BACKGROUND: Although the outcomes of patients with mantle cell lymphoma (MCL) have improved, there is still no cure. Bortezomib has a 33% response rate in relapsed/refractory MCL and has shown additive and/or synergistic effects in preclinical trials with known effective agents. METHODS: This is a report of a prospective phase 2 trial of bortezomib added to rituximab plus hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (BzR-hyperCVAD)/rituximab, high-dose methotrexate, and high-dose cytarabine (BzR-MA) for 95 patients with newly diagnosed MCL...

T cell chronic active EBV is a rare disease in which EBV is present predominantly in T cells which infiltrate the tissues; patients have high levels of EBV in the blood. If untreated, patients often develop liver failure, hemophagocytic lymphohistiocytosis, coronary artery aneurysms, EBV infiltrating T cells impairing organ function, or T cell lymphomas refractory to treatment. At present, hematopoietic stem transplantation is the only curative therapy, and it is critical to make a proper diagnosis and initiate transplantation before the disease progresses to an irreversible stage...

BACKGROUND: The addition of high-dose cytarabine to the treatment of mantle cell lymphoma (MCL) has significantly prolonged survival of patients, but relapses are common and are normally associated with increased resistance. To elucidate the mechanisms responsible for cytarabine resistance, and to create a tool for drug discovery investigations, we established a unique and molecularly reproducible cytarabine resistant model from the Z138 MCL cell line. METHODS: Effects of different substances on cytarabine-sensitive and resistant cells were evaluated by assessment of cell proliferation using [methyl-14C]-thymidine incorporation and molecular changes were investigated by protein and gene expression analyses...

BACKGROUND: Mantle cell lymphoma (MCL) has the worst prognosis of B-cell subtypes owing to its aggressive clinical disease course and incurability with standard chemo-immunotherapy. Options for relapsed MCL are limited, although several single agents have been studied. Lenalidomide is available in Italy for patients with MCL based on a local disposition of the Italian Drug Agency. SUBJECTS, MATERIALS, AND METHODS: An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on effectiveness and safety of lenalidomide use in real practice...

Multiple myeloma (MM) results from malignancy in plasma cells and occurs at ages > 50 years. MM is the second most common hematologic malignancy after non-Hodgkin lymphoma, which constitutes 1% of all malignancies. Despite the great advances in the discovery of useful drugs for this disease such as dexamethasone and bortezomib, it is still an incurable malignancy owing to the development of drug resistance. The tumor cells develop resistance to apoptosis, resulting in greater cell survival, and, ultimately, develop drug resistance by changing the various signaling pathways involved in cell proliferation, survival, differentiation, and apoptosis...

Tripartite motif containing 28 (TRIM28) as a transcriptional co-repressor has been reported playing a role in regulating DNA damage response (DDR), cell differentiation, immune response, and tumorigenesis. The present study was performed to explore the biological function and clinical significance of TRIM28 in B-cell non-Hodgkin lymphoma (B-NHL). Results of the study displayed that high expression of TRIM28 was positively associated with the poorer survival of B-NHL patients as an independent prognostic factor...

The first therapeutic proteasome inhibitor bortezomib has clinical efficacy in mantle cell lymphoma (MCL) which resulted in its incorporation in treatment algorithms for this disease. Impairment of proteasomal function by bortezomib is mediated via inhibition of the 20S core particle. However, proteasome function can also be modified by targeting upstream components of the ubiquitin-proteasome system. Recently, b-AP15 has been identified as a small molecule achieving proteasome inhibition by targeting the deubiquitinase (DUB) activity of the 19S regulatory subunit and was found to inhibit cancer cell growth in preclinical analyses...

Mantle cell lymphoma (MCL) is a rare but often aggressive B-cell non-Hodgkin lymphoma (NHL). Initial therapy can achieve high response rates but invariably patients relapse and die from their disease. Incorporating a maintenance phase into the treatment strategy may prolong remission duration and ultimately prolong survival. Areas covered: The current literature incorporating a maintenance phase into treatment strategies for newly diagnosed and pre-treated MCL patients has been summarized. A literature search was performed using search terms 'mantle cell lymphoma', 'indolent NHL', 'maintenance', 'interferon', 'rituximab', 'lenalidomide', 'bortezomib' and 'ibrutinib'...

Waldenström macroglobulinaemia (WM) is a rare and incurable lymphoma. Comparative studies evaluating the efficacy of primary therapy in symptomatic WM patients have not been performed. In this study, we compared response and survival outcomes in WM patients who received primary therapy with cyclophosphamide-dexamethasone-rituximab (CDR), bortezomib-dexamethasone-rituximab (BDR) and bendamustine-rituximab (Benda-R), as well as maintenance rituximab following primary therapy. Analyses were adjusted for relevant clinical factors associated with response and survival...

