Exosomes derived from solid tumor cells are involved in immune suppression, angiogenesis, and metastasis, but the role of leukemia-derived exosomes has been less investigated. The pathogenesis of chronic lymphocytic leukemia (CLL) is stringently associated with a tumor-supportive microenvironment and a dysfunctional immune system. Here, we explore the role of CLL-derived exosomes in the cellula...
Chronic lymphocytic leukemia (CLL) is one of the chronic lymphoproliferative disorders (lymphoid neoplasms). It is characterized by a progressive accumulation of functionally incompetent lymphocytes. Patients with leukemia often seek unconventional treatments not prescribed by hematologist in order to improve their cancer treatment outcome or to manage symptoms. In the present report, a 76-year...
Chronic lymphocytic leukemia (CLL) shows evidence of familial aggregation, but the genetic basis is poorly understood. The existence of a linkage between HLA and Hodgkin lymphoma, another B-cell disorder, coupled with the fact that CLL is frequently associated with autoimmune disease, led to the question of whether the major histocompatibility complex (MHC) region is involved in familial cases ...
Chronic lymphocytic leukemia (CLL), the most frequent type of leukemia in western countries, is characterized by the progressive accumulation in blood, bone marrow and lymphoid tissues of monoclonal B lymphocytes with a characteristic immunophenotype. Despite advances in therapy and improved outcome, in most instances CLL is an incurable disorder. Signaling via the B-cell receptor (BCR), the up...
Clonal evolution is a key feature of cancer progression and relapse. We studied intratumoral heterogeneity in 149 chronic lymphocytic leukemia (CLL) cases by integrating whole-exome sequence and copy number to measure the fraction of cancer cells harboring each somatic mutation. We identified driver mutations as predominantly clonal (e.g., MYD88, trisomy 12, and del(13q)) or subclonal (e.g., SF...
Abstract Chronic lymphocytic leukemia (CLL)‐related symptoms impair the well‐being of patients, making improvement health‐related quality life (QoL) a goal treatment. The CLL14 trial demonstrated higher efficacy fixed‐duration venetoclax‐obinutuzumab (Ven‐Obi) compared to chlorambucil‐obinutuzumab (Clb‐Obi) in patients with previously untreated CLL. To assess patients' QoL, following patient‐re...
Coincidence of primary myelofibrosis (PMF) and chronic lymphocytic leukaemia (CLL) in one patient is a rare phenomenon. To date, eight cases have been described in the literature. A 61-year-old woman presented with transfusiondependent anaemia in February 2008. Peripheral blood count showed a normochromic, normocytic anaemia with a haemoglobin level of 6.0 g/dl, and the white blood cell count a...
BACKGROUND B-cell lymphomas are a diverse group of hematological neoplasms with differential etiology and clinical trajectories. Increased insights in the etiology and the discovery of prediagnostic markers have the potential to improve the clinical course of these neoplasms. METHODS We investigated in a prospective study global gene expression in peripheral blood mononuclear cells of 263 inc...
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world. Survival of CLL cells depends on their close contact with stromal cells in lymphatic tissues, bone marrow and blood. This microenvironmental regulation of CLL cell survival involves the stromal secretion of chemo- and cytokines as well as the expression of adhesion molecules. Since CLL survival may also be driv...
Acute myeloid leukemia (AML) has a poor prognosis due to treatment-resistant relapses. A humanized anti-CD33 antibody (Mylotarg) showed a limited response rate in relapsed AML. To discover novel AML antibody targets, we selected a panel of single chain Fv fragments using phage display technology combined with flow cytometry on AML tumor samples. One selected single chain Fv fragment broadly rea...
