Comparação de duas classificações histopatológicas com o padrão de imuno-marcação para KIT, a avaliação da proliferação celular e com a presença de mutações no c-KIT de mastocitomas cutâneos caninos

Abstract: RESUMO: A graduação histopatológica é o método de eleição para prever o comportamento biológico do mastocitoma e, atualmente, são utilizados os métodos de Patnaik e de Kiupel para dividi-los em graus de malignidade. O objetivo do presente trabalho foi comparar as duas classificações histológicas com as variáveis clínicas, os marcadores imuno-histoquímicos e com a presença de mutações para verificar as características que estão mais relacionadas entre si e com os piores prognósticos. Foram avaliados 61 animais,… Show more

“…No remarkable correlation was observed between the number of eosinophils and histological grading, and this does not corroborate the findings of Gross et al (2005). Moreover, Oliveira (2008) and Carvalho et al (2017) reported no correlation between histological grading and eosinophil concentration, corroborating the results of this study. Therefore, the eosinophil count cannot be used to determine the degree of malignancy in MCT.…”

“…Most samples (50%) analyzed were classified as Patnaik et al (1984) grade I, 47.9% as grade II, and 2.1% (n = 1) as grade III. Other studies showed a predominance of grade II tumors (Kiupel et al, 2004;Sabattini et al, 2015;Carvalho et al, 2017). However, the grading suggested by Patnaik et al (1984) may be influenced by subjectivity of the observers.…”
