    Symptomatic multiple myeloma (MM) evolves from an asymptomatic precursor state termed monoclonal gammopathy of undetermined significance (MGUS) and smoldering myeloma (SMM). Angiogenesis plays a key role in the pathogenesis of MM but there are very limited data for angiogenesis in SMM. We measured the circulating levels of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), vascular endothelial growth factor (VEGF), and angiogenin in 54 patients with SMM. The results were compared with those of 27 MGUS patients, 55 MM patients, and 22 healthy controls. The expression of VEGF-A gene was also evaluated in 10 patients with SMM, 10 with symptomatic MM, and 10 with MGUS. The ratio of circulating Ang-1/Ang-2 was reduced in MM patients with symptomatic disease due to a dramatic increase of Ang-2 (pmyeloma, the alterations of angiopoietins along with VEGF contribute to myeloma cell growth, supporting the target of these molecules for the development of novel anti-myeloma agents.

    Multiple myeloma is preceded by an asymptomatic phase, comprising monoclonal gammopathy of uncertain significance and smoldering myeloma. Compared to the former, smoldering myeloma has a higher and non-uniform rate of progression to clinical myeloma, reflecting a subset of patients with higher risk. We evaluated the gene expression profile of smoldering myeloma plasma cells among 105 patients enrolled in a prospective observational trial at our institution, with a view to identifying a high-risk signature. Baseline clinical, bone marrow, cytogenetic and radiologic data were evaluated for their potential to predict time to therapy for symptomatic myeloma. A gene signature derived from four genes, at an optimal binary cut-point of 9.28, identified 14 patients (13%) with a 2-year therapy risk of 85.7%. Conversely, a low four-gene score (smoldering myeloma with a 5.0% chance of progression at 2 years. The top 40 probe sets showed concordance with indices of chromosome instability. These data demonstrate high discriminatory power of a gene-based assay and suggest a role for dysregulation of mitotic checkpoints in the context of genomic instability as a hallmark of high-risk smoldering myeloma.

    The majority of multiple myeloma (MM) patients have high levels of monoclonal immunoglobulin in the serum and/or urine and suppressed levels of the uninvolved immunoglobulins. The prognostic significance of this phenomenon has not been assessed sufficiently. In this study, our aim is to evaluate the prognostic significance of uninvolved immunoglobulin suppression measured by nephelometry in patients with new symptomatic MM and the association with other features of the disease. Between August 2003 and February 2015, 137 patients who were referred for the treatment of newly diagnosed symptomatic myeloma to the Hematology Department polyclinics of the İstanbul University İstanbul Faculty of Medicine were prospectively included and had available pretreatment immunoglobulin levels measured by nephelometry. Suppression of at least one uninvolved immunoglobulin was observed in 87% of patients and this situation was slightly more common in patients with immunoglobulin A myeloma but had no statistical significance (p>0.05). Uninvolved immunoglobulin suppression was also more common among patients who had bone marrow plasma cell infiltration of ≥40% and presented with anemia and hypercalcemia (p65 years, lactate dehydrogenase of >300 IU/L, bone marrow plasma cells of ≥40%, and β2-microglobulin of >3.5 mg/dL (pmunoglobulins. We observed that patients who had preserved uninvolved immunoglobulin levels had better treatment responses and better pathologic signs, but statistical significance could not be shown. Conversely, patients with suppression of even one of the uninvolved immunoglobulins had a shorter survival, but similarly, statistical significance could not be shown.

    To evaluate the clinical outcomes of symptomatic bone lesions in patients with multiple myeloma (MM) who received local radiotherapy (LRT). Fifty-one patients with 87 symptomatic bone lesions treated via LRT were analyzed. LRT was delivered at a median total dose of 21 Gy (range, 12 to 40 Gy) in a median of 7 fractions (range, 4 to 20 fractions). The clinical outcomes of LRT and the factors affecting treatment response were assessed. After a median follow-up time of 66.7 weeks, symptom relief was achieved for 85 of 87 lesions (97.7%). The median time to symptom relief was 7 days from the start of LRT (range, 1 to 67 days). The duration of in-field failure-free survival ranged from 1.1 to 450.9 weeks (median, 66.7 weeks). The radiation dose or use of previous and concurrent chemotherapy was not significantly associated with in-field failure for LRT (p = 0.354, 0.758, and 0.758, respectively). Symptomatic bone lesions in patients with MM can be successfully treated with LRT. A higher radiation dose or the use of concurrent chemotherapy may not influence the in-field disease control. A relatively low radiation dose could achieve remission of symptoms in patients with MM.

    The diagnosis of smoldering multiple myeloma (SMM) includes patients with a heterogeneous risk of progression to active multiple myeloma (MM): some patients will never progress, whereas others will have a high risk of progression within the first 2 years. Therefore, it is important to improve risk assessment at diagnosis. We conducted a retrospective study in a large cohort of SMM patients, in order to investigate the role of Bence Jones (BJ) proteinuria at diagnosis in the progression to active MM. We found that SMM patients presenting with BJ proteinuria had a significantly shorter median time to progression (TTP) to MM compared with patients without BJ proteinuria (22 vs 88 months, respectively; hazard ratio=2.3, 95% confidence interval=1.4-3.9, P=0.002). We also identified risk subgroups based on the amount of BJ proteinuria: ⩾500 mg/24 h, <500 mg/24 h and without it, with a significantly different median TTP (13, 37 and 88 months, P<0.001). Thus, BJ proteinuria at diagnosis is an independent variable of progression to MM that identifies a subgroup of high-risk SMM patients (51% risk of progression at 2 years) and ⩾500 mg of BJ proteinuria may allow, if validated in another series, to reclassify these patients to MM requiring therapy before the end-organ damage development.

    Smoldering multiple myeloma (SMM) presents a high risk of progression to symptomatic MM (sy-MM). Herein, we analyzed some predictors of development of sy-MM. In 144 patients with SMM, we also compared the risk of progression predicted by bone marrow plasma cell (BMPC) involvement on the bone marrow biopsy (BMB) versus bone marrow aspirates (BMA). From January 1980 to July 2010, 397 patients with SMM observed in 12 centers of the Multiple Myeloma GIMEMA (Gruppo Italiano Malattie EMatologiche dell'Adulto) Latium Working Group have been analyzed. At progression to sy-MM, the severity of clinical presentation was graded according to the need of intensive supportive care. After a median follow-up of 135 months, the cumulative incidence of progression rates to sy-MM were 45%, 55%, and 75% at 10, 15, and 20 years, respectively. Hemoglobin ≤12.5 g/dL, monoclonal component ≥2.5 g/dL, and BMPC ≥60% were the only parameters negatively affecting the cumulative incidence of progression. In particular, 10 of 397 (2.5%) patients with BMPC ≥60% had a 5.6-fold increased risk of fast progression (within 2 years), which occurred with severe clinical manifestations in 62% of cases. BMB was more sensitive for the detection of BMPC involvement, even though BMA was a more reliable indicator of a rapid progression to sy-MM. The highest risk of rapid evolution to sy-MM and the severity of clinical manifestation at the progression suggest that SMM patients with a BMPC ≥60% should be treated soon after diagnosis. Moreover, BMPC is a more reliable index for progression to sy-MM if assessed by BMA. Copyright © 2012 American Cancer Society.

    Owing to the positive clinical benefits obtained with new agents, complete remission (CR) can be used as a surrogate for overall survival, and should be achieved. Although multiple myeloma is a heterogeneous disease in terms of myeloma cell- and patient-related risk factors, patients should receive the most effective combination therapy based on proteasome inhibitors and/or immunomodulatory drugs (IMiDs) as backbone medication irrespective of the risks encountered in the setting of induction therapy ("one-size-fits-all" therapy), followed by consolidation/maintenance therapy to achieve CR with the ultimate goal of extended survival. Myeloma-defining biomarkers have been established to identify high-risk smoldering myeloma requiring treatment. The development of salvage treatments yielding better outcomes for relapsed/refractory myeloma is urgently needed. Upcoming novel molecular targeting agents with different modes of action and immunotherapeutic agents will be integrated into myeloma treatment regimens with a great therapeutic impact, and further evolution of the treatment paradigm for multiple myeloma is eagerly anticipated.

    Full Text Available Smoldering multiple myeloma (SMM is an asymptomatic precursor stage of multiple myeloma (MM characterized by clonal bone marrow plasma cells (BMPC ≥ 10% and/or M protein level ≥ 30 g/L in the absence of end organ damage. It represents an intermediate stage between monoclonal gammopathy of undetermined significance (MGUS and symptomatic MM. The risk of progression to symptomatic MM is not uniform, and several parameters have been reported to predict the risk of progression. These include the level of M protein and the percentage of BMPC, the proportion of immunophenotypically aberrant plasma cells, and the presence of immunoparesis, free light-chain (FLC ratio, peripheral blood plasma cells (PBPC, pattern of serum M protein evolution, abnormal magnetic resonance imaging (MRI, cytogenetic abnormalities, IgA isotype, and Bence Jones proteinuria. So far treatment is still not recommended for SMM, because several trials suggested that patients with SMM do not benefit from early treatment. However, the Mateos et al. trial showed a survival benefit after early treatment with lenalidomide plus dexamethasone in patients with high-risk SMM. This trial has prompted a reevaluation of early treatment in an asymptomatic patient population.

    The presence of CD19 in myelomatous plasma cells (MM-PCs) correlates with adverse prognosis in multiple myeloma (MM). Although CD19 expression is upregulated by CD81, this marker has been poorly investigated and its prognostic value in MM remains unknown. We have analyzed CD81 expression by multiparameter flow cytometry in MM-PCs from 230 MM patients at diagnosis included in the Grupo Español de Mieloma (GEM)05>65 years trial as well as 56 high-risk smoldering MM (SMM). CD81 expression was detected in 45% (103/230) MM patients, and the detection of CD81(+) MM-PC was an independent prognostic factor for progression-free (hazard ratio=1.9; P=0.003) and overall survival (hazard ratio=2.0; P=0.02); this adverse impact was validated in an additional series of 325 transplant-candidate MM patients included in the GEM05 myeloma.

    Periostin is an extracellular matrix protein that is implicated in the biology of normal bone remodeling and in different cancer cell growth and metastasis. However, there is no information on the role of periostin in multiple myeloma (MM). Thus, we evaluated periostin in six myeloma cell lines in vitro; in the bone marrow plasma and serum of 105 newly diagnosed symptomatic MM (NDMM) patients and in the serum of 23 monoclonal gammopathy of undetermined significance (MGUS), 33 smoldering MM (SMM) patients, 30 patients at the plateau phase post-first-line therapy, 30 patients at first relapse and 30 healthy controls. We found high levels of periostin in the supernatants of myeloma cell lines compared with ovarian cancer cell lines that were not influenced by the incubation with the stromal cell line HS5. In NDMM patients the bone marrow plasma periostin was almost fourfold higher compared with the serum levels of periostin and correlated with the presence of fractures and of diffuse magnetic resonance imaging pattern of marrow infiltration. Serum periostin was elevated in NDMM patients compared with healthy controls, MGUS and SMM patients and correlated with advanced disease stage, high lactate dehydrogenase, increased activin-A, increased bone resorption and reduced bone formation. Patients at first relapse had also elevated periostin compared with healthy controls, MGUS and SMM patients, while even patients at the plateau phase had elevated serum periostin compared with healthy controls. These results support an important role of periostin in the biology of myeloma and reveal periostin as a possible target for the development of antimyeloma drugs.

  17. Impact of CRAB symptoms in survival of patients with symptomatic myeloma in novel agent era

    2017-02-01

    Full Text Available The acronym CRAB summarizes the most typical clinical manifestations of multiple myeloma, these being hypercalcemia, renal failure, anemia, and bone disease. CRAB can be used to distinguish between active, symptomatic multiple myeloma and monoclonal gammopathy of undermined significance or smoldering myeloma. The distinction is relevant not only for classification and diagnosis but also for therapy. CRAB factors influence the prognosis of multiple myeloma. However, it is unclear whether the presence of CRAB factors has an influence on the prognosis of myeloma treated with novel agents. In the current study, patients with hypercalcemia and bone disease showed a significantly worse prognosis, whereas anemia and renal failure showed no difference in survival. Novel agents used for treatment of patients with renal failure suggested a favorable outcome compared with conventional therapy. Bone disease was the most common factor and may have the strongest prognostic value in symptomatic myeloma patients using novel agents.

    Smoldering multiple myeloma (SMM) is an asymptomatic plasma cell neoplasia, characterized by monoclonal plasma cell proliferation in the absence of end-organ damage, but with a high risk of progression to multiple myeloma. It has therefore to be distinguished from monoclonal gammapathy of undetermined significance (MGUS), which has a much lower risk of progression, but also from multiple myeloma, which remains an incurable disease and requires a specific treatment. The critical question in the management of SMM is whether an early therapeutic strategy could help delaying the progression to multiple myeloma, in order to lower the risk of serious complications related to this progression, or even to cure the disease. This early treatment could not be proposed to all SMM patients, who are indeed asymptomatic, and in whom the risk of toxicity could make it difficult to justify the potential benefit obtained. The challenge is to target early at diagnosis SMM patients with a high risk of progression, using available routine tests sufficiently reliable to warrant the therapeutic sanction which relies on it. Today however, apart from randomized studies, recommendations are to maintain therapeutic abstention in SMM patients. Copyright © 2013 Société nationale française de médecine interne (SNFMI).

    Multiple myeloma is a malignancy of plasma cell proliferation leading to production of monoclonal immunoglobins. Among the classic features of multiple myeloma are bone lesions, which typically manifest in the axial skeleton, vertebrae, pelvis, skull, ribs, and proximal extremities. The several types of multiple myeloma include symptomatic multiple myeloma, monoclonal gammopathy of undetermined significance, smoldering/indolent myeloma, and solitary plasmacytoma of bone. Although rare, plasmacytomas of the foot and ankle have been described in published studies. We present, to the best of our knowledge, the first description of classic diffuse myelomatosis lesions associated with symptomatic myeloma in the foot of a patient with advanced disease who was treated in the podiatric surgery clinic for pathologic fracture.

    Full Text Available Among 792 patients with multiple myeloma treated from 1987 to 2010 and assessed after 18 months, there were 167 patients with complete remission. For those 60 patients treated between 1987–1998 and with long followup, the latest relapse occurred after 11.8 years, so that 13 patients have remained in sustained complete remission for longer than 12 years (range 12–22 years. These results suggest that 3% of all patients treated during that period may be cured of multiple myeloma. In addition to immunofixation, more sensitive techniques for the detection of residual disease should be applied more consistently in patients with apparent complete remission in order to identify those with potential cure.

    The precursor states (named as monoclonal gammopathy of undetermined significance [MGUS] and smoldering multiple myeloma [SMM]) consistently exist before symptomatic multiple myeloma is diagnosed. After approximately 30 years have passed since Kyle et al. advocated MGUS and SMM for the first time, the pathology and prognosis of these diseases have been clarified considerably. Recently, the safety and efficacy of the early treatment for the patients with high risk SMM are shown. In this article, the current understanding of the pathology of SMM as well as MGUS including the diagnosis, prognosis and treatment is reviewed.

SMM is distinguished from monoclonal gammopathy of undetermined significance by a much higher risk of progression to multiple myeloma (MM). There have been major advances in the diagnosis, prognosis, and management of SMM in the last few years. These include a revised disease definition, identification of several new prognostic factors, a classification based on underlying cytogenetic changes, and new treatment options. Importantly, a subset of patients previously considered SMM is now reclassified as MM on the basis of biomarkers identifying patients with an ≥80% risk of progression within 2 years. SMM has assumed greater significance on the basis of recent trials showing that early therapy can be potentially beneficial to patients. As a result, there is a need to accurately diagnose and risk-stratify patients with SMM, including routine incorporation of modern imaging and laboratory techniques. In this review, we outline current concepts in diagnosis and risk stratification of SMM, and provide specific recommendations on the management of SMM. © 2015 by The American Society of Hematology.

    Full Text Available Multiple myeloma has been regarded as an incurable disease with frequent relapses. The diagnostic criteria have been revised multiple times to include early stage of the disease where treatment can be effective and can prolong the survival. Newer diagnostic criteria for myeloma have incorporated ≥60% plasma cells in the bone marrow and serum free light chain ratio (involved to uninvolved free light chains of ≥100. The role of positron emission tomography-computed tomography scans has been recognized, and it has been increasingly utilized upfront in the management of multiple myeloma. Role of minimal residual disease monitoring has been studied in multiple trials and will in near future guide the treatment. Autologous stem cell transplant is still the preferred consolidation therapy after initial three or four drug induction. With the use of novel drugs combinations and with emerging treatment options the standard of care of myeloma patients will change.

    The immunoglobulin D multiple myeloma is a rare form of multiple myeloma and affects a young population. It is characterized by its clinical severity and poor prognosis. We report four cases of multiple myeloma immunoglobulin D diagnosed and supported in the university hospital Center of Sale and Rabat-Morocco. We propose to study the epidemiological, clinical and biological characteristics of this rare type of monoclonal gammopathy. Through the observations reported, the clinical aspect of myeloma is characterized by the high frequency of extra-bone manifestations including impaired kidney function. The immunoglobulin D multiple myeloma is mainly type λ, the IgD κ is rare, the predominance of λ light chains could be explained by rearrangements at the immunoglobulin genes. Bence-Jones proteinuria is almost constant in the multiple myeloma immunoglobulin D, it is mainly type λ, reflecting excess production of light chains by plasma cells. The marrow is invaded by plasma cells in very different proportions of up to 95%. It's a clinical entity, difficult to diagnose, particularly when low homogeneous band on electrophoresis goes unnoticed for an eye inexperienced or when immune serum anti-IgD was not used during the immunotyping.

    Full Text Available Multiple myeloma survival has significantly improved in latest years, due to a broad spectrum of novel agents available for treatment. The introduction of thalidomide, bortezomib and lenalidomide together with autologous stem cell transplantation has dramatically prolonged complete remissions rate, progression free survivals resulting ultimately in prolonged survivals in myeloma patients. Moreover, novel strategies of treatment such as consolidation and maintenance are being used to implement responses. A number of new drugs such as carfilzomib and pomalidomide are already in clinical practice, and new kids on the block are entering, making the future of myeloma patients brighter.

    Full Text Available The objectives of this paper are to discuss a rare cause of laryngeal multiple myeloma, to review unique pathologic findings associated with plasma cell neoplasms, to discuss epidemiology, differential diagnosis, and treatment options for plasma cell neoplasms of the larynx. Laryngeal multiple myeloma, also noted in the literature as “metastatic” multiple myeloma, presenting as a de novo laryngeal mass is extremely rare with few reported cases. Laryngeal involvement of extramedullary tumors is reported to be between 6% and 18% with the epiglottis, glottis, false vocal folds, aryepiglottic folds, and subglottis involved in decreasing the order of frequency. We present the case of a 58-year-old male with a history of IgA smoldering myeloma who presented to a tertiary care laryngological practice with a two-month history of dysphonia, which was found to be laryngeal involvement of multiple myeloma. We review the classification of and differentiation between different plasma cell neoplasms, disease workups, pathologic findings, and treatment options.

    -rays, CT scans and MRI scans. Major and minor criteria are required to confirm the diagnosis of multiple myeloma and help to determine the classification and staging of multiple myeloma, and whether it is smoldering myeloma (asymptomatic), symptomatic myeloma, or a monoclonal gammopathy of undetermined significance (MGUS). Multiple myeloma treatment options have increased significantly over the last 10 years. Standard of basic myeloma treatment consists of high dose chemotherapy in combination with autologous stem cell transplantation. Several factors may determine multiple myeloma treatment, such as age and general health, results of laboratory and cytogenetic (genomic) tests as well as symptoms and disease complications. After evaluation of these factors, an individual and often multimodal treatment plan is created and implemented in interdisciplinary cooperation. Conventional treatment options have to be evaluated for older patients (> 70 - 75 years), who are not eligible for high dose chemotherapy and autologous stem cell transplantation due to their age and/or severe comorbidities. It is essential to include supportive therapy in the integral treatment concept, in order to control pain or retain function or mobility. Supportive drugs such as bisphosphonates but also radiation therapy and orthopaedic surgery may be required in order to manage complications of the disease as well as side effects of treatment. Conclusion Current studies show promising results in the treatment of multiple myeloma, due to new agents such as immunomodulatory drugs, proteasome inhibitors and antibodies, which may improve prognosis and survival rate among myeloma patients in the future. However treatment algorithms have become more complex and expensive. Georg Thieme Verlag KG Stuttgart · New York.

    Smoldering (asymptomatic) multiple myeloma is an asymptomatic plasma-cell proliferative disorder associated with a high risk of progression to symptomatic multiple myeloma or amyloidosis. Prognostic factors for the progression and outcome of this disease are unclear. We searched a computerized database and reviewed the medical records of all patients at Mayo Clinic who fulfilled the criteria of the International Myeloma Working Group for the diagnosis of smoldering multiple myeloma between 1970 and 1995. Bone marrow aspirate and biopsy specimens were studied, and patients were followed throughout the course of disease. During the 26-year period, 276 patients fulfilled the criteria for smoldering multiple myeloma. During 2131 cumulative person-years of follow-up, symptomatic multiple myeloma or amyloidosis developed in 163 persons (59%). The overall risk of progression was 10% per year for the first 5 years, approximately 3% per year for the next 5 years, and 1% per year for the last 10 years; the cumulative probability of progression was 73% at 15 years. At diagnosis, significant risk factors for progression included the serum level and type of monoclonal protein, the presence of urinary light chain, the extent and pattern of bone marrow involvement, and the reduction in uninvolved immunoglobulins. The proportion of plasma cells in the bone marrow and the serum monoclonal protein level were combined to create a risk-stratification model with three distinct prognostic groups. The risk of progression from smoldering multiple myeloma to symptomatic disease is related to the proportion of bone marrow plasma cells and the serum monoclonal protein level at diagnosis.

    The treatment of multiple myeloma has evolved significantly over the past 2 decades due to the use of high-dose chemotherapy and autologous stem cell transplantation, and the subsequent introduction of the immunomodulatory agents (thalidomide and lenalidomide) and the proteasome inhibitor (bortezomib). The median overall survival of multiple myeloma patients has increased significantly with patients younger than age 50 years experiencing a 10-year survival rate of around 40%. However, despite the increased effectiveness of the first-line agents, the majority of patients will eventually relapse and become drug resistant. Promising novel therapies have recently emerged and are being used to treat relapsed and refractory patients. This review will cover the clinical data regarding these emergent therapies that include new generation of proteasome inhibitors (carfilzomib, ixazomib, oprozomib, and marizomib), immunomodulatory drugs (pomalidomide), monoclonal antibodies (elotuzumab and daratumumab), signal transduction modulator (perifosine), and histone deacetylase inhibitors (vorinostat and panobinostat).

    To evaluate whole-body MRI (WB-MRI) parameters significantly associated with treatment response in multiple myeloma (MM). Twenty-one MM patients underwent WB-MRI at diagnosis and after two cycles of chemotherapy. Scans acquired at 3.0 T included T2, diffusion-weighted-imaging (DWI) and mDixon pre- and post-contrast. Twenty focal lesions (FLs) matched on DWI and post-contrast mDixon were selected for each time point. Estimated tumour volume (eTV), apparent diffusion coefficient (ADC), enhancement ratio (ER) and signal fat fraction (sFF) were derived. Clinical treatment response to chemotherapy was assessed using conventional criteria. Significance of temporal parameter change was assessed by the paired t test and receiver operating characteristics/area under the curve (AUC) analysis was performed. Parameter repeatability was assessed by interclass correlation (ICC) and Bland-Altman analysis of 10 healthy volunteers scanned at two time points. Fifteen of 21 patients responded to treatment. Of 254 FLs analysed, sFF (p < 0.0001) and ADC (p = 0.001) significantly increased in responders but not non-responders. eTV significantly decreased in 19/21 cases. Focal lesion sFF was the best discriminator of treatment response (AUC 1.0). Bone sFF repeatability was excellent (ICC 0.98) and better than bone ADC (ICC 0.47). WB-MRI derived focal lesion sFF shows promise as an imaging biomarker of treatment response in newly diagnosed MM. (orig.)

    The management of smoldering multiple myeloma (SMM) has been a challenge to clinicians, ever since the condition was first characterized in 1980. While the risk of progression to symptomatic myeloma is greater for SMM (10% per year) compared to MGUS (1% per year), several SMM patients remain asymptomatic for years without evidence of disease progression. Early clinical trials focusing on early treatment of SMM have been equivocal with no clear benefit. However, the last decade has seen a greater understanding of the pathogenesis of plasma cell disorders, including SMM, and development of better therapeutics. A recent randomized trial has provided evidence of clinical benefit with early treatment of high-risk SMM. In this review, we summarize issues related to the early treatment of SMM including risk stratification and possible outcomes with therapy initiation. In the context of reviewing recent clinical trial data supporting early treatment, we define challenges faced by clinicians and provide future directions to the road to treating SMM.

    Monoclonal gammopathy of unknown significance (MGUS) as one of the most common premalignant disorders and smoldering multiple myeloma (sMM) are both caused by a proliferation of monoclonal plasma cells leading to a detectable serum monoclonal protein and/or excess of plasma cells in the bone marrow. Prerequisite for the diagnosis is that plasma cell disease does not cause clinical symptoms. Cytogenetic aberrations are detectable in the majority of patient in the clonally expanded plasma cells. MGUS consistently proceeds symptomatic MM. The lifetime risk of progression into symptomatic multiple myeloma lies between 15% and 59% for patients with MGUS or sMM. Prognostic parameters for development of symptomatic multiple myeloma from MGUS or sMM are concentration of monoclonal protein, bone marrow plasmocytosis, a non- IgG subtype and an abnormal free-light chain ratio. Detection of more than 1 focal lesion in whole body MRI, 95% or more of bone marrow plasma cells displaying an aberrant phenotype in flow cytometry and an evolving clinical course in two consecutive follow-up visits are additional prognostic parameters for sMM. Currently there is no accepted secondary prevention strategy available for sMM and MGUS progression. Future studies are required to combine increasing knowledge on risk factors and molecular pathogenesis with targeted agents to prevent progression.

    Smoldering multiple myeloma (SMM) is a pre-malignant condition with an inherent risk for progression to multiple myeloma (MM). The 2014 IMWG guidelines define smoldering multiple myeloma as a monoclonal gammopathy disorder with serum monoclonal protein (IgG or IgA) ≥30 g/L or urinary monoclonal protein ≥500 mg per 24 h and/or clonal bone marrow plasma cells 10-60 % without any myeloma-defining events or amyloidosis. The risk for progression of SMM to MM vary based on clinical, laboratory, imaging, and molecular characteristics. Observation, with periodic monitoring is the current standard of care for SMM. Over last few years, research advances in SMM have led to the delineation of newer risk factors for progression and identification of a "high-risk" group that would potentially benefit from early treatment. This review focuses on advances in the SMM risk-stratification model and recent clinical trials in this patient population.

    Full Text Available We report a case of a female with stage I infiltrating ductal carcinoma who received adjuvant therapy including trastuzumab. One year later she developed lytic lesions and was retreated with trastuzumab that was held after she developed symptomatic heart failure. Lytic lesions were attributed to relapse of breast cancer, and cardiac failure attributed to prior trastuzumab therapy. After complications necessitated multiple hospitalizations, a further workup revealed that the lytic lesions were not metastatic breast cancer but multiple myeloma. Her advanced multiple myeloma was associated with systemic amyloidosis involving gut and heart, which ultimately led to her demise. This report addresses the pitfalls of overlapping symptoms and the question of which patients with suspected metastatic disease should undergo a biopsy.

    Full Text Available Novel drugs such as bortezomib and high dose chemotherapy combined with stem cell transplantation improved the outcome of multiple myeloma patients in the past decade. However, multiple myeloma often remains incurable due to the development of drug resistance governed by the bone marrow micro-environment. Therefore targeting new pathways to overcome this resistance is needed. Histone deacetylase (HDAC inhibitors represent a new class of anti-myeloma agents. Inhibiting HDACs results in histone hyperacetylation and alterations in chromatine structure, which, in turn, cause growth arrest differentiation and/or apoptosis in several tumor cells. Here we summarize the molecular actions of HDACi as a single agent or in combination with other drugs in different in vitro and in vivo myeloma models and in (preclinical trials.

    Full Text Available The treatment of multiple myeloma (MM has changed dramatically in the past twenty years with the introduction of high-dose therapy plus autologous stem-cell transplantation (ASCT in younger patients and, more recently, of three novel agents (thalidomide, bortezomib, and lenalidomide. When conventional chemotherapy was the only available possibility, complete responses (CR were very rare and the objective of maintenance was to prolong remission duration by continuing the same type of treatment that induced the initial response. With recent therapeutic improvements, CR achievement becomes a realistic goal that, in most cases, is significantly correlated with the outcome (1. Therefore, both the nature and the impact of maintenance therapy have changed. Maintenance therapy is based currently on novel agents, and its objective is not only to control the clone but also to further decrease the tumor burden and improve the quality of response. A number of randomized studies show a benefit from maintenance therapy with novel agents (until now, mostly thalidomide, at least in terms of response rate and progression-free survival (PFS. However, there is still a debate as concerns the impact on overall survival (OS and the optimal administration of maintenance therapy.

    Full Text Available Multiple myeloma is a malignant proliferation of monoclonal plasma cells leading to clinical features that include hypercalcaemia, renal dysfunction, anaemia, and bone disease (frequently referred to by the acronym CRAB which represent evidence of end organ failure. Recent evidence has revealed myeloma to be a highly heterogeneous disease composed of multiple molecularly-defined subtypes each with varying clinicopathological features and disease outcomes. The major division within myeloma is between hyperdiploid and nonhyperdiploid subtypes. In this division, hyperdiploid myeloma is characterised by trisomies of certain odd numbered chromosomes, namely, 3, 5, 7, 9, 11, 15, 19, and 21 whereas nonhyperdiploid myeloma is characterised by translocations of the immunoglobulin heavy chain alleles at chromosome 14q32 with various partner chromosomes, the most important of which being 4, 6, 11, 16, and 20. Hyperdiploid and nonhyperdiploid changes appear to represent early or even initiating mutagenic events that are subsequently followed by secondary aberrations including copy number abnormalities, additional translocations, mutations, and epigenetic modifications which lead to plasma cell immortalisation and disease progression. The following review provides a comprehensive coverage of the genetic and epigenetic events contributing to the initiation and progression of multiple myeloma and where possible these abnormalities have been linked to disease prognosis.

    Smoldering multiple myeloma (SMM) is an asymptomatic disorder characterized by the presence of ≥ 30 g/l serum M-protein and/or ≥ 10% bone marrow plasma cell infiltration. The progression risk to active multiple myeloma (MM) is not uniform, and several prognostic parameters are useful for identifying patients at high risk of progression. A watch-and-wait approach has been the standard of care up to now. However, recently, it has been demonstrated that a subset of high-risk cases can benefit from early treatment with new drugs. In this editorial, we focus on SMM and evaluate the diagnostic work-up and the prognostic factors predicting progression to symptomatic MM. We also review the studies in which the role of early treatment has been evaluated for patients with SMM. After the update performed by the International Myeloma Working Group regarding MM diagnosis, it is now time to change the therapeutic paradigm for this disease. While "ultra high-risk" myeloma should now be considered as active MM, for low-risk patients the "watch-and-wait" strategy is still recommended. More caution is needed for the high-risk group: physicians should continue monitoring patients using every tool now available while waiting for results from ongoing trials that will establish if this group will benefit from an early intervention.

    Smoldering myeloma is an asymptomatic plasma cell dyscrasia with a heterogeneous propensity to progress to active myeloma. In order to investigate the biology of smoldering myeloma patients with high risk of progression, we analyzed the genomic characteristics by FISH, SNP-arrays and gene expression profile of a group of patients with high-risk smoldering myeloma included in a multicenter randomized trial. Chromosomal abnormalities detected by FISH and SNP-arrays at diagnosis were not associated to risk of progression to symptomatic myeloma. However, the overexpression of four SNORD genes (SNORD25, SNORD27, SNORD30 and SNORD31) was correlated with shorter time to progression (Psmoldering patients who progressed to symptomatic myeloma were sequentially analyzed, newly acquired lesions together with an increase in the proportion of plasma cells carrying a given abnormality were observed. These findings suggest that gene expression profiling is a valuable technique to identify smoldering myeloma patients with high risk of progression. (Clinical Trials NCT00443235).

    2016-04-01

    With the introduction of thalidomide and multi-agent chemotherapy in the treatment of multiple myeloma around 15years ago a strongly increased risk of venous thrombosis was observed. The occurrence of venous thrombosis in multiple myeloma is not only determined by the kind of treatment, but also by several other factors, including disease specific factors, patient-specific factors, changes in pro-and anticoagulant factors and fibrinolysis. Studies showed a prevalence of up to 25% in patients with newly diagnosed multiple myeloma. Therefore these patients nowadays receive prophylaxis with aspirin, low molecular weight heparin or warfarin in order to reduce the risk of venous thrombosis. It is however still debatable which patients should receive prophylaxis and what the best kind of prophylaxis is, considering both the risk of thrombosis and the risk of bleeding. In recent years several new anti-myeloma agents have been developed and investigated in large clinical studies. The risk of thrombosis using these new drugs seems less than with thalidomide and lenalidomide-based regimens.

    Full Text Available Multiple sclerosis (MS is the commonest cause of disability in young adults. While there is increasing choice and better treatments available for delaying disease progression, there are still, very few, effective symptomatic treatments. For many patients such as those with primary progressive MS (PPMS and those that inevitably become secondary progressive, symptom management is the only treatment available. MS related symptoms are complex, interrelated, and can be interdependent. It requires good understanding of the condition, a holistic multidisciplinary approach, and above all, patient education and empowerment.

Significant univariable risk factors for TTP were selected for multivariable Cox regression analyses. We found that both an M-protein ≥ 30g/l and immunoparesis significantly influenced......-high risk of transformation to MM. Using only immunoparesis and M-protein ≥ 30g/l, we created a scoring system to identify low, intermediate and high risk SMM.

