AIMS To validate and improve the existing algorithm (proposed by Hans et al.) to classify diffuse large B-cell lymphoma (DLBCL). METHODS AND RESULTS Tissue microarrays constructed from 81 patients with DLBCL were studied by immunohistochemistry for expression of CD10, Bcl-6, MUM1, Bcl-2, cyclin-D2, FOXP1 and PKC-gamma proteins. Cases were classified as(More)
Several recurrent translocations that involve chromosome band 8p11 have been described in myeloid malignancies. These translocations target two distinct genes: (1) FGFR1, a receptor tyrosine kinase for fibroblast growth factors, and (2) MOZ, a putative histone acetyltransferase whose precise function remains to be defined. Disruption of FGFR1 is associated(More)
BACKGROUND In 2009 the declaration by the World Health Organization of a global pandemic of influenza-H1N1 virus led to a vaccination campaign to ensure protection for immunocompromised patients. The goal of this study was to determine the efficacy of the 2009 H1N1 vaccine in patients with hematologic malignancies. DESIGN AND METHODS We evaluated humoral(More)
The 8p11 myeloproliferative syndrome is a rare, aggressive condition associated with reciprocal translocations of chromosome band 8p11, most commonly the t(8;13)(p11;q12). To identify the genes involved in this translocation, we used fluorescence in situ hybridization (FISH) analysis to show that the chromosome 8 breakpoints fell within YAC 899e2 and that(More)
The RUNX1 (AML1, CBFA2) gene is a member of the runt transcription factor family, responsible for DNA binding and heterodimerization of other non-DNA binding transcription factors. RUNX1 plays an important part in regulating haematopoiesis and it is frequently disrupted by illegitimate somatic recombination in both acute myeloid and lymphoblastic leukaemia.(More)
High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a recognized treatment option for patients with relapsed Hodgkin's lymphoma. We have analysed 67 patients who underwent ASCT after LACE (lomustine (CCNU), cytarabine (Ara-C), cyclophosphamide, etoposide) conditioning for relapsed (n=61) or primary refractory (n=6) Hodgkin's(More)
Chromosomal breakpoints associated with malignancy are known to cluster at particular regions of the karyotype. Based on a review of the literature we have identified a novel leukaemia syndrome associated with translocations involving 8p11. This syndrome is distinct from the previously described translocation t(8;16)(p11;p13) associated with acute(More)
Natural killer (NK) cells exert antimyeloma cytotoxicity. The balance between inhibition and activation of NK-cells played by the inherited repertoire of killer immunoglobulin-like receptor (KIR) genes therefore may influence prognosis. One hundred eighty-two patients with multiple myeloma (MM) were analyzed for KIR repertoire. Multivariate analysis showed(More)
A 43-year-old male presented with a myeloproliferative disorder with prominent lymphadenopathy. Examination of the bone marrow showed almost complete replacement by a population of cells with an acquired chromosomal translocation t(8;13)(p11;q12). There are two other case reports describing a similar clinical syndrome with t(8;13)(p11;q12) as the sole(More)
Myeloproliferative disorders frequently show deletions or rearrangements of the long arm of chromosome 13. We report here the cloning of RNF6, a new gene that maps close to the chromosome 13 breakpoint in a case of myelofibrosis with a t(4;13)(q26;q12). RNF6 is predicted to encode a 685-amino-acid protein with a coiled-coil domain and a RING-H2 finger at(More)
