question: my sister 47 had gallbladder stage 2 cancer, had surgery done and after 1 year she got liver metasis, she is now at the hospital, cause had an infection of the bile, a stunt was placed to drain infection, she had received 2 types of chemo for 3 months, but did not workNow taking Tarceva and should start pallitive chemo once she is better stage.  My concern is that she is retaining fluid her belly is swollen, her ankles pratically all over.  Is there anything that can be done, what does this mean for her life.She is not taking any other medications.  She is strong and she is positive on all this.  Would she be a candidate for liver transplant.TksVicky
