Gene expression profiling signatures allow the identification of unclassifiable leukemic B-cell lymphoid neoplasms

Gene expression analysis of different B-cell chronic lymphoproliferative disorders We performed gene expression profiling to develop a robust GEP-molecular classifier for leukemic B-CLPD A total number of 189 purified leukemic B-CLPD samples (including: CLL (n=54), FL (n=12), HCL (n=4), HCLv (n=4), LPL (n=6), cMCL (n=30), nnMCL (n=24), SDRPL (n=4), SMZL (n=23), and B-CLPD NOS (n=28))were processed with Affymetrix U133 Plus2.0 array.
