Leukemia is the most common form of cancer seen in children, affecting more than 3,000 children in the United States each year. While a diagnosis of this illness seems overwhelming, there is cause to be optimistic. Important scientific breakthroughs in the treatment of leukemia are being made and tested here at the University of Chicago. Our pediatric cancer care team has the extensive experience needed to provide young leukemia patients outstanding clinical care -- offering both the latest investigational therapies as well as established treatments for all types of leukemia. In fact, the University of Chicago Medicine Comer Children's Hospital was the first hospital in Chicago certified to offer CAR T-cell gene therapy for the treatment of acute lymphoblastic leukemia (ALL) in children and young adults.
