This page addresses the management of chordoma that has recurred as an isolated local-regional relapse specifically at the skull base — a clinically distinct situation with its own surgical and palliative considerations.

Skull-base isolated local-regional relapse in chordoma presents particular surgical challenges. R1 resection is the recommended goal of surgical treatment in this setting — reducing tumour volume to enhance the effectiveness of subsequent radiotherapy.

Management focuses on palliative loco-regional strategies and, where appropriate, systemic therapy. Several loco-regional modalities are employed, with the selection tailored to tumour volume, location, and individual patient factors.

The full regimen — including the complete set of options, preferred sequences, and specific agents — is available in the structured protocol below.

Primary goal: Pain control / reduction of pain

Skull-base isolated local-regional relapse.

For skull-base tumors R1 resection should be the goal of surgical treatment in all cases, in order to reduce tumor volume and increase the effectiveness of subsequent RT (V-A).

'Salvage palliative/supportive treatment choices' include debulking surgery, low-dose RT, stereotactic body RT (SBRT), including radiosurgery to small volume, radiofrequency ablation (RFA) and other loco-regional approaches (i.e. cryotherapy), systemic therapy, PC and observation.

Retrospective data suggest that cryoablation and RFA can be safe and useful palliative treatments in recurrent extracranial chordomas with a benefit in pain control.
