How would you approach a recurrent, cutaneous SCC of the face with high-risk features s/p resection?

Definitive radiation therapy > 5 years ago. Positive margins, PNI of 0.1 mm. What volume would you cover? Dose/fractionation?

Answer from: Radiation Oncologist at Academic Institution

Likely previously treated with 6 MeV. Reirradiate the primary site and track nerves to skull base. Electively treat the regional nodes.
