Hi - no someone else here posted it - here - i just read it. I think the context wasn't a higher recurrence rate - but rather the likeliness of a recurrence past 5 years being higher than non HPV h&n cancer. What I gathered from reading it was... Usually - after five years you're pretty safe - but the article suggested this was not so with HPV related oral cancer to me what I gathered from that was - possibly something due to the dormancy of HPV and possibly that the follow up for HPV related patients should be more long term. I don't go hunting down articles so I'm pretty sure it was referenced here.
