Epstein-Barr virus (EBV) infection is closely related to carcinogenesis of various cancers, and is also associated with the development of drug resistance in cancer stem cells. However, in EBV-positive cancer cells, the mechanistic details of the downstream signaling and the connection of PI3K with the NF-κB pathway for development of drug resistance remain controversial. Diffuse large B-cell lymphoma (DLBCL) and multiple myeloma (MM) cells infected by EBV display drug resistance-related proteins (MDR1, MRP1 and MRP2) and stem cell markers (OCT4 and SOX2)...

Plasmablastic lymphoma, a rare highly aggressive non-Hodgkin's lymphoma subtype, often associated with HIV infection, is a close differential diagnosis of plasmablastic myeloma. The 2 conditions may be morphologically and immunophenotypically identical. However, differentiating between the 2 conditions is critical for adequate patient management. Herein, we describe an unusual case of plasmablastic myeloma with biclonal gammopathy which was initially diagnosed as plasmablastic lymphoma based on lymph node biopsy and immunohistochemistry (IHC) results...

REVIEW
Pier Luigi Zinzani, Alessandro Broccoli
Efficacy, safety and mechanisms of action of novel agents in marginal zone lymphoma patients, both with a nodal and extranodal presentation, are reviewed. Data on lenalidomide, bortezomib and (90)yttrium-ibrutumomab tiuxetan are obtained from trials specifically designed for patients affected by marginal zone lymphoma and with various disease presentations. The role of targeted agents, such as obinutuzumab, ibrutinib and idelalisib, and of some very new drugs (venetoclax, copanlisib, ublituximab and TGR-1202) is also discussed, taking into account the most relevant experiences in patients with indolent non-Hodgkin's lymphomas...

17 Background: WM is a rare, indolent B-cell lymphoma with 1000 to 1500 new cases diagnosed annually in the US. The disease is incurable with current therapy. Prior to January 2015 when ibrutinib was approved by the US FDA for WM, there were no therapies approved in this indication. This study describes initial systemic anti-cancer therapy (SACT) and HRU among WM patients (pts). METHODS: A retrospective study using a large, national US claims database from 1/2007-10/2013 was conducted...

Achieving complete remission (CR) in childhood relapsed/refractory acute lymphoblastic leukaemia (ALL) is a difficult task. Bortezomib, a proteasome inhibitor, has in vitro activity against ALL blasts. A phase I-II trial, reported by the Therapeutic Advances in Childhood Leukaemia and Lymphoma (TACL) consortium, demonstrated that bortezomib with chemotherapy has acceptable toxicity and remarkable activity in patients with relapsed ALL failing 2-3 previous regimens. We evaluated bortezomib in combination with chemotherapy in 30 and 7 children with B-cell precursor (BCP) and T-cell ALL, respectively...

Mycosis fungoides (MF) and its leukemic variant Sézary syndrome (SS) comprise the majority of CTCL, a heterogenous group of non-Hodgkins lymphomas involving the skin. The CTCL's resistance to chemotherapy and the lack of full understanding of their pathogenesis request further investigation. With the view of a more targeted therapy, we evaluated in vitro the effectiveness of bortezomib and methotrexate, as well as their combination in CTCL cell lines, regarding apoptosis induction. Our data are of clinical value and indicate that the bortezomib/methotrexate combinational therapy has an inferior impact on the apoptosis of CTCL compared to monotherapy, with bortezomib presenting as the most efficient treatment option for SS and methotrexate for MF...

Disease Overview: Waldenström macroglobulinemia (WM) is a lymphoplasmacytic lymphoma with immunoglobulin M (IgM) monoclonal protein. Clinical features include anemia, thrombocytopenia, hepatosplenomegaly, lymphadenopathy, and rarely hyperviscosity. DIAGNOSIS: Presence of IgM monoclonal protein associated with ≥10% clonal lymphoplasmacytic cells in bone marrow confirms the diagnosis. The L265P mutation in MYD88 is detectable in more than 90% of patients. Risk Stratification: Age, hemoglobin level, platelet count, β2 microglobulin, and monoclonal IgM concentrations are characteristics required for prognosis...

