Despite very similar gene expression profiles, the clinical course of B-cell chronic lymphocytic leukemia (B-CLL) is heterogeneous. Immunoglobulin VH (IgVH) mutational status and expression of B-cell receptor (BCR) signaling mediators have been associated with disease progression. However, the consequences of BCR engagement on cell survival and evolution of(More)
Hydroxyurea is the standard therapy of chronic myelomonocytic leukemia (CMML) presenting with advanced myeloproliferative and/or myelodysplastic features. Response to hypomethylating agents has been reported in heterogeneous series of CMML. We conducted a phase 2 trial of decitabine (DAC) in 39 patients with advanced CMML defined according to a previous(More)
No constant genetic alteration has yet been unravelled in T-cell acute lymphoblastic leukemia (T-ALL), and, to date, the most frequent alteration, the SIL-TAL1 deletion, is found in approximately 20% of cases. Recently, two genes have been identified, the multiple tumor-suppressor gene 1 (MTS1) and multiple tumor-suppressor gene 2 (MTS2), whose products(More)
Transformation of Philadelphia (Ph)–nega-tive myeloproliferative neoplasms (MPNs) to myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) is associated with poor response to chemotherapy and short survival. Fifty-four patients with Ph-negative MPN (including 21 essential thrombocythemia [ET], 21 polycythemia vera [PV], 7 primary myelofibrosis, and(More)
UNLABELLED Rapidly fatal cases of invasive fungal infections due to a fungus later identified as Saprochaete clavata were reported in France in May 2012. The objectives of this study were to determine the clonal relatedness of the isolates and to investigate possible sources of contamination. A nationwide alert was launched to collect cases. Molecular(More)
BACKGROUND Good syndrome (GS) is a rare condition in which thymoma is associated with hypogammaglobulinemia. It is characterized by increased susceptibility to bacterial, viral, and fungal infections, as well as autoimmunity. Most patients have no circulating B cells. METHODS The French DEFicit Immunitaire de l'adulte cohort provides detailed clinical and(More)
Quantification of minimal residual disease may guide therapeutic strategies in mantle cell lymphoma. While multiparameter flow cytometry is used for diagnosis, the gold standard method for minimal residual disease analysis is real-time quantitative polymerase chain reaction (RQ-PCR). In this European Mantle Cell Lymphoma network (EU-MCL) pilot study, we(More)
The efficacy of azacitidine in patients with anemia and with lower-risk myelodysplastic syndromes, if relapsing after or resistant to erythropoietic stimulating agents, and the benefit of combining these agents to azacitidine in this setting are not well known. We prospectively compared the outcomes of patients, all of them having the characteristics of(More)
