Thank you Brian and others for your suggestions. Since my last posting I have done some research on the web relating to interferon and vitamin A(accutane) and vitamin E. The concept is interesting as the purpose of all three is not to kill anything, like chemo, but to fortify one's immune system to protect itself better against recurrences of the primary tumor or secondary primary tumors.
The study seems to be concerned with a 3 year period wherein most recurrences apparently manifest themselves. The Phase II study allegedly , as I think I said, had 89 to 90% of the 45 participants with no recurrent tumors.
Before absolutely rejecting the program I intend to have a discussion with a couple of doctors including the one who is in charge of the protocol. However, my inclination, like yours Brian, is to pass on the study. It seems that I am on the cusp of feeling so much better and regaining my energy...and I just hate the idea of taking drugs that would cause me to feel ill again, at a time when I am not in need. Plus, it seems a little early to me to get involved in such a program when I am just getting over my original treatments and have such a long way to go regarding swallowing and eating solid food.

Thank you everyone....I really appreciate the input that any of you have.
