Short-term tumor control and acute toxicity after stereotactic radiosurgery for glomus jugulare tumors.
OBJECTIVE
Glomus jugulare tumors (GJT) have traditionally been treated by surgery or fractionated external beam radiation therapy (XRT). This study evaluates acute toxicity and short-term efficacy of single-fraction stereotactic radiosurgery (SRS) for the treatment of GJT.


METHODS
Eight patients (age range 28-74) with GJT underwent SRS (Brainlab linear accelerator) as primary treatment. A nominal dose of 15-16 Gy was prescribed.


RESULTS
After undergoing SRS, 7 of 8 patients (87.5%) reported complete resolution of presenting symptoms. Follow-up MRIs showed tumor stabilization in 100% of patients. Transient vertigo occurred in one patient. One patient suffered acute GI upset and transient lower cranial neuropathy.


CONCLUSIONS
Stereotactic radiosurgery is an effective alternative for patients with GJT in achieving tumor control and resolution of symptoms.
