Head and Neck/Skull base cancers
There is considerable evidence that radiosurgical salvage of post-radiotherapy skull base and nasopharynx relapses provides durable local control in a high percentage of patients, with an apparently lower complication rate than is seen with conventional reirradiation techniques (31-36). The preponderance of published radiosurgery experience for recurrent head and neck lesions has been gained with Gamma Knife radiosurgery.
The frameless CyberKnife® design, multiple treatment capability, and virtually unlimited dose-coverage capability compared with Gamma Knife indicates a much larger spectrum of applicability to recurrent head and neck lesions with CyberKnife®.
