Role of radiation therapy in glomus tumor

Since 1964, we have reported twenty-five cases of glomus tumors. Given the evolution of modern surgical technique, we have divided our cases into two groups. The first group includes patients seen from 1964 to 1975: sixteen cases, of whom eleven underwent successful radiotherapy, with a follow-up after ten years. Since 1975 we have adhered to the following therapeutic principles: We have given radiotherapy (5000 rads in twenty-eight days) to patients older than 65 with glomus tumors that had invaded posterior and medial cranial fossa and carotid canal (type C-D, according to Fisch). We have operated on patients with glomus tumors type A-B. Patients treated since 1975 (N = 9) are in the second group.
