PULLMAN, Wash.—Washington State University’s College of Veterinary Medicine is administering a first-of-its-kind cancer treatment today to an 8 year-old, golden retriever named “Cassie.”  The drug is known by the generic name Samarium-153-EDTMP or by the brand name of Quadramet.  It works by attaching itself to areas where bone is rapidly growing.  Because a radioactive element is attached to the drug, when the drug binds to the bony tumor, the nuclear energy is localized where it is needed. http://www.vetmed.wsu.edu/news/Cassie.aspx
