Transcriptional profiling of 29 cases of diffuse large B cell lymphoma

ABSTRACT: 29 cases of RCHOP treated DLBCL were profiled for gene expression. Different integrated annalysis were performed, including mirNA differential expression between cases classified according to the COO signature (see later) and correlation tests between gene and miRNA expression. After transcriptional profiling the cases were classified according to the cell of origin based on the classifier proposed by Wright et al (Wright G, Tan B, Rosenwald A, Hurt EH, Wiestner A, Staudt LM. A gene expression-based method to diagnose clinically distinct subgroups of diffuse large B cell lymphoma. Proc Natl Acad Sci U S A 2003;100:9991-6.).

Diffuse large B-cell lymphoma (DLBCL) prognostication requires additional biologic markers. miRNAs may constitute markers for cancer diagnosis, outcome, or therapy response. In the present study, we analyzed the miRNA expression profile in a retrospective multicenter series of 258 DLBCL patients uniformly treated with chemoimmunotherapy. Findings were correlated with overall survival (OS) and progression-free survival (PFS). miRNA and gene-expression profiles were studied using microarrays in an  ...[more]
