Abstract

OBJECTIVE

To determine the clinical and pathological findings of rabbits diagnosed with lymphoma.

ANIMALS

16 rabbits.

PROCEDURES

The medical and pathology records database of the Veterinary Medical Teaching Hospital at the University of California, Davis was searched for rabbits diagnosed with lymphoma from 1996 to 2019.

RESULTS

Mean age of the 16 rabbits was 8 years (range, 4.5 to 12 years). Immunophenotyping was performed in 14 cases. Diffuse, large, B-cell lymphoma was most common (n = 7) followed by epitheliotropic, T-cell lymphoma (2); type II enteropathy-associated, T-cell lymphoma (2); marginal-zone, B-cell lymphoma (1); peripheral, T-cell lymphoma not otherwise specified (cutaneous nonepitheliotropic lymphoma; 1); primary, mediastinal (thymic) large B-cell lymphoma (1), and unclassified (cytology only with no immunophenotyping; 2). Multiple chemotherapy protocols were used on the basis of each individual animal’s disease state. Initial clinical improvement was reported for most rabbits receiving chemotherapy (5/6), with diffuse B-cell lymphoma responding most favorably to treatment. The 11 rabbits included in the survival analysis had a median survival time of 60 days (range, 1 to 480 days), and those diagnosed with B- and T-cell lymphoma had a median survival time of 8 and 36 days (range, 1 to 150 and 1 to 90 days), respectively.

CLINICAL RELEVANCE

Rabbits develop a range of lymphoma subtypes and, similar to humans and dogs, diffuse large B-cell lymphoma appears to be the most common. Chemotherapy treatments followed multiple protocols, which were mostly well tolerated and had a highly variable response. Further research into chemotherapy protocols is needed to optimize treatment of lymphoma in rabbits.

Abstract

OBJECTIVE

To describe the procedure of prostatic artery embolization (PAE) in dogs with prostatic carcinoma and to evaluate the short-term outcome for treated dogs.

ANIMALS

20 client-owned dogs with prostatic carcinomas between May 2014 and July 2017.

PROCEDURES

In this prospective cohort study, dogs with carcinoma of the prostate underwent PAE with fluoroscopic guidance. Before and after PAE, dogs underwent CT and ultrasonographic examinations of the prostate, and each owner completed a questionnaire about the dog's clinical signs. Results for before versus after PAE were compared.

RESULTS

Prostatic artery embolization was successfully performed in all 20 dogs. Tenesmus, stranguria, and lethargy were significantly less common 30 days after PAE (n = 2, 1, and 0 dogs, respectively), compared with before PAE (9, 10, and 6 dogs, respectively). Median prostatic volume was significantly less 30 days after PAE (14.8 cm3; range, 0.4 to 48.1 cm3; interquartile [25th to 75th percentile] range, 6.7 to 19.5 cm3), compared with before PAE (21.7 cm3; range, 2.9 to 77.7 cm3; interquartile range, 11.0 to 35.1 cm3). All dogs had a reduction in prostatic volume after PAE, with a median prostatic volume loss of 39.4% (95% CI, 20.3% to 59.3%).

CONCLUSIONS AND CLINICAL RELEVANCE

Prostatic artery embolization was associated with decreased prostate volume and improved clinical signs in this cohort. The short-term response to PAE appears promising, and evaluation of the long-term impact on survival time is needed.
