There's more news on the T-cell therapy work that I wrote about here and here . The New York Times has an update , and the news continues to be encouraging. So far about a dozen leukemia patients have been treated, and while not everyone has responded, there have been several dramatic remissions. Considering that every candidate for treatment so far has been at the edge of the grave (advanced resistant disease, multiple chemotherapy failures), there's definitely something here. This will have to be done patient-by-patient. But leukemia varies patient by patient , too, and effective therapies are probably going to have to get this granular (or more ). So be it. The challenges now are to find out how to make the success rates even higher, and how to deliver this sort of treatment to larger numbers of people. Challenge accepted , as they say. . .
