I am so sorry to hear what your wife is going through...
My father has melanoma. He was in remission for about eight years and in March it was discovered again and has been spreading quickly, now turning into carcinoma meningitis...from March through June he was on thalidimide and temador and had a horrible allergic reaction to the thalidimide and almost died in June from it.
The thalidimide caused him intense pain as he could not go to the bathroom. It also weakened his lungs nad he ended up with pneumonia from it and nearly died. Once the docs figured out what was going on he was taken off the thalidimide...
I hope your wife will not go through the same thing, but just thought you should know of some possible side effects to be aware of...
Best of luck to you and her..
Beth