    Since smoldering multiple myeloma (SMM) was first described over three decades ago based on a case series of six patients, its definition and our understanding of the entity have evolved considerably. The risk of progression to symptomatic myeloma (MM) varies greatly among individuals diagnosed with myeloma precursor disease. Epidemiologic, molecular, flow cytometric and radiological techniques have demonstrated that this transformation to MM from precursor states is not sudden but rather a continuous overlapping series of events with evidence of end-organ damage that could manifest in the earliest stages of disease. Contemporary antimyeloma therapies can yield rapid, deep, and durable responses with manageable toxicities, and molecular-cell-based measures are now available to rule out minimal residual disease. With this information, clinical studies with correlative measures can now be developed to test the fundamental hypothesis that intervention in early myeloma may provide a measurable clinical benefit to patients by either delaying progression or eradicating plasma cell clones. © 2013 John Wiley & Sons A/S.

    There have been major recent advancements in the understanding and management of multiple myeloma. Diagnostic criteria have been revised and former ultra-high-risk smoldering multiple myeloma is now considered multiple myeloma in need of treatment. Understanding clonal progression, evolution, and tides not only has helped elucidate the disease behavior but might help expand therapeutic choices in order to select appropriate treatment for patients. Unprecedented response rates with modern triplet induction therapies containing proteasome inhibitor and immunomodulators have made this approach standard for initial treatment. The US Food and Drug Administration approved four new drugs (two targeted antibodies and two oral agents) in 2015 in relapsed/refractory multiple myeloma and these drugs along with the other already-available drugs have now increased the choices of regimens. Even drugs without single-agent activity, such as panobinostat and elotuzumab, have an important role, especially in the proteasome inhibitor refractory setting. Recent studies done in the context of novel agent induction suggest that high-dose therapy followed by autologous transplant continues to improve response rates and progression-free survival, thus underscoring their role in transplant-eligible patients. Evolving paradigms in the treatment of multiple myeloma include newer promising immune approaches, such as adoptive cellular therapies, vaccines, or antibody-based immune manipulations. Though multiple myeloma is still considered incurable, it is clear that with the improved understanding of disease biology and clonal architecture of relapse combined with the availability of multi-targeted approaches, we are ever closer to a lasting cure or transformation into indolent and long-lasting disease courses or both.

    Two cases of oculomotor nerves involvement as uncommon initial manifestation of a parasellar extramedullary plasmacytoma are reported. The first patient presented with an isolated left VI cranial nerve palsy; the second one had an incomplete left III cranial nerve palsy. In both cases clinical investigation and computed tomography revealed an intracranial plasmacytoma associated with multiple myeloma. It is important to underline the difference between an intracranial extramedullary plasmacytoma and a plasmacytoma associated with multiple myeloma. In fact the absence of a general associated illness should show a most favourable course.

    We present a patient with multiple myeloma whose only presenting symptom was stridor caused by a subglottic stenosis. Biopsy suggested the presence of amyloid which prompted immunological investigations that showed hypogammaglobulinaemia and the presence of Bence Jones proteinuria at 0.93 g/24 hours. Further investigation demonstrated a 15 per cent plasma cell infiltrate into the bone marrow and a lytic lesion in the mid-shaft of the right femur. Chemotherapy and localized radiotherapy were commenced. This is a most unusual presentation of multiple myeloma and shows that immunoglobulin profiles should be properly investigated in such cases.

    To determine the frequency and pattern of blood clotting disorders in patients with multiple myeloma (MM) and to evaluate the adequacy of preventive anticoagulant or antiaggregant therapy. The prospective study conducted at the Department for High-Dose Chemotherapy and Bone Marrow Transplantation, Hematology Research Center, Ministry of Health of the Russian Federation, in March 2012 to May 2013, enrolled 25 patients (13 men and 12 women) aged 29-72 years (median age 54 years) with new-onset MM. The latter was staged using the Durie-Salmon classification: Stages I, II, and III were determined in 2, 10, and 13 patients, respectively. Seven patients were found to have renal dysfunction (which corresponded to Substage B). The hemostasis was evaluated from the results of the following tests: activated partial thromboplastin time (APTT), thrombin time (TT), Xlla-dependent fibrinolysis time, Quick prothrombin index, international normalized ratio (INR), and fibrinogen and D-dimer concentrations. The investigators used new hemostatic techniques, such as thrombin generation test, thromboelastography, as well as thrombodynamics, a novel method to determine the characteristics of spatial clot growth. Induction therapy was performed using the PAD and VCD regimens. Thromboses were prevented by using 24-hour infusion of unfractionated heparin (500 U/hr) or by administering aspirin (100 mg/day). Hypercoagulability was identified in 17 (68%) patients. Eleven (44%) patients had elevated D-dimer concentrations. The level of D-dimer was statistically significantly positively correlated with the endogenous thrombin potential and the amount of beta2-microglobulin. The thrombodynamic technique revealed an inverse relationship between the level of paraprotein and the optimal density of a fibrin clot. A thrombotic episode was seen in one elderly (71-year-old) patient after aspirin discontinuation during long-term immobilization. Nearly 50% of the primary patients with MM were ascertained

    Mutiple mieloma (MM) cells are rarely found in extramedullary sites. The sites of extramedullary dissemination reported in the literature are spleen, liver, lymph nodes, kidneys, thyroid gland, adrenal gland, ovary, tests, lung, pleura, pericardium, intestinal tract and skin. We report a case in which the myeloma was diagnosed after we discovered the presence of monoclonal plasma cells in the bronchoalveolar lavage fluid (BAL). Matherial and method: a case in which diagnosis was established from bronchoalveolar lavage (BAL) fluid demonstrating the presence of monoclonal plasma cells in Craiova Pneumology Departament. Analysis of BAL fluid for the presence of plasma cells and for cytoplasmic immunoglobulin DNA provides a noninvasive means of establishing the diagnosis. Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature.

    Full Text Available Agnieszka Blum, Despina Bazou, Peter O’Gorman Department of Hematology, Mater Misericordiae University Hospital, Dublin, UK Abstract: Smoldering multiple myeloma (SMM is an asymptomatic plasma cell proliferative disorder associated with risk of progression to symptomatic multiple myeloma (MM or amyloidosis. In comparison to monoclonal gammopathy of undetermined significance (MGUS, SMM has a much higher risk of progression to MM. Thanks to advances in our understanding of the risk factors, the subset of patients with ultra-high risk of progression to MM (80%–90% at 2 years has been identified. The revision of the diagnostic criteria resulted in changes in the management of this cohort of patients. In contrast to the management guidelines for MGUS patients, SMM patients need to be studied more intensively in order to identify biomarkers necessary for accurate risk stratification. In this review, we focus on the risk of progression from SMM to MM, as well as the influence of early treatment on overall survival, time to progression and quality of life.

    Smoldering myeloma is a heterogeneous clinical entity where a subset of patients has an indolent course of disease that mimics monoclonal gammopathy of undermined significance, whereas others have a more aggressive course that has been described as "early myeloma." It is defined as either serum M-protein ≥ 3 g/L or ≥ 10% monoclonal plasma cells in the bone marrow. There are currently no molecular factors to differentiate risks of progression for these patients. Current recommendations of therapy continue to be patient observation or patient enrollment in clinical trials. However, new definitions of active multiple myeloma recently agreed upon by the International Myeloma Working Group may alter the timing of therapy. On the basis of emerging data of therapy in these patients, it seems reasonable to believe that future recommendations for therapy of patients with smoldering myeloma will become an increasingly important topic. In this article, we review the current knowledge of this disease and risk factors associated with progression. We also examine biological insights and alterations that occur in the tumor clone and the surrounding bone marrow niche. Finally, we review clinical trials that have been performed in these patients and provide recommendations for follow-up of patients with this unique disease entity. © 2014 by The American Society of Hematology.

    2014-06-01

    Emerging clinical trial data support treatment of high-risk smoldering multiple myeloma (SMM) upon diagnosis, and not only at the time of progression to symptomatic complications (multiple myeloma). Early detection of bone and/or bone marrow involvement by sensitive imaging modalities may help define SMM patients at a high risk of progression. Current (2011) consensus guidelines recognize skeletal survey as a cornerstone modality for assessment of bone involvement at initial diagnosis and during follow-up of SMM. Skeletal survey has severe limitations related to underdetection of bone lesions and also provides no information on bone marrow abnormalities. Modern imaging strategies such as fluorodeoxyglucose positron-emission tomography/CT (FDG PET/CT) and MRI, in conjunction with functional innovations, provide improved estimates of global abnormalities in the bone marrow and bone compartments. These methods have the potential to objectively quantify early transformation from SMM to multiple myeloma. Although frequently used for staging and risk prognostication in multiple myeloma, modern imaging techniques have only been evaluated to a limited extent in SMM. Scant data in SMM indicate the prognostic value of two or more MRI-detected focal bone marrow abnormalities, which, if present, predict rapid progression to multiple myeloma. Data evaluating the role of FDG PET/CT in detecting early bone marrow abnormalities as an aid to predicting risk or directing treatment in SMM is currently lacking. The superior specificity and sensitivity of modern imaging techniques compared to skeletal survey suggest that these should have a place in standard practice management of patients at a high risk of SMM progression. The model imaging of the future should be an all-in-one strategy offering high diagnostic performance for bone marrow abnormalities and low-volume bone lesions, as well as allowing monitoring by minimizing radiation exposure and the need for contrast agents.

    Full Text Available Multiple myeloma is the second most common hematologic malignancy. The treatment of this disease has changed considerably over the last two decades with the introduction to the clinical practice of novel agents such as proteasome inhibitors and immunomodulatory drugs. Basic research efforts towards better understanding of normal and missing immune surveillence in myeloma have led to development of new strategies and therapies that require the engagement of the immune system. Many of these treatments are under clinical development and have already started providing encouraging results. We, for the second time in the last two decades, are about to witness another shift of the paradigm in the management of this ailment. This review will summarize the major approaches in myeloma immunotherapies.

    2008-05-01

    The last decade has seen rapid evolution in the management of multiple myeloma. Cytogenetic, molecular, and proteomic techniques have led to a better understanding of the pathophysiology and prognostic markers of this heterogeneous malignancy. New immunomodulatory drugs, such as lenalidomide, which interrupt myeloma growth and survival pathways have entered into clinical usage. Combined with dexamethasone, oral lenalidomide has proved to be highly effective in patients whose disease has become resistant to conventional therapy. Currently, several clinical trials are ongoing in order to define the optimal use of this new agent and its combinations across the spectrum of patients with myeloma. Whether the ultimate outcome of future research will be a single-treatment solution for all patients, or whether treatments will become better-tailored to the individual (based on prognostic markers and pre-existing co-morbidities) has yet to be determined.

  14. Implications of Heterogeneity in Multiple Myeloma

    2014-01-01

    Full Text Available Multiple myeloma is the second most common hematologic malignancy in the world. Despite improvement in outcome, the disease is still incurable for most patients. However, not all myeloma are the same. With the same treatment, some patients can have very long survival whereas others can have very short survival. This suggests that there is underlying heterogeneity in myeloma. Studies over the years have revealed multiple layers of heterogeneity. First, clinical parameters such as age and tumor burden could significantly affect outcome. At the genetic level, there are also significant heterogeneity ranging for chromosome numbers, genetic translocations, and genetic mutations. At the clonal level, there appears to be significant clonal heterogeneity with multiple clones coexisting in the same patient. At the cell differentiation level, there appears to be a hierarchy of clonally related cells that have different clonogenic potential and sensitivity to therapies. These levels of complexities present challenges in terms of treatment and prognostication as well as monitoring of treatment. However, if we can clearly delineate and dissect this heterogeneity, we may also be presented with unique opportunities for precision and personalized treatment of myeloma. Some proof of concepts of such approaches has been demonstrated.

    Recently, a report has suggested the efficacy and safety of thalidomide in refractory multiple myeloma. In an attempt to assess the efficacy and tolerance of thalidomide in advanced multiple myeloma (on behalf of the Intergroupe Franchophone dy Myelome (IFM)), we report the preliminary experience of the IFM with this drug. Patients with advanced multiple myeloma (n=27) were treated with an oral dose of thalidomide (median 400 mg/day). At the start of treatment, all patients had active disease and 20 patients had received at least one autologous transplantation. Median follow-up was 105 days from the first administration. The serum and/or urine levels of the M-component were reduced by at least 75% in four patients including one patient with a >90% reduction, by at least 50% in five patients and by at least 25% in three patients, giving a total response rate of 45% (12 out of 27 patients). Nine patients had stable disease and six patients had progressed disease. Short-term side-effects of thalidomide were generally moderate. This study confirms that thalidomide is an effective agent in patients with advanced myeloma.

    Full Text Available Multiple myeloma (MM is a plasma cell disorder associated with clonal proliferation of plasma cells. Nonsecretory multiple myeloma (NSMM is a rare variant of MM and accounts for approximately 1% to 5% of all cases. It is defined as symptomatic myeloma without detectable monoclonal immunoglobulin on serum or urine electrophoresis. This variant usually poses a diagnostic challenge to the clinician. We present a 60-year-old Nigerian man who was investigated extensively for bone pain, weight loss, and anaemia. He was eventually diagnosed as having nonsecretory multiple myeloma based on histology and immunohistochemistry results of bone marrow trephine biopsy. He is currently being managed with bortezomib, doxorubicin, and thalidomide, as well as zoledronic acid. He is also on anticoagulation. He continues to show remarkable clinical improvement. We describe this case report and literature review for better awareness amongst medical practitioners and pathologists.

    For patients with smoldering multiple myeloma, the standard of care is observation until symptoms develop. However, this approach does not identify high-risk patients who may benefit from early intervention. In this randomized, open-label, phase 3 trial, we randomly assigned 119 patients with high-risk smoldering myeloma to treatment or observation. Patients in the treatment group received an induction regimen (lenalidomide at a dose of 25 mg per day on days 1 to 21, plus dexamethasone at a dose of 20 mg per day on days 1 to 4 and days 12 to 15, at 4-week intervals for nine cycles), followed by a maintenance regimen (lenalidomide at a dose of 10 mg per day on days 1 to 21 of each 28-day cycle for 2 years). The primary end point was time to progression to symptomatic disease. Secondary end points were response rate, overall survival, and safety. After a median follow-up of 40 months, the median time to progression was significantly longer in the treatment group than in the observation group (median not reached vs. 21 months; hazard ratio for progression, 0.18; 95% confidence interval [CI], 0.09 to 0.32; Psmoldering myeloma delays progression to active disease and increases overall survival.

    Full Text Available Multiple myeloma is a malignant neoplastic disease, characterized by uncontrolled proliferation and accumulation of plasma cells in the bone marrow, which is usually connected with production of a monoclonal protein. It is the second most common hematologic malignancy. It constitutes approximately 1% of all cancers and 10% of hematological malignancies. Despite the huge progress that has been made in the treatment of multiple myeloma in the past 30 years including the introduction of new immunomodulatory drugs and proteasome inhibitors, it is still an incurable disease. According to current data, the five-year survival rate is 45%. Multiple myeloma is a very heterogeneous disease with a very diverse clinical course, which is expressed by differences in effectiveness of therapeutic strategies and ability to develop chemoresistance. This diversity implies the need to define risk stratification factors that would help to create personalized and optimized therapy and thereby improve treatment outcomes. Prognostic markers that aim to objectively evaluate the risk of a poor outcome, relapse and the patient’s overall outcome are useful for this purpose. The existing, widely used prognostic classifications, such as the Salmon-Durie classification or ISS, do not allow for individualization of treatment. As a result of the development of diagnostic techniques, especially cytogenetics and molecular biology, we were able to discover a lot of new, more sensitive and specific prognostic factors. The paper presents recent reports on the role of molecular, cytogenetic and biochemical alterations in pathogenesis and prognosis of the disease.

    Although many studies have been carried out on monoclonal gammopathy of unknown significances (MGUS), smoldering multiple myeloma (SMM), and multiple myeloma (MM), their classification and underlying pathogenesis are far from elucidated. To discover the relationships among MGUS, SMM, and MM at the transcriptome level, differentially expressed genes in MGUS, SMM, and MM were identified by the rank product method, and then co-expression networks were constructed by integrating the data. Finally, a pathway-network was constructed based on Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and the relationships between the pathways were identified. The results indicated that there were 55, 78, and 138 pathways involved in the myeloma tumor developmental stages of MGUS, SMM, and MM, respectively. The biological processes identified therein were found to have a close relationship with the immune system. Processes and pathways related to the abnormal activity of DNA and RNA were also present in SMM and MM. Six common pathways were found in the whole process of myeloma tumor development. Nine pathways were shown to participate in the progression of MGUS to SMM, and prostate cancer was the sole pathway that was involved only in MGUS and MM. Pathway-network analysis might provide a new indicator for the developmental stage diagnosis of myeloma tumors.

    BACKGROUND: Monoclonal antibodies are promising anti-myeloma treatments. As immunoglobulins, monoclonal antibodies have the potential to be identified by serum protein electrophoresis (SPE) and immunofixation electrophoresis (IFE). Therapeutic antibody interference with standard clinical SPE...... and IFE can confound the use of these tests for response assessment in clinical trials and disease monitoring. METHODS: To discriminate between endogenous myeloma protein and daratumumab, a daratumumab-specific immunofixation electrophoresis reflex assay (DIRA) was developed using a mouse anti......-treated patient samples. The DIRA limit of sensitivity was 0.2 g/L daratumumab, using spiking experiments. Results from DIRA were reproducible over multiple days, operators, and assays.

    The novel criteria for the diagnosis of symptomatic multiple myeloma have revealed the value of modern imaging for the management of patients with myeloma. Whole-body low-dose CT (LDCT) has increased sensitivity over conventional radiography for the detection of osteolytic lesions, and several myeloma organizations and institutions have suggested that whole-body LDCT should replace conventional radiography for the work-up of patients with myeloma. MRI is the best imaging method for the depiction of marrow infiltration by myeloma cells. Whole-body MRI (or at least MRI of the spine and pelvis if whole-body MRI is not available) should be performed for all patients with smoldering multiple myeloma with no lytic lesions to look for occult disease, which may justify treatment. In addition, MRI accurately illustrates the presence of plasmacytomas, spinal cord, and/or nerve compression for surgical intervention or radiation therapy; it is also recommended for the work-up of solitary bone plasmacytoma, and it may distinguish malignant from benign fractures (which is very important in cases of patients in biochemical remission with no other signs of progression). Diffusion weighted imaging (DWI) seems to improve MRI diagnosis in patients with myeloma. PET/CT is a functional imaging technique, more sensitive than conventional radiography for the detection of lytic lesions, which probably allows better definition of complete response and minimal residual disease compared with all other imaging methods. PET/CT has shown the best results in the follow-up of patients with myeloma and has an independent prognostic value both at diagnosis and following treatment. PET/CT can also be used for the work-up of solitary bone plasmacytoma and nonsecretory myeloma.

    Smoldering multiple myeloma (SMM) is an asymptomatic clonal plasma cell disorder and bridges monoclonal gammopathy of undetermined significance to multiple myeloma (MM), based on higher levels of circulating monoclonal immunoglobulin and bone marrow plasmocytosis without end-organ damage. Until a Spanish study reported fewer MM-related events and better overall survival among patients with high-risk SMM treated with lenalidomide and dexamethasone, prior studies had failed to show improved survival with earlier intervention, although a reduction in skeletal-related events (without any impact on disease progression) has been described with bisphosphonate use. Risk factors have now been defined, and a subset of ultra-high-risk patients have been reclassified by the International Myeloma Working Group as MM, and thus will require optimal MM treatment, based on biomarkers that identify patients with a >80% risk of progression. The number of these redefined patients is small (∼10%), but important to unravel, because their risk of progression to overt MM is substantial (≥80% within 2 years). Patients with a high-risk cytogenetic profile are not yet considered for early treatment, because groups are heterogeneous and risk factors other than cytogenetics are deemed to weight higher. Because patients with ultra-high-risk SMM are now considered as MM and may be treated as such, concerns exist that earlier therapy may increase the risk of selecting resistant clones and induce side effects and costs. Therefore, an even more accurate identification of patients who would benefit from interventions needs to be performed, and clinical judgment and careful discussion of pros and cons of treatment initiation need to be undertaken. For the majority of SMM patients, the standard of care remains observation until development of symptomatic MM occurs, encouraging participation in ongoing and upcoming SMM/early MM clinical trials, as well as consideration of bisphosphonate use in

    2017-12-08

    In recent years, several new drugs have been approved for the treatment of multiple myeloma. Many of these newer drugs are highly efficacious and less toxic than older chemotherapy drugs. In 2014, the diagnostic criteria for multiple myeloma were revised. The intent with the new criteria was to identify patients who require therapy at an earlier stage than at manifestation of organ complications. A subset of patients who were previously defined as having high-risk smoldering multiple myeloma was redefined as having multiple myeloma. In this context, it is logical to raise questions regarding the optimal clinical management of patients who are diagnosed with smoldering multiple myeloma in the current era. When is the optimal time to start therapy? Do the clinical trajectories for patients suggest there are distinct sub-entities hidden in the current category of smoldering multiple myeloma? How can we move the field forward from here? This paper reviews and dissects data and models on the topics of clinical features, underlying biology, and early treatment trials in smoldering multiple myeloma. The text highlights assumptions, facts, and gaps in the literature. As indicated in the title of the paper, the recurrent theme of the text is this: shall we treat smoldering multiple myeloma in the near future? © 2016 by The American Society of Hematology.

    2008-01-01

    Full Text Available Multiple myeloma is a malignant plasma cell proliferative disorder that produces a monoclonal immunoglobulin protein. The skin involvement and the development of bullous disease are rarely seen features in multiple myeloma. We present a 55-year-old man with a longstanding, large, tense bullous eruption and hypertrophic scars over his body accompanied recently with weight loss and fatique. He had no response to the previous treatments, which included oral glucocorticoids and dapsone. Histologic examination of the lesions revealed subepidermal bullae, while no immunoflourescence staining was observed. In a further detailed labarotory examination, multiple myeloma was detected. After the treatment of multiple myeloma with chemotherapy, the lesions regressed. Patients with longstanding, recurrent, unusual bullous eruption should be investigated for the development of multiple myeloma.

    Full Text Available Multiple myeloma is a systemic B-cell lymphoproliferative disease that causes osteolytic lesions in the vertebra, ribs, pelvic bone, skull and jaw. Rarely jaw lesions are seen as the first sign in multiple myeloma. This is a case report with follow up of a 57-year-old female patient, previously treated for osteoporosis, who presented with a swelling of the jaw. On radiographic examination, she was found to have osteolytic lesions in the mandible and skull bones. These conventional aids led to the diagnosis of multiple myeloma thereby proving that the osteoporotic lesions were a part of the spectrum of multiple myeloma. The patient underwent chemotherapy and is currently on follow-up. This case report emphasizes the importance of early diagnosis of multiple myeloma in the jaw using readily available technologies and illustrates the contribution that oral assessment can provide.

On a cellular level, the disease is characterized by complex interactions between tumor cells and the surrounding bone marrow microenvironment. Understanding of the relationship between malignant plasma cells and the microenvironment has sparked ongoing efforts to develop targeted therapeutic agents for treatment of this disease. The successful development of the first-in-class small-molecule proteasome inhibitor bortezomib occurred as a result of these efforts. This review focuses on the rationale for bortezomib therapy in the treatment of patients with newly diagnosed and relapsed MM, important treatment-related side effects, and future directions for use of bortezomib and other, emerging proteasome inhibitors.Keywords: multiple myeloma, bortezomib, stem cell transplantation, peripheral neuropathy

    Multiple myeloma (MM) is a hematologic malignancy of monoclonal plasma cells which remains incurable despite recent advances in therapies. The presence of cancer stem cells (CSCs) has been demonstrated in many solid and hematologic tumors, so the idea of CSCs has been proposed for MM, even if MM CSCs have not been define yet. The existence of myeloma CSCs with clonotypic B and clonotypic non B cells was postulated by many groups. This review aims to focus on these distinct clonotypic subpopulations and on their ability to develop and sustain MM. The bone marrow microenvironment provides to MM CSCs self-renewal, survival and drug resistance thanks to the presence of normal and cancer stem cell niches. The niches and CSCs interact each other through adhesion molecules and the interplay between ligands and receptors activates stemness signaling (Hedgehog, Wnt and Notch pathways). MM CSCs are also supposed to be responsible for drug resistance that happens in three steps from the initial cancer cell homing microenvironment-mediated to development of microenvironment-independent drug resistance. In this review, we will underline all these aspects of MM CSCs.

Initial symptoms in most cases described in the literature include chest and lumbar pain, paresthesia, paraplegia, general weakness and renal failure. We report a case of isolated sixth nerve palsy causing diplopia as the presenting sign of multiple myeloma. Awareness of such a rare clinical presentation - especially when the existence of multiple myeloma is ignored after visualization of a cranial mass with magnetic resonance imaging (MRI) and computerized tomography (CT)--can prevent unnecessary surgical intervention and delay the appropriate treatment.

    Multiple myeloma is a plasma cell dyscrasia producing bone lytic lesions. In recent years, a wide spectrum of therapeutic approaches are available to treat the disease: an accurate therapy assessment has, therefore, become of utmost importance. In this field, imaging is becoming a cornerstone, especially in association with clinical parameters. Among imaging procedures, FDG PET/CT is recognized to provide reliable information, achieved in a very safe and fast procedure. The literature has produced very concordant results from different groups assessing the value of FDG PET/CT as a prognostic factor in general and in therapy assessment, but some issues remain regarding a standardization of image interpretation especially in borderline cases. So far, no data regarding nor other imaging compounds and the use of hybrid tomographs PET/MR are available to define therapy assessment in PET. (orig.)

    Novel therapies hold promise for high-risk smoldering multiple myeloma (SMM). Recent studies suggest that modern combination approaches can be options for high-risk SMM to obtain deep molecular responses with favorable toxicity profiles. Although pioneering treatment trials based on small numbers of patients suggest progression-free and overall survival benefits, application of the data to real-life practice remains to be validated. Therapeutic modulation of disease tempo, disease burden, clonal evolution, and tumor microenvironment in SMM remains to be understood and calls for reliable biomarkers reflective of disease biology. Here, we review studies that open a new management platform for SMM, address ongoing dilemmas in practice and under investigation, and highlight emerging scientific questions in the era of SMM treatment. © 2014 by American Society of Clinical Oncology.

    2014-01-01

    Full Text Available Multiple Myeloma (MM is a systemic hematologic disease due to uncontrolled proliferation of monoclonal plasma cells (PC in bone marrow (BM. Emerging in other solid and liquid cancers, the host immune system and the microenvironment have a pivotal role for PC growth, proliferation, survival, migration, and resistance to drugs and are responsible for some clinical manifestations of MM. In MM, microenvironment is represented by the cellular component of a normal bone marrow together with extracellular matrix proteins, adhesion molecules, cytokines, and growth factors produced by both stromal cells and PC themselves. All these components are able to protect PC from cytotoxic effect of chemo- and radiotherapy. This review is focused on the role of immunome to sustain MM progression, the emerging role of myeloid derived suppressor cells, and their potential clinical implications as novel therapeutic target.

    Multiple myeloma (MM) is a plasma cell neoplasm that affects elderly individuals with two-thirds of patients over 65 years at diagnosis. However, data available are derived from clinical trials conducted in younger patients. Fewer studies investigated treatment options in the elderly. This review summarizes the clinical outcomes and toxicities associated with therapeutic regimens in older patients including doublet, triplet and high dose therapyin newly diagnosed patients and relapsed patients with MM. We highlight the importance of an approach tailored to individuals, incorporates the geriatric frailty assessment, considers comorbiditiess and commits to early recognition and management of toxicities ranging from myelosuppression to polypharmacy. To date, no trial has prospectively investigated a tailored treatment paradigm in older patients based on frailty and/or comorbidities. As the population ages, the proportion of MM patients with advanced age will grow. Studies are indicated to determine optimal treatment approaches in this increasingly heterogeneous geriatric population.

    Full Text Available Multiple myeloma (MM is a disorder of terminally differentiated plasma cells characterized by clonal expansion in the bone marrow (BM. It is the second-most common hematologic malignancy. Despite significant advances in therapeutic strategies, MM remains a predominantly incurable disease emphasizing the need for the development of new treatment regimens. Immunotherapy is a promising treatment modality to circumvent challenges in the management of MM. Many novel immunotherapy strategies, such as adoptive cell therapy and monoclonal antibodies, are currently under investigation in clinical trials, with some already demonstrating a positive impact on patient survival. In this review, we will summarize the current standards of care and discuss major new approaches in immunotherapy for MM.

    We report a case of multiple myeloma that presented as a fluctuating sixth cranial nerve palsy in the absence of widespread signs of systemic disease. A 63-year-old woman presented with horizontal diplopia of two weeks duration that subjectively changed over time. Ocular examination showed a fluctuating sixth nerve palsy. A computed tomography (CT) scan of the brain showed multiple, enhancing, soft tissue, mass-like lesions involving the left cavernous sinus and the apex of both petrous bones. Based on bone marrow biopsy and hematologic findings, she was diagnosed with multiple myeloma. Multiple myeloma may be included in the differential diagnosis of a fluctuating sixth nerve palsy, and although ophthalmic signs are rare and generally occur late in the course of multiple myeloma, they can still be its first signs.

    2018-01-27

    Background: Multiple myeloma (MM) is a neoplastic plasma cell disorder characterized by clonal proliferation of plasma cells in the bone marrow. Diverse hemostatic abnormalities have been reported in patients with myeloma which predispose to bleeding and also thrombosis. Methods: Complete blood count, biochemical parameters and parameters of hemostasis i.e. platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), factor VIII assay results, plasma fibrinogen, D-dimer and lupus anticoagulant, were assessed in 29 MM patients and 30 age matched controls. Results: The most frequent abnormal screening parameter was APTT. Of the six indicative of a bleeding tendency i.e. thrombocytopenia, prolonged PT, APTT, TT, reduced plasma fibrinogen and factor VIII, at least one was abnormal in 8 (27.6%) patients. Of the four prothrombotic markers, lupus anticoagulant, D-dimer, elevated factor VIII and plasma fibrinogen, one or more marker was present in 24 (82.7%). D-dimer was the most common prothrombotic marker, being elevated in 22 (75.9%) patients. One or more laboratory parameter of hemostasis was abnormal in all 29 (100%) patients. Though thrombotic complications are reported to be less frequent as compared to hemorrhagic manifestations, one or more marker of thrombosis was present in 24 (82.7%) patients. Conclusion: This study provided laboratory evidence of hemostatic dysfunction which may be associated with thrombotic or bleeding complications at diagnosis in all MM patients. Hence, screening for these abnormalities at the time of diagnosis should help improved prognosis in such cases. Creative Commons Attribution License

  1. Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma: a review of the current understanding of epidemiology, biology, risk stratification, and management of myeloma precursor disease.

    Agarwal, Amit; Ghobrial, Irene M

    2013-03-01

    The term monoclonal gammopathy of undetermined significance (MGUS) was coined in 1978. The recent advances in our knowledge about MGUS and smoldering multiple myeloma (SMM) have helped us better understand the pathogenesis of myeloma. It seems that myeloma evolves from a precursor state in almost all cases. We do not completely understand the multistep process from the precursor state to myeloma, but studies like whole genome sequencing continue to improve our understanding of this process. The process of transformation may not be linear acquisition of changes, but rather a branched heterogeneous process. Clinical features that are prognostic of rapid transformation have been identified, but no specific molecular markers have been identified. Even with recent advances, multiple myeloma remains an incurable disease in the vast majority, and intervening at the precursor state provides a unique opportunity to alter the natural history of the disease. A limitation is that a vast majority of patients with precursor disease, especially low-risk MGUS, will never progress to myeloma in their lifetime, and treating these patients is not only unnecessary but may be potentially harmful. The challenge is to identify a subset of patients with the precursor state that would definitely progress to myeloma and in whom interventions will have a meaningful impact. As our understanding of the molecular and genetic processes improves, these studies will guide the selection of high-risk patients more appropriately and ultimately direct a tailored management strategy to either delay progression to symptomatic myeloma or even "cure" a person at this premalignant stage. ©2012 AACR.

    Full Text Available Multiple myeloma is considered a hypercoagulable state due to several mechanisms such as the increased IL-6 and immunoglobulins production, the defective fibrinolytic mechanism, and the acquired resistance to activated protein C that are involved in the pathogenesis and clinical futures of the disease. We describe a case of a female patient who presented to the hospital with pulmonary embolism as the first manifestation of the hypercoagulability of multiple myeloma.

    To describe the preferences for participation in decision making of older adult patients newly diagnosed with symptomatic myeloma and to explore the association between sociodemographic variables and decisional role preferences. Descriptive, cross-sectional design. Participants' homes and two large academic cancer centers in Seattle, WA, and Chicago, IL. A convenience sample of 20 older adults (60 years of age and older) with symptomatic myeloma diagnosed within the past six months. The Control Preferences Scale was administered followed by an in-person, one-time, semistructured interview. Role preferences for participation in treatment decision making, age, gender, race, work status, personal relationship status, education, and income. Fifty-five percent of the participants preferred a shared role with the physician and 40% preferred to make the decisions after seriously considering the opinion of their physicians. Only one participant preferred to leave the decision to the doctor, as long as the doctor considered the patient's treatment preferences. The study findings indicate that older adults newly diagnosed with myeloma want to participate in treatment decision making. Oncology nurses must respect the patient's desired role preference and oncology clinicians must listen to the patient and allow him or her to be autonomous in making treatment decisions. Nurses and other oncology clinicians can elicit a patient's preferred level of participation in treatment decision making. Oncology nurses can make sure patients receive disease- and treatment-related information, encourage them to express their decisional role preference to the physician, develop a culture of mutual respect and value their desire for autonomy for treatment decision making, acknowledge that the right to make a treatment choice belongs to the patient, and provide support during treatment decision making throughout the care continuum.

