EMBR-01. MOLECULAR AND CLINICAL HETEROGENEITY IN HISTOLOGICALLY-DIAGNOSED CNS-PNET PATIENTS PROSPECTIVELY TREATED AS A SINGLE ENTITY: A REPORT FROM THE CHILDREN’S ONCOLOGY GROUP ACNS0332 TRIAL

Children with high-risk medulloblastoma, supratentorial primitive neuroectodermal tumor (CNS-PNET) and pineoblastoma (PBLs) have poor survival and were enrolled in this prospective trial. However, subsequent molecular profiling uncovered diagnostic discrepancies not detectable at protocol inception. Outcomes for patients with CNS-PNET/PBL are reported here
