Waiting is the worst! I had to wait for the surgical pathology a few times to see the course of further treatment, but usually they had an idea or was told from the start the treatment plan.

Not sure where the suspicious SUV is in the pharynx as it consists of the Nasopharynx, Oropharynx and Largynopharynx. Are they doing non invasive surgery? There are also several types of neck dissections. Mainly selective, modified radical and radical with some different variances with the lymph chain levels, and structures removed.

I've had the SUV, Standardized Uptake Value, on some PET/CT's that were less than 2.00, which were found positive in a FNAB, but anything over 2 should be considered suspicious, ruled out as cancer, and none are used solely as a diagnosis of such.

As far as SBRT, Stereotactic Body Radiation Therapy, it's not new. They use it for some head and neck cancers, George Harrison had it in 2001, and some dedicated brand named systems are better known as Cyberknife, Robotic Radiosurgery, and non dedicated systems, like Varian, are capable of performing conventional radiotherapy, IMRT, and SBRT. Their all external beam radiation though.

The only thing I can suggest is a second opinion, if you want, staying/eating healthy, doing light exercise, keeping busy with hobbies, reading, music, etc. while waiting for surgery. Good luck.
