Good point about our relatively small numbers reducing H&N specific studies. I was the one "postulating" here, since the article itself explictly lists 3 "unanswered questions", the second of which was
[quote]Second, fibrosis occurs in many different
organs and tissues after radiation. Is it equally reversible in all of them?[/quote]
The footnotes indicate studies from radiation for lung cancer
I admit it's a jump but I had found other studies that did involve head and neck cancer like this one:
Oral Pirfenidone in patients with chronic fibrosis resulting from radiotherapy:. It's too small to be significant with only 5 full participants,[quote] Four of the patients had been treated for head and neck cancer and one had been treated for Hodgkin's Disease. [/quote]
They used range of motion as one evaluative measure.
