I think maybe we had this conversation before, Glenn, but even if we did it seems worth saying that the research that shows chemo adds 10-15% effectiveness to radiation adds 10-15% more to local/regional control. That same research also shows no effect of that particular chemo (concurrent cisplatin) on the likelihood of metastatic cancer. So even if you had the chemo, Glenn, it may not have been effective in the way you would have liked. I just say this to try to keep the picture of the advantages of chemo a little more balanced--and also because it is still not receommended protocol for treatment for many early stage oral cancers.
