Early promise, and caution, in measles virus cancer therapy

By Andrew M. Seaman NEW YORK (Reuters Health) - Mayo Clinic researchers stirred excitement on Thursday by saying they had treated a patient's blood cancer with a specially engineered measles virus, but even scientists involved in the work caution the response does not prove they have a cure. Many failed cancer drug trials involving hundreds or thousands of patients include results from \"outliers\" whose disease subsided inexplicably. “We have an enormous amount of work to do to determine if this is generalizable and how to best apply the approach to other cancer patients,\" said Dr. Stephen Russell, the report's lead author and a hematologist at the Mayo Clinic in Rochester, Minnesota. “We haven’t discovered a cure for cancer here.\" He and his colleagues write in the journal Mayo Clinic Proceedings that multiple myeloma‎ in a 49-year-old woman seemed to disappear after she received an extremely high-dose injection of a measles virus engineered to kill the cancer cells.
