want it to be, it s a ferocious cell t. kills 1000 or more cancer cells, this one cell. so these leukemia patients were the ones tested, they were near death. they had two weeks to live. jon: they got this treatment, what happened? they re still alive now, two are totally disease-free, one has a reduction of the disease. the cancer dissipated within a matter of three, four weeks two, three weeks, pounds of cancer, disintegrating. the white blood cells essentially, as word described, became serial killerrings, they roamed through the blood stream and hunt down the cancers. in the genetic change, they have t cells that help the problem, so now you have the t cells descending, plus multiplying, so you put in 100t cells, you end up with 1000, and there are memory t cells that they remember and stick around for a year or two, and therefore, keep the cancer from recurring. jon: amazing stuff.
ground-breaking approach. it s being called the most significant advance in cancer research in decades. it s only been tried in three leukemia patients so far. all in advance stages of the disease with three other treatment options. the university of pennsylvania experiment created armies of what they call cereal killer cells. here s how they did it. blood was taken from each patient and the t-cells were removed. scientists inserted harmless version of hiv into those cells and millions of those cells were then injected back into the patienents. their intent was to use the patient s only blood cells to kill their cancer cells. it workeke they targeted cancer cells and not only destroyed existing cancer but new cancer as it emerged. this is an exciting study. it s exciting, because it takes principles that we ve been working on for decade, applies those to patients and produces truly meaningful results.
