Alternative polyadenylation is a rapidly emerging form of gene regulation, which in its simplest form, enables the generation of mRNA transcripts that code for the same protein but have 3'UTRs of different lengths and regulatory content. For oncogenes, shorter 3'UTRs would be preferred as a mechanism to evade miRNA regulation. The shortening of the 3'UTR of cyclin D1 in mantle cell lymphoma offers provocative insights into this process. Patient samples have revealed that 3'UTR shortening may occur due to mutations, or translocations that result in the generation of a chimeric 3'UTR...

Mantle cell lymphoma (MCL) usually takes an aggressive clinical course and carries a poor prognosis. Recently, progress has been made in the treatment of MCL including the development of a number of novel agents which target intracellular pathways and the extracellular microenvironment. These agents have transformed the landscape of available therapeutic options. Areas covered: The current literature on the novel agents which currently hold a licence for the treatment of MCL in the context of front-line therapy and in the relapsed/refractory setting is summarized...

Patients with relapsed or refractory (R/R) non-Hodgkin's lymphoma (NHL) have a poor prognosis and limited treatment options. We evaluated selinexor, an orally bioavailable, first-in-class inhibitor of the nuclear export protein XPO1, in this phase 1 trial to assess safety and determine a recommended phase 2 dose (RP2D). Seventy-nine patients with various NHL histologies, including diffuse large B cell lymphoma (DLBCL), Richter's transformation, mantle cell lymphoma (MCL), follicular lymphoma (FL) and chronic lymphocytic leukemia (CLL) were enrolled...

REVIEW
Sílvia Beà, Virginia Amador
Mantle cell lymphoma (MCL) is an aggressive lymphoid neoplasm, incurable with current therapies. The t(11;14)(q13;q32) involving cyclin D1 is considered the first oncogenic hit found in virtually all MCLs. However, additional secondary genomic alterations are essential for complete transformation. MCLs are genetically very unstable with several genetic alterations associated with its high proliferative behavior involving several oncogenic pathways. Furthermore, SOX11 is overexpressed in the majority of conventional MCLs (cMCL), including cyclin D1-negative cases, but absent in non-nodal leukemic MCL with indolent clinical behavior (nnMCL)...

To obtain insight into the ontogeny of mantle cell lymphoma (MCL), we assessed 206 patients from a morphological, immunohistochemical, and immunogenetic perspective. Our series included nodal (n = 151), extranodal (n = 28), and primary splenic (n = 27) MCL cases. Skewing of the immunoglobulin heavy variable (IGHV) gene repertoire was noted, with only four IGHV genes accounting for 46% of cases and approximately 70% of cases (107/154) bearing an imprint of somatic hypermutation (SHM) ranging from minimal to pronounced...

Obesity is a well-known risk factor for the development of cancer, but its influence on the course of disease is still controversial. We investigated the influence of body mass index (BMI) on overall survival (OS) in 502 patients with indolent non-Hodgkin's lymphoma or mantle cell lymphoma in a subgroup analysis of the StiL (Study Group Indolent Lymphomas) NHL1 trial. We defined a cut-off of 22.55 kg/m(2) by ROC calculation and Youden Index analysis and stratified patients into "low BMI" and "high BMI". Five-year OS was significantly longer in the high BMI group (82...

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma. Patients with MCL generally present with extensive lymphadenopathy and extranodal involvement. To the best of our knowledge, no cases of primary bone MCL with multiple vertebral compression fractures have been reported in the literature thus far. The current study reports the case of a 75-year-old Chinese male patient presenting with lower back pain for 1 year. B symptoms were not observed in the patient's medical history. X-ray revealed osteoporosis, and mixed osteolytic and osteosclerotic lesions in the T10 and L1 vertebrae with decreased height...

We herein report two patients with mantle cell lymphoma (MCL), who had isolated mass and multiple lymphomatous polyposis (MLP) in the gastrointestinal tract. In case 1, esophagogastroduodenoscopy revealed a protruding mass in the duodenum and double-balloon endoscopy disclosed numerous polypoid lesions in the ileum. Case 2 had polyposis in the duodenum and a large mass-forming lesion in the ascending colon. Based on the histologic and immunohistochemical findings of the biopsy specimens, the diagnosis of MCL was made in both patients...

Induction regimens for mantle cell lymphoma (MCL) can be categorized into highly intensive ones containing cytarabine and less intense regimens such as R (rituximab) CHOP or R-bendamustine. Prior publications have shown R-hyperCVAD can be associated with stem cell mobilization failures. However, those studies did not include the use of plerixafor as rescue for stem cell mobilization failure. We examined our database of 181 consecutive MCL patients from 2005 to 2015 who received upfront therapy with either R-hyperCVAD or less intense chemotherapy (R-bendamustine and R-CHOP only) regimens to assess impact of frontline chemotherapy on collection of hematopoietic cell progenitors prior to autologous stem cell transplant (ASCT)...

