Low‐risk identification in multiple myeloma using a new 14‐gene model

Abstract: Identifying the best gene expression pattern associated with low-risk disease in patients with newly diagnosed multiple myeloma (MM) is important to direct clinical treatments. The MM Survival Index14 (MMSI14) was developed from GEP data sets of 22 normal plasma cells (NPC), 5 MM cell lines (MMCL), 44 monoclonal gammopathy of undetermined significance (MGUS), and 351 newly diagnosed MM patients. R/bioconductor and siggenes package were used to obtain heatmap, boxplot and histogram whose results were then analy… Show more

“…For example, the limited length of 6 microarray probes (25-100 bp) can result in nonspecific binding of transcripts (Zhang et al 2002), particularly in disease states. Instead, many groups have sought to develop multigene biomarkers (sometimes called ''signatures'') composed of tens to hundreds of genes that could be assayed using technologies with superior performance on FFPE material, reduced cost, and increased performance (Chen et al 2012;Kratz et al 2012;Lenehan et al 2012).…”

“…Siggenes was used to identify the differentially expressed genes as previously described ( Chen et al, 2012 ). Since multiple two-group comparisons may introduce some errors, we further compared the three groups simultaneously, and then found the gene expression differences that were common to all comparisons ( Fig.…”

“…The 70-gene prognostic signature, developed by the University of Arkansas for Medical Sciences (UAMS) and commercialized under the name 'MyPRS ® ' (Myeloma Prognostic Risk Score; Signal Genetics Inc., Carlsbad, CA, USA) is a standardized method of MM prognostication used to identify high-risk disease [24] and contribute to guide therapeutic interventions [25,26]. The IFM15 (Intergroupe Francophone du Myélome) and the MM Survival Index14 developed from gene expression profiling (GEP) data [27], respectively, identified 15 genes strongly associated with survival and 14 genes associated with low-risk disease. All these innovative tools are of help to redefine prognostic stratification and might be useful for prediction of molecular targeted agents activity.…”
