Exames laboratoriais complementares indicados no apoio ao diagnóstico do linfoma difuso de grandes células B (LDGCB)

Abstract: O linfoma difuso de grandes células B (LDGCB) é um linfoma agressivo, heterogêneo, mas potencialmente curável com quimioterapia multiagente; compreende cerca de 30 a 40% dos linfomas não Hodgkin; ocorre principalmente nos indivíduos com mais de 70 anos e raramente em crianças. O LDGCB pode surgir como um evento de novo ou representar uma progressão ou transformação de um linfoma menos agressivo. O International Prognostica Index (IPI) é utilizado como um fator preditivo das conseqüências clínicas para o pacien… Show more

“…An antigen-dependent phase of B-cell development occurs at this site. In the germinal center of the secondary follicle, these lymphocytes are transformed into centroblasts that have a high rate of proliferation, while frequent and continuous somatic mutations of genes of the immunoglobulin variable chain occur, promoting maturation and differentiation into centrocytes and subsequently into plasma cells or in memory B-cells (17) . In the germinal center, the BCL2 gene expression is usually down regulated and BCL6 is hyperexpressed (8,17) .…”
