Tumor estromal gastrointestinal: análise de fatores relacionados ao prognóstico

Abstract: RESUMO: Objetivo: estudar os critérios morfológicos e imunoistoquímicos relacionados ao prognóstico dos tumores estromais gastrointestinais. Métodos: o estudo foi retrospectivo de 42 casos de tumor estromal gastrointestinal (GIST). Vinte e cinco casos foram obtidos no arquivo do Serviço de Anatomia Patológica do Hospital Universitário Gaffrée e Guinle e os outros dezessete, do Serviço de Anatomia Patológica do Hospital Universitário Clementino Fraga Filho. Resultados: de acordo com a análise univariada os tumo… Show more

“…Currently CT with contrast is the complementary examination of surplus value, since it defines if there was tumor spread, as well as location and size [10]. As well as UDE and echo endoscopy are relevant imaging methods for the diagnosis The diagnostic confirmation, however, is due to the histopathological and immunohistochemically tests, which was positive for the Kit protein [10] [12].…”

“…Because no epidemiological studies exist on the matter, and the actual frequency of each one of those conditions is unknown, the diagnosis of a GIST must always be investigated, since every GIST is potentially malignant. Although there are prognostic factors that stratify GISTs according to their biological behavior 17,18,19 , reports exist on the development of metastases even in low-risk lesions (lesions between 2 and 5 cm with fewer than 5 mitoses/ 50 high-power fields) 7,20 . That fact demonstrates that no fully reliable prognostic factors are available to date.…”
