摘要:: Multiple myeloma (MM) is a malignancy of the plasma cells (PCs) characterized by a wide variety of genetic and chromosomal abnormalities. In recent years, major attention was drawn to the significance of chromosomal aberrations involving chromosome arm 13q and the IGH region on chromosome band 14q32 as a prognostic indicator in MM. In this study we applied a combined cell morphology and FISH method for the analysis of coexistence of t(11;14)(q13;q32) with deletions of the long arm of chromosome 13 (Delta13) in PCs from 51 MM patients using several probes for the 13q14, 11q13, and IGH regions. We found 15 different variants of the t(11;14) that are the consequence of different 11q13 breakpoints and various deletions of Variable (del IGH Var) or Constant (del IGH Const) IGH segments and also duplications and losses of the IGH gene on the normal nontranslocated chromosome 14 as well as IGH/Cyclin D1 (CCND1) fusion on der(14) and CCND1/IGH fusions on der(11). A strong association between Delta13 and specific variants of t(11;14) was found: variants with deletion of the IGH gene or its segments were found only in MM cases with deleted chromosome 13, while the common translocation t(11;14) was found only in the MM cases with normal chromosome arm 13q. In contrast, we did not find any association between Delta13 and deletions of the IGH gene or its segments in the MM patients with t(4;14)(p16;q32).
