Question about Pancreatic cancer Please help

I have a good friend suffering with pancreatic cancer. She just found out in October. She had surgery for the whipple, but they were unable to do this because of the artery. Since surgery she is worse than before. She has attacks everyday. Can hold very little food or drink. Lost over 33 pounds already. She is finishing Rads at this time and will then go on to chemo. It hard for her to fight this when she is this sick. The doctors don't seem to have an answer or a cure for her throwing up all the time. Does anyone have any advice for my friend. They say the cancer has not spread, its just in the pancreatis.
