There is a growing body of literature using SBRT in the re-irradiation setting for locally recurrent H&N tumors. Doses vary, with best results/lowest toxicity ≥35 Gy in five fractions, given on alternating days. Toxicity rates of SBRT appear to be lower than with conventional techniques; however severe acute and late toxicities remain a challenge.
