Modified Form of HIV Helps Seven Year-Old Fight Leukemia
Description:Seven-year-old Emma Whitehead was near death from leukemia last spring. Now her doctors say an experimental treatment at the Children's Hospital of Philadelphia is credited with saving her life. The experimental treatment called T-cell immunotherapy, used a disabled form of the HIV virus to reprogram Emma's immune system genetically to eliminate the cancer cells. Emma's oncologist Doctor Stephan Grubb said the lymphoblastic leukemia that almost took Emma's life is now completely in remission.(3:00)
