active. I was running half marathons until 2018,” said Olson, 75, who lives in Pleasanton, California. “This is a cure. And they don’t use the word lightly.”
His doctors describe the two cases in a study published Wednesday in the journal Nature. They say the two examples show the treatment, called CAR-T cell therapy, can attack cancer immediately, then stay inside the body for years and evolve there to keep the disease at bay. Such so-called “living drugs” are now used by thousands around the world to treat certain blood cancers.
