BACKGROUND/AIM: Tumor lysis syndrome (TLS) is a life-threatening complication associated with cancer chemotherapy. We retrospectively evaluated the risk of developing TLS in patients with symptomatic multiple myeloma undergoing chemotherapy. PATIENTS AND METHODS: Sixty-four patients (median age=71 years, range=48-87 years, 35 males/29 females) who were treated at our Institution between April 2006 and December 2015 were evaluated. RESULTS: A total of 124 chemotherapy courses were administered, of which 63 courses were bortezomib-based regimens and 34 courses were immunomodulatory drug (IMiD)-based regimens...

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...

Introduction- Mantle cell lymphoma (MCL) is an incurable, often aggressive B-cell malignancy. Bortezomib (BTZ), the 20S proteasome inhibitor was originally developed and approved for treatment of relapsed refractory multiple myeloma, and subsequently approved for treatment of MCL. BTZ's single-agent activity induces clinical responses in approximately one-third of relapsed MCL patients. BTZ-containing combination therapies have further improved the quality and duration of clinical responses compared to standard chemotherapies in previously untreated MCL patients...

Novel treatment strategies have remarkably improved the multiple myeloma (MM) patients' survival, with associated increased costs. A joint panel meet of international experts from India and Ukraine was held in New Delhi on May 19, 2016 focusing on MM management, bortezomib role, unmet medical needs, and current challenges. The health-care system for oncology in India is majorly private vs. government-based in Ukraine. In India, electrophoresis, serum-free light chain assays, bone marrow tests, and X-rays are available modes of diagnosis...

The approval of several different classes of drugs in recent years has resulted in a dramatic expansion of treatment options for multiple myeloma patients, improving both survival and quality of life. Lenalidomide and bortezomib are now core components of treatment both at time of diagnosis and at relapse. Next-generation immunomodulatory drugs, like pomalidomide, and newer proteasome inhibitors like carfilzomib and ixazomib are available for use at relapse. Drugs with novel mechanisms of action such as the histone deacetylase inhibitor panobinostat and the monoclonal antibodies targeting SLAMF7 (elotuzumab) and CD38 (daratumumab) are significant steps forward...

Although there have been many definitions for high-risk (HR) myeloma, most recent consensus for classifying risk in patients with newly diagnosed multiple myeloma (NMM) comes from the International Myeloma Working Group. This recently published revised International Staging System includes del(17p) or t(4;14) by fluorescence in situ hybridization, β-2 microglobulin, albumin, and lactate dehydrogenase. These elements should be captured in all NMM patients. The optimal treatments for HR myeloma have not been fully worked out; therefore, these patients should be considered for clinical trials...

Acute myeloid leukemia (AML) is deadly hematologic malignancy. Despite a well-characterized genetic and molecular landscape, targeted therapies for AML have failed to significantly improve clinical outcomes. Over the past decade, proteasome inhibition has been demonstrated to be an effective therapeutic strategy in several hematologic malignancies. Proteasome inhibitors, such as bortezomib and carfilzomib, have become mainstays of treatment for multiple myeloma and mantle cell lymphoma. In light of this success, there has been a surge of literature exploring both the role of the proteasome and the effects of proteasome inhibition in AML...

Daratumumab (Darzalex[TM]) is a human monoclonal antibody (MAb) that targets CD38; a surface protein highly expressed across multiple myeloma (MM) cells. Preclinical studies have shown daratumumab induces MM cell death through several mechanisms, including complement-dependent cytotoxicity (CDC) antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), apoptosis upon secondary crosslinking and immunomodulatory effects via a decrease in immune suppressive cells. Daratumumab has a favorable toxicity profile and encouraging clinical activity as a single agent and in combination with lenalidomide in heavily pretreated, relapsed patients in whom other novel agents (such as bortezomib, thalidomide and lenalidomide) and stem cell transplant have already failed...

Chromosomal region 1p22 is deleted in ⩾20% of multiple myeloma (MM) patients, suggesting the presence of an unidentified tumor suppressor. Using high-resolution genomic profiling, we delimit a 58 kb minimal deleted region (MDR) on 1p22.1 encompassing two genes: ectopic viral integration site 5 (EVI5) and ribosomal protein L5 (RPL5). Low mRNA expression of EVI5 and RPL5 was associated with worse survival in diagnostic cases. Patients with 1p22 deletion had lower mRNA expression of EVI5 and RPL5, however, 1p22 deletion status is a bad predictor of RPL5 expression in some cases, suggesting that other mechanisms downregulate RPL5 expression...

The difficulty in the prediction of the complicated solid-state structure of boronic acid derivatives, resulting from the complex pathway of reversible covalent interactions, represents a significant obstacle to the development of a new generation of advanced supramolecular systems such as covalent organic frameworks of efficient anticancer drugs. In this contribution, various 2D (11)B-(11)B solid-state NMR correlation techniques supported by DFT calculations were explored to formulate a reliable tool for monitoring the covalent assembly of boronic acid residues in the solid state...

