Would you electively cover any nerves for adenoid cystic carcinoma of the tonsil with positive PNI on pathology?

Absolutely YES. With positive PNI, I don't think it's just "elective", it should probably be a "must". With the capability to do precision-oriented irradiation technique via IMRT/SRT nowadays, I think target volume coverage along a major branch of a relevant cranial nerve is relatively achievable while incurring acceptable risk of latent normal tissue damage if you keep the dose to be around LQED2 of 50 Gy (i.e. for subclinical disease). One should keep in mind that the involved cranial nerve it...

Yes, V2.