  6. Monoclonal Antibody: A New Treatment Strategy against Multiple Myeloma

    2017-11-01

    Full Text Available 2015 was a groundbreaking year for the multiple myeloma community partly due to the breakthrough approval of the first two monoclonal antibodies in the treatment for patients with relapsed and refractory disease. Despite early disappointments, monoclonal antibodies targeting CD38 (daratumumab and signaling lymphocytic activation molecule F7 (SLAMF7 (elotuzumab have become available for patients with multiple myeloma in the same year. Specifically, phase 3 clinical trials of combination therapies incorporating daratumumab or elotuzumab indicate both efficacy and a very favorable toxicity profile. These therapeutic monoclonal antibodies for multiple myeloma can kill target cells via antibody-dependent cell-mediated cytotoxicity, complement-dependent cytotoxicity, and antibody-dependent phagocytosis, as well as by direct blockade of signaling cascades. In addition, their immunomodulatory effects may simultaneously inhibit the immunosuppressive bone marrow microenvironment and restore the key function of immune effector cells. In this review, we focus on monoclonal antibodies that have shown clinical efficacy or promising preclinical anti-multiple myeloma activities that warrant further clinical development. We summarize mechanisms that account for the in vitro and in vivo anti-myeloma effects of these monoclonal antibodies, as well as relevant preclinical and clinical results. Monoclonal antibody-based immunotherapies have already and will continue to transform the treatment landscape in multiple myeloma.

    2015-01-01

    Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure.

  9. Leukemia, multiple myeloma, and malignant lymphoma

    Excess risk of leukemia among atomic bomb (A-bomb) survivors increased with radiation dose in Hiroshima and Nagasaki. The incidence of all types of leukemia, except chronic lymphocytic leukemia, has increased among A-bomb survivors. However, chronic myelogenous leukemia (CML) is thought to be the most characteristic type of the A-bomb induced leukemias. The highest risk of leukemia among A-bomb survivors was recognized in 1951 and has not yet disappeared in survivors in Hiroshima. Excess risk of leukemia in the younger age at time of bomb (ATB) groups appeared early; however, in older age ATB groups it appeared much later especially among Hiroshima survivors. In both cities the effect of radiation exposure on the occurrence of CML was more clearly observable in the younger age ATB groups and occurred more frequently in Hiroshima. Leukemia among individuals exposed in utero and children of A-bomb survivors has not increased significantly. The relationship between radiation induced leukemia and chromosome abnormalities is discussed. Twenty years after the A-bomb, the risk of multiple myeloma (MM) increased among survivors aged 20-59 years ATB. Non-Hodgkin's malignant lymphoma also increased among A-bomb survivors and showed roughly the same tendency as MM

  10. Antibody-Based Therapies in Multiple Myeloma

    Directory of Open Access Journals (Sweden)

    Yu-Tzu Tai

    2011-01-01

    Full Text Available The unmet need for improved multiple myeloma (MM therapy has stimulated clinical development of monoclonal antibodies (mAbs targeting either MM cells or cells of the bone marrow (BM microenvironment. In contrast to small-molecule inhibitors, therapeutic mAbs present the potential to specifically target tumor cells and directly induce an immune response to lyse tumor cells. Unique immune-effector mechanisms are only triggered by therapeutic mAbs but not by small molecule targeting agents. Although therapeutic murine mAbs or chimeric mAbs can cause immunogenicity, the advancement of genetic recombination for humanizing rodent mAbs has allowed large-scale production and designation of mAbs with better affinities, efficient selection, decreasing immunogenicity, and improved effector functions. These advancements of antibody engineering technologies have largely overcome the critical obstacle of antibody immunogenicity and enabled the development and subsequent Food and Drug Administration (FDA approval of therapeutic Abs for cancer and other diseases.

  12. Targeting the Pim kinases in multiple myeloma.

    LENUS (Irish Health Repository)

    Keane, N A

    2015-07-17

    Multiple myeloma (MM) is a plasma cell malignancy that remains incurable. Novel treatment strategies to improve survival are urgently required. The Pims are a small family of serine\\/threonine kinases with increased expression across the hematological malignancies. Pim-2 shows highest expression in MM and constitutes a promising therapeutic target. It is upregulated by the bone marrow microenvironment to mediate proliferation and promote MM survival. Pim-2 also has a key role in the bone destruction typically seen in MM. Additional putative roles of the Pim kinases in MM include trafficking of malignant cells, promoting oncogenic signaling in the hypoxic bone marrow microenvironment and mediating resistance to therapy. A number of Pim inhibitors are now under development with lead compounds entering the clinic. The ATP-competitive Pim inhibitor LGH447 has recently been reported to have single agent activity in MM. It is anticipated that Pim inhibition will be of clinical benefit in combination with standard treatments and\\/or with novel drugs targeting other survival pathways in MM.

  13. Multiple Myeloma in a Patient with Acromegaly

    2015-03-01

    Full Text Available Acromegaly is a slowly progressing condition resulting from excess growth hormone (GH, generally caused by a GH-secreting pituitary adenoma. Cancer is the third most common cause of mortality in patients with acromegaly, and insulin-like growth factor 1 (IGF-1 is known to influence tumor formation by increasing cell proliferation and inhibiting apoptosis. Multiple myeloma (MM is a plasma cell neoplasm, and previous studies have suggested the possible role of IGF-1 in its development of MM. However, no cases of acromegaly accompanied with MM have been reported in Asia to date. We here report the case of a 58-year-old woman with acromegaly accompanied with MM who presented with longstanding acromegalic manifestations resulting from a GH-secreting pituitary adenoma and also exhibited anemia, a reversed albumin/globulin ratio, and plasmacytosis on bone marrow examination. Because IGF-1 has been suggested to play an important role in the development and progression of MM, the patient promptly underwent surgical removal of the pituitary adenoma via a transsphenoidal approach. Since there is currently no consensus on therapeutic guidelines and suggested prognosis for MM with acromegaly, long-term follow-up of such cases is needed.

    Multiple myeloma is the second most common hematological cancer. Although it accounts for only a relatively small percentage of all cancer types, the costs associated with managing multiple myeloma are considerable. Available studies are mainly focused on health care costs. The Costo del Mieloma Multiplo (Cost of MM, CoMiM) study investigated the cost of illness of multiple myeloma in Italy during one year of disease management. CoMiM is a retrospective, prevalence-based, multi-center, cross-sectional study based on a stratified sample of patients seen during normal clinical practice (asymptomatic; symptomatic on drugs; symptomatic receiving autologous stem cell transplantation; plateau/remission). Demographics, clinical history, health care and non-health care resource consumption data were collected. Costs were evaluated from the societal viewpoint and expressed in Euro 2008. Data on 236 patients were analyzed (39 asymptomatic, 17%; 29 symptomatic receiving autologous stem-cell transplantation, 12%; 105 symptomatic receiving drugs, 44%; 63 plateau/remission, 27%). The total cost of illness reached € 19,267.1 ± 25,078.6 (asymptomatic, € 959.3 ± 1091.6; symptomatic receiving drugs, € 21,707.8 ± 21,785.3; symptomatic receiving autologous stem-cell transplantation, € 59,243.7 ± 24,214.0; plateau/remission, € 8130.7 ± 15,092.5). The main cost drivers of total cost of illness were drugs and hospital admissions (46.1% and 29.4%, respectively). Antineoplastics and immunomodulators drove the cost of drugs (21.6% and 21.1% of the total cost of illness). Cost of antineoplastics was led by bortezomib (97.4%), whereas the cost driver for immunomodulators was lenalidomide (99.4%). Cost of hospitalization funded by the Italian National Health Service was strongly influenced by transplantation (94.6%), whereas chemotherapy and skeletal fractures did not exceed 1% and 2%, respectively. Despite some limitations, the CoMiM study provides Italian health care decision

    Smoldering multiple myeloma (SMM) is a biologically heterogeneous, clinically defined entity with a variable rate of progression to symptomatic multiple myeloma (MM). Reliable markers for progression are critical for the development of potential therapeutic interventions. We retrospectively evaluated the predictive value of the evolving pattern of serum M-protein among other progression risk factors in 206 patients with SMM diagnosed between 1973 and 2012. Median time from recognition of evolving type to progression into symptomatic MM was 1.1 years (95% CI 0.5-2.0) and progression rate at 3 years was 71%. Development of the evolving type drastically worsened the prognostic estimation made at diagnosis for every covariate predictive of progression (serum M-protein size, bone marrow plasma cell infiltration, immunoparesis and Mayo Clinic risk). On average, the hazard ratio for progression to symptomatic MM increased to 5.1 (95% CI 3.4-7.6) after recognition of the evolving type. In conclusion, in patients with SMM the evolving pattern accurately predicts the risk of early progression to symptomatic disease, thereby allowing the identification of ultra-high risk patients who would be candidates for immediate therapy.

    The study was undertaken to determine differences in the expression of cell surface antigens in normal plasma cells and mature myeloma cells. The subjects were 20 patients with multiple myeloma, including 5 A-bomb survivors. Seven normal persons, four with chronic tonsillitis, one with idiopathic thrombocytopenic purpura, and two with chronic lymphadenitis served as controls. In the group of myeloma cells, 12 showed mature myeloma cells of VLA-4[sup +]/VLA-5[sup +]/MPC-1[sup +], and the other 8 showed precursor myeloma cells of VLA-4[sup +]/VLA-5[sup -]/MPC-1[sup -]. In terms of CD56 and CD19, CD56[sup +]/CD19[sup -] were seen in 13 patients, CD56[sup -]/CD19[sup -] in 5, and CD56[sup +]/CD19[sup +] in 2; none of the patients showed phenotype of CD56[sup -]/CD19[sup +]. In the control group, all showed VLA-4[sup +]/VLA-5[sup +]/MPC-1[sup +]/CD44[sup +]/CD56[sup -]/CD19[sup +]; phenotype of normal plasma cells was CD38[sup ++]/CD56[sup -]/CD19[sup +] alone, which was not seen in the group of mature myeloma cells. Thus, this type is considered characteristic to normal plasma cells. These findings revealed that the difference in the expression of CD56 and CD19 aids in the identification of myeloma cells from normal plasma cells. (N.K.).

    Full Text Available Raphael E Steiner, Elisabet E Manasanch Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Carfilzomib is a proteasome inhibitor that binds selectively and irreversibly to the 20S proteasome, the proteolytic core particle within the 26S proteasome, resulting in the accumulation of proteasome substrates and ultimately growth arrest and apoptosis of tumor cells. The development and ultimate approval of this medication by regulatory agencies has been an important step toward improving clinical outcomes in multiple myeloma. Although initially approved as a single agent for the treatment of multiply relapsed and/or refractory myeloma, in the USA, it is now widely used in the early relapse setting in combination with lenalidomide and dexamethasone. Carfilzomib has also been studied in combination with second-generation immunomodulatory drugs, histone deacetylase inhibitors, alkylating agents and other novel medications. In this review article, we will discuss the efficacy, safety, tolerability and quality of life of carfilzomib-based combination therapies, as well as novel agents, for relapsed multiple myeloma.

  18. Smoldering multiple myeloma: pathophysiologic insights, novel diagnostics, clinical risk models, and treatment strategies.

    Science.gov (United States)

    Kazandjian, Dickran; Mailankody, Sham; Korde, Neha; Landgren, Ola

    2014-09-01

    Smoldering multiple myeloma (SMM) is a plasma cell disorder first described in 1980 when 6 patients were observed to meet the diagnostic criteria of multiple myeloma, defined as bone marrow plasmacytosis of 10% or greater or M protein level of 3 g/dL or greater, but did not have end-organ damage. Subsequent studies showed that the cumulative risk of SMM progression to symptomatic myeloma in 15 years was 73%. Since this time, advances have been made in understanding the biology of progression; namely, the contribution of branching evolution and microenvironment models to clonal heterogeneity. In parallel to this, clinical risk models using standard platforms of serum, bone marrow, and fluorescence in situ hybridization markers along with newer technologies of flow cytometry, gene expression profiling, and magnetic resonance imaging have been developed for prognostic stratification. Treatment has extended to the early myeloma category owing to more sensitive diagnostic approaches. The development of novel treatments will have to take into consideration our current knowledge of biological transformation. While it may be attractive to initiate early treatment in light of recent studies for high-risk SMM patients, clinical trial evidence of efficacy vs toxicity is still in its infancy. In our opinion, high-risk SMM patients should be strongly encouraged to enroll in treatment clinical trials, but treatment with unapproved agents or indications is not supported outside of trials.

    2002-01-01

    Multiple myeloma (MM) is a hematologic malignancy characterized by accumulation of plasma cells in the bone marrow (BM). Bone destruction is a complication of the disease and is usually associated with severe morbidity. The balance between receptor activator of nuclear factor-kappaB (NF......-kappaB) ligand and osteoprotegerin (OPG) is of major importance in bone homeostasis. We have recently shown that serum OPG levels are lower in patients with myeloma than in healthy individuals. Here we show that myeloma cells can bind, internalize, and degrade OPG, thereby providing a possible explanation...... for the lower levels of OPG in the BM of patients with MM. This process is dependent on interaction of OPG with heparan sulfates on the myeloma cells. The results suggest a novel biologic mechanism for the bone disease associated with MM and that treatment of the bone disease with OPG lacking the heparin...

    Immunoglobulin D multiple myeloma is a rare type of multiple myeloma that usually presents as bone pain, fatigue, or weight loss. We report a case of immunoglobulin D multiple myeloma in a 53-year-old Caucasian male patient with previous medical history of anaplastic oligodendroglioma status post-surgical resection who was evaluated for back pain while mowing the lawn. His physical examination showed tenderness over the lower thoracic vertebrae with no sensory or motor impairment. Initial lab investigations showed normocytic anemia and hypercalcemia with low parathyroid hormone. Magnetic resonance imaging of thoracic spine with and without contrast showed acute pathological fracture of the T12 vertebral body with enhancing soft tissue which extended into the left ventral epidural space and left T11-T12 neural foramen. Serum protein electrophoresis showed abnormal protein band in the gamma globulin. Free light chain assay showed serum free kappa which was elevated at 3,090.0 mg/L (reference range 3.3-19.4 mg/L). Immunoglobulin D was elevated at 566.0 mg/dL (reference range immunoglobulin D multiple myeloma urge clinicians to offer their patients new treatment options especially as of the earlier presentation of this subtype of multiple myeloma and the previous reports of worse prognosis.

Including this case report, 12 cases of patients with both sarcoidosis and multiple myeloma have been reported in the literature. The skeletal lesions of both conditions have many clinical and radiological similarities, and unless clinicians are aware of the association and the possibility of dual pathologies, the diagnosis of multiple myeloma in patients known with sarcoidosis may be missed. We present a case of a patient known with longstanding sarcoidosis who was found to have multiple lesions on magnetic resonance imaging (MRI involving the pelvis and both proximal femurs. Histological analysis revealed the presence of both non-necrotising granulomas consistent with sarcoidosis, and sheets of plasma cells consistent with a plasma cell neoplasm.

    Smoldering myeloma is a heterogeneous clinical entity where a subset of patients has an indolent course of disease that mimics monoclonal gammopathy of undermined significance, whereas others have a more aggressive course that has been described as “early myeloma.” It is defined as either serum M-protein ≥3 g/L or ≥10% monoclonal plasma cells in the bone marrow. There are currently no molecular factors to differentiate risks of progression for these patients. Current recommendations of therap...

    Multiple myeloma still remains a fatal disease. However, in the last months new biological and clinical informations have been provided about this disease. In particular, the immunophenotype of myeloma cells seems indicate, in some patients, a clonal involvement of a stem cell in the pathogenesis of mieloma. Moreover, new biological insights concerning the cytokine network, have revealed a probable effect of some cytokines, such as IL6, IL3, IL4. Finally, new insights in the biology of multiple myeloma have been provided by studies of molecular biology and flow cytometry. As for therapy, the best conventional induction treatment still remains to be defined. In the last years, the increased use of alpha Interferon and new therapeutic modalities, such as transplantation procedures in multiple myeloma, open new hopes toward a cure of this disease. Therefore, in the future a better knowledge of the multiple myeloma biology, associated with a wider use of new effective therapeutic approaches will certainly improve the natural course of this disease.

Treatments utilizing alkylating agents, corticosteroids, proteasome inhibitors, and immunomodulatory drugs have resulted in significant survival benefits, however, despite the advances, relapse is inevitable. Decreased depth and duration of response obtained with each successive relapse of disease is typical of the disease course, thereby highlighting a continuing need for new treatment options. With the introduction of monoclonal antibodies for multiple myeloma, new options for treatment in the relapsed setting are on the horizon. Among the new immunologic agents is daratumumab (DARA, a humanized antibody to CD38 with potent multifaceted antitumor activity. Phase I and II clinical trials have demonstrated significant reduction in serum M-protein and bone marrow plasma cell percentage in refractory patients, with an acceptable toxicity profile. Moreover, ex vivo studies have shown that DARA may be particularly useful in combination with currently used anti-myeloma agents. With a recent breakthrough drug designation by the US Food and Drug Administration, DARA shows promise as mono- and combination therapy for the treatment of relapsed/refractory multiple myeloma.Keywords: multiple myeloma, relapsed, refractory, monoclonal antibody, daratumumab, CD38

    Full Text Available Multiple myeloma (MM is a good target disease in which one can apply cellular immunotherapy, which is based on the graft-versus-myeloma effect. This role of immune effector cells provides the framework for the development of immune-based therapeutic options that use antigen-presenting cells (APCs with increased potency, such as dendritic cells (DCs, in MM. Current isolated idiotype (Id, myeloma cell lysates, myeloma dying cells, DC-myeloma hybrids, or DC transfected with tumor-derived RNA has been used for immunotherapy with DCs. Immunological inhibitory cytokines, such as TGF-β, IL-10, IL-6 and VEGF, which are produced from myeloma cells, can modulate antitumor host immune response, including the abrogation of DC function, by constitutive activation of STAT3. Therefore, even the immune responses have been observed in clinical trials, the clinical response was rarely improved following DC vaccinations in MM patients. We are going to discuss how to improve the efficacy of DC vaccination in MM.

    Cerebrovascular events are a common complication among patients with cancer, increasing morbidity and mortality. However, the association between multiple myeloma and cerebrovascular events remains unclear. We therefore investigated multiple myeloma patients' risk factors for stroke to devise a better stroke-prevention strategy. This study includes consecutive patients 20 years and older who were newly diagnosed with symptomatic multiple myeloma at Taipei Veterans General Hospital, a tertiary medical center, between January 1, 2002 and December 31, 2014. The primary outcome was stroke development. Patients with head injuries, brain tumors, brain parenchymal invasions, or antecedent malignancies were excluded. Hazard ratios (HRs) of stroke risk factors for multiple myeloma patients were estimated by Cox proportional regression analysis. Overall, 395 patients with a median age of 70 years were investigated. In the median follow-up period of 18 months, cerebrovascular events occurred in 16 patients, including 10 ischemic strokes and 6 hemorrhagic strokes. The 5-year estimated cumulative incidence rate was 7.45%. In the multivariate analysis, the κ light chain isotype (adjusted HR, 8.37; 95% confidence interval [CI], 1.91-39.8), previous cerebrovascular accidents (adjusted HR, 5.16; 95% CI, 1.48-17.9), and serum creatinine > 2 mg/dL (adjusted HR, 4.21; 95% CI, 1.10-16.0) were identified as independent risk factors for stroke. Subgroup analysis showed that atrial fibrillation (adjusted HR, 8.07) and previous cerebrovascular accident (adjusted HR, 4.89) are significant risk factors for ischemic stroke. Serum creatinine > 2 mg/dL (adjusted HR, 30.6) and previous cerebrovascular accident (adjusted HR, 13.9) are significant for hemorrhagic stroke. Moreover, therapeutic strategies for multiple myeloma were not associated with stroke in our study. This study demonstrates that risk of stroke increases in myeloma patients with a κ light chain isotype, previous

    Multiple myeloma is typically a disease found in older women and is a rare diagnosis in pregnancy. A 22-year-old woman, gravida 1 para 0, at 32 3/7 weeks of gestation presented with nausea, vomiting, and rib and back pain. She was hypertensive, anemic, thrombocytopenic, and in acute renal insufficiency, with hypercalcemia and laboratory parameters indicative of pancreatitis. She was admitted to the obstetric intensive care unit with working diagnoses of preeclampsia, pancreatitis, nephrolithiasis, and renal insufficiency. She ultimately was delivered because of declining clinical status, and multiple myeloma eventually was diagnosed as the underlying cause of her myriad of problems. Multiple myeloma is unusual during pregnancy. However, in patients with significant and unexplained hypercalcemia, malignancy should remain high on the differential diagnosis.

    Full Text Available Lichen myxoedematosus (LM, a form of primary cutaneous mucinosis, may present either as localized less severe form called papular mucinosis or diffuse more severe form called scleromyxoedema. The diffuse form is almost always associated with monoclonal gammopathy, whereas localized form is not. We report an atypical case of localized form of LM associated with multiple myeloma in a 66-year-old male, who presented with asymptomatic waxy papular eruption on extremities, which on histopathological examination confirmed the diagnosis of cutaneous mucinosis. After initially being put on steroids and hydroxychloroquine with minimal improvement, patient subsequently presented with encephalopathy and on evaluation revealed hypernatremia, hypercalcemia, hypergammaglobulinemia, reversal of albumin-globulin (A/G ratio, azotemia, and lytic lesions in skull X-ray. Bone marrow aspiration and biopsy confirmed multiple myeloma. Patient was successfully treated with standard treatment regimen for multiple myeloma with bortezumib and dexamethasone and his skin lesions subsided completely.

    Multiple myeloma (MM) is characterized by multiple chromosomal aberrations. To assess the contribution of DNA repair to this phenotype, ionizing radiation was used to induce DNA double strand breaks in three MM cell lines. Clonogenic survival assays showed U266 (SF4 = 15.3 + 6.4%) and RPMI 8226 (SF4 = 12.6.0 + 1.7%) were radiation sensitive while OPM2 was resistant (SF4 = 78.9 + 4.1%). Addition of the DNA-PK inhibitor NU7026 showed the expected suppression in radiation survival in OPM2 but increased survival in both radiation sensitive cell lines. To examine non-homologous end joining (NHEJ) repair in these lines, the ability of protein extracts to support in vitro DNA repair was measured. Among the three MM cell lines analyzed, RPMI 8226 demonstrated impaired blunt ended DNA ligation using a ligation-mediated PCR technique. In a bacterial based functional assay to rejoin a DNA break within the {beta}-galactosidase gene, RPMI 8226 demonstrated a 4-fold reduction in rejoining fidelity compared to U266, with OPM2 showing an intermediate capacity. Ionizing radiation induced a robust {gamma}-H2AX response in OPM2 but only a modest increase in each radiation sensitive cell line perhaps related to the high level of {gamma}-H2AX in freshly plated cells. Examination of {gamma}-H2AX foci in RPMI 8226 cells confirmed data from Western blots where a significant number of foci were present in freshly plated untreated cells which diminished over 24 h of culture. Based on the clonogenic survival and functional repair assays, all three cell lines exhibited corrupt NHEJ repair. We conclude that suppression of aberrant NHEJ function using the DNA-PK inhibitor NU7026 may facilitate access of DNA ends to an intact homologous recombination repair pathway, paradoxically increasing survival after irradiation. These data provide insight into the deregulation of DNA repair at the site of DNA breaks in MM that may underpin the characteristic genomic instability of this disease.

    Full Text Available Corticosteroids and melphalan were used for decades to treat multiple myeloma. Combination chemotherapy has been extensively studied with similar overall survival rates to melphalan and prednisone. In the last decade, the development of new agents has progressed significantly. Thalidomide and its newer derivatives lenalidomide, bortezomib, and pegylated liposomal doxorubicin have drastically revolutionized treatment approaches. As a result, numerous clinical trials have yielded exciting treatment strategies resulting in therapeutic advances, and improved responses and overall survival of patients. This review summarizes the international uniform response criteria for multiple myeloma and gives a historical perspective on previous therapies with updates on the newest available treatments.

    2015-01-01

    Smoldering multiple myeloma (SMM) is a precursor disease of multiple myeloma (MM) with an average annual risk of progression to MM of 10%. Several prognostic factors have been identified and combined in models to discriminate patient groups with different outcomes. These factors include size of the M-protein, plasma cell (PC) infiltration in the bone marrow (BM), serum free light-chain ratio, immunoparesis and percentage of aberrant BMPCs on flow cytometry or the presence of focal lesions on magnetic resonance imaging. The current standard of care has been to initiate treatment with progression to symptomatic MM. Current approaches aim at identifying patients with an ultra-high risk of progression (≥ 80% within the first 2 years) who are considered as 'early myeloma' patients requiring therapy. A recent trial on high-risk SMM patients, comparing early treatment with lenalidomide plus dexamethasone (Rd) versus observation, reported a benefit with respect to time to progression and survival for Rd-treated patients. Therefore, in 2014, the International Myeloma Working Group (IMWG) revised the diagnostic criteria and proposed to treat patients with ultra-high risk SMM as symptomatic MM. Promising markers for further studies may be high levels of circulating and high proliferative rate of PCs, abnormal PC phenotype with > 95% plus immunoparesis, evolving SMM, specific cytogenetic subtypes, genomic and additional biomarkers; all being acknowledged by the IMWG be added to the diagnostic criteria in the future, if any proves to be associated with a risk of progression of SMM to MM of at least 80% within 2 years.

    Full Text Available The simultaneous presentation of the Hodgkin lymphoma and multiple myeloma in the absence of prior chemotherapy or radiation is very rare. Here, we discuss a 72-year-old patient who initially presented with generalized pruritis. Workup led to a diagnosis of multiple myeloma which progressed and required treatment. As part of his pretreatment workup, an MRI was performed to evaluate skeletal lesions. This revealed diffuse and bulky adenopathy which was confirmed by PET. A biopsy of an axillary node was consistent with the nodular sclerosing type Hodgkin lymphoma. He was treated with adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD chemotherapy × 6 resulting in complete resolution of his adenopathy and pruritis as well as improvement in his myeloma.

    With growing numbers of elderly multiple myeloma patients, reliable tools to assess their vulnerability are required. The objective of the analysis herein was to develop and validate an easy to use myeloma risk score (revised Myeloma Comorbidity Index) that allows for risk prediction of overall survival and progression-free survival differences in a large patient cohort. We conducted a comprehensive comorbidity, frailty and disability evaluation in 801 consecutive myeloma patients, including comorbidity risks obtained at diagnosis. The cohort was examined within a training and validation set. Multivariate analysis determined renal, lung and Karnofsky Performance Status impairment, frailty and age as significant risks for overall survival. These were combined in a weighted revised Myeloma Comorbidity Index, allowing for the identification of fit (revised Myeloma Comorbidity Index ≤3 [n=247, 30.8%]), intermediate-fit (revised Myeloma Comorbidity Index 4-6 [n=446, 55.7%]) and frail patients (revised Myeloma Comorbidity Index >6 [n=108, 13.5%]): these subgroups, confirmed via validation analysis, showed median overall survival rates of 10.1, 4.4 and 1.2 years, respectively. The revised Myeloma Comorbidity Index was compared to other commonly used comorbidity indices (Charlson Comorbidity Index, Hematopoietic Cell Transplantation-Specific Comorbidity Index, Kaplan-Feinstein Index): if each were divided in risk groups based on 25% and 75% quartiles, highest hazard ratios, best prediction and Brier scores were achieved with the revised Myeloma Comorbidity Index. The advantages of the revised Myeloma Comorbidity Index include its accurate assessment of patients' physical conditions and simple clinical applicability. We propose the revised Myeloma Comorbidity Index to be tested with the "reference" International Myeloma Working Group frailty score in multicenter analyses and future clinical trials. The study was registered at the German Clinical Trials Register (DRKS

    Full Text Available Literature on concurrent association of sarcoidosis with lymphoproliferative malignancies other than lymphoma e.g. multiple myeloma is meager. The rarity of the situation prompted us to report this patient who was a 51-year-old woman with a 2-years history of breathlessness, cough with expectoration, chest pain and backache. Initial evaluation revealed mild anemia, increased alkaline phosphatase with chest skiagram showing both lower zone non homogenous opacities with calcified hilar lymph nodes. CECT chest showed mediastinal with bilateral hilar lymphadenopathy, parenchymal fibrosis, traction bronchiectasis, ground glass opacities, septal and peribronchovascular thickening affecting mid and lower lung zones bilaterally. MRI Dorsolumbar spine was suggestive of marrow infiltrative disorder. EBUS FNA of intrathoracic nodes, EBB and TBLB confirmed sarcoidosis. PET CT revealed hyper metabolic activity in lung, multiple lymph nodes and lytic bone lesions. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin IgG kappa type. Bone marrow biopsy revealed an increase in plasma cells (15%, but no granulomas. Diagnosis of Indolent or multiple myeloma with sarcoidosis was established. 12 cases of sarcoidosis and multiple myeloma have been reported in literature, and mostly preceding the onset of multiple myeloma by many years, in our case both were diagnosed concurrently.

    2012-01-01

    Insulin-like growth factor-1 (IGF-1), insulin, and IL-6 are dysregulated in multiple myeloma pathogenesis and may also contribute to multiple myeloma etiology. To examine their etiologic role, we prospectively analyzed concentrations of serologic markers in 493 multiple myeloma cases and 978 controls from 8 cohorts in the Multiple Myeloma Cohort Consortium. We computed odds ratios (ORs) and 95% confidence intervals (CIs) for multiple myeloma per 1-SD increase in biomarker concentration using conditional logistic regression. We examined heterogeneity by time since blood collection (≤ 3, 4- ≤ 6, and > 6 years) in stratified models. Fasting IGF binding protein-1 concentration was associated with multiple myeloma risk within 3 years (OR, 95% CI per 1-SD increase: 2.3, 1.4-3.8, P = .001) and soluble IL-6 receptor level was associated within 6 years after blood draw (OR ≤ 3 years, 95% CI, 1.4, 1.1-1.9, P = .01; OR4- ≤ 6 years, 95% CI, 1.4, 1.1-1.7, P = .002). No biomarker was associated with longer-term multiple myeloma risk (ie, > 6 years). Interactions with time were statistically significant (IGF binding protein-1, P-heterogeneity = .0016; sIL6R, P-heterogeneity = .016). The time-restricted associations probably reflect the bioactivity of tumor and microenvironment cells in transformation from monoclonal gammopathy of undetermined significance or smoldering multiple myeloma to clinically manifest multiple myeloma.

    Background: Multiple myeloma risk increases with higher adult body mass index (BMI). Emerging evidence also supports an association of young adult BMI with multiple myeloma. We undertook a pooled analysis of eight case-control studies to further evaluate anthropometric multiple myeloma risk factors, including young adult BMI. Methods: We conducted multivariable logistic regression analysis of usual adult anthropometric measures of 2,318 multiple myeloma cases and 9,609 controls, and of young adult BMI (age 25 or 30 years) for 1,164 cases and 3,629 controls. Results: In the pooled sample, multiple myeloma risk was positively associated with usual adult BMI; risk increased 9% per 5-kg/m 2 increase in BMI [OR, 1.09; 95% confidence interval (CI), 1.04-1.14; P = 0.007]. We observed significant heterogeneity by study design ( P = 0.04), noting the BMI-multiple myeloma association only for population-based studies ( P trend = 0.0003). Young adult BMI was also positively associated with multiple myeloma (per 5-kg/m 2 ; OR, 1.2; 95% CI, 1.1-1.3; P = 0.0002). Furthermore, we observed strong evidence of interaction between younger and usual adult BMI ( P interaction adult BMI may increase multiple myeloma risk and suggest that healthy BMI maintenance throughout life may confer an added benefit of multiple myeloma prevention.

    Abstract Background Multiple myeloma (MM) is a plasma cell malignancy with a multifaceted immune dysfunction. Indoleamine 2,3-dioxygenase 1 (IDO1) degrades tryptophan into kynurenine (KYN), which inhibits effector T cells and promote regulatory T-cell (Treg) differentiation. It is presently unknown whether MM cells express IDO1 and whether IDO1 activity correlates with immune system impairment. Methods We investigated IDO1 expression in 25 consecutive patients with symptomatic MM and in 7 pat...

    It is recommended that patients with multiple myeloma should be assessed for unmet holistic needs at key times in their disease trajectory. The aim of this exploratory study was to characterise the holistic needs of advanced, intensively treated multiple myeloma using a structured assessment tool. Patients with multiple myeloma who had undergone a haematopoietic stem cell transplantation and subsequent treatment for at least one episode of progressive disease but were in stable plateau phase were included in the study. Patients' holistic needs were assessed using the self-reporting tool, Sheffield Profile for Assessment and Referral for Care (SPARC). Thirty-two patients with a median age of 60 years at assessment and a median of 5.5 years from diagnosis were recruited. Using the SPARC, half of the patients reported tiredness as 'quite a bit/very much,' while one third complained that daytime somnolence and insomnia were 'quite a bit/very much.' Forty-four percent of patients reported pain. One third of patients were bothered and distressed by the side effects from their treatment and were worried about long-term effects of their treatment. Thirty-one percent of patients felt that the effect of their condition had an impact on their sexual life, and 40 % were worried about the effect that their illness was having on their family or other people. This is the first study to use a self-reported holistic needs assessment tool in multiple myeloma. A multidimensional structured questionnaire like the SPARC could provide a useful first step in the effective delivery of supportive and palliative care for patients with multiple myeloma.

    Multiple myeloma (MM) is caused by the neoplastic proliferation of plasma cells. These neoplastic plasma cells proliferate and produce monoclonal immunoglobulin in the bone marrow causing skeletal damage, a hallmark of multiple myeloma. Other MM-related complications include hypercalcemia, renal insufficiency, anemia, and infections. The NCCN Multiple Myeloma Panel members have developed guidelines for the management of patients with various plasma cell dyscrasias, including solitary plasmacytoma, smoldering myeloma, multiple myeloma, systemic light chain amyloidosis, and Waldenström's macroglobulinemia. The recommendations specific to the diagnosis and treatment of patients with newly diagnosed MM are discussed in this article. Copyright © 2017 by the National Comprehensive Cancer Network.

