Demographic and clinical features of patients included in the analysis, summarized overall and within histopathologic diagnosis subgroups.
The subgroup designated “other embryonal tumors” includes six patients with tumors formerly classified as CNS primitive neuro-ectodermal tumor (PNET) and one patient more recently diagnosed with embryonal tumor, not otherwise specified (NOS).
*,# Cause of death was disease recurrence or progression for deceased patients in the cohort except one patient with medulloblastoma (sequalae of treatment-related co-morbidities) and one patient with ATRT (complications of brainstem necrosis).
