Retrospective study of neoplasms in company animals attended at the veterinary clinics hospital of the federal university of Pelotas during 2013 to 2017

Abstract

Cancer is one of the leading causes of death in dogs, studies estimate that 45% of animals over 10 years die of this disease. There are genetic and environmental factors that may be involved in the occurrence of the disease. Data collection systems are rare in Veterinary Medicine, but of great value for the understanding of the predisposing factors and frequency of the different tumors. By developing the disease naturally and sharing the same environment and lifestyle of their tutors, animals can be good models of the natural occurrence of various neoplasms that also affect humans. The present work carried out a survey of the frequency of 764 animals complaining of tumors and that had a diagnosis obtained by cytological or histopathological examination in the period from 2013 to 2017 in the HCV-UFPel. Tumors were divided into 13 groups according to the anatomical sites, in a classification based on ICD-O-3. The present work aims to provide data for epidemiological future in veterinary and comparative oncology. The most frequent groups were skin and subcutaneous tumors (40.84%), followed by tumors of the mammary glands (27.88%), tumors of the sexual organs and the reproductive system (9.95%) and tumors of the blood and hemolytic system (6.54%).
