The Children’s Oncology Group (COG) is the world’s largest pediatric cancer research network, uniting over 200 leading children’s hospitals, universities, and cancer centers across North America and internationally. As a collaborative clinical trials network, COG is dedicated to advancing the treatment and care of children and adolescents with cancer through coordinated research efforts. It conducts large-scale, multi-institutional clinical trials to develop new therapies, improve existing treatments, and increase survival rates while minimizing long-term side effects. By integrating laboratory research, clinical expertise, and patient-centered care, the COG network plays a pivotal role in setting the standard of care for most childhood cancers worldwide.
