Resumo
O estudo das neoplasias mamárias tem um elevado interesse clínico e
científico pois representam uma das neoplasias mais frequentes nas cadelas. Para além
disso, comummente representam uma das causas de morte dos animais domésticos,
devido à capacidade de metastização elevada que acompanha muitas das neoplasias
mamárias malignas.
Foi realizado um estudo retrospectivo observacional composto por 29 cadelas
com neoplasias mamárias, sendo 19 benignos (51%) e 18 malignos (49%), perfazendo
um total de 37 tipos histológicos que foram submetidas a mastectomia e posterior
análise histopatológica no Hospital Veterinário NobreVet nas Caldas da Rainha entre
janeiro de 2010 e abril de 2017, durante um período mínimo de 2 meses e no máximo
até aos 71 meses, avaliando aspectos clínicos e histopatológicos. A caracterização foi
feita com base na espécie, raça, idade, apresentação clínica, classificação histológica,
características histológicas metastização regional e à distância e na sobrevida após
mastectomia. Ao ser analisada a idade dos animais afectados por tumores mamários,
obteve-se uma média de idades de 11 anos. Aquando da análise do tipo histológico
tumoral verificou-se que os tipos malignos e benignos mais comuns foram o carcinoma
mamário do tipo simples e o adenoma mamário do tipo complexo respectivamente.
Atendendo à avaliação dos graus de malignidade histológica observou-se o mesmo
número de casos pertencentes ao grau ll e grau lll de malignidade.
The study of breast neoplasms has a high clinical and scientific interest because they represent one of the most frequent neoplasias in bitches. In addition, they commonly represent one of the causes of death in companion animals, due to the high metastatic capacity that accompanies many of the malignant mammary neoplasms. A retrospective observational study was carried out consisting of 29 bitches with mammary neoplasias, being 19 benign (51%) and 18 malignant (49%), making up a total of 37 histological types that were submitted to mastectomy and later histopathological analysis at NobreVet Veterinary Hospital in Caldas da Rainha between January 2010 and April 2017, for a minimum period of 2 months and up to 71 months, evaluating clinical and histopathological aspects. The characterization was made based on the species, race, age, clinical presentation, histological classification, histological characteristics regional and distance metastasis and survival after mastectomy. When the age of the animals affected by mammary tumors was analyzed, a mean age of 11 years was obtained. When analyzing the tumor histological type, it was verified that the most common malignant and benign types were the complex mammary carcinoma and complex mammary adenoma respectively. Considering the evaluation of the degrees of histological malignancy, the same number of cases belonging to grade II and degree III of malignancy were observed.
