tumor metastásico, primario desconocido, cáncerResumo
El tumor metastásico no siempre tiene un origen evidente, hasta en un tercio de los casos nunca se encuentra el tumor primario. Este artículo es una guía de los avances más recientes para mejorar el enfoque diagnóstico y el manejo del paciente, con este fatal y frecuente tumor. El objetivo de este articulo, además de ser una guía, es ayudar a evitar errores comunes y graves. Uno de los errores más importantes es no tener en cuenta el papel fundamental de la confirmación histológica, pues esta puede evitar investigaciones innecesarias.
En el articulo también se detallan los componentes de la evaluación estándar, la clasificación según su pronóstico y las indicaciones de la evaluación secundaria, que incluye las indicaciones de la endoscopia alta y baja, los marcadores tumorales, la tomografía por emisión de positrones, el papel que ocupa el perfil genético, la epigenética y el ADN viral. Por otro lado, se indica el momento en que se debe detener la investigación. Recientemente, el tratamiento se ha modificado y con ello parece cambiar la historia de estos pacientes y de sus contrapartes con primario conocidoDownloads
