My 65 y.O. Father went to er with chest pain in july (he is recipient of investigational heart wrap procedure & thought it was related). Nothing was found (x-rays, labs, us). In september he went back with pain in upper abdomin. Ct showed a 8 cm mass on liver. It was biopsied & came back as malignant, undifferentiated "something" which the Dr. Advised meant that it probably originated somewhere else. He had an ercp, colonoscopy, etc & nothing was found so they did additional tests on the biopsy slides and said it was melanoma that had metastized to the liver. He saw an oncologist down at shands gainesville (u of fla - where he had heart wrap) that did a pet scan that showed no mets anywhere other than liver & wanted to start chemo with dtic. He elected to have chemo at home (in jax, fl) so was referred to local md. Local guy says not melanoma but cancer that probably originated in the bile duct. Both physicians very convincing -- who do we believe???? Local md has started him on chemo & says with treatment, life expectancy of 9 to 12 months... If it's really melanoma, won't traditional chemo not affect? If really bile duct cancer what are other options. He was told the tumor is affecting about 80% of the right side of the liver but not affecting any part of the left side. Any help will be greatly appreciated!!!!!
