Hey Maria -
Glad to hear he's off the Cisplatin. It's so harsh. My husband has had problems with the neuropathy as well, just limited to his hands and feet though. Acupuncture helps with the neuropathy and so does Capsaicin creme - or a diabetic aid creme that has capsaicin as the main active ingredient. We use it on my husband 3 - 4 times per day (or less), and he is starting to getting some relief from the neuropathy. You need to apply it cautiously to be sure he doesn't have a reaction to it. If he has numbness, he might not be able to tell if its creating a burning sensation, but if you apply it sparingly and just watch to be sure he doesn't develop redness it may offer him some relief.
My husband has read up on the treatment you are referring to and he said most of what he has read has been positive. (He had studied medicine for a number years and understands this stuff much better than I) MD Anderson is an excellent facility and would have been our next choice for a treatment center, and still remains an alternative should it become necessary.
You should also check out another site, while you're reading, www.lifeovercancer.com amazing stories of people that have overcome stage III and IV cancer. The facility is wonderful, and combines healing the body as a whole (which is so important) with chemo and alternative therapy.
My thoughts and prayers remain with you and your family.
Karen