Plasmablastic lymphoma (PBL) is a rare and aggressive form of B-cell non-Hodgkin lymphoma. This subtype of lymphoma has a post-germinal center cell-of-origin called the plasmablast, and the immunophenotype is more consistent with that of a plasma cell than a lymphocyte. Because of these unique features, PBL is notoriously difficult to treat. Case reports and small reviews have evaluated the addition of agents directed against plasma cell disorders in combination with traditional lymphoma-directed regimens. We describe the largest case series to date, with the longest follow-up, evaluating bortezomib in combination with etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (V-EPOCH) for the treatment of PBL...

Nuclear factor-κB (NF-κB) proteins are transcription factors that play key roles in regulating most immune responses and cell death. Constitutively active NF-κB has been shown to exhibit chemoresistance by inducing anti-apoptosis in tumor cells. Multiple myeloma is known as a constitutive NF-κB activating disease, and the proteasome inhibitor bortezomib is used to treat multiple myeloma and mantle cell lymphoma. We demonstrate here that DANFIN (N,N'-bis-(2,4-dimethyl-phenyl)-ethane-1,2-diamine) functions as an inhibitor of the p65 family proteins and induces chemosensitization to bortezomib in multiple myeloma...

Pure red cell aplasia is an orphan disease, and as such lacks rationally established standard therapies. Most cases are idiopathic; a subset is antibody-mediated. There is overlap between idiopathic cases and those with T-cell large granular lymphocytic leukemia, hypogammaglobulinemia, and low-grade lymphomas. In each of the aforementioned, the pathogenetic mechanisms may involve autoreactive cytotoxic responses. We selected 62 uniformly diagnosed pure red cell aplasia patients and analyzed their pathophysiologic features and responsiveness to rationally applied first-line and salvage therapies in order to propose diagnostic and therapeutic algorithms that may be helpful in guiding the management of prospective patients, 52% of whom were idiopathic, while the others involved large granular lymphocytic leukemia, thymoma, and B-cell dyscrasia...

This Phase II trial evaluated the efficacy of bendamustine, bortezomib and rituximab in patients with previously untreated low-grade lymphoma. Eligible patients had low grade lymphoma with no previous systemic disease treatment. Treatment for all patients was given in 28-day cycles for a maximum of 6 cycles. Patients received rituximab 375 mg/m2 intravenously (IV) on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6; bendamustine 90 mg/m2 IV on days 1 and 2; and bortezomib 1·6 mg/m2 IV on days 1, 8 and 15...

MicroRNA (miRNA) dysregulation is a hallmark of cutaneous T-cell lymphoma (CTCL), an often-fatal malignancy of skin-homing CD4+ T cells for which there are few effective therapies. The role of microRNAs (miRs) in controlling epigenetic modifier-dependent transcriptional regulation in CTCL is unknown. In this study, we characterize a novel miR dysregulation that contributes to overexpression of the epigenetic reader bromodomain-containing protein 4 (BRD4). We used patient CD4+ T cells to show diminished levels of miR-29b compared with healthy donor cells...

Disease relapse remains the first cause of mortality of hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HCT). The risk of recurrence is elevated in patients with high-risk cytogenetic or molecular abnormalities, as well as when allo-HCT is performed in patients with refractory disease or with persistent molecular or radiological (PET-CT scan) residual disease. Within the frame of the 7th annual workshops of the francophone society for bone marrow transplantation and cellular therapy, the working group reviewed the literature in order to elaborate unified guidelines for the prevention and treatment of relapse after allo-HCT...

Patients with mantle cell lymphoma (MCL) usually respond to initial combination chemotherapy, but the disease inevitably relapses and often follows an aggressive course. Here, clinical study results published since 2008 for patients with relapsed/refractory MCL were reviewed to compare available evidence for treatment guidance. Most trials identified were non-randomized, phase II studies performed at a limited number of sites, and many evaluated MCL as one of multiple non-Hodgkin lymphoma subtypes. Additional randomized, comparative trials are needed...

Aberrant energy metabolism represents a hallmark of cancer and contributes to numerous aggressive behaviors of cancer cells, including cell death and survival. Despite the poor prognosis of mantle cell lymphoma (MCL), due to the inevitable development of drug resistance, metabolic reprograming of MCL cells remains an unexplored area. Posttranslational modification of proteins via O- GlcNAcylation is an ideal sensor for nutritional changes mediated by O -GlcNAc transferase (OGT) and is removed by O -GlcNAcase (OGA)...