Sex-determining region Y-box 11 (SOX11) is an important diagnostic marker in mantle cell lymphoma (MCL). However, the direct oncogenic mechanisms and downstream effector pathways implicated in SOX11-driven transformation remain poorly understood. In the present study, we analyzed SOX11 expression in B-NHL, and used lentivirus-mediated RNA interference targeting SOX11 to investigate the resulting changes in cellular processes and the underlying mechanisms in MCL cell lines. We found that patients with higher SOX11 expression have superior overall survival (OS) and progression-free survival (PFS) compared to those with lower SOX11 expression...

CD22-targeted recombinant immunotoxins (rIT) are active in hairy cell leukemia or acute lymphoblastic leukemia (ALL), but not in mantle cell lymphoma (MCL) patients. The goal was to enhance rIT efficacy in vivo and to define a strong combination treatment. Activity of Moxetumomab pasudotox (Moxe) and LR combined with paclitaxel was tested against MCL cell lines in vitro and as bolus doses or continuous infusion in xenograft models. In the KOPN-8 ALL xenograft, Moxe or paclitaxel alone was active, but all mice died from leukemia; when combined, 60% of the mice achieved a sustained complete remission...

INTRODUCTION: CD 200 is a type I immunoglobulin super family membrane glycoprotein, which is expressed in various mature B-cell neoplasm (MBN). This study aimed at analyzing the expression pattern of CD200 by flow cytometry immunophenotyping (FCI) and to evaluate its utility in narrowing down the differential diagnosis of MBN, particularly in low-grade lymphomas. METHODS: A total of 160 samples were evaluated by FCI over a period of 2 years (July 2014-June 2016), by a panel of antibodies including CD200...

Despite the long history of bendamustine as treatment for indolent non-Hodgkin lymphoma, long-term efficacy and toxicity data are minimal. We reviewed long-term data from three clinical trials to characterize the toxicity and efficacy of patients receiving bendamustine. Data were available for 149 subjects at 21 sites. The median age was 60 years at the start of bendamustine (range 39-84), and patients had received a median of 3 prior therapies. The histologies included grades 1-2 follicular lymphoma (FL; n = 73), grade 3 FL (n = 23), small lymphocytic lymphoma (n = 20), marginal zone lymphoma (n = 15), mantle cell lymphoma (n = 9), transformed lymphomas (n = 5), lymphoplasmacytic lymphoma (n = 2) and not reported (n = 2)...

CONTEXT: - In hematopathology practice, abnormal expression of CD103 on B cells is detected by flow cytometry in hairy cell leukemia (HCL) and, in combination with other phenotypic and morphologic findings, provides diagnostic specificity and sensitivity. Immunostaining on paraffin sections makes it possible to perform immunophenotyping in situ. However, normal bone marrow contains CD103-positive cells, which are not B cells, making it difficult to be certain about low-level involvement by HCL...

The novel Bruton's tyrosine kinase inhibitor ibrutinib has demonstrated high response rates in B-cell lymphomas; however, a growing number of ibrutinib-treated patients relapse with resistance and fulminant progression. Using chemical proteomics and an organotypic cell-based drug screening assay, we determine the functional role of the tumour microenvironment (TME) in ibrutinib activity and acquired ibrutinib resistance. We demonstrate that MCL cells develop ibrutinib resistance through evolutionary processes driven by dynamic feedback between MCL cells and TME, leading to kinome adaptive reprogramming, bypassing the effect of ibrutinib and reciprocal activation of PI3K-AKT-mTOR and integrin-β1 signalling...

Interactions between the polo-like kinase 1 (PLK1) inhibitor volasertib and the histone deacetylase inhibitor (HDACI) belinostat were examined in diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL) cells in vitro and in vivo. Exposure of DLBCL cells to very low concentrations of volasertib in combination with belinostat synergistically increased cell death (apoptosis). Similar interactions occurred in GC-, ABC-, double-hit DLBCL cells, MCL cells, bortezomib-resistant cells and primary lymphoma cells...

BACKGROUND: Relapsed or refractory mantle cell lymphoma (MCL) has a poor prognosis. The best outcome is achieved in patients who have a partial or complete response to salvage treatment and proceed to allogeneic stem cell transplant. PATIENTS AND METHODS: Twenty-one patients were given a combination regimen of bortezomib, cyclophosphamide, and rituximab at MD Anderson Cancer Center as part of a single-arm, prospective, open-label phase II clinical trial. The median age was 66 years, with a median number of prior treatments of three...
