| Abstract | |
The frequent occurrence and high morbidity and lethality of oral cancer in dogs attach great importance to the problem, which constitutes a relevant issue not only for monitoring, but also to allow characterize risk populations and optimize parameters for the prevention, protection and patient care. The aim of this study was to evaluate the epidemiological of a survey convenience sample of dogs diagnosed with oral cancer in two different dental centers and two different cancer services in the city of São Paulo between January 2010 and December 2013. Observational epidemiological ecological, retrospective and prospective and multicenter study with oral cancer dogs, assessing the variables gender, reproductive status, age, life stage, breed, weight, dog size, location and size of the oral tumor and more frequent histological types and clinical staging. Three hundred and third medical records were analyzed and the results point to a higher frequency of malignant neoplasms (67%), the most frequent malignant melanoma (MM), followed by benign neoplasms (20%), the most frequent ameloblastoma (AMB) other injuries were non-neoplastic. There was no breed or gender preference, but the unneutered dogs were more likely to involvement by malignancy. The average age of dogs with malignant neoplasm was 11.22 years and 9.53 years in benign, geriatric animals were the most affected. Mean weight for malignant cancer was 17,13kg, tending to small and medium size dog, and benign 22,4kg, tending to medium and large, and small dogs have higher odds of occurrence of malignant tumor. The most frequent site is the jaw (35.5%) and the average size of neoformation was 3,52cm malignant and benign 1,53cm. Of patients with malignant neoplasm, geriatric have higher odds of death and the clinical stage IV was the most frequent. The histological type that prevailed was the MM for malignant neoplasms in small and medium-sized animals, and the AMB for benign in medium and large, and the senile and geriatric patients are more affected by malignant tumor, as well as small and spayed females, geriatric patients at higher risk of death from malignant tumor and stage IV is the most common (AU) | |
