Disparity in Outcomes for Adolescent and Young Adult Patients Diagnosed With Pediatric Solid Tumors Across 4 Decades

For the most common pediatric extracranial solid tumors, AYA patients experience significantly worse OS compared with pediatric patients. Although improvements in therapy have led to gain in survival for pediatric patients, with the exception of osteosarcoma, AYA experienced no increase in survival over the study period. This investigation demonstrates the importance for further research in the AYA population.