    Multiple myeloma is an incurable disease requiring the development of effective therapies which can be used clinically. We have elucidated the potential for manipulating the cAMP signaling pathway as a target for inhibiting the growth of multiple myeloma cells. As a model system, we primarily used the murine multiple myeloma cell line MOPC315 which can be grown both in vivo and in vitro. Human multiple myeloma cell lines U266, INA-6 and the B-cell precursor acute lymphoblastic leukemia cell line Reh were used only for in vitro studies. Cell death was assessed by flow cytometry and western blot analysis after treatment with cAMP elevating agents (forskolin, prostaglandin E2 and rolipram) and cAMP analogs. We followed tumor growth in vivo after forskolin treatment by imaging DsRed-labelled MOPC315 cells transplanted subcutaneously in BALB/c nude mice. In contrast to the effect on Reh cells, 50 μM forskolin more than tripled the death of MOPC315 cells after 24 h in vitro. Forskolin induced cell death to a similar extent in the human myeloma cell lines U266 and INA-6. cAMP-mediated cell death had all the typical hallmarks of apoptosis, including changes in the mitochondrial membrane potential and cleavage of caspase 3, caspase 9 and PARP. Forskolin also inhibited the growth of multiple myeloma cells in a mouse model in vivo. Elevation of intracellular levels of cAMP kills multiple myeloma cells in vitro and inhibits development of multiple myeloma in vivo. This strongly suggests that compounds activating the cAMP signaling pathway may be useful in the field of multiple myeloma

    Asymptomatic (smoldering) multiple myeloma is a heterogeneous plasma cell proliferative disorder with a variable rate of progression to active multiple myeloma or related disorders. Hypercalcemia, renal insufficiency, anemia, bone lesions or recurrent bacterial infections characterize active multiple myeloma. Some patients with asymptomatic myeloma develop active disease rapidly, and others can stay asymptomatic for many years. Those who are likely to progress within the first 2 years of diagnosis have been categorized as having high-risk disease. The availability of novel agents in the treatment of active multiple myeloma and our better understanding of the heterogeneity of asymptomatic multiple myeloma have spurred interest in the early treatment of these patients. We have reviewed the current proposed definitions of high-risk asymptomatic multiple myeloma, the concerns about future therapy in view of the transient nature, remissions and toxicities of the therapies, and the eventual relapses that characterize this incurable disease.

    The US Food and Drug Administration (FDA) approved 10 new drugs for the treatment of multiple myeloma (MM) over the last two decades. The influx of new anti-myeloma agents with high efficacy and acceptable tolerability add complexity to the clinical decision-making process. First, treatment of smoldering multiple myeloma (SMM) remains investigational to date, although a randomized trial showed a survival gain in high-risk patients receiving lenalidomide. Second, in newly diagnosed MM, the majority of contemporary induction regimens have been studied in single-arm trials or compared to an older regimen, which complicates evidence-based treatment selection. Third, the role of consolidation chemotherapy followed by autologous stem cell transplant (ASCT) needs to be revisited in the context of highly effective agents, as newer regimens- such as carfilzomib, lenalidomide, and dexamethasone-are able to achieve extremely deep responses equivalent to or exceeding those seen after conventional induction and ASCT. Fourth, risks and benefits of maintenance therapy should also be redefined and individualized, as long-term survival and safety data accumulate. Here we selected four clinical settings where controversies exist, reviewed evidences behind conflicting treatment strategies, and asked myeloma experts to discuss evidence-based recommendations.

  5. MGUS and Smoldering Multiple Myeloma: Diagnosis and Epidemiology.

    Science.gov (United States)

    Mateos, María-Victoria; Landgren, Ola

    Monoclonal gammopathy of undetermined significance (MHUS) is characterized by the presence of a serum M-protein less than 3 g/dL, less than 10 % clonal plasma cells in the bone marrow, and the absence of myeloma-defining event. Smoldering multiple myeloma (SMM) is an asymptomatic disorder characterized by the presence of ≥3 g/dL serum M-protein and/or 10-60 % bone marrow plasma cell infiltration with no myeloma-defining event. The risk of progression to multiple myeloma (MM) requiring therapy varies greatly for individual patients, but it is uniform and 1 % per year for MGUS, while higher (10 % per year) and not uniform for SMM patients. The definition of MM was recently revisited patients previously labeled as SMM with a very high risk of progression (80-90 % at 2 years) were included in the updated definition of MM requiring therapy. The standard of care is observation for MGUS patients and although this also applies for SMM, a recent randomized trial targeting high-risk SMM showed that early intervention was associated with better progression-free and overall survival. Biomarkers have become an integrated part of diagnostic criteria for MM requiring therapy, as well as clinical risk stratification of patients with SMM. This paper reviews and discusses clinical implications for MGUS and SMM patients.

In the wake of this rapid approval arose a large number of questions about its mechanism of action and toxicity as well as its ultimate role in the treatment of this disease. In this article, we briefly review the preclinical and clinical development of the drug as the underpinning for a systematic review of the large number of clinical trials that are beginning to shed some light on the full therapeutic potential of bortezomib in myeloma. We conclude with our current understanding of the mechanism of action of this agent and a discussion of the novel proteasome inhibitors under development, as it will be progress in these areas that will ultimately determine the true potential of proteasome inhibition in myeloma.Keywords: bortezomib, multiple myeloma

    After decades of virtually no progress, multiple myeloma survival has improved significantly in the past 10 years. Indeed, multiple myeloma has perhaps seen more remarkable progress in treatment and patient outcomes than any other cancer during the last decade. Recent data show that multiple myeloma is consistently preceded by a precursor state (monoclonal gammopathy of undetermined significance [MGUS]/smoldering multiple myeloma [SMM]). This observation provides a framework for prospective studies focusing on transformation from precursor disease to multiple myeloma and for the development of treatment strategies targeting "early myeloma." This review discusses current biological insights in MGUS/SMM, provides an update on clinical management, and discusses how the integration of novel biological markers, molecular imaging, and clinical monitoring of MGUS/SMM could facilitate the development of early treatment strategies for high-risk SMM (early myeloma) patients in the future.

    The prognosis of patients with multiple myeloma has significantly improved after the introduction of novel concepts of immunomodulation and proteasome inhibition in myeloma therapies. In conjunction with the use of high-dose therapy and autologous stem cell transplantation, these newer antimyeloma agents facilitated the augmentation of deeper responses and as a result, enhanced survival outcomes. Despite mounting clinical evidence that novel therapies may mitigate the poor prognostic impact of some predictors historically considered "harbingers of doom" in myeloma such as t(4;14), the benefit of these advances is less evident in patients who present with genetically defined high-risk features such as presence of chromosomal abnormalities del17p, t(14;16), or t(14;20), or among patients presenting with plasma cell leukemia. With better understanding of the biology of the disease and further recognition of the genomic instability of the high-risk clonal plasma cell influencing both inherent and acquired therapeutic resistance, newer targeted treatment strategies will hopefully improve prognosis in future among this subset of patients with poorer outcomes. In this review, we not only focus on how to identify the genetically defined high-risk patients with myeloma but also describe the most optimal antimyeloma combination strategies that so far have shown to demonstrate long-term benefits for these patients.

    Full Text Available Multiple myeloma, being a malignant proliferation of plasma cells in the bone marrow, has clinical spectrum varying from monoclonal gammopathy with unknown significance to plasma cell leukemia. The presenting symptoms have usually been bone pain, pathologic fractures or repeating infections. In patients with multiple myeloma, amyloid depositions may be seen in the skin. This form, defined as primary systemic amyloidosis, is characterized by light-chain amyloid fibril depositions. Our case applied with multiple, asymptomatic, yellowish papules localized on the face, trunk, oral and genital mucosa, gradually increasing during the last two years. He had no complaints, except for slight weight loss. In routine tests, the patient had no pathological laboratory findings, except high C-reactive protein levels. Further research revealed histopathologic and immunohistochemical findings consistent with amyloidosis. Upon these results, immunoglobulin G levels were measured and found high, and in protein electrophoresis, IgG monoclonal gammopathy was determined. The diagnosis of multiple myeloma is made by bone marrow biopsy. This patient is presented for being an asymptomatic case diagnosed by skin findings of amyloidosis.

    Auto-immun events are rare in multiple myeloma (MM). Here, we report one MM case complicated by Evans syndrome (Autoimmun hemolytic anemia (AIHA) associated with thrombocytopenia). A 52-year-old man was admitted in nephrology department with severe anemia, renal insufficiency and hypergamma globulinemia. Laboratory exams showed acute hemolysis due to an IgG warm autoantibody. Serum electrophoresis revealed the presence of a monoclonal IgG protein and urinary M protein was 2g/day. A whole body CT-Scan showed osteolytic lesions of vertebral body of C5, D4, L3, L4 and the left iliac wing. The diagnosis of multiple myeloma and Evan's syndrome was made, we underwent chemotherapy by BTD (bortezomib-thalidomide-dexamethasone) and continuous corticosteroid therapy but unfortunately the patient died secondary of a Lactic acidosis. The relationship between MM and hemolysis remain unclear. PMID:28292089

    2006-01-01

    The hyponatremia found in multiple myeloma and which is associated with a reduced anion gap (ag) is considered to be pseudohyponatremia due to the displacement of water by the high globulin content in the blood. Serum proteins participate in acid-base balance. Stewart and other authors in their approach to acid-base interpretation acknowledge electrical neutrality as a fundamental characteristic of body fluids. Furthermore, they have shown that both the strong ion difference (SID) and protein, specifically, negatively-charged albumin affect hydrogen ion concentration (H(+)) in the body--i.e., for example an increase in SID leads to a decrease in H(+) and a decrease in albumin leads to a similar effect. The M proteins of multiple myeloma are positively charged. As a result they cause a decrease in sodium levels and the anion gap and thus a true hyponatremia.

Erythropoiesis-stimulating agents (ESA have been used for renal anemia since 1986, and considerably later in cancer anemia. The first studies were published around 1993, but the use of ESA did not become common in cancer anemia until in the late 1990s. Cancer anemia is still under-treated. This review gives an overview of the use of ESA in hematologic malignancies. A background is given about this treatment in the cancer field generally. The pathophysiology of cancer anemia is described with special emphasis on the disturbances in iron metabolism. Functional iron deficiency has been shown to be both frequent and important as a hindrance for response to ESA treatment, and recent studies are reported in some detail, where the use of intravenous iron was shown to improve the response rate of ESA treatment.Keywords: Epo, epoetin, ESA, cancer anemia, lymphoma, myeloma, lymphoproliferative disease

    A study of 75 myeloma patients diagnosed at the Kenyatta National Hospital, Nairobi, is presented. The male to female ratio was 1.7:1; the mean age +/- s.d. was 51.5 +/- 12.5 (range 16-80) years; the peak age incidence of 32% occurred in the sixth decade. A combination of: anaemia (81.3%), osteolytic lesions on X-ray skeletal survey (80%), bone pains (66.7%) and an ESR above 50mm/hr (77.3%) formed an important diagnostic tetrad. Other significant findings included: hypoalbuminaemia (76%), elevated leukocyte alkaline phosphatase (61.3%), uraemia (54.7%), upper respiratory tract infections (44%), elevated serum creatinine (34.7%), raised alkaline phosphatase (33.3%), pathological fractures (32%), hyperuricaemia (30.7%) and hypercalcaemia (29.3). The study confirms that the disease is not infrequent in indigenous Kenyan Africans as previous literature seemed to suggest. Poor prognosis was significantly (p less than 0.05) associated with hypoalbuminaemia, raised serum blood urea, hyperuricaemia and an elevated serum creatinine level.

    Smoldering multiple myeloma (SMM) bridges the gap between monoclonal gammopathy of undetermined significance (a mostly premalignant disorder) and active multiple myeloma (MM). Until recently, no interventional study in patients with SMM showed improved overall survival (OS) with therapy as compared with observation. A report from the PETHEMA-GEM (Programa Español de Tratamientos en Hematologica) group described both fewer myeloma-related events and better OS among patients with high-risk SMM who were treated with lenalidomide and dexamethasone. This unique study prompted us to review current knowledge about SMM and address the following questions: (1) Are there patients currently defined as SMM who should be treated routinely? (2) Should the definitions of SMM and MM be reconsidered? (3) Has the time come when not treating is more dangerous than treating? (4) Could unintended medical harm result from overzealous intervention? Our conclusion is that those patients with the highest-risk SMM (extreme bone marrow plasmacytosis, extremely abnormal serum immunoglobulin free light chain ratio, and multiple bone lesions detected only by modern imaging) should be reclassified as active MM so that they can receive MM-appropriate therapy and the paradigm of careful observation for patients with SMM can be preserved.

    The purpose of this study was to assess the efficacy of cementoplasty in the treatment of sacral multiple myelomas. We retrospectively reviewed the records of eight patients (four women and four men; age range 47-68 years; mean age 57.8) who underwent cementoplasty for painful osteolytic localization of multiple myeloma between April 2007 and May 2009. The patients had difficulty walking because of increasing pain. Six patients had persistent pain despite other cementoplasties for vertebral and femoral localization, whereas two patients referred at the time of diagnosis had only sacral lesions. The clinical indication for treatment was (1) a pain intensity score ≥5 on visual analogue scale (VAS) and (2) pain totally or partially refractory to analgesic treatment in patients with a life expectancy >3 months. Technical planning was based on computed tomography and/or magnetic resonance imaging. Six patients had previously undergone radiotherapy or chemotherapy and were receiving varying doses of analgesics, whereas sacroplasty represented the first treatment for two patients. Five patients had monolateral local involvement, and the other patients had massive involvement of the sacrum; Technical success was achieved in all cases. We had only one small and asymptomatic foraminal leak. All patients experienced improvement in symptoms after the procedure, as demonstrated by improved VAS scores and performance status (PS) and decreased analgesic dose constant during follow-up. In our experience, percutaneous stabilization can be used effectively and safely in patients with focal or extensive involvement of the sacrum by multiple myeloma.

    The authors assess the role of Computed Topography in the diagnosis and management of multiple myeloma (MM) and investigate if Computed Tomography findings can influence the clinical approach, prognosis and treatment. 273 multiple myeloma patients submitted to Computed Tomography June 1994, to December, 1996. The patients were 143 men and 130 women (mean age: 65 years): 143 were stage I, 38 stage II and 92 stage III according to Durie and Salomon's clinical classification. All patients were submitted to blood tests, spinal radiography and Computed Tomography, the latter with serial 5-mm scans on several vertebral bodies. Computed Tomography despicted vertebral arch and process involvement in 3 cases with the vertebral pedicle sign. Moreover, Computed Tomography proved superior to radiography in showing the spread of myelomatous masses into the soft tissues in a case with solitary permeative lesion in the left public bone, which facilitated subsequent biopsy. As for extraosseous localizations, Computed Tomography demonstrated thoracic soft tissue (1 woman) and pelvic (1 man) involvement by myelomtous masses penetrating into surrounding tissues. In our series, only a case of osteosclerotic bone myeloma was observed in the pelvis, associated with lytic abnormalities. Computed Tomography findings do not seem to improve the clinical approach and therapeutic management of the disease. Nevertheless, the authors reccommend Computed Tomography for some myelomatous conditions, namely: a) in the patients with focal bone pain but normal skeletal radiographs; b) in the patients with M protein, bone marrow plasmocytosis and back pain, but with an incoclusive multiple myeloma diagnosis; c) to asses bone spread in the regions which are anatomically complex or difficult to study with radiography and to depict soft tissue involvement; d) for bone biopsy

    To compare the Anion gap between patients of multiple myeloma and normal individuals presenting at a tertiary care hospital. This is a matched case-control study conducted at Aga Khan University Hospital, Karachi, from July 10, 2004 to April 30, 2006. The anion gap (AG) from the medical records of the 82 diagnosed cases of multiple myeloma (MM) and 104 controls were compared. Immunoglobulins (IgG and IgA) were measured by array nephelometric assay. Staging for MM patients were performed based on Salmon-Durie method. AGs were compared by independent sample t-test. Pearson coefficient of correlation was used to correlate paraprotein IgG concentration and anion gap. : Of the 186 study subjects (82 cases and 104 controls), 70% were males and 30% were females. The mean ages of MM and controls were 59.68+/-11.94 and 60+/-9.2 years respectively. There was a significant difference in mean AG, 11.2+/-1.7 mmol/L in control group (panion gap of 8.7+/-1.7 in stage I, 7.93+/-0.47 in stage II and 5.65+/-0.31 in stage III. A significant correlation was found in IgG myeloma when anion gap was expressed as a function of the serum monoclonal protein concentration. The anion gap is significantly lower in multiple myeloma patients compared to controls. Lowered anion gap is more specific feature of the IgG type MM. We suggest that correlation of AG with the disease severity and with paraproteins concentration could potentially be useful in monitoring patients for disease progression. However, longitudinal studies are required to confirm the utility of anion gap in monitoring patients with MM.

    Multiple myeloma is a hematologic disorder characterized by the infiltration and proliferation of monoclonal plasma cells mainly in the bone marrow. The main symptoms are hypercalcemia, renal impairment, cytopenia/anemia and bone disease - summarized as CRAB-criteria. Symptomatic multiple myeloma is consistently preceded by asymptomatic premalignant stages called monoclonal gammopathy of undetermined significance and smoldering multiple myeloma. Staging of multiple myeloma is based on the measurement of the monoclonal protein in serum and urine as well as the assessment of impairment of hematopoiesis, renal function and mineralized bone. In the last decade the development of novel therapeutic agents has led to an increase in response rates and survival time of patients with multiple myeloma, which further stresses the value of response assessment by imaging. Cross sectional imaging like MRI and CT is currently replacing conventional radiological surveys in the initial work-up and follow-up of patients with monoclonal plasma cell diseases. The added value of MRI is to improve initial staging by unraveling a diffuse infiltration of bone marrow by plasma cells, a focal pattern or a combination of both. Furthermore, a complete remission of myeloma confirmed by MRI and CT goes along with a better prognosis compared to a complete response based only on serological parameters.

    Smoldering multiple myeloma (SMM) is an asymptomatic disorder characterized by the presence of at least 3 g/dL of serum M-protein and/or 10% to 60% bone marrow plasma cell infiltration with no myeloma-defining event. The risk of progression to active multiple myeloma (MM) is not uniform and several markers are useful for identifying patients at high risk of progression. The definition of the disease has recently been revisited and patients with asymptomatic MM at 80% to 90% of progression risk at 2 years are now considered to have MM. Although the current standard of care is not to treat, a randomized trial in patients with high-risk SMM that compared early treatment versus observation demonstrated that early intervention resulted in substantial benefits in terms of time to progression and overall survival (OS). These findings highlight the need to follow a correct diagnosis by an accurate risk stratification to plan an optimized follow-up according to the risk of disease progression.

    Smoldering multiple myeloma (SMM) is an asymptomatic plasma cell disorder characterized by the presence of ≥ 3 g/dL serum M-protein and/or 10% to 60% bone marrow plasma cell infiltration with no myeloma-defining event. The risk of progression to active multiple myeloma (MM) is not uniform, and several markers are useful for identifying patients at high risk of progression. The definition of the disease has recently been revisited and asymptomatic MMs at 80% to 90% of progression risk at 2 years are now considered to be active MM candidates for treatment. In the future, more precise biomarkers are necessary for accurate risk stratification to plan an optimized follow-up according to the risk of progression, as well as to expand the group of patients that can obtain a benefit if they receive early treatment. A phase 3, randomized trial in high-risk patients with SMM comparing early treatment versus observation has shown a significant benefit in terms of time to progression and overall survival for early intervention and confirmatory clinical trials will definitively contribute to establish the early treatment as standard of care in high-risk SMM.

    Full Text Available Myeloma bone disease (MBD is a devastating complication of multiple myeloma (MM. More than 80% of MM patients suffer from destructive bony lesions, leading to pain, fractures, mobility issues, and neurological deficits. MBD is not only a main cause of disability and morbidity in MM patients but also increases the cost of management. Bone destruction and lack of bone formation are main factors in the development of MBD. Some novel factors are found to be involved in the pathogenesis of MBD, eg, receptor activator of nuclear factor kappa-B ligand (RANKL, osteoprotegerin (OPG system (RANKL/OPG, Wingless (Wnt, dickkopf-1 (Wnt/DKK1 pathway. The addition of novel agents in the treatment of MM, use of bisphosphonates and other supportive modalities such as radiotherapy, vertebroplasty/kyphoplasty, and surgical interventions, all have significant roles in the treatment of MBD. This review provides an overview on the pathophysiology and management of MBD.

    Robust and reliable imaging methods are required to estimate the skeletal tumor load in multiple myeloma, as well as for the diagnosis of extraskeletal manifestations. Imaging also plays an essential role in the assessment of fracture risk and of vertebral fractures. The conventional skeletal survey has been the gold standard in the imaging of multiple myeloma for many years. Other modalities which have been investigated and are in use are whole-body computed tomography (WBCT), 18F-fluorodeoxyglucose positron emission tomography computed tomography (FDG PET-CT) and whole-body magnetic resonance imaging (WBMRI). These techniques are able to depict both mineralized bone and the bone marrow with a high sensitivity for myeloma lesions. Several studies have shown that cross-sectional imaging is superior to the skeletal survey in the detection of myeloma lesions and WBMRI has been shown to be significantly more sensitive than WBCT for the detection of focal myeloma lesions as well as for diffuse infiltration. The FDG PET-CT technique has a sensitivity comparable to WBMRI. Due to the higher sensitivity in the detection of myeloma lesions WBCT and WBMRI should replace the skeletal survey. A WBCT should be performed if there is suspicion of multiple myeloma. If no focal lesions are found WBMRI or at least MRI of the spine and pelvis should be additionally performed if available. If WBMRI has been initially performed and focal lesions are present, an additional WBCT may be performed to assess the extent of bone destruction and fracture risk. In cases of monoclonal gammopathy of undetermined significance (MGUS), solitary and smoldering myeloma, a WBMRI, if available, should be performed in addition to WBCT. (orig.)

    Full Text Available Abstract Background Plasma cell neoplasms represent autonomous proliferations of plasma cells and can manifest as diffuse myeloma with systemic involvement (plasma cell myeloma or multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS, or as variants of plasma cell myeloma such as indolent myeloma, smoldering myeloma, osteosclerotic myeloma, plasma cell leukaemia and non-secretory myeloma. Localized neoplastic proliferation of plasma cells presents as solitary plasmacytoma of bone or extramedullary plasmacytoma. Involvement of orbit can occur as a solitary plasmacytoma, or as part of systemic involvement in multiple myeloma, the clinical outcome being significantly worse in the latter setting. Orbital involvement in multiple myeloma is very rare with less than 50 cases reported in the literature. Early cytological diagnosis of such lesions is vital for timely institution of appropriate therapy. As far as we are aware only six previous cases of cytological diagnosis of multiple myeloma involving the orbit are on record. Case presentation A 37 year old male presented with low grade fever showing evening rise, headache, diplopia and swelling in the right periorbital and temporal region. Imaging studies revealed destructive lesion of sphenoid, frontal bone and zygomatic arch with soft tissue component extending to infratemporal fossa and orbit. A fine needle aspirate from the temporal region swelling showed features of a plasmacytoma, and subsequent workup confirmed the presence of systemic disease. A final diagnosis of multiple myeloma with orbital involvement at presentation was made. Conclusion Present case describes the extremely rare presentation of multiple myeloma with orbital involvement and highlights the utility of cytology in such lesions. Fine needle aspiration diagnosis of plasmacytoma at extramedullary sites offers an opportunity for non-invasive verification of systemic involvement, and thus plays a major role in

    Monoclonal gammopathy of undetermined significance (MGUS) is one of the most common premalignant disorders. IgG and IgA MGUS are precursor conditions of multiple myeloma (MM), whereas light-chain MGUS is a precursor condition of light-chain MM. Smoldering MM (SMM) is a precursor condition with higher tumor burden and higher risk of progression to symptomatic MM compared to MGUS. Assessment of the risk of progression of patients with asymptomatic monoclonal gammopathies is based on various factors including clonal burden, as well as biological characteristics, such as cytogenetic abnormalities and light-chain production. Several models have been constructed that are useful in daily practice for predicting risk of progression of MGUS or SMM. Importantly, the plasma cell clone may occasionally be responsible for severe organ damage through the production of a M-protein which deposits in tissues or has autoantibody activity. These disorders are rare and often require therapy directed at eradication of the underlying clone. Importantly, recent studies have shown that asymptomatic patients with a bone marrow plasma cell percentage ≥60%, free light-chain ratio ≥100, or >1 focal lesion on MRI (myeloma-defining events) have a 80% risk of developing symptomatic MM within 2 years. These patients are now considered to have MM requiring therapy, similar to patients with symptomatic disease. In this review, we provide an overview of the new diagnostic criteria of the monoclonal gammopathies and discuss risk of progression to active MM. We also provide recommendations for the management of patients with MGUS and SMM including risk-adapted follow-up. © 2016 John Wiley & Sons Ltd.

    Multiple myeloma is a common hematological malignancy. Aggressive myeloma invades the organs outside the bone marrow, lymph, or reticuloendothelial systems. Among the extramedullary involvements of multiple myeloma, myelomatous ascites are extremely rare and are associated with a poor prognosis. We describe a case of myelomatous ascites as an initial manifestation of extramedullary involvement of multiple myeloma in 39-year-old patient. The patient was treated with high-dose chemotherapy, but extensive extramedullary involvement progressed, and the patient expired approximately five months after the initial detection of ascites.

    A markedly elevated serum free light chain (FLC) ratio may serve as a biomarker for malignant transformation in high-risk smoldering multiple myeloma (SMM) and identify patients who are at imminent risk of progression. We retrospectively studied the predictive value of the serum (FLC) assay in 586 patients with SMM diagnosed between 1970 to 2010. A serum involved/uninvolved FLC ratio ≥ 100 was used to define high-risk SMM, which included 15% (n=90) of the total cohort. Receiver operating characteristics analysis determined the optimal FLC ratio cut-point to predict progression to symptomatic multiple myeloma (MM) within 2 years of diagnosis, which resulted in a specificity of 97% and sensitivity of 16%. Fifty-six percent of patients developed progressive disease during median follow-up of 52 months, but this increased to 98% in the subgroup of patients with FLC ratio ≥ 100. The median time to progression in the FLC ratio ≥ 100 group was 15 months versus 55 months in the FLC <100 group (P<0.0001). The risk of progression to MM within the first 2 years in patients with an FLC ratio ≥ 100 was 72%; the risk of progression to MM or light chain amyloidosis in 2 years was 79%. We conclude that a high FLC ratio ≥ 100 is a predictor of imminent progression in SMM, and such patients may be considered candidates for early treatment intervention.

    The purpose of this pictorial essay is to increase awareness of the clinical presentation, neuroradiological findings, treatment options, and neuroradiological follow-up of plasmacytomas and multiple myeloma with intracranial growth. This pictorial essay reviews the clinical features and neuroradiological findings in seven patients (four women, three men; age range at diagnosis 62-82 years) followed in two institutions. Six patients, one with IgG-{kappa} plasmacytoma, and five with IgG-{kappa}(n=3), IgG-{lambda}(n=1), and nonsecretory (n=1) multiple myeloma, had been seen over a period of 9 years in one institution, and the other patient with IgG-{kappa} plasmacytoma had been seen over a period of 3.5 years in the other. Intracranial involvement is rare, most frequently resulting from osseous lesions in the cranial vault, skull base, nose, or paranasal sinuses. Primary dural or leptomeningeal involvement is rarer. Some typical findings of a dural and/or osseous plasmacytoma include iso- to hyperdensity on CT scan, T1 equal to high signal intensity and T2 markedly hypointense signal on MRI, and high vascularity possibly documented on intraarterial digital subtraction angiography. However, the neuroradiological findings generally lack specificity, since they are generally no different from those of meningioma, metastasis, lymphoma, dural sarcoma, plasma cell granuloma, infectious meningitis, and leptomeningeal carcinomatosis. The spectrum of clinical and neuroradiological evaluation shows that intracranial involvement from plasmacytoma and multiple myeloma must be taken into account in the differential diagnosis of cranial osseous and meningeal disease.

    2008-09-01

    Because of the development of novel agents such as immunomodulators, proteasome inhibitors, and bisphosphonates, the standards of care for the multiple myeloma (MM) patient have changed. The costs associated with current and emerging therapies, as well as supportive care, are significant and pose a tremendous financial burden to both patients and managed care. To review the economic impact of MM and to weigh the advantages and disadvantages of current treatments in bringing value for prolonged life versus the cost of treatment. This chapter will also discuss the need for thorough data review and pharmacoeconomic analyses to determine the most cost-effective therapies. Although MM accounts for only a small percentage of all cancer types, the costs associated with treating and managing it are among the highest. Recent developments in diagnosing, treating, and managing myeloma have led to novel treatment strategies. Immunomodulators, proteasome inhibitors, and bisphosphonates are improving response rates and preserving quality of life. However, these agents are not replacing older treatment modalities, but being used in addition to them. Intensive chemotherapy, stem cell transplantation, and supportive care are all important components in achieving treatment goals. Costs associated with stem cell transplants and complications of the disease add to the economic burden of myeloma. Additional costs for routine diagnostics to measure the progression of the disease or response to treatment need to be considered. Complications (e.g., lytic bone disease, infection, anemia, and renal failure) also add to morbidity and mortality, thus increasing the burden to the patient and the health care system as a whole. Financial and time constraints of caregivers must also be considered, as well as the added administrative burdens to health care providers. New standards of care in the treatment and management of myeloma are likely to lead to significant increases in costs. Although

    Progress in the treatment of multiple myeloma in the last decade has been able to delay, but ultimately not to prevent, the development of resistances and most patients still die of the disease or its related complications. New drugs have been developed including new alkylating agents, proteasome inhibitors and immunomodulators but also monoclonal antibodies and drugs with new mechanisms of action. Hopefully, this new generation of targeted agents will improve the results of the initial therapy, avoid relapses and development of resistances and provide better and less toxic options for the relapsed and refractory patient.

    Full Text Available Purulent pericarditis caused by Morganella morganii is extremely rare. We report herein a case of a 61-year-old man who presented with chest pain and dyspnea fourteen days after chemotherapy for multiple myeloma. Echocardiogram and computed tomography revealed a massive pericardial effusion and associated cardiac tamponade. Pericardiocentesis was performed. Pericardial fluid was found to be purulent, and Morganella morganii was isolated from the fluid. The patient was successfully treated with antibiotic therapy and surgical drainage of the fluid. Morganella morganii should be considered a possible pathogen when immunocompromised patients develop purulent pericarditis.

    Multiple myeloma is a plasma cell malignancy characterized by monoclonal gammopathy and osteolytic bone lesions. Multiple myeloma is most commonly diagnosed in late disease stages, presenting with pathologic fracture. Early diagnosis and monitoring of disease status may improve quality of life and long-term survival for multiple myeloma patients from what is now a devastating and fatal disease. We have developed a near-infrared targeted fluorescent molecular probe with high affinity to the α4β1 integrin receptor (VLA-4)overexpressed by a majority of multiple myeloma cells as a non-radioactive analog to PET/CT tracer currently being developed for human diagnostics. A near-infrared dye that emits about 700 nm was conjugated to a high affinity peptidomimmetic. Binding affinity and specificity for multiple myeloma cells was investigated in vitro by tissue staining and flow cytometry. After demonstration of sensitivity and specificity, preclinical optical imaging studies were performed to evaluate tumor specificity in murine subcutaneous and metastatic multiple myeloma models. The VLA-4-targeted molecular probe showed high affinity for subcutaneous MM tumor xenografts. Importantly, tumor cells specific accumulation in the bone marrow of metastatic multiple myeloma correlated with GFP signal from transfected cells. Ex vivo flow cytometry of tumor tissue and bone marrow further corroborated in vivo imaging data, demonstrating the specificity of the novel agent and potential for quantitative imaging of multiple myeloma burden in these models.

    Renal impairment is a common complication of patients with multiple myeloma (MM). We aimed to evaluate the clinical significance of 2 newly discovered biomarkers of renal injury, cystatin C (CysC), a protein reflecting glomerular filtration rate, and neutrophil gelatinase-associated lipocalin (NGAL), a protein reflecting tubular injuries. We studied 64 patients with newly diagnosed myeloma: 16 with asymptomatic (smoldering) MM and 48 with symptomatic myeloma; 8 patients with monoclonal gammopathy of undetermined significance (MGUS); and 20 healthy control subjects. Along with common blood and urine chemistry determinations, measurements of CysC, NGAL, β2-microglobulin, high-sensitivity C-reactive protein, and interleukin 6 were performed. We found that only patients with symptomatic MM had increased levels of CysC compared to controls (P 50.5 μg/L have a 80.8% sensitivity and 86.4% specificity for eGFR < 60 mL/min (area under the curve = 0.764). These findings suggest that both NGAL and CysC are very sensitive markers that reflect renal impairment in newly diagnosed patients with MM. The high levels of NGAL in asymptomatic patients and in MGUS patients support the hypothesis of the presence of renal damage in these patients early in the course of their disease and may reveal NGAL to be an early marker that predicts the presence of renal impairment in MM.

