Summary
Radiosurgery effectively treats glomus jugulare tumors with low side effects. This study shows stable or reduced tumor size in patients with long-term follow-up, supporting its safety and efficacy.
Area of Science:
- Neurosurgery
- Radiation Oncology
Background:
- Glomus jugulare tumors are rare, and treatment options like radiosurgery have limited data.
- Previous studies on radiosurgery for these tumors often lack sufficient patient numbers and follow-up duration.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of Linac-based or CyberKnife radiosurgery for glomus jugulare tumors.
- To assess treatment outcomes and side effects in a larger patient cohort with extended follow-up.
Main Methods:
- Retrospective analysis of 21 glomus jugulare tumors treated with LINAC or CyberKnife radiosurgery.
- Doses ranged from 1400 cGy to 2700 cGy, with a median follow-up of 66 months (mean 60 months).
- Efficacy and post-treatment side effects were assessed via MRI and clinical evaluation.
Main Results:
- All 21 tumors remained stable or decreased in size on MRI.
- Neurological symptoms were stable in all patients.
- Low morbidity observed: two patients had transient tongue weakness/hearing loss, one had transient vocal cord paresis (history of prior radiotherapy).
Conclusions:
- Radiosurgery is a safe and effective treatment for glomus jugulare tumors.
- This study provides evidence from a larger patient group and longer follow-up, demonstrating low morbidity.
- Long-term tumor control and minimal side effects support radiosurgery as a viable therapeutic option.
