Head and Neck Stereotactic Body Radiation Therapy

Stereotactic body radiation therapy (SBRT) is an emerging technique for treatment of primary and recurrent head and neck cancers in patients unsuited for conventional management strategies. SBRT has demonstrated favourable responses and tolerable toxicity profiles for patients with unresectable primary disease or recurrent tumours. Severe toxicity risk remains, with carotid blowout syndrome a unique concern despite strategies to minimize risk.
