Soft Tissue Sarcomas in Dogs
Lymphoma (Lymphosarcoma) continued...
A company in Great Britain called Pet Screening offers a genetic screening
test for canine lymphoma, based on genetic markers in a blood sample. They
suggest periodic screenings to detect lymphomas early on.
Treatment: Lymphoma localized to a single lymph node may be cured by
surgical removal of the involved node. However, in most dogs the disease is
widespread and a cure is unlikely. Chemotherapy using several agents offers the
best chance of remission, which may last a year or longer. When a dog comes out
of remission, chemotherapy “rescue protocols” may be used to induce a second or
even a third remission.
Hemangiosarcoma is a tumor of the vascular tissues. This cancer may be
noticed as a lump on a rib or an abdominal swelling, but can progress unnoticed
while growing on the heart, liver, or spleen. The cancerous growths are quite
fragile and often break off, “seeding” cancer throughout the body.
Alternatively, the first sign may be sudden death as a large area of tumor
ruptures and the dog bleeds to death internally.
Treatment: Surgery and chemotherapy may help prolong survival times but
cures are virtually never seen, even with surgery done before there are
