Este estudio tiene como objetivo presentar la frecuencia relativa de tumores caninos diagnosticados en una Unidad de Prácticas Veterinarias, servicio universitario de ámbito regional, en el periodo 2006- 2020. El análisis retrospectivo se realizó a partir de la información extraída de las historias clínicas, se consultaron 4500 en total, que evidenciaron 238 casos de tumores caninos. Se registró la información disponible acerca de aspectos epidemiológicos. Las neoplasias se confirmaron mediante análisis histológico o citológico en el 49% de los casos, los que en su mayoría fueron malignos (60%). En la población canina objeto de estudio, los animales manifestaron tumores principalmente entre los 9 y 10 años de edad. El 49,5% de los animales con neoplasia eran de raza pura, representados en su mayoría por Dogo Argentino con carcinoma de células escamosas y hemangiosarcoma, y bóxer con mastocitoma y linfoma multicéntrico, lo que sugiere una predisposición de ciertas razas a algún tipo de neoplasias. El tumor más frecuente fue el Tumor Venéreo Transmisible TVT (16% del total), presentado principalmente en mestizos. Le siguen en orden de frecuencia el mastocitoma y el hemangiosarcoma (8,4% cada uno), seguidos del carcinoma de células escamosas (7,6%). El registro de tumores en animales es importante para delinear el comportamiento del cáncer en la población canina y proporcionar datos que puedan compararse con los humanos, lo cual es útil para identificar posibles factores de riesgo. Este estudio constituye un paso preliminar para caracterizar y comprender la ocurrencia de tumores caninos en la región. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
