Dosimetric advantages of stereotactic radiosurgery as a boost to adjuvant conventional radiotherapy in the setting of adenoid cystic carcinoma of the parotid with skull base invasion

摘要

Key Clinical Message This study highlights gamma knife stereotactic radiosurgery (GK‐SRS) as boost therapy in a patient with adenoid cystic carcinoma of the parotid involving the skull base and invasion of the facial nerve. Using GK‐SRS, dose to the brainstem and temporal lobe were reduced when compared to less conformal radiotherapy techniques.