    Full Text Available Anemia é uma complicação comum em pacientes com mieloma múltiplo (MM e ocorre em mais de 2/3 dos pacientes. Anemia de doença crônica, deficiência de eritropoetina (EPO devido à insuficiência renal e efeito mielossupressivo da quimioterapia são os principais mecanismos patofisiológicos que contribuem para o desenvolvimento de anemia no MM. Nos pacientes que obtêm remissão completa com tratamento quimioterápico, anemia usualmente se normaliza. Nos pacientes que não respondem ou apresentam recaída do mieloma, anemia freqüentemente persiste. As opções de tratamento dos pacientes anêmicos com MM incluem transfusões de hemácias e EPO recombinante humana. Essa proteína é biologicamente equivalente à EPO endógena e sua administração promove aumento dos valores de hemoglobina por tempo mais prolongado sem os riscos das transfusões de sangue. Vários estudos têm relatado melhora significante da eritropoese, redução da necessidade transfusional e melhora da qualidade de vida com o uso da EPO como tratamento a longo prazo da anemia associada ao mieloma. Nesse artigo, propomos o tratamento da anemia do MM baseado nas recomendações propostas pela Sociedade Americana de Hematologia (ASH em conjunto com a Sociedade Americana de Oncologia Clínica (ASCO, pela Organização Européia para Pesquisa e Tratamento do Câncer (EORTC, pelo IMF (Internacional Myeloma Foundation e pelo NCCN (National Comprehensive Cancer Network.Anemia is a common complication in patients with multiple myeloma (MM occurring in more than two thirds of all patients. Anemia of chronic diseases, erythropoietin (EPO deficiency due to renal impairment and the myelosuppressive effect of chemotherapy are the most important pathophysiological mechanisms contributing to the development of anemia in MM. In patients who achieve complete remission after chemotherapy, anemia usually normalizes. Non-responders and relapsing myeloma patients often continue to suffer

    IgM multiple myeloma (MM) and Waldenstrom's macroglobulinemia (WM) are two distinct hematologic entities with the common finding of an IgM monoclonal gammopathy. Distinguishing these two diagnoses is critical as the approach to therapy is different. A priori, we defined IgM MM as a symptomatic clonal plasma cell proliferative disorder characterized by an IgM monoclonal protein (regardless of size), 10% or more plasma cells on bone marrow biopsy, plus the presence of lytic bone lesions and/or translocation t(11;14). Twenty-one patients met this definition of IgM MM. All 21 patients had lytic bone lesions. Of the 16 evaluated with FISH, 6 (38%) demonstrated t(11;14). Median overall survival was 30 months, which is similar to non-IgM myeloma patients treated during this period and shorter than what would be expected for WM. In this, the largest series of patients with IgM MM, we describe the clinical features and prognosis of patient with IgM MM using a strict definition for the disease. The subset of patients without lytic lesions or t(11;14) but with immunophenotypic features suggestive of MM need further study. © 2010 Wiley-Liss, Inc.

    The science of multiple myeloma (MM) and related plasma cell disorders is rapidly evolving with increased understanding of the disease biology and recent approval of the newer drugs widening the therapeutic armamentarium. Despite multiple international guidelines regarding the management of this disease, the practice of managing MM is not uniform amongst Indian physicians. There are challenges in management which are unique to the Indian patients. This review discusses these challenges and the consensus of the nation-wide experts in dealing with the same. We also briefly highlighted the perspective of international experts as discussed in the Myeloma State of the Art conference held in September 2016 at PGI, Chandigarh. An I ndian M yeloma A cademic G roup e (IMAGe) group was formed to strengthen the research, create awareness about myeloma and related disorders and form consensus guidelines/ recommendations that can be adapted to the Indian Scenario.

    Full Text Available Katja Weisel Department of Hematology/Oncology, University Hospital Tuebingen, Tuebingen, Germany Abstract: Despite advances in the treatment of multiple myeloma, it remains an incurable disease, with relapses and resistances frequently observed. Recently, immunotherapies, in particular, monoclonal antibodies, have become important treatment options in anticancer therapies. Elotuzumab is a humanized monoclonal antibody to signaling lymphocytic activation molecule F7, which is highly expressed on myeloma cells and, to a lower extent, on selected leukocyte subsets such as natural killer cells. By directly activating natural killer cells and by antibody-dependent cell-mediated cytotoxicity, elotuzumab exhibits a dual mechanism of action leading to myeloma cell death with minimal effects on normal tissue. In several nonclinical models of multiple myeloma, elotuzumab was effective as a single agent and in combination with standard myeloma treatments, supporting the use of elotuzumab in patients. In combination with lenalidomide and dexamethasone, elotuzumab showed a significant increase in tumor response rates and progression-free survival in patients with relapsed and/or refractory multiple myeloma. This review summarizes the nonclinical and clinical development of elotuzumab as a single agent and in combination with established therapies for the treatment of multiple myeloma.

    Involvement of the central nervous system (CNS) is a rare complication of multiple myeloma (MM). Herein, we have described the incidence, characteristics, prognostic factors for post CNS-MM survival, and outcome of CNS-MM and explored the efficacy of novel agents (NA) (thalidomide, bortezomib, lenalidomide) in this setting. Between 2000 and 2013, 31 (0.9 %) out of 3408 newly diagnosed symptomatic MM patients, consecutively diagnosed and treated during the same period in 12 Greek centers, developed CNS-MM (M/F 15/16, median age 59 years, range 20-96 years; newly diagnosed/relapsed-refractory 2/29; median time to CNS-MM diagnosis 29 months). Clinical and laboratory characteristics were retrospectively recorded. Twenty-six percent of patients had circulating plasma cells (PCs) or plasma cell leukemia (PCL) at CNS-MM and 39 % had skull-derived plasmacytomas, suggesting hematological and contiguous spread. Treatment for CNS-MM was offered in 29/31 patients and 11/29 responded (NA 18/29, additional radiotherapy 9/28, intrathecal chemotherapy 13/29). The median post CNS-MM survival was 3 months (95 % CI 1.9-4.1) and did not differ between patients treated with NA and/or radiotherapy vs. others. In the multivariate analysis, prior treatment of MM with NA, extramedullary disease (EMD) during MM course (i.e., plasmacytomas, circulating PCs, or documented PCL) and abnormally high LDH at MM diagnosis were independent prognostic factors, whereas treatment of CNS-MM with NA did not predict for post CNS-MM survival. Despite the relatively limited number of patients due to the rarity of CNS-MM, our results suggest that NA do not seem to improve post CNS-MM survival. Patients with EMD display shortened post CNS-MM survival and should be followed thoroughly.

  20. Recent advances in multiple myeloma: a Korean perspective.

    Epidemiologically, multiple myeloma (MM) is a malignant disorder of plasma cells with a higher incidence among Western populations than among Asians. However, there is growing evidence of a recent increase in the age-standardized incidence rate (ASR) of MM in Asian countries, particularly Korea. Application of novel agents has resulted in significant improvement of treatment outcomes, and the advances are ongoing with the recent introduction and U.S. Food and Drug Administration's approval of newer agents, including carfilzomib, ixazomib, elotuzumab, and daratumumab. In concert with the technical advances in the cytogenetic and molecular diagnostics of MM, modifications of its diagnosis and staging system have been attempted for better risk stratification. The modified diagnostic criteria from the International Myeloma Working Group in 2014 enabled a strategy of more active treatment for some patients with smoldering MM, with an ultra-high risk of progression, and fine-tuned the definition of end-organ damage, known as CRAB (hypercalcemia, renal insufficiency, anemia, and bone lesions). Considering Korea's trend of aging at an unprecedented rate, we can expect that the ASR of MM will maintain a gradual increase for many years to come; therefore, MM will be a cancer of critical importance from both medical and socioeconomic perspectives in Korea.

    2016-12-01

    Multiple myeloma (MM), although a rare disease, is the second most common hematologic malignancy. It is found in the spectrum of plasma cell dyscrasias, which begins with monoclonal gammopathy of unknown significance (MGUS) to overt plasma cell leukemia and extramedullary myeloma. MM is associated with significant morbidity due to its end-organ destruction. It is a disease of the older population and its incidence in the African American population is twice that of the European American population. Improvements in the treatment of MM in the past couple of decades, beginning with the use of autologous stem cell transplantation followed by availability of novel treatments such as immunomodulatory drugs (ImIDs) and proteasome inhibitors (PIs) has transformed the natural history of the disease leading to longer survival times. Advancements in the diagnosis, monitoring, and treatment of MM are of the utmost importance as the general population lives longer due to other improvements in health care. The recent introduction of novel therapies has been paralleled by advancements in the monitoring of MM, namely, by the availability exquisitely sensitive techniques in detecting minimal residual disease. As drug development and technology continues to improve, it will be important to design rationale clinical trials enrolling patient populations that represent the overall population, including racial minorities and the elderly, so that trial results can be appropriately extrapolated. Herein, the changing epidemiology, improvements in survival, and the health disparity observed in important subgroups of MM are reviewed. Published by Elsevier Inc.

    The role of endothelial progenitor cell (EPC)-mediated vasculogenesis in hematological malignancies is not well explored. Here, we showed that EPCs are mobilized from the bone marrow (BM) to the peripheral blood at early stages of multiple myeloma (MM); and recruited to MM cell-colonized BM niches. Using EPC-defective ID1+/- ID3-/- mice, we found that MM tumor progression is dependent on EPC trafficking. By performing RNA-sequencing studies, we confirmed that endothelial cells can enhance proliferation and favor cell-cycle progression only in MM clones that are smoldering-like and have dependency on endothelial cells for tumor growth. We further confirmed that angiogenic dependency occurs early and not late during tumor progression in MM. By using a VEGFR2 antibody with anti-vasculogenic activity, we demonstrated that early targeting of EPCs delays tumor progression, while using the same agent at late stages of tumor progression is ineffective. Thus, although there is significant angiogenesis in myeloma, the dependency of the tumor cells on EPCs and vasculogenesis may actually precede this step. Manipulating vasculogenesis at an early stage of disease may be examined in clinical trials in patients with smoldering MM, and other hematological malignancies with precursor conditions.

  11. The symptomatic management of multiple sclerosis

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available The management of multiple sclerosis (MS revolves around disease management, symptom management, and person management. Of these, symptom management takes up the bulk of the time of the practicing physician. Some symptoms are easily managed whereas others are more difficult. Decisions have often to be made on whether to treat or to wait and watch. This article discusses the varied symptoms of MS and the approaches to management, which involves rehabilitation, pharmacological treatments, and surgical procedures. The skilled physician managing MS should be familiar with the multiple approaches to improving the quality of life of those with MS. After the diagnosis has been established and the decisions regarding treatment approaches have been made, the talk in a typical office appointment for MS usually turns to symptom management. Thus, the majority of management decisions made by the clinician revolve around that important topic. It is symptom management that will determine quality of life for those with MS, It is the basis for improving function, and, up until twenty years ago, it was the only basis for treating MS. Now, however, we can approach treatment by disease management, symptom management, and person management. The MS specialist must be well versed in all three areas.

    Full Text Available Abstract Indatuximab ravtansine is a monoclonal antibody-linked cytotoxic agent that specifically targets CD138-expressing cells. Monotherapy has been shown to significantly inhibit multiple myeloma tumour growth in vivo and improve host survival. Here, we show that in most cell lines tested, indatuximab ravtansine acts additively or even synergistically with clinically approved therapies for treatment of multiple myeloma. In addition, in vivo mouse xenograft models confirmed the activity of indatuximab ravtansine in combination with lenalidamide and lenalidomide/dexamethasone. Indatuximab ravtansine may therefore be a suitable combination partner for multiple myeloma, and a clinical study is ongoing.

    Full Text Available The development of sensitive and non-invasive “liquid biopsies” presents new opportunities for longitudinal monitoring of tumor dissemination and clonal evolution. The number of circulating tumor cells (CTCs is prognostic in multiple myeloma (MM, but there is little information on their genetic features. Here, we have analyzed the genomic landscape of CTCs from 29 MM patients, including eight cases with matched/paired bone marrow (BM tumor cells. Our results show that 100% of clonal mutations in patient BM were detected in CTCs and that 99% of clonal mutations in CTCs were present in BM MM. These include typical driver mutations in MM such as in KRAS, NRAS, or BRAF. These data suggest that BM and CTC samples have similar clonal structures, as discordances between the two were restricted to subclonal mutations. Accordingly, our results pave the way for potentially less invasive mutation screening of MM patients through characterization of CTCs.

    Actinomycosis is a chronic suppurative infection, for which immune suppression is a predisposing factor. In unusual cases, this disease may present as an abdominal wall involvement simulating a soft tissue tumor as seen in the present case. The presented patient had no signs of trauma or surgical approach and the pathology was considered to be a primary abdominal wall actinomycosis. Preoperative diagnosis is difficult due to the nonspecific nature of clinical presentation, radiographic and laboratory findings. Surgery combined with antibiotic treatment is a curative approach for this relatively rare infection. Surgeons must be aware of this disease in order to ensure correct diagnosis and to prevent performing any unnecessary procedures. The present study describes a case of abdominal actinomycosis with multiple myeloma, together with a review of important points related to this disease. PMID:25202429

Hematology and biochemistry showed pancytopenia and hyperglobulinemia, and serum protein electrophoresis revealed a monoclonal band in the β-globulin region. Necropsy demonstrated hemoabdomen, multifocal lytic bone marrow lesions, splenomegaly, and hemorrhagic hepatic nodules, with left medial lobe rupture. There were mutifocal hemorrhages in the subcutis, lung, epicardium, and intestinal mucosa. Histopathology demonstrated plasmacytoid cells infiltrating the bone marrow, liver and spleen, and circulating within blood vessels. On immunohistochemistry, cell infiltrates of the three tissues were positive for λ light chains, bone marrow infiltrates were positive for MUM-1 and bone marrow and spleen infiltrates were positive for CD20. These findings indicate that this animal died of hemoabdomen subsequent to multiple myeloma. This is the first time this disease has been reported in a tiger.

    OBJECTIVES: Many radiologists and clinicians still consider multiple myeloma (MM) and monoclonal gammopathies (MG) a contraindication for using iodine-based contrast media. The ESUR Contrast Media Safety Committee performed a systematic review of the incidence of post-contrast acute kidney injury...... (PC-AKI) in these patients. METHODS: A systematic search in Medline and Scopus databases was performed for renal function deterioration studies in patients with MM or MG following administration of iodine-based contrast media. Data collection and analysis were performed according to the PRISMA......, in which 12 unconfounded cases of PC-AKI were found (1.6 %). The majority of patients had intravenous urography with high osmolality ionic contrast media after preparatory dehydration and purgation. CONCLUSIONS: MM and MG alone are not risk factors for PC-AKI. However, the risk of PC-AKI may become...

    Multiple myeloma (MM) is a neoplasia characterized by the proliferation of plasmacytoid cells, which produce abnormal immunoglobulins. It frequently creates local and systemic complications such as pathologic fractures and renal disease. This article reports the case of a 70-year-old man presenting a pathologic fracture of the right mandibular angle secondary to a plasmocytoma. He had a history of a previous pathologic fracture of the left mandibular angle 13 years before that was treated elsewhere, but no documentation was available. Investigation revealed the disease to be a MM and evolution led to renal failure and death. Differential diagnosis is necessary for this kind of pathologic presentation because MM presents a survival rate of 5.7% in 5 years and mandibular involvement happens in the advanced stage of the disease.

    Full Text Available During the past decade, overall results of treatment of multiple myeloma (MM have been improved and survival curves are now significantly better with respect to those obtained with historical treatment. These improvements are linked to a deeper knowledge of the biology of disease and to the introduction in clinical practice of drugs with different mechanism of action such as proteasome inhibitors and immunomodulatory drugs (IMiDs. However, MM remains in most cases an incurable disease. For patients who relapse after treatment with novel agents, the prognosis is dismal and new drugs and therapeutic strategies are required for continued disease control. In this review, we summarize new insights in salvage therapy for relapsed/refractory MM as emerging from recent clinical trials exploring the activity of bendamustine, new generation proteasome inhibitors, novel IMiDs, monoclonal antibodies, and drugs interfering with growth pathways.

    Full Text Available Multiple myeloma (MM is a B-cell malignancy that is currently felt to be incurable. Despite recently approved novel targeted treatments such as lenalidomide and bortezomib, most MM patients' relapse is emphasizing the need for effective and well-tolerated therapies for this deadly disease. The use of oncolytic viruses has garnered significant interest as cancer therapeutics in recent years, and are currently under intense clinical investigation. Both naturally occurring and engineered DNA and RNA viruses have been investigated preclinically as treatment modalities for several solid and hematological malignancies. Presently, only a genetically modified measles virus is in human clinical trials for MM. The information obtained from this and other future clinical trials will guide clinical application of oncolytic viruses as anticancer agents for MM. This paper provides a timely overview of the history of oncolytic viruses for the treatment of MM and future strategies for the optimization of viral therapy for this disease.

    Several recent studies have highlighted the biological complexity of multiple myeloma (MM) that arises as a result of several disrupted cancer pathways. Apart from the central role of genetic abnormalities, epigenetic aberrations have also been shown to be important players in the development of MM......, and a lot of research during the past decades has focused on the ways DNA methylation, histone modifications and noncoding RNAs contribute to the pathobiology of MM. This has led to, apart from better understanding of the disease biology, the development of epigenetic drugs, such as histone deacetylase...... inhibitors that are already used in clinical trials in MM with promising results. This review will present the role of epigenetic abnormalities in MM and how these can affect specific pathways, and focus on the potential of novel 'epidrugs' as future treatment modalities for MM....

    We studied 351 patients with smoldering multiple myeloma (SMM) in whom the underlying primary molecular cytogenetic subtype could be determined based on cytoplasmic immunoglobulin fluorescent in situ hybridization studies. Hundred and fifty-four patients (43.9%) had trisomies, 127 (36.2%) had immunoglobulin heavy chain (IgH) translocations, 14 (4%) both trisomies and IgH translocations, 53 (15.1%) no abnormalities detected and 3 (0.9%) had monosomy13/del(13q) in the absence of any other abnormality. Among 127 patients with IgH translocations, 57 were t(11;14), 36 t(4;14), 11 musculoaponeurotic fibrosarcoma (MAF) translocations, and 23 other or unknown IgH translocation partner. Time to progression (TTP) to symptomatic multiple myeloma was significantly shorter in patients with the t(4;14) compared with patients with t(11;14), median 28 versus 55 months, respectively, P=0.025. The median TTP was 28 months with t(4;14) (high-risk), 34 months with trisomies alone (intermediate-risk), 55 months with t(11;14), MAF translocations, other/unknown IgH translocations, monosomy13/del(13q) without other abnormalities, and those with both trisomies and IgH translocations (standard-risk), and not reached in patients with no detectable abnormalities (low-risk), P=0.001. There was a trend to shorter TTP with deletion 17p (median TTP, 24 months). Overall survival from diagnosis of SMM was significantly inferior with t(4;14) compared with t(11;14), median 105 versus 147 months, respectively, P=0.036.

    Multiple myeloma is a neoplastic plasma cell disorder that is characterized by clonal proliferation of plasma cells in the bone marrow, monoclonal protein in the blood and/or urine, and associated organ dysfunction and biomarkers. There have been multiple recent advances in the relapsed and refractory setting. Major steps forward include the introduction of proteasome inhibitors (bortezomib and carfilzomib) and immunomodulatory drugs (thalidomide, lenalidomide, and pomalidomide) in various combinations. These drugs have changed the management of multiple myeloma and have extended overall survival in the past decade. Established curative therapy is not yet available for patients diagnosed with multiple myeloma, supporting the development of new treatment targets. Histone deacetylase inhibitors have multiple proposed mechanisms of action in the treatment of multiple myeloma. Both vorinostat and panobinostat have demonstrated some activity against multiple myeloma, and due to the benefits reported with panobinostat, the U.S. Food and Drug Administration has recently approved the drug for the treatment of relapsed and refractory multiple myeloma. In this article, we describe the pharmacology, efficacy, and toxicity profile of vorinostat and panobinostat and their possible place in therapy. PMID:26684557

    Circulating tumor DNA is a promising biomarker to monitor tumor load and genome alterations. We explored the presence of circulating tumor DNA in multiple myeloma patients and its relation to disease activity during long-term follow-up. We used digital droplet polymerase chain reaction analysis to monitor recurrent mutations, mainly in mitogen activated protein kinase pathway genes NRAS , KRAS and BRAF Mutations were identified by next-generation sequencing or polymerase chain reaction analysis of bone marrow plasma cells, and their presence analyzed in 251 archived serum samples obtained from 20 patients during a period of up to 7 years. In 17 of 18 patients, mutations identified in bone marrow during active disease were also found in a time-matched serum sample. The concentration of mutated alleles in serum correlated with the fraction in bone marrow plasma cells (r=0.507, n=34, P <0.002). There was a striking covariation between circulating mutation levels and M protein in ten out of 11 patients with sequential samples. When relapse evaluation by circulating tumor DNA and M protein could be directly compared, the circulating tumor DNA showed relapse earlier in two patients (3 and 9 months), later in one patient (4 months) and in three patients there was no difference. In three patients with transformation to aggressive disease, the concentrations of mutations in serum increased up to 400 times, an increase that was not seen for the M protein. In conclusion, circulating tumor DNA in myeloma is a multi-faceted biomarker reflecting mutated cells, total tumor mass and transformation to a more aggressive disease. Its properties are both similar and complementary to M protein. Copyright© 2017 Ferrata Storti Foundation.

    The treatment of multiple myeloma has undergone significant changes and has resulted in the achievement of molecular remissions, the prolongation of remission duration, and extended survival becoming realistic goals, with a cure being possible in a small but growing number of patients. In addition, nowadays it is possible to categorize patients more precisely into different risk groups, thus allowing the evaluation of therapies in different settings and enabling a better comparison of results across trials. Here, we review the evidence from clinical studies, which forms the basis for our recommendations for the management of patients with myeloma. Treatment approaches depend on “fitness,” with chronological age still being an important discriminator for selecting therapy. In younger, fit patients, a short three drug-based induction treatment followed by autologous stem cell transplantation (ASCT) remains the preferred option. Consolidation and maintenance therapy are attractive strategies not yet approved by the European Medicines Agency, and a decision regarding post-ASCT therapy should only be made after detailed discussion of the pros and cons with the individual patient. Two- and three-drug combinations are recommended for patients not eligible for transplantation. Treatment should be administered for at least nine cycles, although different durations of initial therapy have only rarely been compared so far. Comorbidity and frailty should be thoroughly assessed in elderly patients, and treatment must be adapted to individual needs, carefully selecting appropriate drugs and doses. A substantial number of new drugs and novel drug classes in early clinical development have shown promising activity. Their introduction into clinical practice will most likely further improve treatment results. PMID:25063227

    Purpose Magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) are important imaging techniques in multiple myeloma (MM). We conducted a prospective trial in patients with MM aimed at comparing MRI and PET-CT with respect to the detection of bone lesions at diagnosis and the prognostic value of the techniques. Patients and Methods One hundred thirty-four patients received a combination of lenalidomide, bortezomib, and dexamethasone (RVD) with or without autologous stem-cell transplantation, followed by lenalidomide maintenance. PET-CT and MRI were performed at diagnosis, after three cycles of RVD, and before maintenance therapy. The primary end point was the detection of bone lesions at diagnosis by MRI versus PET-CT. Secondary end points included the prognostic impact of MRI and PET-CT regarding progression-free (PFS) and overall survival (OS). Results At diagnosis, MRI results were positive in 127 of 134 patients (95%), and PET-CT results were positive in 122 of 134 patients (91%; P = .33). Normalization of MRI after three cycles of RVD and before maintenance was not predictive of PFS or OS. PET-CT became normal after three cycles of RVD in 32% of the patients with a positive evaluation at baseline, and PFS was improved in this group (30-month PFS, 78.7% v 56.8%, respectively). PET-CT normalization before maintenance was described in 62% of the patients who were positive at baseline. This was associated with better PFS and OS. Extramedullary disease at diagnosis was an independent prognostic factor for PFS and OS, whereas PET-CT normalization before maintenance was an independent prognostic factor for PFS. Conclusion There is no difference in the detection of bone lesions at diagnosis when comparing PET-CT and MRI. PET-CT is a powerful tool to evaluate the prognosis of de novo myeloma.

    The serum immunoglobulin-free light chain (FLC) assay measures levels of free kappa and lambda immunoglobulin light chains. There are three major indications for the FLC assay in the evaluation and management of multiple myeloma and related plasma cell disorders (PCD). In the context of screening, the serum FLC assay in combination with serum protein electrophoresis (PEL) and immunofixation yields high sensitivity, and negates the need for 24-h urine studies for diagnoses other than light chain amyloidosis (AL). Second, the baseline FLC measurement is of major prognostic value in virtually every PCD. Third, the FLC assay allows for quantitative monitoring of patients with oligosecretory PCD, including AL, oligosecretory myeloma and nearly two-thirds of patients who had previously been deemed to have non-secretory myeloma. In AL patients, serial FLC measurements outperform PEL and immunofixation. In oligosecretory myeloma patients, although not formally validated, serial FLC measurements reduce the need for frequent bone marrow biopsies. In contrast, there are no data to support using FLC assay in place of 24-h urine PEL for monitoring or for serial measurements in PCD with measurable disease by serum or urine PEL. This paper provides consensus guidelines for the use of this important assay, in the diagnosis and management of clonal PCD.

  15. Targeting proliferating cell nuclear antigen and its protein interactions induces apoptosis in multiple myeloma cells.

    Directory of Open Access Journals (Sweden)

    Rebekka Müller

    Full Text Available Multiple myeloma is a hematological cancer that is considered incurable despite advances in treatment strategy during the last decade. Therapies targeting single pathways are unlikely to succeed due to the heterogeneous nature of the malignancy. Proliferating cell nuclear antigen (PCNA is a multifunctional protein essential for DNA replication and repair that is often overexpressed in cancer cells. Many proteins involved in the cellular stress response interact with PCNA through the five amino acid sequence AlkB homologue 2 PCNA-interacting motif (APIM. Thus inhibiting PCNA's protein interactions may be a good strategy to target multiple pathways simultaneously. We initially found that overexpression of peptides containing the APIM sequence increases the sensitivity of cancer cells to contemporary therapeutics. Here we have designed a cell-penetrating APIM-containing peptide, ATX-101, that targets PCNA and show that it has anti-myeloma activity. We found that ATX-101 induced apoptosis in multiple myeloma cell lines and primary cancer cells, while bone marrow stromal cells and primary healthy lymphocytes were much less sensitive. ATX-101-induced apoptosis was caspase-dependent and cell cycle phase-independent. ATX-101 also increased multiple myeloma cells' sensitivity against melphalan, a DNA damaging agent commonly used for treatment of multiple myeloma. In a xenograft mouse model, ATX-101 was well tolerated and increased the anti-tumor activity of melphalan. Therefore, targeting PCNA by ATX-101 may be a novel strategy in multiple myeloma treatment.

    The characteristics of the proliferation of B-cell activating factor (BAFF) and the proliferation-inducing ligand (APRIL) mRNA expression in mononuclear cell in multiple myeloma patients were detected, and the correlation was analyzed between the BAFF and APRIL concentrations in plasma and tumor burden parameters of multiple myeloma. Bone marrow samples from 60 patients with multiple myeloma and 20 healthy persons taken as controls, were collected. Bone marrow mononuclear cells (BMMCs) were harvested, and plasma was extracted. BAFF and APRIL mRNA expression was quantified using real-time fluorescent quantitative PCR in the BMMCs. ELISA was used to detect the characteristics of gene and protein expression of BAFF and APRIL in KM3 cell line. The BAFF and APRIL mRNA expression in initial treatment group, remission group and non-remission group were markedly higher than that in control group (PBAFF concentration in multiple myeloma (P=0.0027). In conclusion, for the gene and protein expression of BAFF and APRIL in patients with multiple myeloma, the initial treatment group and non-remission are higher than control and remission group. The higher the stage was, the more the factors were expressed. Characteristics of expression of BAFF and APRIL may be used as a new index to evaluate the prognosis of multiple myeloma.

    Multiple myeloma is a plasma cell malignancy evolving in the bone marrow and leading to end organ damage such as bone lesions, cytopenias, and kidney failure. This review delineates recent advances in the molecular mechanisms leading to tumor progression in multiple myeloma. Two different aspects enable tumor expansion: cell autonomous through genomic alterations in the tumor clone and noncell autonomous deregulations in the bone marrow tumor microenvironment. These alterations provide the framework for the continuous progression of multiple myeloma from early precursor conditions such as monoclonal gammopathy of undetermined significance and smoldering multiple myeloma to overt multiple myeloma. In this review, we discuss recent findings in the genomic alterations that occur in the tumor clone such as somatic genomic mutations, copy number variation and chromosomal translocation, and delineate noncell autonomous deregulations in which tumor cells take advantage of a permissive microenvironment to further proliferate. The latter compartment includes interaction with bone marrow stromal cells, osteoblasts, osteoclasts, and immune escape. Understanding the mechanisms that lead tumor progression from early stages to overt multiple myeloma could guide to more effective therapies and therefore prevent disease progression.

    2016-11-01

    Although the input of multiparameter flow cytometry (MFC) into the clinical management of multiple myeloma patients has faced some reluctance, continuously growing evidence supports the utility of MFC in this disease. MFC immunophenotyping of bone marrow and peripheral blood plasma cells affords cost-effective assessment of clonality, and provides prognostic information on the risk of progression in smoldering multiple myeloma, and the identification of active multiple myeloma patients with dismal outcome (e.g., high numbers of circulating tumor cells) or long-term survival despite suboptimal responses through the characterization of monoclonal gammopathy of undetermined significance-like phenotypes. Extensive data indicate that minimal residual disease (MRD) monitoring can be used as biomarker to evaluate treatment efficacy and act as surrogate for survival. The time has come to address within clinical trials the exact role of baseline risk factors and MRD monitoring for tailored therapy in multiple myeloma, which implies systematic usage of highly sensitive cost-effective, readily available, and standardized MRD techniques such as MFC. Next-generation MFC should be considered mandatory in the routine evaluation of multiple myeloma patients both at diagnosis and after therapy, and represents an attractive technique to integrate with high-throughput DNA and RNA-seq methods to help in understanding the mechanisms behind dissemination and chemoresistance of multiple myeloma.

    Circulating vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and selectins were prospectively measured in 145 newly-diagnosed patients with symptomatic myeloma (NDMM), 61 patients with asymptomatic/smoldering myeloma (SMM), 47 with monoclonal gammopathy of undetermined significance (MGUS) and 87 multiple myeloma (MM) patients at first relapse who received lenalidomide- or bortezomib-based treatment (RD, n=47; or VD, n=40). Patients with NDMM had increased VCAM-1 and ICAM-1 compared with MGUS and SMM patients. Elevated VCAM-1 correlated with ISS-3 and was independently associated with inferior overall survival (OS) (45 months for patients with VCAM-1 >median vs 75 months, P=0.001). MM patients at first relapse had increased levels of ICAM-1 and L-selectin, even compared with NDMM patients and had increased levels of VCAM-1 compared with MGUS and SMM. Both VD and RD reduced dramatically serum VCAM-1 after four cycles of therapy, but only VD reduced serum ICAM-1, irrespective of response to therapy. The reduction of VCAM-1 was more pronounced after RD than after VD. Our study provides evidence for the prognostic value of VCAM-1 in myeloma patients, suggesting that VCAM-1 could be a suitable target for the development of anti-myeloma therapies. Furthermore, the reduction of VCAM-1 and ICAM-1 by RD and VD supports the inhibitory effect of these drugs on the adhesion of MM cells to stromal cells.

    We present the case of a 42-year-old man with a painful mass lesion in the right shoulder that was detected by contrast-enhanced computed tomography (CT) and {sup 18}F-fluoro-2-deoxyglucose ({sup 18}F-FDG) positron emission tomography (PET)/CT. Excisional biopsy revealed infiltration of plasma cells with anaplastic features, consistent with solitary plasmacytoma (PC). Serum analysis showed elevation of serum free lambda light chain levels (27.78 mg/l), with an abnormally high kappa:lambda ratio (2.33) and high total proteins (10.4 g/dl). Serum protein electrophoresis revealed an M spike in the gamma-globulin region (56.1 %=5.8 g/dl). Subsequently, {sup 18}F-FDG PET/CT revealed another hypermetabolic mass in the right lobe of the liver. CT-guided biopsy of the liver lesion revealed plasma cell myeloma, consistent with multiple myeloma. Multiple myeloma presenting as nodular liver masses is very rare in clinical practice. In a retrospective review of more than 2,000 patients, Talamo et al. reported only nine cases where there was nodular involvement of the liver by multiple myeloma. The organ most commonly involved was the liver, followed by pancreas, stomach, peritoneum with malignant ascites, colon, rectum, duodenum and ileum. Therefore, the literature published thus far has been limited to a few reports and case series. Among these reports, some had demonstrated the PET or PET/CT findings of nodular liver involvement of multiple myeloma. About 10 % of the solitary myelomas appeared as extramedullary PC or solitary PC of bone. In spite of the advances in therapy, the treatment of multiple myeloma is still palliative. However, solitary PC could be cured by resection or radiation therapy. Thus, differentiation between PC and multiple myeloma is essential in making a decision for the appropriate therapeutic regimen. {sup 18}F-FDG PET/CT has the unique ability to detect and characterize malignant lesions in one single examination.

    Full Text Available We report a case of a 54 - year - old female with history of multiple myeloma on remission with botizomib - dexamethasone regien treatment presents with enlargement and coming out of her right eye with pain, swelling, tearing and pain in the backbone. On examination, it was found that she has proptosis, chemosis, and diplopia along with marked diminision of vision. Initial workup and treatment did not yield significant results; eventually she was found to have myelomatous changes in her right orbit on CT scan & magnetic resonance imaging (MRI of orbit and was diagnosed with multiple myeloma of the orbit that resolved some amount with radiation. This case tends to highlight the importance of considering myeloma of the orbit in a multiple myeloma patient who is on remission with chemotherapy

    Survival of myeloma patients has greatly improved with the use of autologous stem cell transplantation and novel agents, such as proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies. Compared to bortezomib- and lenalidomide-based regimens alone, the addition of high-dose melphalan followed by autologous transplantation significantly improves progression-free survival, although an overall survival benefit was not observed in all trials. Moreover, follow up of recent trials is still too short to show any difference in survival. In the light of these findings, novel agent-based induction followed by autologous transplantation is considered the standard upfront treatment for eligible patients (level of evidence: 1A). Post-transplant consolidation and maintenance treatment can further improve patient outcome (1A). The availability of several novel agents has led to the development of multiple combination regimens such as salvage treatment options. In this context, the role of salvage autologous transplantation and allotransplant has not been extensively evaluated. In the case of prolonged remission after upfront autologous transplantation, another autologous transplantation at relapse can be considered (2B). Patients who experience early relapse and/or have high-risk features have a poor prognosis and may be considered as candidates for clinical trials that, in young and fit patients, may also include an allograft in combination with novel agents (2B). Ongoing studies are evaluating the role of novel cellular therapies, such as inclusion of antibody-based triplets and quadruplets, and chimeric antigen receptor-T cells. Despite encouraging preliminary results, longer follow up and larger patient numbers are needed before the clinical use of these novel therapies can be widely recommended.

