SBRT is feasible, with minimal grade ≥3 toxicity. The overall FFLP rate for all patients was 64.8%, comparable to rates with external beam radiotherapy. This shorter treatment course can be delivered without delay in adjuvant systemic therapy.

Single fraction radiosurgery was found to be clinically effective for the treatment of benign extramedullary spinal neoplasms. Although surgical extirpation remains the primary treatment option for most benign spinal tumors, radiosurgery was demonstrated to have short-term clinical benefits for the treatment of such lesions. The long-term efficacy of spinal radiosurgery for such tumors will be determined with longer follow-up periods. Its role in patients with neurofibromatosis will also be further defined with greater clinical experience.

SBRT is feasible and safe with minimal toxicities for treatment of rSCCHN patients with prior radiation therapy deemed to be poor candidates for re-irradiation by conventional means.
