Renal (Kidney) Lymphosarcoma in Cats

Feline Renal Lymphosarcoma

Lymphosarcoma is a general term for malignant cancers of lymphoid tissues, which may affect multiple organs, including the kidneys. Lymphosarcoma is a very common type of cancer in both dogs and cats, but the form affecting the kidney is much more common in cats than dogs. Renal lymphosarcoma is cancer of the kidneys in cats.

Lymphosarcoma is caused by cancerous lymphocytes, a type of white blood cell. Middle aged to older dogs and cats are affected.

Lymphosarcoma is ultimately a fatal disease, but it often goes into remission with appropriate therapy. Many animals with renal lymphosarcoma often develop renal failure.

What to Watch For

Animals with multi-organ involvement may show other signs of illness such as behavior changes, lack of coordination, especially of the hind legs in cats, extreme hind limb weakness, and yellow discoloration of the skin (jaundice).

Give all medications as prescribed by your veterinarian. Some chemotherapy drugs are given orally, at home. Monitoring for response to therapy as well as side effects from the chemotherapy is important. Vomiting, diarrhea, inappetence, and lethargy are signs to watch for at home.

There are no measures to be taken to prevent development of renal lymphosarcoma.
