The 20th International Symposium on Pediatric Neuro-Oncology was held June 13-15, 2022 in Hamburg, Germany. ISPNO is the major global meeting for the international community of professionals involved in the scientific research, diagnosis, treatment, and rehabilitation of kids and teens with brain and central nervous system cancers.

Doctors and researchers from the Morgan Adams Foundation Pediatric Brain Tumor Research Program had 39 abstracts selected for presentation at ISPNO 2022, among the most of any research group in the world. Of those, 11 were chosen for coveted and highly respected oral presentations during the three-day gathering.
