About Us

The Children’s Oncology Group (COG) a member of the National Cancer Institute (NCI) National Clinical Trials Network (NCTN), is the world’s largest organization devoted exclusively to childhood and adolescent cancer research. COG unites over 12,000 experts in childhood cancer at more than 220 leading children’s hospitals, universities, and cancer centers across the United States, Canada, Australia, New Zealand, and Saudi Arabia in the fight against childhood cancer.

Today, more than 80% of the 15,000 children and adolescents diagnosed with cancer each year in the United States are cared for at COG member institutions. Research performed by COG institutions over the past 50 years has transformed childhood cancer from a virtually incurable disease to one with a combined 5-year survival rate of 86%. COG’s mission is to improve the cure rate and outcomes for all children with cancer.

COG has more than 100 active clinical trials open at any given time. There are approximately 12,000 patients registered on COG trials each year. These trials include front-line treatment for many types of childhood cancers, studies aimed at determining the underlying biology of these diseases, and trials involving new and emerging treatments, supportive care, and survivorship.

COG is chaired by Douglas S. Hawkins, Seattle Children's Hospital. Lia Gore, MD, Children's Hospital Colorado, serves as the vice chair.
