Resumo
O primário com maior incidência em cães e um dos mais agressivos, além de ter uma evolução rápida. Os ossos mais acometidos são os ossos longos do esqueleto apendicular: rádio, ulna, úmero, fêmur, tíbia e fíbula. Foi realizada uma revisão de literatura a fim de reunir as informações mais corretas e recentes sobre o OSA, com descobertas e atualizações. De posse das informações obtidas, realizou-se um levantamento dos casos de osteossarcoma primário diagnosticados em cães nos anos de 2015 a 2020 pelo Serviço de Patologia Veterinária do Hospital Veterinário da FMVZ – UNESP, no Campus de Botucatu (Júlio de Mesquita Filho). Então, fez-se uma comparação entre os dados obtidos nos exames citopatológicos desses animais, uma comparação entre os dados obtidos nos exames histopatológicos desses animais e finalmente uma comparação entre os dados obtidos tanto nos exames citopatológicos quanto nos histopatológicos. A intenção nessas três etapas é de se identificar características em comum dos acometidos pelo OSA e, assim, se encontrar um perfil retrospectivo capaz de distinguir antecipadamente os cães que estariam ainda no início do osteossarcoma primário ou identificar quais cães que ainda não desenvolveram esse tipo de tumor, mas teriam predisponência a desenvolvê-lo. Foi diagnosticado um número considerável de cães SRD com OSA, isso levou a um tipo de enquadramento em portes de raças baseado no peso. E foram encontradas incongruências entre os resultados desta pesquisa e outras realizadas por profissionais.
The primary osteosarcoma is the primary bone tumor with the highest incidence in dogs and it is one of the most aggressive bone tumors, also it develops very fast. The most affected bones are the long bones of the appendicular skeleton: radius, ulna, humerus, femur, tibia, and fibula. A literature review has been made with the intention of gathering the most recent and trustworthy information about the OSA, with discoveries and upgrades. Thus, having the information a research is made about the cases about primary osteosarcoma diagnosed in dogs from 2015 to 2020 by the Veterinary Pathology Service at the Veterinary Hospital of the FMVZ – UNESP, in the Botucatu Campus (Júlio de Mesquita Filho). Subsequently there is a comparison the data obtained from the cytopathological exams about these animals, then a comparison about the data we obtained from the histopathological exams about these animals, and at last a comparison about the data we obtained from both cytopathological and histopathological exams. The purpose in these three stages is to identify typical characteristics to all the affected for OSA so it’s possible to find a retrospective profile capable of distinguishing quite early the dogs that were right in the beginning of the primary osteosarcoma, or even identify which dogs among the healthy ones that would have predisposition to develop it. A great number of mixed breed dogs was among the dogs diagnosed with OSA so a conversion is made to the breed size based upon the mixed breed dogs’ weight. Furthermore, we found inconsistencies between the results of this research and other researches made by professionals.
