Description:
A large group
          of researchers, hospitals, and cancer centers that get
          support from the National Cancer Institute (NCI) to study
          childhood cancers. The main goal of the
          COG is to conduct clinical
          trials that test new ways to prevent, diagnose, and treat
          cancer in children and adolescents. These clinical trials
          also include supportive care and childhood cancer
          survivorship studies. The COG
          has hospitals and cancer centers in the United States,
          Canada, Europe, Australia, and New Zealand. It is part of
          the National Clinical Trials Network
          (NCTN). Also called Children’s Oncology Group.
