Colleen, I think I was picked randomly for this trial...that is to say....my doctor has never mentioned the trial to me. I received a phone call from MDA and then they sent me all the info. I have had surgery to the throat above the voice box with laser at MD Anderson. I am fast approaching the one year mark this April, so time may be a factor also for the trial. To be honest, this trial is much more involved or invasive than I had originally thought. I'm really undecided at this time. Also, I still have to go in every two months for follow up with the surgeon on the treatment that I have had at MDA. Anyway, should I decide to go any further with the trial, I will be sure and let you know.
