Resumo


The increase in life expectancy and changes in the lifestyle of companion animals have contributed to the increasing number of neoplasia cases in dogs, with malignant tumors being the most frequent and leading cause of death in these animals. Several factors are involved in tumor development, including genetic predisposition, age, and reproductive status. Given the scarcity of data on canine neoplasms in the state of Tocantins and the high number of observed cases, this study aimed to investigate the prevalence and epidemiological aspects of tumors in dogs treated at the University Veterinary Clinic (UVC) of the Universidade Federal do Norte do Tocantins (UFNT) between 2018 and 2024. Medical records from the UVC-UFNT were analyzed, and information on breed, sex, age, reproductive status, history of contraceptive use, tumor location, affected organ system, and histological type was collected. During the evaluated period, 88 dogs were diagnosed with neoplasms. Most animals were mixed breed (51.1%), followed by Rottweiler (9.1%), Pinscher (7.9%), Pit Bull (5.7%), and Poodle (5.7%). A predominance of females (80.6%) and nonneutered animals (76.13%) was observed. Epithelial neoplasms predominated in the mammary region and reproductive system, with a significant association between sex and tumors of epithelial and mesenchymal origin (p < 0.05). The lack of information regarding contraceptive use in a large proportion of medical records limits the analysis of this factor. These results reinforce the greater predisposition of nonneutered and elderly female dogs to the development of neoplasms, highlighting the importance of early spaying as a preventive measure.

Keywords: Epidemiology. Neoplasms. Veterinary oncology.
