Os dados são relacionados aos casos diagnosticados no Serviço de Oncologia Veterinário (SOVET) e no Laboratório Regional de Diagnóstico (LRD), da Universidade Federal de Pelotas (UFPEL), nos anos de 2010 a 2015. Com base nesses achados foram elaborado três artigos científicos. No primeiro artigo foi realizado uma abordagem para um melhor entendimento clínico, patológico, sobre diagnóstico e tratamento de neoplasmas mamários em caninos, pois com o aumento da expectativa de vida dos animais de companhia e, consequentemente o aumento da casuística clínica veterinária de animais com neoplasmas mamários se fez necessário essa abordagem literária. No segundo artigo cientifico foi realizado um levantamento de amostras de neoplasmas mamários recebidas nos anos de 2010 a 2015 no SOVET e LRD. Assim foi caracterizado dados epidemiológicos e anatomopatológicos relacionados as cadelas e aos neoplasmas mamários e associado com o tempo de sobrevida de cadelas com carcinossarcomas e carcinomas mamários. Foi demonstrado que os carcinossarcomas são neoplasmas de maior malignidade por apresentarem piores graus histológicos e maior comprometimento de margens cirúrgicas, bem como determinaram um menor tempo de sobrevida dos animais, com este tipo histológico bem como quando associados com outros carcinomas, não tendo predileção por raça, acometendo animais idosos e que utilizavam terapia hormonal. No terceiro artigo científico foi realizado uma avaliação histopatológica dos linfonodos de cadelas que apresentaram metástases de neoplasmas mamários e correlacionados estes com seu tipo histológico. O grupo dos carcinossarcomas, tipos especiais e sarcomas apresentaram o maior índice de metástases em linfonodos, com a frequência maior em animais sem raça definida (SRD), com uma média de 10 anos de idade. / In this dissertation, neoplasms of the mammary gland of bitches are discussed. The data are related to the cases diagnosed at the Veterinary Oncology Service (SOVET) and at the Regional Diagnostic Laboratory (LRD), Federal University of Pelotas (UFPEL), from 2010 to 2015. Based on these findings A literature review and two scientific papers were prepared. In the review of the literature, an approach for a better clinical and pathological understanding of the diagnosis and treatment of canine mammary neoplasms was carried out, since the increase in the life expectancy of companion animals and, consequently, the increase in the veterinary clinical casuistry of animals with Neoplasms if this literary approach was necessary. In the first scientific article was carried out a survey of samples of breast neoplasms received in the years 2010 to 2015 in SOVET and LRD. Thus epidemiological and anatomopathological data related to bitches and mammary neoplasms were associated with the survival time of bitches with carcinosarcomas and mammary carcinomas. Carcinosarcomas have been shown to be neoplasms of higher malignancy because they present worse histological grades and greater compromise of surgical margins, as well as they have determined a shorter survival time of the animals with this histological type as well as when associated with other carcinomas, not having a predilection for race, Affecting elderly animals and using hormonal therapy. In the second scientific article, a histopathological evaluation of the lymph nodes of bitches who presented metastasis of mammary neoplasms and correlated with their histological type was performed. The group of carcinosarcomas, special types and sarcomas presented the highest index of lymph node metastases, with the highest frequency of non-defined animals (SRD), with an average of 10 years of age.
