@woodsy1 My husband had the tonsil with tumor removed but cancer had spread to nearby neck lymph node,right side for both. We weren't told size, just that as tumor was removed he was accepted into the clinical trial. His cancer was hpv +16. He did fine until last radiation as he had both chemo and radiation for 2 days. They gave him cisplatin 100mg split over 2 days twice, both split over 2 days. We say chemo dr and apparently for 3 weeks he is in the chemo cycle. Watch for low sugar symptoms, my husband had 2 bouts of double vision, gave him 4 glucose tablets and this helped, he isn't diabetic. So in all he had 15 radiation treatments and 2 chemo sessions with lots of hydration infusions. If I can answer any more questions please let me know. The worst symptom he had was loss of taste,he's still not eating a whole lot but trying different things. His last treatment was 12/31/25.
