RESUMEN
El linfoma difuso de células grandes B (LDCGB) abarca 25 a 40% del total de los linfomas no Hodgkin (LNH) y es el subtipo histológico más frecuente en el mundo. En Ecuador, el LDCGB corresponde al 49% del total de los casos de LNH. La Organización Mundial de la Salud (OMS) planteó, en 2008, una clasificación que incluye variantes morfológicas y subtipos moleculares e inmunofenotípicos. Los subtipos inmunofenotípicos se identifican según el algoritmo de Hans (CD10, Bcl-6 y MUM-1) y se clasifican, con fines pronósticos en: centro germinal (CG) y no-centro germinal (NCG). Los nuevos hallazgos de caracterización molecular del LDCGB (como traslocaciones cromosómicas recurrentes del myc, Bcl2 y Bcl-6) permiten desarrollar terapias blanco.(AU)
ABSTRACT
Diffuse large B-cell lymphoma (DLBCL) makes up from 25% to 40% of all non-Hodgkin lymphomas (NHL) and is the most common histologic subtype worldwide. In Ecuador, DLBCL amounts to 49% of all NHL cases. In 2008, the World Health Organization (WHO) put forth a classification that includes morphological variants and molecular and immunophenotypic subtypes. The immunophenotypic subtypes are identified by the Hans algorithm (CD10, Bcl-6, MUM-1) and are classified as germinal center (GC) and nongerminal center (NGC). The new molecular characterization findings of LDCGB as recurrent chromosomal translocations of myc, Bcl2 and Bcl-6, allow the development of target therapies.(AU)
