IRF4/DUSP22 Gene Rearrangement by FISH
IRF4/DUSP22 Gene Rearrangement by FISH The IRF4/DUSP22 locus is rearranged in a newly recognized subtype of non-Hodgkin lymphoma, large B-cell lymphoma with IRF4 rearrangement. These lymphomas are uncommon, but are clinically distinct from morphologically similar lymphomas, Tests to Consider including diffuse large B-cell lymphoma, high-grade follicular lymphoma, and pediatric- type follicular lymphoma. The IRF4/DUSP22 locus is also rearranged in a subset of ALK- IRF4/DUSP22 (6p25) Gene Rearrangement negative anaplastic large cell lymphomas (ALCL), where this rearrangement is associated by FISH 3001568 with a signicantly better prognosis. Method: Fluorescence in situ Hybridization (FISH) Test is useful in identifying ALK-negative anaplastic large cell lymphomas and large B- Disease Overview cell lymphoma with IRF4 rearrangement The rearrangement is associated with an improved prognosis Incidence See Related Tests Large B-cell lymphoma with IRF4 rearrangement accounts for <1% of all non-Hodgkin B-cell lymphomas overall More common in younger patients, with an incidence of 5-6% under age 18 IRF4/DUSP22 rearrangement is found in 30% of ALK-negative ALCLs Symptoms/Findings Large B-cell lymphoma with IRF4 rearrangement typically presents with limited stage disease in the head and neck, while the presentation of ALK-negative ALCLs is variable. Disease-Oriented Information Patients with large B-cell lymphoma with IRF4 rearrangement typically have a favorable outcome after treatment. Rearrangement of the IRF4/DUSP22 locus in ALK-negative ALCL is associated with a better prognosis than ALK-negative ALCL without this rearrangement. Test Interpretation Analytical Sensitivity The limit of detection (LOD) for the IRF4/DUSP22 probe was established by calculating the upper limit of the abnormal signal pattern in normal cells using the Microsoft Excel BETAINV function. -

No mutation was seen in normal donors, while it was present in 101/117 (86%) WM patients, 27/31 (87%) IgM monoclonal gammapathies of uncertain significance (MGUS), 3/14 (21%) splenic marginal zone lymphomas and 9/48 (19%) non-germinal center (GC) diffuse large B-cell lymphomas (DLBCLs). The mutation was absent in all 28 GC-DLBCLs, 13 DLBCLs not subclassified, 35 hairy cell leukemias, 39 chronic lymphocyticleukemias(16withM-component), 25 IgA or IgG-MGUS, 24 multiple myeloma (3 with an IgM isotype), 6 amyloidosis, 9 lymphoplasmacytic lymphomas and 1 IgM-related neuropathy. Among WM and IgM- MGUS, MYD88 L265P mutation was associated with some differences in clinical and biological characteristics, although usually minor; wild-type MYD88 cases had smaller M-component (1.77 vs 2.72 g/dl, P ¼ 0.022), more lymphocytosis (24 vs 5%, P ¼ 0.006), higher lactate dehydrogenase level (371 vs 265 UI/L, P ¼ 0.002), atypical immunophenotype (CD23 À CD27 þþFMC7 þþ), less Immunoglobulin Heavy Chain Variable gene (IGHV) somatic hypermutation (57 vs 97%, P ¼ 0.012) and less IGHV3–23 gene selection (9 vs 27%, P ¼ 0.014). -

Several clinical trials of ibrutinib treatment combined with dexamethasone (DXMS) for relapsed MM have demonstrated high response rates, however, the mechanism still remains unclear. In this study, we explored the therapeutic effect and mechanism of ibrutinib combined with DXMS on MM in vitro and vivo. The apoptosis of MM cell lines and mononuclear cells from MM patients’ bone marrow induced by ibrutinib combined with DXMS was detected by flow cytometry and the expression of apoptosis-related proteins were detected by Western blot. -

What Is Multiple Myeloma?
cancer.org | 1.800.227.2345 About Multiple Myeloma Overview If you have been diagnosed with multiple myeloma or are worried about it, you likely have a lot of questions. Learning some basics is a good place to start. ● What Is Multiple Myeloma? Research and Statistics See the latest estimates for new cases of multiple myeloma and deaths in the US and what research is currently being done. ● Key Statistics About Multiple Myeloma ● What’s New in Multiple Myeloma Research? What Is Multiple Myeloma? Cancer starts when cells begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas. To learn more about how cancers start and spread, see What Is Cancer?1 Multiple myeloma is a cancer of plasma cells. Normal plasma cells are found in the bone marrow and are an important part of the immune system. The immune system is made up of several types of cells that work together to fight infections and other 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 diseases. Lymphocytes (lymph cells) are one of the main types of white blood cells in the immune system and include T cells and B cells. Lymphocytes are in many areas of the body, such as lymph nodes, the bone marrow, the intestines, and the bloodstream. When B cells respond to an infection, they mature and change into plasma cells. Plasma cells make the antibodies (also called immunoglobulins) that help the body attack and kill germs. Plasma cells, are found mainly in the bone marrow. -

As plasma cells show dysplasia or lymphocytoid morphology, they masquerade as monocytes or high fluorescent lymphocytes (HFL) on automated cell analyzer. The early suspicion and detection are of clinical importance for diagnostic and prognostic reasons. Methods: Automated cell analyzer was used for routine CBC examination. Peripheral blood smear examination was performed for enumeration and characterization of cells in peripheral blood followed by bone marrow examination and ancillary techniques. Conclusion: Lymphocyte-Monocyte peak with increased high HFL count on CBC should prompt a smear -

Here we report a 71 years old male patient with an aggressive MCL and depict the clonal evolution from initial diagnosis of typical MCL to relapsed blastoid MCL. During the course of disease, the patient was diagnosed with Classic Hodgkin lymphoma (CHL), and received CHL therapeutic regimen. Molecular analysis by next generation sequencing of both MCL and CHL demonstrated clonally related CHL with characteristic immunophenotype and PDL1/2 gains. Moreover, our data illustrate the clonal heterogeneity and acquisition of additional genetic aberrations including a rare fusion of SEC22B-NOTCH2 in the process of clonal evolution.
