Avaliação das margens cirúrgicas como fator prognóstico em tumores mamários de cadelas e estudo do sentimento de luto dos tutores após a perda de animais de estimação

Abstract

One of the neoplasms that occur most frequently in dogs is mammary neoplasia, which may have an unfavorable prognosis and lead the animal to death. Two studies were carried out, the first study with the objective of evaluating the relationship between surgical margins and the clinical and histopathological findings of female dogs with mammary neoplasia, and the second study aimed to obtain information about the feelings and what is the impact on the lives of the tutors , when facing the period of illness and death of their pets. In order to carry out the study on surgical margins, data were obtained through a retrospective study of patients treated at HCV UFPel, from 2016 to 2020, collecting patient review data, as well as clinical and histopathological information. 181 medical records were obtained and of these, 170 were recorded. It was observed that patients affected with anaplastic carcinomas have a greater chance of the margins being compromised, while those affected by malignant adenomyoepithelioma tended to have surgical margins free of neoplasia. For the second study, information was obtained through an online questionnaire, about the feeling of the tutors during the period of illness and/or death of the pets. 418 questionnaires were answered by tutors, and more than 70% (295) of the participants reported that both the period of illness and death were difficult periods, for most respondents their pet was like a child 294 (70,33 %). We conclude that the histopathological findings are related to the surgical margins, while the evaluated clinical parameters, such as: location, size, presentation did not interfere. Patients with anaplastic carcinomas are more likely to have the margins compromised, while those with malignant adenomyoepithelioma tend to have tumor-free surgical margins. We also concluded that when the loss of pets occurs, guardians have feelings similar to those of the loss of a human being, and we emphasize that during the period of illness, guardians are affected by feelings similar to those of when humans face terminal illnesses, characterizing anticipatory grief.
