Pediatric Staging

The Commission on Cancer (CoC) of the American College of Surgeons requires childhood malignancies to be staged using either the AJCC system or the staging criteria of the pediatric clinical trial groups. The most common pediatric cooperative groups in the United States were the Children's Cancer Group (CCG) and the Pediatric Oncology Group (POG). Recently, CCG and POG merged and are now known as COG (Children's Oncology GroupExternal Website Policy).
