Paula- My husband had a PET four days after his eight Erbitux treatment. We were also told at a follow up that the stuff keeps working for awhile after treatment is finished. The oncologist told us that he likes to get at least eight in before the do another scan. He will be stopping Neil's treatment because it did not work and hopefully Sloan can so something for him. I think he had this &*#$ disease for too long before diagnosis. He had three different doctors tell him it was a virus. A simple biopsy would have changed everything.