    We recently confirmed that ciclopirox olamine inhibits Wnt/beta catenin signalling in myeloma. Griseofulvin (GF) has similar chemical features as compared to ciclopirox olamine. In this study the anti-tumor effect of GF was investigated. GF demonstrated a major apoptotic activity in various human and murine myeloma and lymphoma cell lines as well as in human primary cells. In vivo, tumor growth as well as overall survival were significantly reduced in mice treated with GF as compared to untreated mice. In conclusion, our results reveal a significant selective induction of apoptosis by GF and suggest a significant in vivo effect against myeloma. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Two key features of myeloma cells are the deregulation of the cell cycle and the dependency on the expression of the BCL2 family of anti-apoptotic proteins. The cell division cycle 7 (CDC7) is an essential S-phase kinase and emerging CDC7 inhibitors are effective in a variety of preclinical cancer models. These compounds also inhibit CDK9 which is relevant for MCL-1 expression. The activity and mechanism of action of the dual CDC7/CDK9 inhibitor PHA-767491 was assessed in a panel of multiple myeloma cell lines, in primary samples from patients, in the presence of stromal cells and in combination with drugs used in current chemotherapeutic regimens. We report that in all conditions myeloma cells undergo cell death upon PHA-767491 treatment and we report an overall additive effect with melphalan, bortezomib and doxorubicin, thus supporting further assessment of targeting CDC7 and CDK9 in multiple myeloma

    Full Text Available The paper describes two patients (a 50-year woman and a 72-year man in whom the clinical manifestations of ulceronecrotic vasculitis had long preceded before the diagnosis of multiple myeloma was made. In the former, monoclonal cryoglobulinemia type I induced ulcerative lesions with the development of dry toe gangrene and paraproteinemic renal lesion. In the latter, ulceronecrotic vasculitis with the development of dry toe gangrene was a manifestation of monoclonal paraproteinemia without signs of cryoglobulinemia. Both patients were found to have monoclonal blood secretion (РIgGλ и РIgGκ and urine Bence Jones protein (BJλ+BJκ, BJκ in the absence of immunological markers of vasculitis developing in patients with rheumatic diseases. Immunochemical study of serum/urine and, when monoclonal secretion of PIg+BJ is detected, further examination for plasma cell dyscrasia should be performed in all cases of vascular disorders (cold allergy, Raynaud's syndrome, purpura, ulcers of cruses, and gangrene of distal phalanxes of the hands/feet in patients with atypical vasculitis. The timely immunochemical study of blood and urine will make it possible to diagnose plasma cell dyscrasia (different types of myelomic disease, Waldenstrцm macroglobulinemia, primary amyloidosis at the early stage of the disease and to rule out unjustifiably diagnosed vasculitis in patients with atypical vascular lesions.

    This report describes a novel presentation of chloride resistant metabolic alkalosis in a patient with hypercalcemia related to Multiple Myeloma (MM). A 51-year-old male with newly diagnosed MM presented with widespread skeletal involvement, calcium (Ca(+2)) of 18 mg/dL, phosphorous (PO4) of 6 mg/dL, serum bicarbonate (HCO3) of 37 mEq/L, and serum creatinine (Cr) of 2.6 mg/dL Other causes of metabolic alkalosis such as vomiting, diuretics, alkali ingestion, mineralocorticoid excess and hypokalemia were excluded. Hypercalcemia and metabolic alkalosis were only partially corrected after rehydration, calcitonin and steroids. Subsequent treatment with zoledronic acid resulted in resolution of hypercalcemia and correction of metabolic alkalosis.The chloride resistant component of metabolic alkalosis was most likely related to extensive release of Ca(+2), carbonate and phosphate from bone by activated osteoclasts with inhibited osteoblastic activity. The additional reduction in glomerular filtration rate due to MM, contributed to a triad mimicking Calcium-Alkali syndrome.

    2018-02-01

    Full Text Available Multiple myeloma (MM is an incurable disease caused by the malignant proliferation of bone marrow plasma cells, whose pathogenesis remains largely unknown. Although a large fraction of the genome is actively transcribed, most of the transcripts do not serve as templates for proteins and are referred to as non-coding RNAs (ncRNAs, broadly divided into short and long transcripts on the basis of a 200-nucleotide threshold. Short ncRNAs, especially microRNAs, have crucial roles in virtually all types of cancer, including MM, and have gained importance in cancer diagnosis and prognosis, predicting the response to therapy and, notably, as innovative therapeutic targets. Long ncRNAs (lncRNAs are a very heterogeneous group, involved in many physiological cellular and genomic processes as well as in carcinogenesis, cancer metastasis, and invasion. LncRNAs are aberrantly expressed in various types of cancers, including hematological malignancies, showing either oncogenic or tumor suppressive functions. However, the mechanisms of the related disease-causing events are not yet revealed in most cases. Besides emerging as key players in cancer initiation and progression, lncRNAs own many interesting features as biomarkers with diagnostic and prognostic importance and, possibly, for their utility in therapeutic terms as druggable molecules. This review focuses on the role of lncRNAs in the pathogenesis of MM and summarizes the recent literature.

    Systemic mastocytosis (SM) is a disease characterized by a clonal infiltration of mast cells affecting various tissues of the body. It is grouped into six different subtypes according to the World Health Organization classification. It is called indolent systemic mastocytosis (ISM) when there is no evidence of end organ dysfunction, while the presence of end organ dysfunction defines aggressive systemic mastocytosis (ASM). When SM coexists with a clonal hematological disorder, it is classified as systemic mastocytosis with associated clonal hematological nonmast cell lineage disease (SM-AHNMD). Over 80% of SM-AHNMD cases involve disorders of the myeloid cell lines. To our knowledge, there are only 8 reported cases to date of SM associated with a plasma cell disorder. We report a patient with ISM who was found to have concomitant smoldering multiple myeloma. His disease later progressed to ASM. We discuss this rare association between SM and a plasma cell disorder, and potential common pathophysiologic mechanisms linking the two disorders will be reviewed. We also discuss prognostic factors in SM as well as the management options considered during the evolution of the patient's disease.

    Full Text Available The association between Neurofibromatosis type I (NF1 and multiple myeloma (MM, a plasma cell, dyscrasia is very rare. Here we put to the attention of the scientific community two new cases. The first one is a patient with active MM whereas the second with smoldering MM. Both patients present typical features of NF1 but skeletal alterations were present only in the second case including dysplasia, marked scoliosis and osteoporosis. MM osteolytic lesions were absent in both patients. In addition to the clinical diagnosis of NF1, a molecular testing for NF1 gene mutations has been performed finding that patient one was heterozygous for the c.6855C>A (Tyr2285Ter mutation, whilepatient two was heterozygous for thec.7838dupC (Lys2614GlufsTer20 mutation. The two mutations were diagnosed both in genomic DNA from peripheral blood and from MM cells. The potential link between NF1 mutation and the increased risk of MM is discussed in the report.

    2016-06-01

    Carfilzomib, a second-generation proteasome inhibitor, has been increasingly used in relapsed/refractory multiple myeloma (MM) since its approval by the American food and drug administration (FDA) in the summer of 2012. The drug is active as a single agent and in combination with other antimyeloma agents. As a result of its efficacy and safety in the relapsed/refractory setting, carfilzomib is being evaluated in patients with newly diagnosed MM as well as in high-risk smoldering MM. This review will give a comprehensive summary of the drug, including its mechanism of action, the evaluated doses and schedules as well as a summary of the main clinical trials in the relapsed/refractory and newly diagnosed settings. A focus will be placed upon certain subgroups of interest as well as a description of the toxicity associated with carfilzomib use and a clinical perspective on toxicity management. © 2016 John Wiley & Sons A/S.

    The measurement of serum free light chain (sFLC) has been shown to be valuable in screening for the presence of plasma cell dyscrasia as well as for baseline prognosis in newly diagnosed patients. The aim of the present work was to study the prognostic value of sFLC in multiple myeloma in relation to other serum biomarkers, response to therapy and survival. Forty five newly diagnosed patients with MM were included in the study. Patients were divided into responders and non-responders groups according to response to therapy. sFLC and serum Amyloid A (SAA) were measured by immunonephelometry. The non-responders group showed a statistically significant higher kappa/lambda or lambda/kappa ratio and higher β2 microglobulin level, but lower albumin level at presentation, as compared to the responders group (P < 0.001). However, no statistically significant difference was detected between the two groups regarding SA A or calcium levels. Comparison between sFLC ratio obtained before and after therapy revealed significant decrease after treatment in the responders group (P = 0.05). Survival was significantly inferior in patients with an FLC ratio of ≥ 2.6 or ≤ 0.56 compared with those with an FLC ratio that was between 0.56 and 2.6 (P = 0.002).

    A previously healthy 32-year-old Caucasian female presented with sudden-onset horizontal diplopia following a paroxysm of coughing. She had recently sustained a pubic ramus fracture during an innocuous fall and had also noted a firm lump developing at the right side of her forehead. On examination, she had a right fronto-temporal mass. Visual acuities were 6/6 bilaterally. There was reduced abduction of the right eye, bilateral white, granular corneal opacities and evidence of bilateral optic disc swelling. Haematological investigations revealed normocytic anaemia, hypercalcaemia and raised erythrocyte sedimentation rate (ESR). CT showed lytic foci throughout the skull, ribs, scapulae, spine, pelvis and upper femora. Serum protein electrophoresis revealed immunoglobulin D (IgD)-kappa paraproteinaemia; urine electrophoresis showed free light chain kappa and bone marrow biopsy demonstrated 87% plasma cells. A diagnosis of IgD multiple myeloma was made, with subsequent chemotherapeutic treatment and eventual autologous stem cell transplant resulting in resolution of neuro-ophthalmic manifestations and prolonged disease remission.

  17. Multiple Myeloma Macrophages: Pivotal Players in the Tumor Microenvironment

    Directory of Open Access Journals (Sweden)

    Simona Berardi

    2013-01-01

    Full Text Available Tumor microenvironment is essential for multiple myeloma (MM growth, progression, and drug resistance through provision of survival signals and secretion of growth and proangiogenic factors. This paper examines the importance of macrophages within MM bone marrow (BM microenvironment, referred to as MM-associated macrophages, as a potential niche component that supports tumor plasma cells. These macrophages are derived from peripheral blood monocytes recruited into the tumor. Upon activation by MM plasma cells and mesenchymal stromal cells, macrophages can release growth factors, proteolytic enzymes, cytokines, and inflammatory mediators that promote plasma cell growth and survival. Macrophages promote tumor progression through several mechanisms including angiogenesis, growth, and drug resistance. Indeed, these macrophages are essential for the induction of an angiogenic response through vasculogenic mimicry, and this ability proceeds in step with progression of the plasma cell tumors. Data suggest that macrophages play an important role in the biology and survival of patients with MM, and they may be a target for the MM antivascular management.

    Full Text Available Multiple myeloma (MM remains an incurable disease despite recent therapeutic improvements. The ability to detect and characterize MM circulating tumour cells (CTCs in peripheral blood provides an alternative to replace or augment invasive bone marrow (BM biopsies with a simple blood draw, providing real-time, clinically relevant information leading to improved disease manage‐ ment and therapy selection. Here we have developed and qualified an enrichment-free, cell-based immunofluores‐ cence MM CTC assay that utilizes an automated digital pathology algorithm to distinguish MM CTCs from white blood cells (WBCs on the basis of CD138 and CD45 expression levels, as well as a number of morphological parameters. These MM CTCs were further characterized for expression of phospho-ribosomal protein S6 (pS6 as a readout for PI3K/AKT pathway activation. Clinical feasi‐ bility of the assay was established by testing blood samples from a small cohort of patients, where we detected popu‐ lations of both CD138pos and CD138neg MM CTCs. In this study, we developed an immunofluorescent cell-based assay to detect and characterize CTCs in MM.

    High-dose therapy and auto-SCT remain integral in the initial treatment of multiple myeloma (MM), and are increasingly being applied for management of relapsed disease. We examined the outcomes in 98 patients undergoing salvage auto-SCT (auto-SCT2) for relapsed MM after receiving an initial transplant (auto-SCT1) between 1994 and 2009. The median age at auto-SCT2 was 60 years (range: 35-74). The median time between auto-SCT1 and auto-SCT2 was 46 months (range: 10-130). Treatment-related mortality was seen in 4%. The median PFS from auto-SCT2 was 10.3 (95% confidence interval (CI): 7-14) months and the median OS from auto-SCT2 was 33 months (95% CI: 28-51). In a multivariable analysis, shorter time to progression (TTP) after auto-SCT1, not achieving a CR after auto-SCT2, higher number of treatment regimens before auto-SCT2 and a higher plasma cell labeling index at auto-SCT2 predicted for shorter PFS. However, only a shorter TTP after auto-SCT1 predicted for a shorter OS post auto-SCT2. Hence, auto-SCT2 is an effective and feasible therapeutic option for MM patients relapsing after other treatments, especially in patients who had a TTP of at least 12 months after their auto-SCT1.

    Background: Increased expression of the tetraspanin TSPAN7 has been observed in a number of cancers; however, it is unclear how TSPAN7 plays a role in cancer progression. Methods: We investigated the expression of TSPAN7 in the haematological malignancy multiple myleoma (MM) and assessed the consequences of TSPAN7 expression in the adhesion, migration and growth of MM plasma cells (PC) in vitro and in bone marrow (BM) homing and tumour growth in vivo. Finally, we characterised the association of TSPAN7 with cell surface partner molecules in vitro. Results: TSPAN7 was found to be highly expressed at the RNA and protein level in CD138{sup +} MM PC from approximately 50% of MM patients. TSPAN7 overexpression in the murine myeloma cell line 5TGM1 significantly reduced tumour burden in 5TGM1/KaLwRij mice 4 weeks after intravenous adminstration of 5TGM1 cells. While TSPAN7 overexpression did not affect cell proliferation in vitro, TSPAN7 increased 5TGM1 cell adhesion to BM stromal cells and transendothelial migration. In addition, TSPAN7 was found to associate with the molecular chaperone calnexin on the cell surface. Conclusion: These results suggest that elevated TSPAN7 may be associated with better outcomes for up to 50% of MM patients. - Highlights: • TSPAN7 expression is upregulated in newly-diagnosed patients with active multiple myeloma. • Overexpression of TSPAN7 inhibits myeloma tumour development in vivo. • TSPAN7 interacts with calnexin at the plasma membrane in a myeloma cell line.

    2016-10-01

    Elotuzumab is a humanized monoclonal antibody targeting the extracellular domain of signaling lymphocytic activation molecule F7 (SLAMF7) highly expressed in multiple myeloma cells. Upon binding to myeloma cells, elotuzumab exerts its cytotoxic effects through antibody-dependent cellular cytotoxicity, the antibody-induced selective lysis of tumor cells by activated natural killer (NK) cells. Furthermore, elotuzumab has been shown to directly induce NK-cell activation by binding to SLAMF7 expressed on NK cells and to indirectly modulate T-cell function by promoting the secretion of cytokines from NK cells. In combination with lenalidomide and low-dose dexamethasone, elotuzumab has shown remarkable effects in patients with relapsed or refractory multiple myeloma. In these patients, the risk of disease progression or death was significantly reduced by 30% on elotuzumab. Currently, elotuzumab is being evaluated in various myeloma patient populations and combination regimens. This review discusses the use of elotuzumab as an antimultiple myeloma agent and provides an update on the results of recent clinical trials evaluating the safety and efficacy of elotuzumab for the treatment of multiple myeloma.

Among different isotypes of MM, immunoglobulin D (IgD MM is very rare, representing only 1 to 2% of all isotypes. Chronic myelogenous leukemia (CML is a neoplastic myeloproliferative disorder of pluripotent hematopoietic stem cell, which is characterized by the uncontrolled proliferation of myeloid cells. An 88-year-old male was diagnosed simultaneously with IgD kappa MM and CML. A distinctive feature in this patient was the progression to plasma cell leukemia without any symptomatic myeloma stage. He was treated simultaneously with lenalidomide, bortezomib and imatinib. Synchronous occurrence of these rare hematological malignancies in a single patient is an exceedingly rare event. Multiple hypotheses to explain co-occurrence of CML and MM have been proposed; however, the exact etiological molecular pathophysiology remains elusive.

    We have recently shown significant renoprotective effects with the administration of pituitary adenylate cyclase-activating polypeptide (PACAP) in models of myeloma kidney. PACAP markedly inhibited the production of proinflammatory cytokines stimulated by immunoglobulin light chains in human renal proximal tubule epithelial cells and in the kidneys of rats infused with myeloma light chains. PACAP was also shown to suppress the proliferation of human kappa and lambda light chain-secreting multiple myeloma-derived cells. In this case study, an 81-year-old male patient with active multiple myeloma and myeloma kidney was infused intravenously with synthetic human PACAP38 at a rate of 4 pmol/kg/min for 120 min. The continuous infusion increased the level of PACAP38 in blood, with a plateau at about 0.2 nM during the infusion. The level of PACAP in the blood rapidly declined after the cessation of administration with a half-life of about 5-10 min. The continuous infusion did not significantly alter the basal glucose level, blood gases or blood pressure. There was a large reduction in free lambda light chains in urine after the start of the treatment with PACAP. These studies show that PACAP can be safely used in humans and suggest that it could be used as a novel therapeutic agent for the treatment of multiple myeloma and myeloma kidney.

    Recent studies show that multiple myeloma (MM) is consistently preceded by an asymptomatic precursor state. Smoldering MM (SMM) is a MM precursor defined by an M-protein concentration >or= 3 g/dL and/or >or= 10% bone marrow plasma cells, in the absence of end-organ damage. Compared with individuals diagnosed with monoclonal gammopathy of undetermined significance (MGUS), patients with SMM have a much higher annual risk of developing MM. However, based on clinical observations, the natural history of SMM varies greatly, from stable MGUS-like disease to highly progressive disease. Using conventional clinical markers, SMM patients can be stratified into 3 risk groups. Importantly, because of considerable molecular heterogeneity, we currently lack reliable markers to predict prognosis for individual SMM patients. Furthermore, until recently, potent drugs with reasonable toxicity profiles have not been available for the development of early MM treatment strategies. Consequently, current clinical guidelines emphasize the application of close clinical monitoring followed by treatment when the patient develops symptomatic MM. This review focuses on novel biomarkers, molecular profiles, and microenvironmental interactions of interest in myelomagenesis. We also discuss how the integration of novel biologic markers and clinical monitoring of SMM could facilitate the development of early treatment strategies for high-risk SMM patients in the future.

    ᅟ: FDG PET/CT ( 18 F-fluoro-deoxy-glucose positron emission tomography/computed tomography) is a useful tool to image multiple myeloma (MM). However, simple and reproducible reporting criteria are still lacking and there is the need for harmonization. Recently, a group of Italian nuclear medicine experts defined new visual descriptive criteria (Italian Myeloma criteria for Pet Use: IMPeTUs) to standardize FDG PET/CT evaluation in MM patients. The aim of this study was to assess IMPeTUs reproducibility on a large prospective cohort of MM patients. Patients affected by symptomatic MM who had performed an FDG PET/CT at baseline (PET0), after induction (PET-AI), and the end of treatment (PET-EoT) were prospectively enrolled in a multicenter trial (EMN02)(NCT01910987; MMY3033). After anonymization, PET images were uploaded in the web platform WIDEN® and hence distributed to five expert nuclear medicine reviewers for a blinded independent central review according to the IMPeTUs criteria. Consensus among reviewers was measured by the percentage of agreement and the Krippendorff's alpha. Furthermore, on a patient-based analysis, the concordance among all the reviewers in terms of positivity or negativity of the FDG PET/CT scan was tested for different thresholds of positivity (Deauville score (DS 2, 3, 4, 5) for the main parameters (bone marrow, focal score, extra-medullary disease). Eighty-six patients (211 FDG PET/CT scans) were included in this analysis. Median patient age was 58 years (range, 35-66 years), 45% were male, 15% of them were in stage ISS (International Staging System) III, and 42% had high-risk cytogenetics. The percentage agreement was superior to 75% for all the time points, reaching 100% of agreement in assessing the presence skull lesions after therapy. Comparable results were obtained when the agreement analysis was performed using the Krippendorff's alpha coefficient, either in every single time point of scanning (PET0, PET-AI or PET-EoT) or

    Functional or morphofunctional imaging modalities are used in myeloma patients for the diagnosis and therapy management within research protocols. Despite new staging criteria, which take into account the viability of a myeloma lesion, positron emission tomography (PET) is not used routinely. The impact of PET is therefore open. The role of PET and PET computed tomography (PET-CT) for the diagnosis and therapy management is discussed. The use of PET with 18F-fluorodeoxyglucose (FDG) allows the measurement of viable myeloma lesions and correlates with the stage of disease. A negative FDG examination correlates with a better prognosis. Furthermore, the number of focal lesions as well as the whole functional volume of myeloma lesions in FDG have a prognostic impact. Several studies have demonstrated the impact of FDG for the assessment of therapy monitoring and show that FDG is an earlier indicator for therapy response as compared to magnetic resonance imaging (MRI). The CT component of the new hybrid systems allows the assessment of osteolytic lesions in CT and their viability in FDG. The combination of PET with an MRT scanner allows the simultaneous measurement of bone marrow infiltration, focal lesions and their viability. The use of modern hybrid scanners, such as PET-CT and PET-MRT facilitates the simultaneous measurement of viable myeloma lesions, osteolytic lesions and bone marrow infiltration in the whole body; therefore, it is expected that these imaging modalities will play a greater role both in diagnosis and therapy management.

    Highlights: • Levels of EEN expression paralleled with the rate of cell proliferation. • EEN was involved in the proliferation and survival of multiple myeloma (MM) cells. • EEN regulated the activity of IGF-1-Akt/mTOR pathway. • EEN regulated proliferation and survival of MM cells by enhancing IGF-1 secretion. - Abstract: The molecular mechanisms of multiple myeloma are not well defined. EEN is an endocytosis-regulating molecule. Here we report that EEN regulates the proliferation and survival of multiple myeloma cells, by regulating IGF-1 secretion. In the present study, we observed that EEN expression paralleled with cell proliferation, EEN accelerated cell proliferation, facilitated cell cycle transition from G1 to S phase by regulating cyclin-dependent kinases (CDKs) pathway, and delayed cell apoptosis via Bcl2/Bax-mitochondrial pathway. Mechanistically, we found that EEN was indispensable for insulin-like growth factor-1 (IGF-1) secretion and the activation of protein kinase B-mammalian target of rapamycin (Akt-mTOR) pathway. Exogenous IGF-1 overcame the phenotype of EEN depletion, while IGF-1 neutralization overcame that of EEN over-expression. Collectively, these data suggest that EEN may play a pivotal role in excessive cell proliferation and insufficient cell apoptosis of bone marrow plasma cells in multiple myeloma. Therefore, EEN may represent a potential diagnostic marker or therapeutic target for multiple myeloma.

    Full Text Available Despite the introduction of newly developed drugs such as lenalidomide and bortezomib, patients with multiple myeloma are still difficult to treat and have a poor prognosis. In order to find novel drugs that are effective for multiple myeloma, we tested the antitumor activity of 29 phthalimide derivatives against several multiple myeloma cell lines. Among these derivatives, 2-(2,6-diisopropylphenyl-5-amino-1H-isoindole-1,3- dione (TC11 was found to be a potent inhibitor of tumor cell proliferation and an inducer of apoptosis via activation of caspase-3, 8 and 9. This compound also showed in vivo activity against multiple myeloma cell line KMS34 tumor xenografts in ICR/SCID mice. By means of mRNA display selection on a microfluidic chip, the target protein of TC11 was identified as nucleophosmin 1 (NPM. Binding of TC11 and NPM monomer was confirmed by surface plasmon resonance. Immunofluorescence and NPM knockdown studies in HeLa cells suggested that TC11 inhibits centrosomal clustering by inhibiting the centrosomal-regulatory function of NPM, thereby inducing multipolar mitotic cells, which undergo apoptosis. NPM may become a novel target for development of antitumor drugs active against multiple myeloma.

    Full Text Available O mieloma múltiplo ainda é uma doença incurável. Apesar das novas estratégias de tratamento, a maioria dos pacientes recidiva. O padrão da recidiva é muito heterogêneo, podendo se apresentar com comportamento indolente ou agressivo. O tratamento da doença recidivada depende de vários fatores: do tratamento realizado como primeira linha, se transplante autólogo de medula óssea ou não, da resposta e sua duração, se a recidiva ocorreu com ou sem tratamento de manutenção, do performance status do paciente e da reserva medular. Se a recidiva ocorrer após seis meses do término do tratamento, o mesmo esquema quimioterápico inicial pode ser instituído. O transplante autólogo de medula óssea pode ser proposto como consolidação em recidivas quimiossensíveis ou como tratamento de resgate, se as células-tronco periféricas tiverem sido coletadas anteriormente. A talidomida tem sido utilizada em pacientes com mieloma múltiplo recidivado após quimioterapia convencional ou após o transplante autólogo da medula óssea. A talidomida sozinha pode induzir respostas objetivas em pelo menos 1/3 dos pacientes que já receberam muitos tratamentos; e quando combinada com quimioterapia, as respostas objetivas ocorrem em aproximadamente 2/3 dos pacientes. O bortezomibe está indicado em pacientes recidivados, sozinho ou associado a dexametasona e a outras drogas, com taxas de resposta de 43% a 76%. O melhor tratamento do paciente com mieloma múltiplo recidivado deve ser individualizado, dependendo da idade, da função da medula óssea, da terapia inicial, do padrão e tempo para a recidiva.Multiple myeloma still remains an incurable disease.

    Full Text Available Introduction. Multiple myeloma (MM is characterized by the presence of neoplastic proliferating plasma cells. The tumor is generally restricted to the bone marrow. The most common complications include renal insufficiency, hypercalcemia, anemia and reccurent infections. The spectrum of MM neurological complications is diverse, however, involvement of MM in the cerebrospinal fluid (CSF and leptomeningeal infiltration are rare considered. In about 1% of the cases, the disease affects the central nervous system (CNS and presents itself in the form of localized intraparenchymal lesions, solitary cerebral plasmocytoma or CNS myelomatosis (LMM. Case report. We presented the clinical course of a 55-year-old man with MM and LMM proven by malignant plasma cells in the CSF, hospitalized with the pain in the thoracic spine. His medical history was uneventful. There had been no evidence of mental or neurological impairment prior to the seizures. Physical examination showed no abnormalities. After a complete staging, the diagnosis of MM type biclonal gammopathia IgG lambda and free lambda light chains in the stage III was confirmed. The treatment started with systemic chemotherapy (with vincristine, doxorubicin plus high-dose dexamethasone - VAD protocol, radiotherapy and bisphosphonate. The patient developed weakness, nausea, febrility, dispnea, bilateral bronchopneumonia, acute renal insufficiency, confusions, headaches and soon thereafter sensomotor aphasias and right hemiparesis. The patient was treated with the adequate therapy including one hemodyalisis. His neurological status was deteriorated, so Multislice Computed Tomography (MSCT of the head was performed and the findings were normal. Analysis of CSF showed pleocytosis, 26 elements/ mL and increased concentrations of proteins. Cytological analysis revealed an increased number of plasma cells (29%. Electrophoretic analysis of proteins disclosed the existance of monoclonal components in the serum

    To expand on the findings from previous clinical trials that the growth of residual tumor is increased at a predictable time following initial drug administration, malignant plasma cells from bone marrows of patients with multiple myeloma (MM) were examined for changes in proliferation and clonogenicity induced in vivo by cyclophosphamide and in vitro by drug-induced humoral stimulatory activity. Peak plasma cell [ 3 H]thymidine labeling index (LI) occurred predictably following drug and paralleled changes in agar colony formation by marrow cells obtained during therapy. Colony-forming capacity of pretreatment MM marrow populations was enhanced when those cells were cultured with humoral stimulatory activity, similar to the increased colony formation detected in Day 9 postcyclophosphamide marrows at the time of peak plasma cell LI. To further define a relationship between proliferative plasma cells and colony-forming tumor cells, MM marrows were fractionated by sedimentation on an isokinetic gradient. Enrichment of a proliferative tumor cell cohort was achieved, evidenced by [ 3 H]thymidine LI. Colony-forming cells were also enriched by isokinetic gradient sedimentation, and agar colony formation by MM marrow cell fractions correlated with the kinetic characteristics of the isolated subpopulations. These studies of whole and fractionated human MM marrow cell populations suggest that the kinetically active cells which are induced to proliferate in vivo and in vitro are closely related to the clonogenic tumor cells which produce colonies in agar and which, like those cells measured by [ 3 H]thymidine LI, respond to growth stimulation by drug-induced humoral stimulatory activity

    Full Text Available BACKGROUND: Radiation therapy (RT is a treatment modality traditionally used in patients with multiple myeloma (MM, but little is known regarding the role and effectiveness of RT in the era of novel agents, i.e, immunomodulatory drugs (IMiDs and proteasome inhibitors (PIs. METHODS: We retrospectively reviewed data from 449 consecutive MM patients seen at our institute in 2010-12 to assess indications for RT as well as its effectiveness. Pain response was scored similarly to RTOG 0631 and used the numerical rating pain scale (NRPS.RESULTS: Among 442 evaluable patients, 149 (34% patients and 262 sites received RT. The most common indication for RT was palliation of bone pain (n=109, 42%, followed by prevention/treatment of pathological fractures (n=73, 28%, spinal cord compression (n=26, 10%, and involvement of vital organs/extramedullary disease (n=25, 10%. Of the 55 patients evaluable for pain relief, complete and partial responses were obtained in 76.4% and 7.2% respectively. Prior RT did not significantly decrease the median number of peripheral blood stem cells collected for autologous transplant, even when prior RT was given to both the spine and pelvis. Inadequacy of stem cell collection for autologous stem cell transplant (ASCT was not significantly different and it occurred in 9% and 15% of patients receiving no RT and spine/pelvic RT, respectively. None of the 3 cases of therapy-induced AML/MDS occurred in the RT group.CONCLUSIONS: Despite the introduction of novel effective agents in the treatment of MM, RT remains a major therapeutic component for the management in 34% of patients, and it effectively provides pain relief while not interfering with successful peripheral blood stem cell collection for ASCT.

    The B-cell compartment in which multiple myeloma stem cells reside remains unclear. We investigated the potential presence of mature, surface-membrane immunoglobulin-positive B lymphocytes clonally related to the tumor bone marrow plasma cells among different subsets of peripheral blood B cells from ten patients (7 with multiple myeloma and 3 with monoclonal gammopathies of undetermined significance). The presence of clonotypic immunoglobulin heavy chain gene rearrangements was determined in multiple highly-purified fractions of peripheral blood B-lymphocytes including surface-membrane IgM(+) CD27(-) naïve B-lymphocytes, plus surface-membrane IgG(+), IgA(+) and IgM(+) memory CD27(+) B cells, and normal circulating plasma cells, in addition to (mono)clonal plasma cells, by a highly-specific and sensitive allele-specific oligonucleotide polymerase chain reaction directed to the CDR3 sequence of the rearranged IGH gene of tumor plasma cells from individual patients. Our results showed systematic absence of clonotypic rearrangements in all the different B-cell subsets analyzed, including M-component isotype-matched memory B-lymphocytes, at frequencies <0.03 cells/μL (range: 0.0003-0.08 cells/μL); the only exception were the myeloma plasma cells detected and purified from the peripheral blood of four of the seven myeloma patients. These results indicate that circulating B cells from patients with multiple myeloma and monoclonal gammopathies of undetermined significance are usually devoid of clonotypic B cells while the presence of immunophenotypically aberrant myeloma plasma cells in peripheral blood of myeloma patients is a relatively frequent finding.

    The rate of asymptomatic amyloidosis (AL) among patients with newly diagnosed multiple myeloma (MM) or smoldering multiple myeloma (SMM) is unknown. We evaluated number and clinical significance of asymptomatic AL in consecutive MM and SMM patients, not having recognition of symptomatic AL at the time of their diagnostic bone marrow biopsy. Bone marrow biopsies were stained with Congo red and considered diagnostic for AL in case of positive Congo red staining with apple-green birefringence. Biopsies from 144 patients were evaluated: 77 had a diagnosis of MM and 67 of SMM. The median age was 59 (range 26-84) years; the median follow-up was 76 months (range 0-216). Immunoglobulin isotypes were 96/144 (67%), IgG; 23/144 (16%), IgA; 12/144 (8%), light chain only; 1/77 (1%), IgD; and biclonal or indeterminate, 12/144 (8%). Fifty-eight percent (84/144) were κ restricted. The presence of amyloid was found in two cases (1%, 95% CI -0.6 to 3.2), one in MM, and one in SMM group, and none had or developed signs or symptoms suggestive of organ involvement by amyloid. Among the 142 other patients without amyloid deposition in their index bone marrow, one (0.7%, 95% CI -0.6 to 2.0) developed symptomatic AL after 119 months.

    Full Text Available Metastatic calcification has been associated with multiple-myeloma-induced hypercalcemia. Despite of a relatively high prevalence of metastatic pulmonary calcification in patients with multiple myeloma, only a few cases have been clinically and radiologically detected. A 45-year-old Hispanic male presented to the Emergency Department with complaint of worsening weakness and myalgia. Laboratory findings revealed renal insufficiency and hypercalcemia. CT scan of chest revealed calcified pleural and pulmonary nodule. Technetium (Tc 99 bone scan revealed diffuse activity in the pulmonary parenchyma consistent with metastatic pulmonary calcification. Metastatic pulmonary calcification, despite its high prevalence, remains undetected. This is, in part, due to its radiographic characteristic properties that evade detection by routine imaging studies. We present a case of a metastatic pulmonary calcification in a patient diagnosed with multiple myeloma and chronic kidney disease, as well as a brief literature review including clinical findings and treatment options.

