Pediatric cancers are rarer than adult cancers, accounting for less than 1% of all oncological diagnoses. With such small patient populations, no single institution offers enough volume for reliable studies. COG researchers rely on coordinated, multi-institutional research to conduct trials that produce meaningful results.
Children’s Oncology Group (COG) unites more than 220 hospitals and over 13,500 members into a coordinated system with global reach. Advancing pediatric oncology research at this scale depends on bringing together patient populations, data, and expertise to support rigorous study. Within this framework, COG designs clinical trials and coordinates research, translating evidence into protocols that inform patient care across member institutions.
COG’s 220+ member institutions study and treat children and adolescents with cancer across a global network. These sites support patients from diagnosis through treatment and beyond, connecting families to clinical trials and specialized care closer to home.

COG supports researchers through a broad ecosystem of programs, tools, and shared resources designed to strengthen discovery, expand collaboration, and support pediatric cancer research beyond clinical trials alone.
The COG Biorepository, located at the Abigail Wexner Research Institute of Nationwide Children’s Hospital, is the largest pediatric cancer biorepository in the nation, containing over 2.5 million samples from children with more than 300 types of cancer.
Consistent with the policies of the National Institutes of Health (NIH), Children’s Oncology Group (COG) considers requests for individual patient data for use in research projects.
The COG-Endorsed Supportive Care Guidelines are rigorously developed, evidence-based standards for the prevention, monitoring, and management of complications caused by cancer or its treatment.
COG has developed several comprehensive resources for patients and families to use throughout their cancer journey. These resources include the COG Family Handbook and the accompanying COG KidsCare App, which provide reliable information about treatment, support, and follow-up care for children and young people with cancer.
