Gamma Knife radiosurgery for glomus tumors: Long‐term results in a series of 30 patients

Abstract

Background Glomus tumors are rare and benign hypervascular tumors. Surgery represented the mainstay of their treatment, even if it has been associated with high morbidity and mortality rates. Recently, the treatment shifted to a multimodal approach and Gamma Knife radiosurgery represents one of the treatment options. Methods Authors retrospectively analyzed the clinical and radiological outcome of a series of patients who underwent Gamma Knife radiosurgery for glomus tumors. Results Thirty patients underwent Gamma Knife radiosurgery. Mean tumor volume was 7.69 cc (range 0.36‐24.6). Mean tumor margin dose was 16 Gy (range 13‐18). Median follow‐up was of 91 months (mean 90; range 11‐172). Overall clinical control rate was 100%; overall volumetric tumor control rate was 96.6%. Patients' and tumors' characteristics, treatment data, and outcome have been analyzed. Conclusion Gamma Knife radiosurgery represents a safe and effective treatment for glomus tumors. Longer follow‐up and larger cohort studies are needed to definitively outline the role of Gamma Knife radiosurgery for glomus tumors.

“…In addition, radiosurgical and multidisciplinary treatment options for other paragangliomas should be investigated as well and may be included in one large prospective trial. Considering our findings, similar long‐term experiences with GK, and the possibility to treat extracranial lesions, RRS may be suitable for the treatment of other head and neck paragangliomas than GJTs 59 …”
