After participating in a global clinical trial, leaders at the Children’s Hospital Colorado (Children’s Colorado) Center for Cancer and Blood Disorders and the University of Colorado Cancer Center are celebrating results so transformative, they change the standard of care for treating most kids with B-cell acute lymphoblastic leukemia (B-ALL), the most common form of childhood cancer. The new therapy is less toxic than traditional chemotherapy, resulting in significantly fewer side effects like severe infections, mouth sores and bone marrow suppression, leading to improved quality of life for patients.