    Multiple myeloma is characterized by an increased susceptibility to infections and to other malignancies. In a double-blind, placebo-controlled study the potential impact of immunomodulation by ranitidine was studied in 20 patients with multiple myeloma. Three patients were untreated, while 17...... after previous cytotoxic therapy were in a stable phase of their disease. All were without clinical signs of infections and at that time had not been treated with other immunomodulating agents. The patients were randomized to oral ranitidine 300 mg twice a day for 21 days or placebo, and several...... immunological parameters related to multiple myeloma were studied. The blood monocyte chemotactic response was improved in patients treated with ranitidine, and superoxide anion production increased from 2.02 nmol/min to 3.86 nmol/min (median values), while it was unchanged in patients given placebo (2...

    Full Text Available There have been major recent advancements in the understanding and management of multiple myeloma. Diagnostic criteria have been revised and former ultra-high-risk smoldering multiple myeloma is now considered multiple myeloma in need of treatment. Understanding clonal progression, evolution, and tides not only has helped elucidate the disease behavior but might help expand therapeutic choices in order to select appropriate treatment for patients. Unprecedented response rates with modern triplet induction therapies containing proteasome inhibitor and immunomodulators have made this approach standard for initial treatment. The US Food and Drug Administration approved four new drugs (two targeted antibodies and two oral agents in 2015 in relapsed/refractory multiple myeloma and these drugs along with the other already-available drugs have now increased the choices of regimens. Even drugs without single-agent activity, such as panobinostat and elotuzumab, have an important role, especially in the proteasome inhibitor refractory setting. Recent studies done in the context of novel agent induction suggest that high-dose therapy followed by autologous transplant continues to improve response rates and progression-free survival, thus underscoring their role in transplant-eligible patients. Evolving paradigms in the treatment of multiple myeloma include newer promising immune approaches, such as adoptive cellular therapies, vaccines, or antibody-based immune manipulations. Though multiple myeloma is still considered incurable, it is clear that with the improved understanding of disease biology and clonal architecture of relapse combined with the availability of multi-targeted approaches, we are ever closer to a lasting cure or transformation into indolent and long-lasting disease courses or both.

    We carried out a cohort study of smoldering multiple myeloma (SMM) in Japan. The clinical data of 207 patients with SMM, median age 69 years (range: 27-90), were collected from 63 institutions. The subtype of myeloma was IgG type in 168, IgA type in 30, and Bence Jones type in 9 patients. At a median follow-up of 39 months, 53% of the patients had progressed to symptomatic MM (within 5 years of the initial diagnosis). As previously described, a serum free light chain ratio>8 or <0.125, along with the number of bone marrow plasma cells being 10% or more and the serum M-protein level being at least 3 g/dl, was a significant predictor of rapid progression. We found that the rate of increase in serum M-protein levels correlated negatively with the risk of progression. The probability of progression within 5 years was 100% in patients whose rate of serum M-protein level increase was 2 mg/dl/day or higher. This indicates that the serum M-protein level increase rate might be a useful predictor of disease progression in SMM.

  6. The KISS1 Receptor as an In Vivo Microenvironment Imaging Biomarker of Multiple Myeloma Bone Disease.

    Full Text Available Multiple myeloma is one of the most common hematological diseases and is characterized by an aberrant proliferation of plasma cells within the bone marrow. As a result of crosstalk between cancer cells and the bone microenvironment, bone homeostasis is disrupted leading to osteolytic lesions and poor prognosis. Current diagnostic strategies for myeloma typically rely on detection of excess monoclonal immunoglobulins or light chains in the urine or serum. However, these strategies fail to localize the sites of malignancies. In this study we sought to identify novel biomarkers of myeloma bone disease which could target the malignant cells and/or the surrounding cells of the tumor microenvironment. From these studies, the KISS1 receptor (KISS1R, a G-protein-coupled receptor known to play a role in the regulation of endocrine functions, was identified as a target gene that was upregulated on mesenchymal stem cells (MSCs and osteoprogenitor cells (OPCs when co-cultured with myeloma cells. To determine the potential of this receptor as a biomarker, in vitro and in vivo studies were performed with the KISS1R ligand, kisspeptin, conjugated with a fluorescent dye. In vitro microscopy showed binding of fluorescently-labeled kisspeptin to both myeloma cells as well as MSCs under direct co-culture conditions. Next, conjugated kisspeptin was injected into immune-competent mice containing myeloma bone lesions. Tumor-burdened limbs showed increased peak fluorescence compared to contralateral controls. These data suggest the utility of the KISS1R as a novel biomarker for multiple myeloma, capable of targeting both tumor cells and host cells of the tumor microenvironment.

    Full Text Available Abstract Background In multiple myeloma (MM, increased neoangiogenesis contributes to tumor growth and disease progression. Increased levels of endothelial progenitor cells (EPCs contribute to neoangiogenesis in MM, and, importantly, covary with disease activity and response to treatment. In order to understand the mechanisms responsible for increased EPC levels and neoangiogenic function in MM, we investigated whether these cells were clonal by determining X-chromosome inactivation (XCI patterns in female patients by a human androgen receptor assay (HUMARA. In addition, EPCs and bone marrow cells were studied for the presence of clonotypic immunoglobulin heavy-chain (IGH gene rearrangement, which indicates clonality in B cells; thus, its presence in EPCs would indicate a close genetic link between tumor cells in MM and endothelial cells that provide tumor neovascularization. Methods A total of twenty-three consecutive patients who had not received chemotherapy were studied. Screening in 18 patients found that 11 displayed allelic AR in peripheral blood mononuclear cells, and these patients were further studied for XCI patterns in EPCs and hair root cells by HUMARA. In 2 patients whose EPCs were clonal by HUMARA, and in an additional 5 new patients, EPCs were studied for IGH gene rearrangement using PCR with family-specific primers for IGH variable genes (VH. Results In 11 patients, analysis of EPCs by HUMARA revealed significant skewing (≥ 77% expression of a single allele in 64% (n = 7. In 4 of these patients, XCI skewing was extreme (≥ 90% expression of a single allele. In contrast, XCI in hair root cells was random. Furthermore, PCR amplification with VH primers resulted in amplification of the same product in EPCs and bone marrow cells in 71% (n = 5 of 7 patients, while no IGH rearrangement was found in EPCs from healthy controls. In addition, in patients with XCI skewing in EPCs, advanced age was associated with poorer clinical status

    Advances in therapies for younger patients with multiple myeloma have resulted in significant improvements in outcome over recent years, on the contrary the progress in treatments for elderly patients has remained more modest. Traditionally, patients   who are not eligible for transplantation, like the older patients,  have been treated with the combination of melphalan plus prednisone (MP, which leads to responses in approximately 50% of patients; however, patients rarely achieve a complete response (CR and long-term outcomes are disappointing, with a relapse-free survival of approximately 18 months and an overall survival (OS of approximately 3 years.

    A retrospective analysis of 153 patients with multiple myeloma was performed for evaluation of the possible significance of pre-existing disease. 37% of the group had no significant antecedent disorder. The most common prior illnesses were peptic ulcer disease and gallbladder disease. Of 12 patients in the group who had prior biliary tract disease and for whom immunoelectrophoretic studies were available, eight (66.7%) had IgA paraproteins. This figure is statistically higher than the 14.1% of prevalence of IgA paraproteins in those myeloma patients without biliary disease. We conclude that prior inflammatory gastrointestinal, pulmonary, and, particularly, biliary disease may be implicated in the pathogenesis of the IgA subset of multiple myeloma.

    Full Text Available Testicular plasmacytomas are a rare phenomenon reported in the literature and they can occur as a solitary plasmacytoma, as a recurrence of multiple myeloma, or concurrently in an active myeloma. We report the case of a 43-year-old man who presented with back pain and was diagnosed with multiple myeloma. A CT scan performed to determine the extent of disease revealed an incidental mass in the testicle. Immunohistochemical staining of the mass revealed monoclonal cytolpasmic IgA in the tumor cells and serum studies showed this same immunoglobulin. Following orchiectomy, radiotherapy to the vertebra, chemotherapy with bortezomib, dexamethasone, and doxorubicin, and an autologous bone marrow transplant, the patient is alive twelve months after diagnosis and is in complete remission.

    Smoldering multiple myeloma (SMM) is a rare plasma cell disorder, and as the disease is asymptomatic, diagnosis is often incidental. SMM is characterized by increased marrow infiltration by clonal plasma cells and/or elevated serum M-protein in the absence of a myeloma-defining event (MDE). In recent years, SMM has gained increased attention owing to a broadening of the criteria for MDE, which include apart from the CRAB criteria, three additional parameters. Survival advantage may be offered by early treatment in the high-risk subset, based on a single trial. In this review, we assess the risk factors and models for progression to multiple myeloma. A review of our diagnostic and management approaches to SMM is presented.

    The International Myeloma Working Group consensus updates the definition for high-risk (HR) multiple myeloma based on cytogenetics Several cytogenetic abnormalities such as t(4;14), del(17/17p), t(14;16), t(14;20), nonhyperdiploidy, and gain(1q) were identified that confer poor prognosis. The prognosis of patients showing these abnormalities may vary with the choice of therapy. Treatment strategies have shown promise for HR cytogenetic diseases, such as proteasome inhibition in combination with lenalidomide/pomalidomide, double autologous stem cell transplant plus bortezomib, or combination of immunotherapy with lenalidomide or pomalidomide. Careful analysis of cytogenetic subgroups in trials comparing different treatments remains an important goal. Cross-trial comparisons may provide insight into the effect of new drugs in patients with cytogenetic abnormalities. However, to achieve this, consensus on definitions of analytical techniques, proportion of abnormal cells, and treatment regimens is needed. Based on data available today, bortezomib and carfilzomib treatment appear to improve complete response, progression-free survival, and overall survival in t(4;14) and del(17/17p), whereas lenalidomide may be associated with improved progression-free survival in t(4;14) and del(17/17p). Patients with multiple adverse cytogenetic abnormalities do not benefit from these agents. FISH data are implemented in the revised International Staging System for risk stratification.

    2012-12-01

    Full Text Available Abstract Background Multiple myeloma (MM is a plasma cell malignancy with a multifaceted immune dysfunction. Indoleamine 2,3-dioxygenase 1 (IDO1 degrades tryptophan into kynurenine (KYN, which inhibits effector T cells and promote regulatory T-cell (Treg differentiation. It is presently unknown whether MM cells express IDO1 and whether IDO1 activity correlates with immune system impairment. Methods We investigated IDO1 expression in 25 consecutive patients with symptomatic MM and in 7 patients with either monoclonal gammopathy of unknown significance (MGUS; n=3 or smoldering MM (SMM; n=4. IDO1-driven tryptophan breakdown was correlated with the release of hepatocyte growth factor (HGF and with the frequency of Treg cells and NY-ESO-1-specific CD8+ T cells. Results KYN was increased in 75% of patients with symptomatic MM and correlated with the expansion of CD4+CD25+FoxP3+ Treg cells and the contraction of NY-ESO-1-specific CD8+ T cells. In vitro, primary MM cells promoted the differentiation of allogeneic CD4+ T cells into bona fide CD4+CD25hiFoxP3hi Treg cells and suppressed IFN-γ/IL-2 secretion, while preserving IL-4 and IL-10 production. Both Treg expansion and inhibition of Th1 differentiation by MM cells were reverted, at least in part, by d,l-1-methyl-tryptophan, a chemical inhibitor of IDO. Notably, HGF levels were higher within the BM microenvironment of patients with IDO+ myeloma disease compared with patients having IDO- MM. Mechanistically, the antagonism of MET receptor for HGF with SU11274, a MET inhibitor, prevented HGF-induced AKT phosphorylation in MM cells and translated into reduced IDO protein levels and functional activity. Conclusions These data suggest that IDO1 expression may contribute to immune suppression in patients with MM and possibly other HGF-producing cancers.

  16. Spinal focal lesion detection in multiple myeloma using multimodal image features

    Science.gov (United States)

    Fränzle, Andrea; Hillengass, Jens; Bendl, Rolf

    2015-03-01

    Multiple myeloma is a tumor disease in the bone marrow that affects the skeleton systemically, i.e. multiple lesions can occur in different sites in the skeleton. To quantify overall tumor mass for determining degree of disease and for analysis of therapy response, volumetry of all lesions is needed. Since the large amount of lesions in one patient impedes manual segmentation of all lesions, quantification of overall tumor volume is not possible until now. Therefore development of automatic lesion detection and segmentation methods is necessary. Since focal tumors in multiple myeloma show different characteristics in different modalities (changes in bone structure in CT images, hypointensity in T1 weighted MR images and hyperintensity in T2 weighted MR images), multimodal image analysis is necessary for the detection of focal tumors. In this paper a pattern recognition approach is presented that identifies focal lesions in lumbar vertebrae based on features from T1 and T2 weighted MR images. Image voxels within bone are classified using random forests based on plain intensities and intensity value derived features (maximum, minimum, mean, median) in a 5 x 5 neighborhood around a voxel from both T1 and T2 weighted MR images. A test data sample of lesions in 8 lumbar vertebrae from 4 multiple myeloma patients can be classified at an accuracy of 95% (using a leave-one-patient-out test). The approach provides a reasonable delineation of the example lesions. This is an important step towards automatic tumor volume quantification in multiple myeloma.

    This study sought to identify occupations with high incidence of multiple myeloma and to investigate possible excess risk associated with occupational exposure to chemicals and sensitizing agents in Sweden. A historical cohort of 2,992,166 workers was followed up (1971--1989) through record linkage with the National Cancer and Death Registries. For each job category, age and period standardized incidence ratios and age and period adjusted relative risks of multiple myeloma were calculated using Poisson models. Exposure to chemicals and to sensitizing agents was also assessed using two job-exposure matrices. Men and women were analyzed separately. During follow-up, 3,127 and 1,282 myelomas were diagnosed in men and women, respectively. In men, excess risk was detected among working proprietors, agricultural, horticultural and forestry enterprisers, bakers and pastry cooks, dental technicians, stone cutters/carvers, and prison/reformatory officials. In women, this excess was observed among attendants in psychiatric care, metal workers, bakers and pastry cooks, and paper/paperboard product workers. Workers, particularly bakers and pastry cooks, exposed to high molecular weight sensitizing agents registered an excess risk of over 40% across the sexes. Occasional, although intense, exposure to pesticides was also associated with risk of myeloma in our cohort. Our study supports a possible etiologic role for farming and use of pesticides in myeloma risk. The high incidence found in both female and male bakers and pastry cooks has not been described previously. Further research is required to assess the influence of high molecular weight sensitizing agents on risk of multiple myeloma.

    Multiple myeloma develops primarily inside the bone marrow microenvironment, that confers pro-survival signals and drug resistance. 3D cultures that reproduce multiple myeloma-bone marrow interactions are needed to fully investigate multiple myeloma pathogenesis and response to drugs. To this purpose, we exploited the 3D Rotary Cell Culture System bioreactor technology for myeloma-bone marrow co-cultures in gelatin scaffolds. The model was validated with myeloma cell lines that, as assessed by histochemical and electron-microscopic analyses, engaged contacts with stromal cells and endothelial cells. Consistently, pro-survival signaling and also cell adhesion-mediated drug resistance were significantly higher in 3D than in 2D parallel co-cultures. The contribution of the VLA-4/VCAM1 pathway to resistance to bortezomib was modeled by the use of VCAM1 transfectants. Soluble factor-mediated drug resistance could be also demonstrated in both 2D and 3D co-cultures. The system was then successfully applied to co-cultures of primary myeloma cells-primary myeloma bone marrow stromal cells from patients and endothelial cells, allowing the development of functional myeloma-stroma interactions and MM cell long-term survival. Significantly, genomic analysis performed in a high-risk myeloma patient demonstrated that culture in bioreactor paralleled the expansion of the clone that ultimately dominated in vivo Finally, the impact of bortezomib on myeloma cells and on specialized functions of the microenvironment could be evaluated. Our findings indicate that 3D dynamic culture of reconstructed human multiple myeloma microenvironments in bioreactor may represent a useful platform for drug testing and for studying tumor-stroma molecular interactions.

    Full Text Available Abstract Daratumumab is a human monoclonal antibody that targets CD38, a cell surface protein that is overexpressed on multiple myeloma (MM cells. Preclinical studies have shown that daratumumab induces MM cell death through several mechanisms, including complement-dependent cytotoxicity (CDC, antibody-dependent cell-mediated cytotoxicity (ADCC, antibody-dependent cellular phagocytosis (ADCP, and apoptosis. Given the encouraging efficacy and acceptable safety profile of daratumumab demonstrated in clinical trials, daratumumab has emerged as a novel treatment option for myeloma and became the first monoclonal antibody approved by the FDA for the treatment of MM.

    Full Text Available In multiple myeloma, there are many factors influencing the growth of the malignant clone in direct and indirect manners. BAFF is a growth factor for myeloma cells. The aim of the study was to measure its circulating levels in 54 pretreatment patients, along with serum levels of other proliferation markers, such as interleukins-6, -10, and -15, CRP, and beta-2 microglobulin, as well as bone marrow plasma cell infiltration and expression of Ki-67 PI, in various stages of the disease and after effective treatment in 28 of them. Serum levels of the previously mentioned factors were measured by ELISA, whereas bone marrow plasma cell infiltration and Ki-67 expression were estimated immunohistochemically. All measured parameters were higher in pretreated myeloma patients compared to healthy population and were also increasing with the progression of the disease. They all also decreased after effective therapy. Furthermore, all pretreatment values correlated to each other. BAFF seems to be an important growth factor for myeloma plasma cells. Measuring its serum levels, along with the previously mentioned cytokines, may provide important information regarding the degree of myeloma cells’ proliferation. Therefore, they all could be used as markers of proliferation and disease activity.

    The experience of living with relapsed Multiple Myeloma (myeloma) for eight patients accessing treatment within a haematology unit in a large London hospital is explored in this study. Myeloma is recognised as incurable and is sometimes described as an \\'incurable chronic disease\\' with a main treatment option of chemotherapy. Hermeneutic phenomenology was the methodology used in conducting the study and data were collected through open-ended, unstructured interviews. Findings suggest that living with relapsed myeloma in the context of a chronic illness causes an ever-shifting perspective between illness and wellness consequently maintaining a state of uncertainty. The patients in this study placed importance on the emotional aspect of their experience. Hope, intuitive knowing and a fighting spirit were expressed as required positive elements that enabled living with relapsed myeloma. These assisted in maintaining normality, coping with bad news and adjusting to the illness. Pervading through the themes was the need to control uncertainty. Having strong support from significant others provided something to live for and the necessary social support required to promote a new orientation to life.

  2. Systemic therapy with oncolytic myxoma virus cures established residual multiple myeloma in mice

    Eric Bartee

    2016-01-01

    Full Text Available Multiple myeloma is an incurable malignancy of plasma B-cells. Traditional chemotherapeutic regimes often induce initial tumor regression; however, virtually all patients eventually succumb to relapse caused by either reintroduction of disease during autologous transplant or expansion of chemotherapy resistant minimal residual disease. It has been previously demonstrated that an oncolytic virus known as myxoma can completely prevent myeloma relapse caused by reintroduction of malignant cells during autologous transplant. The ability of this virus to treat established residual disease in vivo, however, remained unknown. Here we demonstrate that intravenous administration of myxoma virus into mice bearing disseminated myeloma results in the elimination of 70–90% of malignant cells within 24 hours. This rapid debulking was dependent on direct contact of myxoma virus with residual myeloma and did not occur through destruction of the hematopoietic bone marrow niche. Importantly, systemic myxoma therapy also induced potent antimyeloma CD8+ T cell responses which localized to the bone marrow and were capable of completely eradicating established myeloma in some animals. These results demonstrate that oncolytic myxoma virus is not only effective at preventing relapse caused by reinfusion of tumor cells during stem cell transplant, but is also potentially curative for patients bearing established minimal residual disease.

    Multiple myeloma (MM) remains a largely incurable, genetically heterogeneous plasma-cell malignancy that contains - just like many other cancers - a small fraction of clonogenic stem cell-like cells that exhibit pronounced self-renewal and differentiation capacities, but also pronounced drug resistance. These MM stem cells (MMSCs) are a controversial but highly significant issue in myeloma research because, in our opinion, they are at the root of the failure of anti-neoplastic chemotherapies to transform myeloma to a manageable chronic disease. Several markers including CD138-, ALDH1+ and SP have been used to identify MMSCs; however, no single marker is reliable for the isolation of MMSC. Nonetheless, it is now known that MMSCs depend on self-renewal and pro-survival pathways, such as AKT, Wnt/β-catenin, Notch and Hedgehog, which can be targeted with novel drugs that have shown promise in pre-clinical and clinical trials. Here, we review the pathways of myeloma "stemness", the interactions with the bone marrow microenvironment that promote drug resistance, and the obstacles that must be overcome to eradicate MMSCs and make myeloma a curable disease.

    The novel clinical data for plasma cell neoplasms (smoldering myeloma, multiple myeloma (MM) and AL-amyloidosis) that were presented in the 2016 Annual Meeting of the American Society of Hematology are summarized here. Data from large phase 3 studies for newly diagnosed MM patients who are eligible for autologous transplantation (EMN02, MRC XI and StaMINA trials) are described along with the results of phase 2 studies using novel anti-myeloma drug combinations for induction, consolidation and maintenance as first line therapy. Recent updates of previous important studies in the field of both newly diagnosed (FIRST) and relapsed/refractory MM (POLLUX, CASTOR) are also reported. Moreover, the results of clinical studies with the use of anti-myeloma drugs with new mechanisms of action, including pembrolizumab, selinexor, venetoclax and monoclonal antibodies, are discussed. All these data provide the basis for possible changes in the way we manage myeloma in the near future trying to "cure" the disease. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. Evidences of early senescence in multiple myeloma bone marrow mesenchymal stromal cells.

    Directory of Open Access Journals (Sweden)

    Thibaud André

    Full Text Available BACKGROUND: In multiple myeloma, bone marrow mesenchymal stromal cells support myeloma cell growth. Previous studies have suggested that direct and indirect interactions between malignant cells and bone marrow mesenchymal stromal cells result in constitutive abnormalities in the bone marrow mesenchymal stromal cells. DESIGN AND METHODS: The aims of this study were to investigate the constitutive abnormalities in myeloma bone marrow mesenchymal stromal cells and to evaluate the impact of new treatments. RESULTS: We demonstrated that myeloma bone marrow mesenchymal stromal cells have an increased expression of senescence-associated β-galactosidase, increased cell size, reduced proliferation capacity and characteristic expression of senescence-associated secretory profile members. We also observed a reduction in osteoblastogenic capacity and immunomodulatory activity and an increase in hematopoietic support capacity. Finally, we determined that current treatments were able to partially reduce some abnormalities in secreted factors, proliferation and osteoblastogenesis. CONCLUSIONS: We showed that myeloma bone marrow mesenchymal stromal cells have an early senescent profile with profound alterations in their characteristics. This senescent state most likely participates in disease progression and relapse by altering the tumor microenvironment.

    Magnetic resonance imaging (MRI) is the most sensitive imaging technique for the detection of bone marrow infiltration, and has therefore recently been included in the new diagnostic myeloma criteria, as proposed by the International Myeloma Working Group. Nevertheless, conventional MRI only provides anatomical information and is therefore only of limited use in the response assessment of patients with multiple myeloma. The additional information from functional MRI techniques, such as diffusion-weighted imaging and dynamic contrast-enhanced MRI, can improve the detection rate of bone marrow infiltration and the assessment of response. This can further enhance the sensitivity and specificity of MRI in the staging of multiple myeloma patients. This article provides an overview of the technical aspects of conventional and functional MRI techniques with practical recommendations. It reviews the diagnostic performance, prognostic value, and role in therapy assessment in multiple myeloma and its precursor stages. (orig.)

    The spectrum of kidney disease-associated monoclonal immunoglobulin and plasma cell malignancies is remarkably broad and encompasses nearly all nephropathologic entities. Multiple myeloma with kidney impairment at presentation is a medical emergency since the recovery of kidney function is associated with survival benefits. In most cases, kidney impairment may be the first clinical manifestation of malignant plasma cell dyscrasias like multiple myeloma and light chain amyloidosis. Multiple myeloma per se cannot be considered a main risk factor for developing acute kidney injury following intravascular administration of iodinated contrast media. The risk is increased by comorbidities such as chronic kidney disease, diabetes, hypercalcemia, dehydration, and use of nephrotoxic drugs. Before the administration of contrast media, the current recommended laboratory tests for assessing kidney function are serum creatinine measurement and the estimation of glomerular filtration rate by using the CKD-EPI equation. The assessment of Bence Jones proteinuria is unnecessary for evaluating the risk of kidney failure in patients with multiple myeloma, since this test cannot be considered a surrogate biomarker of kidney function.

    Full Text Available Abstract Background Bisphosphonate-associated osteonecrosis of the jaws (BP-ONJ is an adverse effect of bisphosphonate treatment with varying reported incidence rates. Methods In two neighboring German cities, prevalence and additional factors of the development of BP-ONJ in multiple myeloma patients with bisphosphonates therapy were recorded using a retrospective (RS and cross-sectional study (CSS design. For the RS, all patients treated from Jan. 2000 - Feb. 2006 were contacted by letter. In the CSS, all patients treated from Oct. 2006 - Mar. 2008 had a physical and dental examination. Additionally, a literature review was conducted to evaluate all articles reporting on BP-ONJ prevalence. PubMed search terms were: bisphosphonat, diphosphonate, osteonecrosis, prevalence and incidence. Results In the RS, data from 81 of 161 patients could be obtained; four patients (4.9% developed BP-ONJ. In the CSS, 16 of 78 patients (20.5% developed BP-ONJ. All patients with BP-ONJ had received zoledronate; 12 of these had had additional bisphosphonates. All except one had an additional trigger factor (tooth extraction [n = 14], dental surgical procedure [n = 2], sharp mylohyoid ridge [n = 3]. Conclusion The prevalence of BP-ONJ may have been underestimated to date. The oral examination of all patients in this CSS might explain the higher prevalence, since even early asymptomatic stages of BP-ONJ and previously unnoticed symptomatic BP-ONJ were recorded. Since nearly all patients with BP-ONJ had an additional trigger factor, oral hygiene and dental care might help to reduce BP-ONJ incidence.

    11 C-methionine (MET) has recently emerged as an accurate marker of tumor burden and disease activity in patients with multiple myeloma (MM). This dual-center study aimed at further corroboration of the superiority of MET as positron emission tomography (PET) tracer for staging and re-staging MM, as compared to 18 F-2`-deoxy-2`-fluoro-D-glucose (FDG). 78 patients with a history of solitary plasmacytoma (n=4), smoldering MM (SMM, n=5), and symptomatic MM (n=69) underwent both MET- and FDG-PET/computed tomography (CT) at the University Centers of Würzburg, Germany and Navarra, Spain. Scans were compared on a patient and on a lesion basis. Inter-reader agreement was also evaluated. In 2 patients, tumor biopsies for verification of discordant imaging results were available. MET-PET detected focal lesions (FL) in 59/78 subjects (75.6%), whereas FDG-PET/CT showed lesions in only 47 patients (60.3%; p<0.01), accordingly disease activity would have been missed in 12 patients. Directed biopsies of discordant results confirmed MET-PET/CT results in both cases. MET depicted more FL in 44 patients (56.4%; p<0.01), whereas in two patients (2/78), FDG proved superior. In the remainder (41.0%, 32/78), both tracers yielded comparable results. Inter-reader agreement for MET was higher than for FDG (κ = 0.82 vs κ = 0.72). This study demonstrates higher sensitivity of MET in comparison to standard FDG to detect intra- and extramedullary MM including histologic evidence of FDG-negative, viable disease exclusively detectable by MET-PET/CT. MET holds the potential to replace FDG as functional imaging standard for staging and re-staging of MM.

    The most commonly used techniques to measure vitamin D are automated immunoassays which are known to be affected by interferences, especially from immunoglobulins present in the patient's serum. We present a case of a patient with myeloma in whom interference with the vitamin D assay was identified. An 83-year-old female, known to have IgG myeloma, was found to have a high concentration of 25-OH vitamin D on a routine test without any signs of vitamin D toxicity. She was not taking vitamin D supplements or any other multivitamin preparation and had minimal sun exposure. The initial and subsequent samples run by the ARCHITECT 25-OH vitamin D assay (chemiluminescent microparticle immunoassay technology, Abbott Laboratories, Abbott Park, IL) showed a high concentration of 25-OH vitamin D of 281 nmol/L and 327 nmol/L, respectively. Further fresh samples taken for 25-OH vitamin D and analysed by liquid chromatography-mass spectrometry (LC-MS/MS) and ARCHITECT analysis showed results of 49 nmol/L and 289 nmol/L, respectively. Our patient had high concentrations of circulating IgG paraproteins and had a long history of rheumatoid arthritis; paraproteins and rheumatoid factor may interfere in the assay. In conclusion, we report a case of a patient with IgG myeloma and rheumatoid arthritis with high concentrations of 25-OH vitamin D detected by the Abbott ARCHITECT, but not by a reference method (LC-MS/MS). The most likely cause of the discordant results is interference in the immunoassay by the paraprotein but interference from rheumatoid factor remains a possibility.

    The estimated involvement of the central nervous system in patients with multiple myeloma is rare at about 1%. The infiltration can be identified at the time multiple myeloma is diagnosed or during its progression. However, it is more common in refractory disease or during relapse. This retrospective cohort study reviewed data from medical records of patients followed up at the Gammopathy Outpatient Clinic of Santa Casa de Misericórdia de São Paulo from January 2008 to December 2016. Twenty patients were included, with a median follow-up of 33.5 months after central nervous system infiltration. The prevalence was 7%. The median age at diagnosis of multiple myeloma was 56.1 years, with 70% of participants being female. Sixteen patients had central nervous system infiltration at diagnosis of multiple myeloma. Seventeen patients had exclusive osteodural lesions and three had infiltrations of the leptomeninge, of which one had exclusive involvement and two had associated osteodural lesions. The median overall survival was 40.3 months after central nervous system involvement. The median overall survival in the group with central nervous system infiltration at relapse was 7.4 months. The patients with leptomeningeal involvement had a median overall survival of 5.8 months. Central nervous system infiltration is a rare condition, but it should be considered as a possibility in patients with multiple myeloma and neurological symptoms. The best treatment regimen for this condition remains unknown and, in most cases, the prognosis is unfavorable. Copyright © 2017. Published by Elsevier Editora Ltda.

    Full Text Available Vikas A Gupta, Ajay K Nooka, Sagar Lonial, Lawrence H BoiseDepartment of Hematology and Medical Oncology, Winship Cancer Institute, Emory University School of Medicine, Atlanta, GA, USAAbstract: Treatment of refractory and/or relapsed multiple myeloma has been a challenging problem for over 20 years. However, we have made significant progress addressing this disease with the use of bortezomib, the first in class proteasome inhibitor, and the immunomodulatory agents, thalidomide and lenalidomide. Carfilzomib, the second-generation proteasome inhibitor, has also been approved for treatment of relapsed/refractory multiple myeloma. Carfilzomib is a highly selective and potent inhibitor of proteasome chymotrypsin-like activity. Phase I and II clinical trials have reported an acceptable toxicity profile, with manageable thrombocytopenia and anemia being the most common side effects. Peripheral neuropathy, a frequent dose-limiting side effect of bortezomib, was rare. Further, carfilzomib demonstrated encouraging single-agent activity and appeared to be effective even in patients refractory to bortezomib. Based on these promising data, carfilzomib is moving forward into Phase III trials for relapsed multiple myeloma and is also being investigated as front-line combination therapy for patients with newly diagnosed myeloma.Keywords: proteasome inhibitor, bortezomib, pharmacology, safety, efficacy

However, patients who relapse after treatment with these agents or are refractory to them represent an unmet need and highlight the necessity for the development of novel anti-myeloma agents. Pomalidomide is an IMiD, structurally related to thalidomide, with enhanced antiangiogenic, antineoplastic, and anti-inflammatory properties and exhibiting potent anti-myeloma activity in vitro and in vivo. Pomalidomide has shown remarkable activity in patients who were refractory to both bortezomib and lenalidomide in Phase II and III studies.

    To evaluate the association between personal hair dye use and risk of multiple myeloma among women. A population-based case-control study of 175 cases of multiple myeloma and 679 controls. Cases and controls were interviewed regarding the type and colour of hair colouring product used, age at first use, age use stopped, duration, and the frequency of use per year. Odds ratios (ORs) and 95% confidence intervals (CI) were estimated using unconditional logistic regression to compare never users with four exposure groups: all users, ever semi-permanent dye users, ever permanent dye users and dark permanent dye users (most frequent use). No association was found between ever reporting hair colouring product use and myeloma risk among all users (OR 0.8; 95% CI 0.5 to 1.1), semi-permanent dye users (OR 0.7; 95% CI 0.4 to 1.2), permanent dye users (OR 0.8; 95% CI 0.5 to 1.1) or dark permanent dye users (OR 0.8; 95% CI 0.5 to 1.3). There were no significant associations among women who used hair dyes before 30 years of age, started use before 1980, had >or=240 lifetime applications, or had used dark permanent dye for 28 or more years. No evidence of an association between hair colouring product use and myeloma risk was found. However, given the conflicting body of literature on hair colouring product use and risk of multiple myeloma, this question should be further evaluated in larger studies or consortia, and in high risk groups.

