CCL3 and diffuse large B-cell lymphoma: By using real‐time RT‐PCR to detect the mRNA expression level of each gene from independent samples of 66 patients and applying the univariate analysis, they selected out six genes including LMO2, BCL6, CCND2, FN1, SCYA3, and BCL2 based on the rank of the gene's prediction ability and constituted a prediction model based on their mRNA expression level, which was independent of IPI and sufficient to predict the survival of DLBCL patients 8.
