BACKGROUND: Data on clinical outcomes for base of skull (BOS) chordomas in the pediatric population is limited. We report patient outcomes after surgery and proton radiotherapy (PRT). METHODS: Pediatric patients with BOS chordomas were treated with PRT or combined proton/photon approach (proton-based; for most, 80% proton/20%photon) at a single institution from 1981-2021. Endpoints of interest were overall survival (OS), disease-specific survival (DSS), progression-free survival (PFS), freedom from local recurrence (LC), and freedom from distant failure (DC)...