Quercetin, a bioflavonoid contained in several vegetables daily consumed, has been studied for long time for its antiinflammatory and anticancer properties. Quercetin interacts with multiple cancer-related pathways such as PI3K/AKT, Wnt/β-catenin and STAT3. These pathways are hyperactivated in primary effusion lymphoma (PEL), an aggressive B cell lymphoma whose pathogenesis is strictly linked to the oncogenic virus Kaposis' Sarcoma-associated Herpesvirus (KSHV). In this study, we found that quercetin inhibited PI3K/AKT/mTOR and STAT3 pathways in PEL cells, and as a consequence, it down-regulated the expression of the prosurvival cellular proteins such as c-FLIP, cyclin D1 and cMyc...

Waldenström macroglobulinaemia (WM) is an indolent B-cell malignancy characterised by the presence of immunoglobulin M (IgM) paraprotein and bone marrow infiltration by clonal small B lymphocytes, plasmacytoid lymphocytes and plasma cells. The symptoms of WM are protean, often follow an asymptomatic phase and may include complications related to the paraneoplastic effects of IgM paraprotein. The revised 2016 World Health Organization classification includes the MYD88 L265P mutation, which is seen in >90% of cases, within the diagnostic criteria for WM...

Post-transplantation lymphoproliferative disorder is an aggressive complication of transplantation, most frequently of diffuse large B-cell lymphoma morphology and associated with Epstein-Barr virus (EBV) infection/reactivation. In this study the microenvironment of EBV(+) (n=23) and EBV(-) (n=9) post-transplant non-germinal center B-cell diffuse large B-cell lymphoma was characterized. Of EBV(+) cases somatic hypermutation analysis, gene expression profiling, and extensive phenotyping were performed. Our results demonstrated variable cytotoxic T-cell infiltration and significantly increased CD163(+) M2 macrophage infiltration in EBV(+) compared with EBV(-) post-transplant diffuse large B-cell lymphoma...

The ubiqutin-proteasome system (UPS) plays a role in rituximab-chemotherapy resistance and bortezomib (BTZ) possesses caspase-dependent (i.e. Bak stabilization) and a less characterized caspase-independent mechanism-of-action(s). Here, we define BTZ-induced caspase-independent cell death pathways. A panel of rituximab-sensitive (RSCL), rituximab-resistant cell lines (RRCL) and primary tumor cells derived from lymphoma patients (N = 13) were exposed to BTZ. Changes in cell viability, cell-cycle, senescence, and mitotic index were quantified...

Bortezomib (BTZ) is the first proteasome inhibitor approved by the US-FDA is majorly used for the treatment of newly diagnosed and relapsed multiple myeloma including mantle cell lymphoma. BTZ is hydrophobic in nature and is a major cause for its minimal presence as marketed formulations. The present study reports the design, development and characterization of dendrimer based formulation for the improved solubility and effectivity of bortezomib. The study also equally focuses on the mechanistic elucidation of solubilization by two types of dendrimers i...

The management of relapsed/refractory mantle cell lymphoma remains challenging. Patients with relapsed mantle cell lymphoma have been treated with multi-agent salvage chemotherapies; however, outcomes are poor. Although there have been studies in the relapse/refractory setting, current data indicate that autologous hematopoietic stem cell transplantation may be an especially useful approach in the front line setting in patients in first complete or partial remission following induction chemotherapy. Allogeneic hematopoietic stem cell transplantation is the only curative option, although reduced intensity conditioning in chemo-sensitive relapse or refractory mantle cell lymphoma provides better survival rates...

Plasmablastic lymphoma (PBL) is a rare subtype of diffuse large B cell lymphoma (DLBCL), often associated with HIV infection. We present a case of a 53-year-old HIV-negative man with untreated hepatitis C viral infection who presented with abdominal pain and lymphadenopathy. Lymph node and bone marrow biopsies were consistent with plasmablastic lymphoma. He had partial response (PR) to 6 cycles of EPOCH but disease progressed seven weeks later. Repeat biopsy was consistent with plasmablastic lymphoma. Three cycles of bortezomib, ifosfamide, carboplatin, and etoposide (B-ICE) chemotherapy resulted in a partial response (PR)...

Treatment response of follicular lymphomas (FL) is highly variable. We, therefore, investigated the role of FL cancer-associated fibroblasts (CAFs) on tumor cell viability, in particular in response to treatment with cytotoxic drugs. Stromal cells outgrown from FL patients were characterized and pure CAF populations were co-cultivated with FL cells. To analyze fibroblast-mediated effects, cells in co-culture were treated with ABT-737 and Bortezomib. The adherent cell population was positive for all fibroblastic markers tested and showed increased mRNA-expression of the activation marker FAP...
