The Childhood Solid Tumor Network (CSTN) offers the world's largest and most comprehensive collection of scientific resources for researchers studying pediatric solid tumors and related biology.

By freely sharing unique tools with no obligation to collaborate, we aim to promote global discovery and new treatments for pediatric patients with poorly understood and difficult-to-treat solid tumors.

About the Childhood Solid Tumor Network

Childhood solid tumors are often difficult to study and treat because they are rare and originate in the complex biological context of developing organs. CSTN was established to disseminate resources and data that have been developed at St. Jude Children’s Research Hospital, with the aim of stimulating basic research and speeding translation to the clinic.

The effort was launched in 2013 by Howard Hughes Medical Institute investigator Michael Dyer, PhD, of St. Jude Developmental Neurobiology, and Alberto Pappo, MD, of St. Jude Oncology.
