Dad is back in the hospital...not sure if it is his liver metastasis or his gall badder acting up.  He did have chemo Monday, but they changed the drugs to second line therapy--because the spots on his lung and liver had advanced while he was getting his brain radiation, so they decided the Cisplat was not being very effective.  Since he had a rough past couple days, I am not sure of the plan for future treatments.  Quality of life has become a focus now...
