ABSTRACT
Background The liver plays host to both primary and secondary tumors. However, the scope of this chapter is to concentrate on those tumors which have their primary origin within the liver. These tumors are unusual in that they can be limited to a single organ, grow, metastasize, and then kill their host, still within their organ of origin. In addition, unlike most other tumors, the host organ is normally sick before the tumor develops, and successful treatment of the tumor can be followed by death from liver failure. It is also unusual in that the radionuclide therapies that have been developed are local in nature.
