Abstract

Osteosarcoma is the most common primary bone tumor in dogs. While its diagnosis is often not difficult, staging and treatment options vary depending on the goals of treatment. Known causes of this tumor will be reviewed. This lecture will also cover the various diagnostic tests that are done to stage the tumor including bone biopsy and aspirates, the use of radiographs, CT and MRI imaging, bone scintigraphy and lymph node aspirates. Surgical options to treat the primary tumor will be discussed. Adjuvant therapy including the use of bisphosphonates as well as chemotherapy options and outcomes will also be reviewed. As pain control is an important aspect of managing this cancer, especially for clients who do not choose amputation or limb-sparing surgery for treatment, palliative measures will also be covered.
