Prevalence of neoplasm in canines in the university of the Llanos, during 2004 to 2007

Objective. Describe and classify neoplastic diseases diagnosed at the Veterinary Pathology Laboratory at the University of the Llanos, between 2004 and 2007. Materials and methods. As a source of information was used database of medical records and autopsy examinations of the Veterinary Clinic of the University of the Llanos. The samples came from specimens obtained by biopsies and tumors found during necropsy. We analyzed 322 clinical cases, of which 113 were for cancer diseases (35%).Results. In general, the most affected species was the dog (93 of 113 cases), mixed races being the most affected (p <0.05) and the organic system more injured skin, with 68 cases (60.2%), followed by the gland breast with 13 cases (11.5%). The highest incidence of neoplasms were: squamous cell carcinoma (15 cases), trichoepithelioma (11 cases) and canine mastocytoma III (10 cases). There was a positive relationship between age and presentation of tumors (p <0.01), sex was not a determining factor for the presentation of the disease (p> 0.05). Conclusions. The skin tumors were the most impact, perhaps because of the ease of diagnosis during the clinical consultation, compared with other neoplasms that affect deeper organs and tissues.
