Role of radiosurgery in the management of glomus tumors.
Glomus tumors are benign slow-growing hypervascular neoplasms. The role of radiosurgery for the treatment of these tumors has increased. The purpose of this study was to show our experience with glomus tumors and to analyze different prognostic factors.



Data from 39 adult patients were retrospectively analyzed. All of them underwent head frame stereotactic radiosurgery with linear accelerator (LINAC). Tumor and symptomatic control were calculated using the Kaplan-Meier method. Bivariate statistical analyses were performed to examine different prognostic factors.



The median follow-up was 71 months. The radiological local and symptomatic control was achieved in 37 patients (94.8%) and 29 patients (74.3%), respectively. Toxicity was detected in 4 patients (10%). In the bivariate analysis, dose coverage and maximum dose were associated with tumor control with an odds ratio (OR) of 5.29 (p = .041) and 2.67 (p = .056), respectively.



Stereotactic radiosurgery is a safe and efficient treatment for glomus tumors that is associated with high probability of radiological and symptomatic control and low incidence of morbidity. © 2015 Wiley Periodicals, Inc. Head Neck 38: E798-E804, 2016.
