Sample SBRT treatment plan. Case example for an 88-year-old female with a T4aN0M0 squamous-cell carcinoma of the left buccal mucosa. She received 44 Gy in five fractions prescribed to the 80% isodose line over 10 elapsed days using the TrueBeam® RapidArc™ platform and three non-coplanar arcs. Dose–volume histogram shows the PTV (orange), oral cavity (pink), mandible (yellow), spinal cord (chartreuse), and parotids (right dark blue, left blue-green). She completed therapy with but grade 1 mucositis; she later developed grade II oral ulceration and trismus. She remained NED with complete metabolic response until dying from co-morbidities 20 months following SBRT.
