The International Pediatric Adrenocortical Tumor Registry initiative: contributions to clinical, biological, and treatment advances in pediatric adrenocortical tumors.

Adrenocortical tumor (ACT), a rare tumor with a heterogeneous presentation, incompletely understood pathogenesis, and generally poor prognosis, occurs in 1-2 people per million and is even more uncommon in the pediatric population. Such rare cancers are a challenge to clinical practice. Exchange of experience, information, and data on rare cancers is lacking, and outcomes for these rare cancers could be improved through the establishment of an international registry. The establishment of the International Pediatric Adrenocortical Tumor Registry (IPACTR) in 1990 by the St. Jude Children's Research Hospital International Outreach Program offered a new opportunity to collect clinical and laboratory features, treatment practices, and outcome data for children with ACT, research this disease, and systematically investigate how to improve patient outcomes. These efforts will improve the availability of information for both patients and the medical community.
