Promising new drugs are being evaluated for treatment of multiple myeloma (MM), but their impact should be measured against the expected outcome in patients failing current therapies. However, the natural history of relapsed disease in the current era remains unclear. We studied 286 patients with relapsed MM, who were refractory to bortezomib and were(More)
This multicenter phase 2 trial investigated safety and efficacy of a new immunochemotherapeutic regimen combining rituximab (R) and fludarabine (F) in patients with fludarabine- and anthracycline-naive chronic lymphocytic leukemia (CLL). The rationale for using R + F includes single-agent efficacy of both drugs, in vitro synergism of R and F, and no(More)
Daratumumab is an anti-CD38 monoclonal antibody with lytic activity against multiple myeloma (MM) cells, including ADCC (antibody-dependent cellular cytotoxicity) and CDC (complement-dependent cytotoxicity). Owing to a marked heterogeneity of response to daratumumab therapy in MM, we investigated determinants of the sensitivity of MM cells toward(More)
Systemic infection by various pathogens interacts with the endothelium and may result in altered coagulation, vasculitis and atherosclerosis. Endothelium plays a role in the initiation and regulation of both coagulation and fibrinolysis. Exposure of endothelial cells may lead to rapid activation of coagulation via tissue factor (TF) expression and the loss(More)
Dear Editor, All-trans retinoic acid (ATRA) has become the mainstay in the treatment of acute promyelocytic leukemia (APL) because addition of ATRA to anthracyclines has been shown to improve disease-free survival and overall survival compared to chemotherapy alone [1]. ATRA induces the differentiation of leukemic promyelocytes into mature cells via its(More)
The combination of melphalan, prednisone, and thalidomide (MPT) is considered standard therapy for newly diagnosed patients with multiple myeloma who are ineligible for stem cell transplantation. Long-term treatment with thalidomide is hampered by neurotoxicity. Melphalan, prednisone, and lenalidomide, followed by lenalidomide maintenance therapy, showed(More)
Flow cytometric analysis is a recommended tool in the diagnosis of myelodysplastic syndromes. Current flow cytometric approaches evaluate the (im)mature myelo-/monocytic lineage with a median sensitivity and specificity of ~71% and ~93%, respectively. We hypothesized that the addition of erythroid lineage analysis could increase the sensitivity of flow(More)
The 8p11 myeloproliferative neoplasm (8p11 MPN) is a rare disorder that is molecularly characterized by fusions of diverse partners to the tyrosine kinase receptor gene FGFR1. It can rapidly transform to acute myeloid leukemia. Here we report on a case with a t(8;13)(p11.2;q12.1) ZMYM2-FGFR1 fusion, with massive tumor lysis upon tyrosine kinase inhibition(More)
The prognosis of multiple myeloma (MM) patients who become refractory to lenalidomide and bortezomib is very poor, indicating the need for new therapeutic strategies for these patients. Next to the development of new drugs, the strategy of combining agents with synergistic activity may also result in clinical benefit for patients with advanced myeloma. We(More)
