ASPECTOS CLÍNICO-EPIDEMIOLÓGICOS DAS NEOPLASIAS MAMÁRIAS EM CADELAS E GATAS ATENDIDAS NO HOSPITAL VETERINÁRIO DA UFPB

Abstract

Breast tumors are the most common type of neoplasia in dogs and the third most common in cats. The use of injectable progestogens is one of the factors that contribute to the tumor development, being the surgery the therapeutic approach of reference. This study aimed to evaluate cases of mammary neoplasias that occurred at the UFPB veterinary hospital using clinical records, investigating the relationship between contraceptive use and the development of neoplasms, and the efficacy of the treatment used. A total of 234 records were analyzed, including the diagnosis of neoplasia, evaluating age, race, contraceptive use, castration, type of therapy and occurrence of relapses, described in spreadsheets in MICROSOFT EXCEL®. Animals with mammary neoplasia presented an average of seven to ten years. The highest incidence occurred in undefined females, followed by the poodle and pinscher races, and siamese and angora rats in cats. Regarding contraceptive use, 34% of the bitches and 71% of the cats had already used it. Of the bitches 62% were whole and the cats accounted for 80%. The most commonly used technique was unilateral mastectomy, with recurrence in most cases. Therefore, it was concluded that the highest incidence occurred in non-breed animals, aged between seven and ten years. The lack of information on the records made it difficult to study the aspects of breast tumors and the rate of relapse. Regarding treatment, unilateral mastectomy has been the most commonly used technique.
