Scans info is at the bottom of the follow-up page. i have 2013 guidelines, and will try to copy in regards to scanning. It's not much. I can't copy, it's on page 83, follow-up guidelines, but this is what it says.

"Post-treatment baseline imaging of primary (and neck, if treated) recommend within 6 mo of treatment 3 (category 2b)
>further reimsging as indicated on signs/symptoms; not routinely recommended for asymptomatic patients."

Bottom of page 3 notation:

"For cancer of the oropharynx, hypopharynx, glottis pharynx, supra glottis larynx, nasopharyngeal: imaging is recommended for T3-4 or N2-3'disease only."

What I get from this is no post treatment scan for oral cancer, other types, and only certain cancers named above, if T3-4 or N2-3 disease only. I hope we can find more clarification, and appears some don't follow, which is a guideline, not a must do, but their recommendation are like the gold standard

Sorry Ed, I did not what I added was already in your post and missed it until I added mine.
