CALIRI, M.N.; FERRE, D.; PALMA LEOTTA, M.E.  and  GORLA, N.B.. Registry of canine neoplasias diagnosed at the Veterinary Practice Unit, Maza University, Argentina, 2006-2020. Rev. vet. [online]. 2023, vol.34, n.2, pp.36-47. ISSN 1669-6840.  http://dx.doi.org/10.30972/vet.3427042.

This study aims to present the relative frequency of canine tumors diagnosed at a Veterinary Practice Unit, University service with regional scope, in the period 2006- 2020. A retrospective analysis was carried out based on the information extracted from the medical records. In total, 4500 clinical histories were consulted, among which 238 cases of canine tumors were diagnosed. Information about epidemiological aspects was recorded. Neoplasms were confirmed by histological or cytological analysis in 49% of the cases, which were mostly malignant (60%). In the canine population under study, the animals manifested tumors primarily between 9 and 10 years of age. The 49.5% of the animals with neoplasia were of purebreds, represented mostly by Argentinian Dogo with squamous cell carcinoma and hemangiosarcoma, and boxer with mast cell tumor and multicentric lymphoma, which suggests a predisposition of certain breeds to some type of neoplasms. The most common tumor was Transmissible Venereal Tumor TVT (16% of the total neoplasms), presented mainly in mixed breeds. Next in order of frequency, mast cell tumors and hemangiosarcoma (8.4% each), followed by squamous cell carcinoma (7.6%). The registration of animal tumors is important to delineate the behavior of cancer in the canine population and to provide data that can be compared with human ones, useful for identifying possible risk factors. This study constitutes a preliminary step to characterize and understand the occurrence of canine tumors in the region.
