Cloned cells cure man's skin cancer
An experimental cancer treatment has proved successful for one man. The patient had advanced skin cancer which had spread to his lungs and a lymph node. Previously, the cancer hadn't responded to other treatments. So what was this experimental treatment? Well, essentially the patient healed himself.In the study, patients' t-cells (white blood cells which promote immunity) were harvested and multiplied before being re-administered to the patient. After treatment, the patient went in to complete remission and remained in remission for two years.
Other patients in the study, who received smaller or greater amounts of cloned t-cells, either had no response to the treatment or only a limited response. Doctors aren't yet sure what variable caused this particular patient to respond so favorably. While further research is needed, this limited success gives doctors hope that they are heading in the right direction.
