Expresión Inmunohistoquímica de Vimentina, CD 34 y c-Kit (CD 117) en Tumores Estromales Gastrointestinales (GISTs)

Abstract: RESUMEN:Los tumores estromales gastrointestinales (GISTs) comprenden a tumores de origen mesenquimal que antes eran clasificados como "tumores del músculo liso", no obstante los avances en el campo de la microscopía electrónica e inmunohistoquímica han permitido su diferenciación. Derivan de las células intersticiales de Cajal, representan el 1-2% de todas las neoplasias del tubo digestivo y son más frecuentes en personas mayores de 40 años, con igual incidencia en ambos sexos. Se estudiaron 30 casos de GISTs … Show more

“…In GISTs, mutation of the c-kit gene leads to SCF-independent activity, triggering cell division and genomic instability that result in neoplasia. ICC-derived GISTs can be identified by their immunohistochemical positivity for vimentin, CD34, and c-Kit [ 18 , 19 ]. These markers have allowed us to understand the pathogenesis of GIST and have made it possible to develop an effective treatment targeting c-Kit.…”
