Treatment of Chondrosarcoma at the Skull Base
Chondrosarcoma arising at the skull base represents a distinct anatomical subset that requires tailored local management. The proximity to critical neurovascular structures shapes both surgical strategy and the potential role of high-dose radiotherapy.
Clinical Scenario
This protocol applies to chondrosarcoma with a skull base location. High-dose radiotherapy combined with surgery can achieve high local control rates in this setting — reported at 80–90%. When surgery and particle beam radiotherapy are used together for skull base chondrosarcomas, local control rates of approximately 70–90% have been documented.
Treatment Approach
The protocol centres on a surgical intervention targeting adequate local clearance — specifically a form of wide surgical excision. The full sequencing, technical approach, and all associated management steps are detailed in the complete protocol.
