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 detectable metastases.
