Resumo
Mammary neoplasms are the most frequent tumors in female dogs. Of these neoplasms, benign mixed tumors (BMTs) and carcinomas in mixed tumors (CMTs) represent a large proportion of small animal oncology diagnoses. Together with carcinosarcomas (CSs), these three neoplastic entities are characterized by the proliferation of benign or malignant epithelial, myoepithelial, and mesenchymal cells, depending on their histological types. This histological heterogeneity, in addition to their molecular heterogeneity, confers these tumors with distinct biological behavior, which results in the need for different clinical and therapeutic approaches. The present consensual document elucidates the oncological issues related to the diagnosis, prognosis, and treatment of BMTs, CMTs, and CSs of the canine mammary gland.

The purpose of this paper is to establish criteria that could guide the diagnosis, prognosis and treatment of caninemammary neoplasias. It was elaborated during the Mammary Pathology Meeting: Diagnosis, Prognosis and Treatment ofthe Canine Mammary Neoplasia, held on November 6th and 7th, 2010 in Belo Horizonte MG, Brazil. Academics fromseveral regions of Brazil were present and contributed to this work. After three years, a new discussion was foundnecessary in order to address important questions: 1 - Have Brazilian DVMs applied the consensus? 2 - What were the maindifficulties in applying the consensus? 3 - What were the obtained results? 4 - What were the main differences among thevarious oncology services/groups? 5 - How could the criteria be improved and uniformed? A spreadsheet that allowed datacollection and an abstract was submitted by each oncology service/group from various parts of the country. Based on theabstracts we identified the main differences in diagnosis and therapeutic conducts among the groups. These differences haveguided the discussions of the II Mammary Pathology Meeting and the publication of a second consensus that has beenrevised and updated. The II Mammary Pathology Meeting: Diagnosis, Prognosis and Treatment of the Canine mamaryNeoplasia, was held on December 9th, 10thand 11th, 2013 in Belo Horizonte MG, sponsored by the Laboratory ofComparative Pathology of the Federal University of Minas Gerais (UFMG), with the support of the Brazilian Associationof Veterinary Pathology (ABPV) and Brazilian Association of Veterinary Oncology (ABROVET). Academics from severalregions of Brazil were present and contributed to this work.
