Yes actually chances are maybe it was a smaller tumor and caught earlier since the tonsil is visible - perhaps that why it was more effective on your hubby's tumo Maria. Since I'm a tongue cancer patient (oral tongue) I defer to charm and Dave but I too read that Erbitux does not do well with HPV+ cancers - actually is better for my type of cancer (non HPV ) - however one could also point out hat the primary treatment for my type of cancer - is actually surgery - then chemo and rads - so this begs the question - is Erbitux more effective on my type of cancer because the primary tumor is gone? Welcome - sorry you had to join our group - do have your dr look at the most recent studies on Erbitux and HPV related cancer take care... Ps cisplatin wasn't too bad for me either...
