DLBC-NHL: Gen-expressie profiel Figure 1. Subgroups of Diffuse Large-B-Cell Lymphoma According to Gene-Expression Profiles. Panel A shows the hierarchical clustering of diffuse large-B-cell lymphomas from 240 patients with untreated disease and 34 patients who had previously been treated or who had a preexisting low-grade lymphoma, according to the level of expression of 100 genes. Red areas indicate increased expression, and green areas decreased expression. Each column represents a single diffuse large-B-cell lymphoma, and each row represents a single gene. Genes that are characteristically expressed in germinal-center B-cell-like diffuse large-B-cell lymphomas or activated B-cell-like diffuse large-B-cell lymphomas are indicated. The dendrogram at the top shows the degree to which each diffuse large-B-cell lymphoma is related to the others with respect to gene expression. Panel B shows the number of samples with amplification of the c-rel locus and bcl-2 translocations in subgroups of diffuse large-B-cell lymphoma. The ratio of genomic copy number for the c-rel and {beta}2-microglobulin loci was determined by a quantitative polymerase-chain-reaction assay, and ratios greater than 2 were considered to indicate c-rel amplification. The bcl-2 translocations were detected with the use of a polymerase-chain-reaction assay for the main break-point cluster region that is frequently involved in the t(14;18) translocation. Data are from patients who had untreated diffuse large-B-cell lymphomas without preexisting cancer. Panel C shows Kaplan-Meier estimates of overall survival after chemotherapy among the 240 previously untreated patients, according to the gene-expression subgroup. Rosenwald A et al.

Development of the Six-Gene Model. Panel A shows Kaplan-Meier estimates of overall survival in the 66 patients with diffuse large-B-cell lymphoma, analyzed by quantitative reverse-transcriptase polymerase chain reaction with TaqMan probe-based assays. The dotted lines represent 95 percent confidence intervals. Panel B shows Kaplan-Meier curves for overall survival in the three groups (at low, medium, and high risk of death) as defined by a prediction model based on the weighted expression of six genes (LMO2, BCL6, FN1, CCND2, SCYA3, and BCL2). According to log-likelihood estimates, P=0.001 for the model based on a continuous variable, and P=0.02 for the model based on the three discrete groups shown in the figure.
