Many cancer patients starve themselves to death. I believe the condition is called "cachexia". Like Gail and Joanna I am surprised that thr docs aren't on top of this and that includes the depression issue which is a well known side effect. Typically Cisplatin is given in three increments during radiation. I don't think I would have lived through all three treatments that I had (they shortened it to 2) let alone 6! You have also get his doctors to order a consult with a nutritionist. In spite of his I.Q., he is at a point where his logic is seriously flawed and quite understandibly so. I did it PEGless as well but it was VERY difficult and I had to force myself to eat inspite of tremendous pain and many other side effects. I think that I surprised some doctors that I survived at all.

I would not only look for an admission, I would demand it, the situation is well out of control.