Even though the prognosis of patients with multiple myeloma is continuing to improve, all patients eventually develop relapsed refractory disease. Several novel therapeutics have been developed in the last few years including the second-generation proteasome inhibitor carfilzomib which has been approved for patients with relapsed and refractory multiple myeloma in the United States since 2012. Recently data from several phase III studies have become available showing the promising efficacy of carfilzomib in combination with lenalidomide, which led to the renewed approval of carfilzomib in combination with lenalidomide and dexamethasone for relapsed myeloma in 2015...

The significance of interphase fluorescence in-situ hybridization (iFISH) by regimen type was assessed in 692 AL amyloidosis patients with iFISH at diagnosis. First line treatment was categorized as stem cell transplant and three non-transplant regimens. The most common abnormality was t(11;14) (49% of patients) followed by monosomy 13/del(13q) (36%) and trisomies (26%). A lower rate of very good partial response (VGPR) or better was observed in patients with t(11;14) treated with bortezomib-based (52 vs 77%; P=0...

Although proteasome inhibitors such as Bortezomib had significant therapeutic effects in multiple myeloma and mantel cell lymphoma, they exhibited minimal clinical activity as a mono-therapy for solid tumors, including colorectal cancer. We found in the present study that proteasome inhibition induced a remarkable nuclear exportation of ubiquitinated proteins. Inhibition of CRM1, the nuclear export carrier protein, hampered protein export and synergistically enhanced the cytotoxic action of Bortezomib on colon cancer cells containing wild type p53, which underwent G2/M cell cycle block and apoptosis...

Itraconazole is one of the systemic treatment options for extensive tinea versicolor. A male patient who developed thrombocytopenia during the treatment of tinea versicolor by itraconazole is reported in this manuscript. He was diagnosed to develop thrombocytopenia on the third day of treatment. In the literature, there are two reports of itraconazole induced thrombocytopenia both in malignancy patients. One report contained three patients who developed thrombocytopenia as a result of a drug interaction between bortezomib and itraconazole...

Multiple myeloma (MM) is characterized by abnormal proliferation of neoplastic plasma cells. Pleural effusion as an initial presentation of this disease is rare, as is true pleural myeloma. We herein present a case of solitary pleural myelomatous lesion in a 70-year-old male patient diagnosed by pleural biopsy via semi-rigid thoracoscopy followed by histopathological examination. Furthermore, a review of the related English literature identified 22 cases of pleural myeloma, only 3 of which were diagnosed by video-assisted thoracoscopy...

While bortezomib is known to cause adverse effects involving the autonomic nervous system, gastrointestinal side effects are typically mild. We describe herein a series of patients with myeloma and impaired renal function who developed severe paralytic ileus secondary to bortezomib use. Our patients had other risk factors for paralytic ileus including electrolyte abnormalities and opiate use. The striking commonality in our patients is the development of paralytic ileus with intravenous bortezomib in the setting of reduced renal function, followed by ileus resolution with bortezomib dose reduction...

BACKGROUND: The outcome for patients with Multiple Myeloma (MM) is highly variable, therefore, the existence of robust and easy to determine prognostic markers is extremely important for an efficient management of these patients. Presently, there is a debate about the role of the serum free light chains (sFLC) in the prognosis of MM patients both at diagnosis and after treatment. The aim of this study is to evaluate in a cohort of newly diagnosed MM patients from the Southern area of Spain, the prognostic value of sFLC both at baseline and after treatment...

OBJECTIVE: there is no strong evidence to guide therapeutic approach to multiple myeloma (MM) patients who experience first relapse. The treatment choice can be difficult since currently all patients are exposed to novel agents as thalidomide, bortezomib and lenalidomide. METHODS: in this retrospective analysis we evaluated the best therapeutic sequence, the role of re-treatment and the most beneficial cut-off of first remission in order to choose re-treatment, analyzing 476 patients relapsed after first-line therapy...

Histone deacetylase (HDAC) inhibitors, which are approved for the treatment of cutaneous T cell lymphoma and multiple myeloma, are undergoing evaluation in other lymphoid neoplasms. How they kill susceptible cells is incompletely understood. Here we show that trichostatin A, romidepsin, and panobinostat induce apoptosis across a panel of malignant B cell lines, including lines that are intrinsically resistant to bortezomib, etoposide, cytarabine, and BH3 mimetics. Further analysis traces the pro-apoptotic effects of HDAC inhibitors to increased acetylation of the chaperone heat shock protein 90 (HSP90), causing release and degradation of the HSP90 client proteins RASGRP1 and CRAF, which in turn leads to downregulation of mitogen activated protein kinase pathway signaling and upregulation of the pro-apoptotic BCL2 family member BIM in vitro and in vivo...
