Chemoimmunotherapy for canine lymphosarcoma.

Thirty-two dogs with naturally occurring multicentric lymphosarcoma were randomly assigned to one of two treatment groups. One half of the animals received combination chemotherapy plus vitamin injections (controls) while the other half received indentical chemotherapy plus injections of chemically-modified tumor cell extract in Freund's complete adjuvant (vaccinates). Clinical staging revealed no bias between groups but showed that prognosis could be closely correlated with the severity of disease at initial presentation. Twenty dogs (62%), including 11 vaccinates and 9 controls, responded favorably to chemotherapy and were evaluated for length of first remission and total survival time. Both parameters were significantly longer in vaccinated dogs than in controls. These data suggest that immunological stimulation may be a helpful adjunct to conventional therapy in selected types of cancer when immunological principles are observed.

Concurrent renal adenocarcinoma and polycythemia in a dog.

Concurrent renal adenocarcinoma and polycythemia were diagnosed in a 19-month-old, female Rhodesian ridgeback. An unusually early presentation for this neoplasm, it is the second reported case of renal adenocarcinoma in a dog less than two years of age. Concurrent renal adenocarcinoma and polycythemia have been reported previously in four older dogs. In the dog of this report, clinical signs included brick-red mucous membranes, lethargy, a periodic systolic heart murmur, and engorged retinal vessels. A large retroperitoneal mass and pulmonary metastatic nodules were present at the time of diagnosis. Red blood cell count, packed cell volume, and hemoglobin concentration were greatly increased (12,940,000 red blood cells/microliter; 73.2%; and 26.6 g/dl, respectively). Histopathological diagnosis was renal adenocarcinoma. Polycythemia was the result of excessive erythropoietin production by the neoplasm.