Despite the significant advances, challenges remain on which combination strategies will provide the optimal response for any given patient. Defining optimal combination strategies and corresponding companion diagnostics, that will guide clinical decisions are required to target relapsed or refractory multiple myeloma (RRMM in order to improve disease progression, survival and quality of life for patients with MM. Elotuzumab is a humanized monoclonal antibody that targets signaling lymphocytic activation molecule F7 (SLAMF7, approved by the US Food and Drug Administration (FDA in 2015 and the European Medicines Agency in 2016 for the treatment of MM. SLAMF7 is expressed in normal and malignant plasma cells and has lower expression on natural killer (NK cells. Experimental evidence indicates that elotuzumab exhibits anti-myeloma activity through 1 antibody-dependent cell-mediated cytotoxicity, 2 enhancing NK cells cytotoxicity and 3 interfering with adhesion of MM cells to bone marrow stem cells (BMSCs. Although elotuzumab has no single agent activity in patients with RRMM who have received one to three prior therapies, the combination of elotuzumab with anti-myeloma agents, such as immunomodulatory drugs-lenalidomide, or proteasome inhibitors (PIs-bortezomib, remarkably improved the overall response rates and progression-free survival in MM patients with only minimal incremental toxicity. In brief, the clinical data for elotuzumab indicate that targeting SLAMF7 in combination with the use of conventional therapies is feasible and

CD38 is a 46 kDa type II transmembrane glycoprotein that is highly expressed on myeloma cells. Daratumumab is a first in-class human IgG1 monoclonal antibody that targets CD38, and has antimyeloma effects through several mechanisms. Single-agent trials show surprising activity in heavily pretreated myeloma patients. Trials in the relapsed setting, where daratumumab is added to lenalidomide and dexamethasone or bortezomib and dexamethasone, have demonstrated significantly improved progression-free survival with acceptable toxicity. In this review, we discuss the mechanism of action, pharmacology and pharmacokinetics of daratumumab and review the available clinical data in detail. We examine how daratumumab interferes with transfusion testing due to the expression of CD38 on the red blood cells, leading to potential difficulties releasing blood products. Daratumumab also affects disease assessments in multiple myeloma, including serum protein electrophoresis, immunofixation and flow cytometry. Strategies to mitigate these effects are discussed. The optimal use of daratumumab has yet to be decided, and several trials are ongoing in the relapsed and upfront setting. We discuss the potential upfront role of this exciting therapy, which has significant potential for increased minimal residual disease negativity and improved progression-free survival even in high-risk groups.

    Multiple myeloma is a clonal neoplastic proliferation of terminally differentiated B-lymphocytes involving the skeletal system in a multifocal fashion. Its oral manifestations are less common in the maxilla than in the mandible due to the lower amount of hemopoietic bone marrow in the maxilla. We report the case of a 50-year-old man who presented with a mass in the left maxillary alveolar region with tooth mobility. The mass had become enlarged after the teeth were extracted 15 days previously. Radiographs demonstrated multiple punched-out radiolucent lesions in the skull and pelvic region. Computed tomography images showed a soft tissue density mass in the left maxilla, eroding the floor and walls of the maxillary sinus. Although several analytical techniques were used to characterize the lesion, it was finally confirmed as multiple myeloma through immunohistochemistry.

    Accessibility to innovative multiple myeloma therapies is limited in sub-Saharan Africa. This study aimed to describe the diagnostic and evolutionary features observed during treatment of our patients with myeloma. We conducted a retrospective, descriptive, analytical study (2005 - 2016) of patients with myeloma included in the study based on International Myeloma Working Group (IMWG) Criteria (2003,2014) at the Hopital Aristide Le Dantec (Senegal). We collected data from 136 medical records (69 men, 67 women) of patients with an average age of 59 years ± 10.1 years, who were less than 65 years of age in 69.1% of cases. Tell-tale signs included bone pain (96.3%), renal failure (36.8%), infection (23.5%), pathological fracture (17.6%), spinal cord compression (16.9%) and malignant hypercalcaemia (16.2%). Isotopic antiglobulin test showed that anti-IgG could be detected in 61.3% of cases and Kappa in 65% of cases. Patients were classified stage III (59.4%) and I-II (40.6%)of the index staging system. The median survival of patients under conventional traitement (Méphalan-Prédnisone: 67.6%, innovative: 5.9%) was 20 months (1-78 months). Survival rates are better in the absence of neurological and infectious complications and for patients with score I-II of the index Staging System. In our study, multiple myeloma was frequently diagnosed before age 65, at advanced stage of tumor mass. Early detection and access to adequate therapies could improve overall survival.

    Imaging studies are essential for both diagnosis and initial staging of multiple myeloma, as well as for differentiation from other monoclonal plasma cell diseases. Apart from conventional radiography, a variety of newer imaging modalities including whole-body low-dose-CT, whole-body MRI and 18F-FDG PET/CT may be used for detection of osseous and extraosseous myeloma manifestations. Despite of known limitations such as limited sensitivity and specificity and the inability to detect extraosseous lesions, conventional radiography still remains the gold standard for staging newly diagnosed myeloma, partly due to its wide availability and low costs. Whole-body low-dose CT is increasingly used due to its higher sensitivity for the detection of osseous lesions and its ability to diagnose extraosseous lesions, and is replacing conventional radiography at selected centres. The highest sensitivity for both detection of bone marrow disease and extraosseous lesions can be achieved with whole-body MRI or 18F-FDG PET/CT. Diffuse bone marrow infiltration may be visualized by whole-body MRI with high sensitivity. Whole-body MRI is at least recommended in all patients with normal conventional radiography and in all patients with an apparently solitary plasmacytoma of bone. To obtain the most precise readings, optimized examination protocols and dedicated radiologists and nuclear medicine physicians familiar with the complex and variable morphologies of myeloma lesions are required.

                Allografting is a potentially curative treatment for a subset of multiple myeloma patients for its well documented graft-vs-myeloma effects. However, its role has been hotly debated. Even though molecular remissions have been reported up to 50% after high-dose myeloablative conditionings, their applications, given the high toxicity, have been for long limited to younger relapsed/refractory patients. These limitations have greatly been reduced through the introduction of non-myeloablative/reduced-intensity conditionings.             The introduction of new drugs, characterised by low risks of early mortality, indeed requires to define role and timing of an allograft to capture the subset of patients who may most benefit from graft-vs-myeloma effects.   Ultimately, new drugs should not be viewed as mutually exclusive with an allograft. They may be employed to achieve profound cytoreduction before and enhance graft-versus-myeloma effects as consolidation/maintenance therapy after an allograft. However, this combination should be explored only in well-designed clinical trials.

    Recent innovations in the development of systemic and targeted therapies have improved survival and quality of life in multiple myeloma (MM) patients. However, in most cases, this hematological malignancy of monoclonal B-lymphocytes remains incurable. Exaggerated Wnt/β-catenin signaling has been demonstrated in lymphoma and MM, therefore targeting related signaling molecules might represent a promising therapy approach. Griseofulvin, a widely used antifungal drug, is chemically related to other known Wnt-inhibitors and we recently demonstrated its potent in vivo efficacy in a murine myeloma model. The anti-tumor apoptotic effect of griseofulvin at doses ranging from 0.1-200 μM was investigated on a total of ten human and two murine myeloma/lymphoma cell lines, as determined by 3'3-dihexyloxacarbocyanine iodide (DiOC6) and propidium iodide (PI) staining in flow cytometry. Griseofulvin significantly induced apoptosis in all investigated myeloma and lymphoma cell lines in a dose-dependent manner, while healthy control cells were less sensitive. Given the known safety profile and apoptosis induction at low effective doses, our data warrant further in vitro and in vivo studies utilizing griseofulvin as a potential therapy agent for MM and lymphoma.

The only US Food and Drug Administration approved proteasome inhibitor so far, bortezomib effectively targets the constitutive proteasome subunit ß5 of the 26S proteasome. Bortezomib induces high and quality response rates that are durable. However, myeloma cells acquire resistance to bortezomib through various mechanisms. Further, grade 3/4 peripheral neuropathy is seen in up to a quarter of patients treated with bortezomib. While the recent change in the mode of administration via the subcutaneous route is associated with a lower incidence of grade 3/4 peripheral neuropathy, it remains a major concern. The second generation proteasome inhibitors are promising, with increased preclinical efficacy and a better administration schedule. The current review spotlights the second generation proteasome inhibitors with special focus on the safety and efficacy of carfilzomib, an epoxyketone with lesser peripheral neuropathy, which exhibits irreversible proteasome inhibition. In this article, we review the pharmacology and preclinical and clinical efficacy and safety of carfilzomib alone and in combination with other chemotherapeutic agents in the various lymphoid neoplasms and multiple myeloma as well as ongoing clinical trials.Keywords: myeloma, carfilzomib, second generation, proteasome inhibitor, epoxyketone

Approval was on the basis of results from the phase 3, double-blind, placebo-controlled TOURMALINE-MM1 study, which demonstrated a 35% improvement in progression-free survival with the all-oral combination of ixazomib plus lenalidomide–dexamethasone versus lenalidomide–dexamethasone alone (median: 20.6 vs 14.7 months; hazard ratio: 0.74, p=0.012; median follow-up 14.7 months. The addition of ixazomib to the lenalidomide–dexamethasone regimen was associated with limited additional toxicity and had no adverse impact on patient-reported quality of life. Common grade ≥3 adverse events with ixazomib include gastrointestinal adverse events, rash, and thrombocytopenia. Here, we review the efficacy, safety, pharmacokinetics, and patient-reported quality of life data seen with ixazomib, and discuss the role of this oral agent in the treatment of patients with relapsed/refractory multiple myeloma, including in patients with high-risk cytogenetic abnormalities and those with multiple prior therapies.

    Bisphosphonates are specific inhibitors of osteoclastic activity and are used in the treatment of patients with multiple myeloma (MM). While bisphosphonates are shown to be effective in reducing vertebral fractures and pain, their role in improving overall survival (OS) remains unclear. This is an update of a Cochrane review first published in 2002 and previously updated in 2010 and 2012. To assess the evidence related to benefits and harms associated with use of various types of bisphosphonates (aminobisphosphonates versus non-aminobisphosphonates) in the management of patients with MM. Our primary objective was to determine whether adding bisphosphonates to standard therapy in MM improves OS and progression-free survival (PFS), and decreases skeletal-related morbidity. Our secondary objectives were to determine the effects of bisphosphonates on pain, quality of life, incidence of hypercalcemia, incidence of bisphosphonate-related gastrointestinal toxicities, osteonecrosis of jaw (ONJ) and hypocalcemia. We searched MEDLINE, Embase (September 2011 to July 2017) and the CENTRAL (2017, Issue 7) to identify all randomized controlled trial (RCT) in MM up to July 2017 using a combination of text and MeSH terms. Any randomized controlled trial (RCT) comparing bisphosphonates versus placebo/no treatment/bisphosphonates and observational studies or case reports examining bisphosphonate-related ONJ in patients with MM were eligible for inclusion. Two review authors extracted the data. Data were pooled and reported as hazard ratio (HR) or risk ratio (RR) using a random-effects model. We used meta-regression to explore statistical heterogeneity. Network meta-analysis using Bayesian approach was conducted. In this update, we included four new studies (601 participants), resulting in a total of 24 included studies.Twenty RCTs compared bisphosphonates with either placebo or no treatment and four RCTs involved another bisphosphonate as a comparator.

    To develop a magnetic resonance (MR) exploratory technique equivalent to serial bone X-ray, and to compare their precision in the staging of multiple myeloma (MM) patients. Multiple acquisition T1-weights TSE and STIR sequences in the coronal plane were performed. Ten healthy volunteers and 11 multiple myeloma diagnosed patients were included. The visualization of bony structures was particularly noted,with special attention given to those which would normally be included in a serial bone X-ray. In the case of the patients, a comparison was made between diagnostic capacities of the MR sequences. MR highlighters significantly more (p<0.05) bony elements than did the serial bone X-ray. This was greatly due to a sequential displacement of the scanner bed, allowing for field-of-views which were minimally from head to third proximal of the leg. Magnetic resonance detected a significantly higher number (p<0.05) of lesions. It was, in turn, capable of revealing greater lesion extensions, even to the point of implying staging classification changes in 18% of the patients. The utilization of whole-body MR techniques in multiple myeloma patients is feasible and clinically beneficial. MR is both more sensitive and more specific than serial bone X-ray for evaluation of bony lesions in MM. It is currently serving as a valid alternative in a growing numbers of patients.

    This case report describes a 54-year-old, asymptomatic man who presented with hyperkalemia on routine lab testing who was later found to have acute renal failure, unresponsive to fluid resuscitation, with minimal improvement after hemodialysis. After a comprehensive evaluation ruled out common causes of acute renal failure, the patient underwent testing with a bone survey, urine protein electrophoresis (UPEP), serum protein electrophoresis (SPEP), and immunoelectrophoresis for suspected plasma cell dyscrasia and received plasmapheresis for hyperviscosity syndrome and nephrotoxicity, which resulted in improved renal function. Lab results showed monoclonal gammopathy, elevated serum free light chains, and Bence Jones protein in the urine with a follow-up bone marrow biopsy indicating plasma cell dyscrasia. The patient received a diagnosis of multiple myeloma (MM) and was started on chemotherapy and immunosuppression. In patients presenting with acute renal failure with an evaluation ruling out prerenal and postrenal causes, multiple myeloma should be considered.

    Black brown hyperpigmentation of the mucosae, sun exposed skin, palmar creases and frictional sites (Addisonian pigmentation) is characteristic of Addison disease. However, it can also occur as a para neoplastic manifestation of tumours like bronchogenic carcinoma. Acquired ichthyosis starts later in life and can also be a para neoplastic presentation.We report a unique combination of para neoplastic Addisonian pigmentation and acquired ichthyosis as presenting features in a patient with undiagnosed multiple myeloma. To the best of our knowledge this combination of para neoplastic dermatosis has not been documented before in multiple myeloma. It is concluded that the presence of more than one suspicious dermatosis may be an indicator of being para neoplastic requiring necessary work-up. (author)

    Monoclonal gammopathies are a group of disorders characterized by stable or progressive clonal proliferation of plasma cells producing similar immunoglobulins. Multiple myeloma is characteristic of the presence of bone marrow infiltration by plasma cells, osteolytic lesions, and M component in serum or urine. As cancer cells multiply, they can cause pain and destruction of bone, and if affecting the spine, they can press on nerves causing pain and paresthesias. In patients of advanced age (average 69 years) with bone pain not associated with trauma, and which does not improve with treatment, a differential diagnosis should be performed with multiple myeloma. This should include, at least, a full blood count, biochemistry, total protein, protein electrophoresis, immunofixation, and radiographs of painful areas.

    Full Text Available Here, we describe the case of a 66-year-old male diagnosed with multiple myeloma who presented with generalized tonic-clonic seizures. Magnetic resonance imaging demonstrated a right solid extra-axial parieto-occipital lesion with typical characteristics of meningeal myelomatosis. Biopsy was performed, which diagnosed a dural plasmacytoma. Because of this, we started concomitant therapy with radiotherapy and lenalidomide, but the patient has a poor response to treatment and died few weeks after its initiation. Myelomatous involvement of the dura mater is a rare occurrence, given that only few cases were reported in the English literature. This presentation confers an ominous prognosis and must be a suspect diagnosis in patients diagnosed with multiple myeloma presenting neurological symptoms.

    2011-01-01

    Over the last few decades therapy for multiple myeloma has improved remarkably. In particular, the introduction of novel agents has allowed improved response rates prior to, and after, stem cell transplantation with extension of progression-free survival in high-risk patients. Nevertheless, most patients relapse, leaving multiple myeloma an incurable disease. Despite being the only treatment option that has real curative potential, allogeneic transplantation has not shown its superiority to autologous transplantation due to its high morbidity and mortality rates. This review highlights how novel agents might help to reduce treatment-related mortality and to improve tumor control prior to and post-allogeneic stem cell transplant, which will hopefully result in significantly improved long-term disease control, and maybe a cure following this treatment modality.

    Full Text Available The aim of this study was to evaluate the diagnostic and differential diagnostic power of serum N-glycans for light chain multiple myeloma (LCMM. A total of 167 cases of subjects, including 42 LCMM, 42 IgG myeloma, 41 IgA myeloma, and 42 healthy controls were recruited in this study. DNA sequencer-assisted fluorophore-assisted capillary electrophoresis (DSA-FACE was applied to determine the quantitive abundance of serum N-glycans. The core fucosylated, bisecting and sialylated modifications were analyzed in serum of LCMM patients (n=20 and healthy controls (n=20 randomly selected from the same cohort by lectin blot. Moreover, serum sialic acid (SA level was measured by enzymatic method. We found two N-glycan structures (NG1A2F, Peak3; NA2FB, Peak7 showed the optimum diagnostic efficacy with area under the ROC curve (AUC 0.939 and 0.940 between LCMM and healthy control. The sensitivity and specificity of Peak3 were 88.1% and 92.9%, while Peak7 were 92.9% and 97.6%, respectively. The abundance of Peak3 could differentiate LCMM from IgG myeloma with AUC 0.899, sensitivity 100% and specificity 76.2%, and Peak7 could be used to differentiate LCMM from IgA myeloma with AUC 0.922, sensitivity 92.9% and specificity 82.9%. Serum SA level was significantly higher in patients with LCMM than that in healthy controls. Moreover, the decreased core fucosylation, bisecting and increased sialylation characters of serum glycoproteins were observed in patients with LCMM. We concluded that serum N-glycan could provide a simple, reliable and non-invasive biomarker for LCMM diagnosis and abnormal glycosylation might imply a new potential therapeutic target in LCMM.

    Exposure to diagnostic x-rays and the risk of leukemia, non-Hodgkin's lymphoma (NHL), and multiple myeloma were studied within two prepaid health plans. Adult patients with leukemia (n = 565), NHL (n = 318), and multiple myeloma (n = 208) were matched to controls (n = 1390), and over 25,000 x-ray procedures were abstracted from medical records. Dose response was evaluated by assigning each x-ray procedure a score based on estimated bone marrow dose. X-ray exposure was not associated with chronic lymphocytic leukemia, one of the few malignant conditions never linked to radiation (relative risk [RR], 0.66). For all other forms of leukemia combined (n = 358), there was a slight elevation in risk (RR, 1.17) but no evidence of a dose-response relationship when x-ray procedures near the time of diagnosis were excluded. Similarly, patients with NHL were exposed to diagnostic x-ray procedures more often than controls (RR, 1.32), but the RR fell to 0.99 when the exposure to diagnostic x-ray procedures within 2 years of diagnosis was ignored. For multiple myeloma, overall risk was not significantly high (RR, 1.14), but there was consistent evidence of increasing risk with increasing numbers of diagnostic x-ray procedures. These data suggest that persons with leukemia and NHL undergo x-ray procedures frequently just prior to diagnosis for conditions related to the development or natural history of their disease. There was little evidence that diagnostic x-ray procedures were causally associated with leukemia or NHL. The risk for multiple myeloma, however, was increased among those patients who were frequently exposed to x-rays

    Bone disease is the most frequent complication in multiple myeloma (MM) resulting in osteolytic lesions, bone pain, hypercalcemia and renal failure. In MM bone disease the perfect balance between bone-resorbing osteoclasts (OCs) and bone-forming osteoblasts (OBs) activity is lost in favour of OCs, thus resulting in skeletal disorders. Since exosomes have been described for their functional role in cancer progression, we here investigate whether MM cell-derived exosomes may be involved in OCs ...

    Full Text Available Introduction: Although mutations of p53 are one of the most often acquired genetic changes in malignant tumors, these mutations are rare events in patients with newly diagnosed multiple myeloma (MM. Moreover, there are a few literature data about clinical significance of p53 overexpression in multiple myeloma. Objective The aim of our study was to evaluate the clinical significance of p53 immunoexpression in multiple myeloma. Method A total of 58 patients with newly diagnosed MM (26 females and 32 males, mean age 62 years were enrolled in the study. The diagnosis of MM was made according to criteria of Chronic Leukemia-Myeloma Task Force. Clinical staging was done according to Durie and Salmon classification (4 patients had disease stage I, 15 patients stage II and 39 patients stage III. The histological grade and histological stage were determined according to predominant plasma cell morphology and volume of myeloma infiltration, respectively. Standard immunohistochemical analysis with p53 antibody in B5-fixed and paraffin- embedded bone marrow specimens was used to evaluate the expression of p53 in myeloma cells. The specimens were considered positive when ≥5% of plasma cells exhibited clear nuclear positivity. Results Out of 58 patients, p53 expression was detected in 9 (15.52%. No significant correlation was found between p53 expression and clinical stage (I+II vs. III, Я2-microglobulin level (≤6 mg/L vs. >6mg/L, histological grade (I vs. II+III, histological stage (<20% vs. 21-50% vs. >50% and the extent of osteolytic lesions (≤3 vs. >3 lesions. Median survival of patients with p53 immunoreactivity in =>5% of plasma cells was 10 months, whilst median survival of patients with p53 immunoreactivity in <5% of plasma cells was 36 months. However, such difference was not significant (p=0.2. Conclusion The frequency of p53 immunoexpression in our group of newly diagnosed MM was relatively low. Although p53 immunoexpression was not

    Chromosomal abnormalities, such as 13q deletions, are emerging as important prognostic factors in multiple myeloma. Fluorescence in situ hybridization (FISH) using specific DNA probes is the technique most widely used for the determination of genomic aberrations in this disease. The utility of comparative genomic hybridization (CGH) for molecular diagnostics in plasma cell malignancies has not been systematically analysed. We investigated tumour samples of patients with multiple myeloma (n = 43) or plasma cell leukaemia (n = 3) using CGH and FISH with five DNA probes localized to chromosome bands 1p22, 6q21, 11q22-q23, 13q14 and 17p13. By CGH, the most frequent genomic changes were gains on chromosomes 1q, 9q and 11q, as well as losses on chromosomes 13q, 6q, Xp and Xq. By FISH, trisomy 11q was identified at a similar frequency to the 13q deletion (42%). Compared with FISH data, the sensitivity of CGH was 80.7% and the specificity was 97.5%. Thirty-two aberrations found by FISH were not identified by CGH, mostly as a result of the proportion of cells carrying the respective aberrations, or because of the limited spatial resolution of CGH. Our data indicate that, for clinical molecular diagnostics in multiple myeloma, FISH with a disease-specific DNA probe set is superior to CGH analysis.

    Several risk scores for disease progression in patients with smoldering multiple myeloma (SMM) have been proposed; however, all have been developed using single-center registries. To examine risk factors for time to progression (TTP) to multiple myeloma (MM) for SMM, we analyzed a nationwide population-based cohort of 321 patients with newly diagnosed SMM registered within the Danish Multiple Myeloma Registry between 2005 and 2014. Significant univariable risk factors for TTP were selected for multivariable Cox regression analyses. We found that both an M-protein ≥30 g/L and immunoparesis significantly influenced TTP (HR 2.7, 95%CI (1.5;4.7), P = 0.001, and HR 3.3, 95%CI (1.4;7.8), P = 0.002, respectively). High free light chain (FLC) ratio did not significantly influence TTP in our cohort. Therefore, our data do not support recent IMWG proposal of identifying patients with FLC ratio above 100 as having ultra high-risk of transformation to MM. Using only immunoparesis and M-protein ≥30 g/L, we created a scoring system to identify low-, intermediate-, and high-risk SMM. This first population-based study of patients with SMM confirms that an M-protein ≥30 g/L and immunoparesis remain important risk factors for progression to MM. © 2015 John Wiley & Sons A/S.

    Traditionally, the skeletal survey has been the standard modality for the detection of osteolytic bone disease in multiple myeloma. In addition to its poor sensitivity for the detection of osteolytic lesions, this modality is not able to identify extramedullary lesions and focal bone marrow involvement, nor measure response to therapy. The application of novel imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and molecular imaging such as fluorine-18 fluorodeoxyglucose positron emission tomography CT (18F-FDG PET/CT) and fluorine-18 sodium fluoride positron emission tomography CT (18F-NaF PET/CT) has the potential to overcome these limitations as well as provide prognostic information in precursor states and multiple myeloma. Also promising is the use of dynamic contrast enhanced magnetic resonance imaging (DCE MRI) to measure vascular permeability, an important feature of myelomagenesis. This review summarizes the current status and possible future role of novel imaging modalities in multiple myeloma and its precursor states. PMID:21649546

    Full Text Available Crohn's disease (CD is a chronic inflammatory bowel disease (IBD that presents with abdominal pain, weight loss, and diarrhea. Although the etiology has not been fully elucidated, both environmental and genetic causes are known to be involved. In chronic inflammatory conditions such as IBD, B lymphocytes are chronically stimulated, and they induce monoclonal expansion of plasma cells, sometimes resulting in monoclonal gammopathy of undetermined significance. Immunomodulators that are commonly used to control inflammation, such as tumor necrosis factor-α (TNF-α blockers could increase the possibility of hematologic malignancy. The pathogenesis of multiple myeloma in association with TNF-α inhibitor therapy is attributed to decreased apoptosis of plasma cell populations. Here, we describe a case of a 36-year-old male patient who was diagnosed with immunoglobulin A subtype smoldering multiple myeloma during the treatment for CD with infliximab and adalimumab. We report this case along with a review of the literature on cases of multiple myeloma that occurred in conjunction with CD.

    Solitary plasmacytoma and multiple myeloma require a differentiated radiotherapy. The irradiation for plasmacytoma with an adequate total dose (medullary 40-50 Gy or extramedullary 50-60 Gy) leads to a high degree of local control with a low rate of side effects. In cases of multiple myeloma radiotherapy will achieve effective palliation, both in terms of recalcification as well as reduction of neurological symptoms and analgesia. In terms of analgesia the rule is the higher the single dose fraction the faster the reduction of pain. As part of a conditioning treatment prior to stem cell transplantation radiotherapy contributes to the establishment of a graft versus myeloma effect (GVM). (orig.)

    Multiple myeloma is of great concern since existing therapies are unable to cure this clinical condition. Alternative therapeutic approaches are mandatory, and the use of plant extracts is considered interesting. Punica granatum and its derived products were suggested as potential anticancer agents due to the presence of bioactive compounds. Thus, polypenolic-rich extracts of the non-edible parts of P. granatum were investigated for their antiproliferative and apoptotic effects on U266 multiple myeloma cells. We demonstrated that there were dose-dependent decreases in the proliferation of U266 cells in response to P. granatum extracts. Also, exposure to the extracts triggered apoptosis with significant increases in loss of mitochondrial membrane potential in U266 cells exposed to the leaves and stem extracts, while the flower extract resulted in slight increases in loss of MMP. These results were confirmed by Annexin-V analysis. These results documented the cytotoxic and apoptotic effects of P. granatum extracts on human U266 multiple myeloma cells via disruption of mitochondrial membrane potential and increasing cell cycle arrest. The data suggest that the extracts can be envisaged in cancer chemoprevention and call for further exploration into the potential application of these plant parts.

    Full Text Available Autologous graft versus host disease (autoGVHD is a rare transplant complication with significant morbidity and mortality. It has been hypothesized that patients with multiple myeloma might be predisposed to autoGVHD through dysregulation of the immune response resulting from either their disease, the immunomodulatory agents (IMiDs used to treat it, or transplant conditioning regimen. Hematopoietic progenitor cell (HPC products were available from 8 multiple myeloma patients with biopsy-proven autoGVHD, 16 matched multiple myeloma patients who did not develop autoGVHD, and 7 healthy research donors. The data on number of transplants prior to developing autoGVHD, mobilization regimens, exposure to proteasome inhibitors, use of IMiDs, and class I human leukocyte antigen types (HLA A and B were collected. The HPC products were analyzed by flow cytometry for expression of CD3, CD4, CD8, CD25, CD56, and FoxP3. CD3+ cell number was significantly lower in autoGVHD patients compared to unaffected controls (P=0.047. On subset analysis of CD3+ cells, CD8+ cells (but not CD4+ cells were found to be significantly lower in patients with autoGVHD (P=0.038. HLA-B55 expression was significantly associated with development of autoGVHD (P=0.032. Lower percentages of CD3+ and CD8+ T-cells and HLA-B55 expression may be predisposing factors for developing autoGVHD in myeloma.

    The U.S. Food and Drug Administration (FDA) review leading to accelerated approval of carfilzomib is described. A single-arm trial enrolled 266 patients with multiple myeloma refractory to the most recent therapy who had received prior treatment with bortezomib and an immunomodulatory agent (IMID). Patients received carfilzomib by intravenous infusion over 2 to 10 minutes at a dose of 20 mg/m2 on days 1, 2, 8, 9, 15, and 16 of the 28 days of cycle 1, and at a dose of 27 mg/m2 on the same schedule in cycle 2 and subsequent cycles. The primary efficacy endpoint was overall response rate (ORR) as determined by an independent review committee using International Myeloma Working Group Uniform Response Criteria. The safety of carfilzomib was evaluated in 526 patients with multiple myeloma treated with various dosing regimens. The ORR was 23%. The median duration of response was 7.8 months. The most common adverse reactions associated with carfilzomib infusion were fatigue, anemia, nausea, thrombocytopenia, dyspnea, diarrhea, and fever. The most common serious adverse events were pneumonia, acute renal failure, fever, and congestive heart failure. Infusion reactions to carfilzomib could be reduced by pretreatment with dexamethasone and intravenous fluids. On July 20, 2012, the FDA granted accelerated approval of carfilzomib for the treatment of patients with multiple myeloma who have received at least two prior therapies including bortezomib and an IMID and who have shown disease progression while on therapy or within 60 days of completion of the last therapy. ©2013 AACR.

    The diagnosis of myeloma, a plasma dyscrasia, often results from the workup of unexplained renal disease. Persistent renal failure in myeloma is commonly caused by tubular nephropathy due to circulating immunoglobulins and free light chains. Myeloma cast nephropathy is characterized by crystalline precipitates of monoclonal light chains within distal tubules. Immunoglobulin crystallization rarely occurs intracellularly, within proximal tubular cells (light chain proximal tubulopathy) and interstitial histiocytes (crystal-storing histiocytosis). We present a case report of a rare simultaneous occurrence of light chain proximal tubulopathy, crystal-storing histiocytosis, and myeloma cast nephropathy in a patient with κ light chain multiple myeloma. A 48-years-old man presented with uremia and anemia. Laboratory examination revealed low levels of serum IgG, IgA, and IgM. Serum and urine immunofixation electrophoresis showed a free κ monoclonal band. Bone marrow aspiration and biopsy revealed hypercellularity with marked plasmacytosis. Light microscopy revealed eosinophilic cuboid- and rhomboid-shaped crystals in the cytoplasm of proximal tubular epithelial cells, diffuse large mononuclear and multinuclear cells in the interstitium, and obstructed distal tubules with cast and giant cell reaction. Immunohistochemical examination indicated intense staining for κ light chains within casts, histiocytes, and tubular epithelial cells. Electron microscopy revealed electro-dense cuboid-, rhomboid-, or needle-shaped crystalline inclusions in proximal tubular epithelial cells and interstitial histiocytes. According to these results, we confirmed that this patient with myeloma exhibited simultaneous light chain proximal tubulopathy, crystal-storing histiocytosis, and myeloma cast nephropathy, which were attributed to monoclonal κ light chains. In addition to dialysis, the patient received induction chemotherapy with a combination of bortezomib, cyclophosphamide, and

    Cell adhesion-mediated drug resistance is an important factor that influences the effects of chemotherapy in multiple myeloma. DTX3L, a ubiquitin ligase, plays a key role in cell-cycle-related process. Here, we found that the expression of DTX3L gradually increased during the proliferation of myeloma cells, which resulted in arrest of the cell cycle in the G1 phase and promoted the adherence of myeloma cells to fibronectin or bone marrow stromal cells. In addition, silencing of DTX3L improved sensitivity to chemotherapy drugs in multiple myeloma cell lines adherent to bone marrow stromal cells and increased the expression of caspase-3 and poly-adenosine diphosphate-ribose polymerase, two markers of apoptosis. Finally, we also found that DTX3L expression was regulated by focal adhesion kinase. Taken together, the results of this study show that DTX3L plays an important role in the proliferation and cell adhesion-mediated drug resistance of multiple myeloma cells and as such may play a key role in the development of multiple myeloma.

    Full Text Available The article describes a clinical case of multiple myeloma in 78-year-old man, its clinical onset was as an acute attack of gout. The patient was admitted to hospital due to the development of the first acute attack of gout. The attack was characterized by polyarthricular joint lesion of the upper and lower extremities, pronounced inflammatory reaction, insufficient response to the use of non-steroidal anti-inflammatory drugs, and a high level of hyperuricemia. The serum uric acid concentration ranged from 636 to 712 μmol/l. The study of the synovial fluid of the inflamed knee joint made it possible to reveal uric acid crystals and to confirm the diagnosis of acute gouty arthritis. Simultaneously, the patient had significant renal impairment: creatinine was 574 μmol/l, urea — 39.9 mmol/l, glomerular filtration rate according to CKD-EPI — 8 ml/min. The daily proteinuria was 1.8 g. A retrospective assessment of laboratory parameters allowed to reveal completely normal indicators of renal function 6 months ago. Considering the development of acute gouty arthritis, its polyarticular nature, persistent course, rapid involvement of new joints, high uric acid levels during an acute attack exceeding 600 μmol/l (10 mg/dL, rapid development of renal failure within 6 months until the terminal stage, it was suggested the secondary nature of gout on the background of kidney damage by another pathological process. Further clinical, laboratory and instrumental studies allowed verifying multiple myeloma with renal damage. Bence Jones protein in the urine was not detected, there was also no evidence of hyperproteinemia. However, pain in the spine, ribs and chest was the basis for carrying out an X-ray study of the bones of the skeleton. Changes in the skeleton typical for multiple myeloma have been identified. Myelogram showed a high content of plasma cells (21.1 %, electrophoresis of blood proteins showed a high M-gradient (30.42 %, and a cytochemical

    Multiple myeloma (MM) is a cancer of antibody-producing plasma cells. The pathognomonic laboratory finding is a monoclonal immunoglobulin or free light chain in the serum and/or urine in association with bone marrow infiltration by malignant plasma cells. MM develops from a premalignant condition, monoclonal gammopathy of undetermined significance (MGUS), often via an intermediate stage termed smoldering multiple myeloma (SMM), which differs from active myeloma by the absence of disease-related end-organ damage. Unlike MGUS and SMM, active MM requires therapy. Over the past 6 decades, major advancements in the care of MM patients have occurred, in particular, the introduction of novel agents (ie, proteasome inhibitors, immunomodulatory agents) and the implementation of hematopoietic stem cell transplantation in suitable candidates. The effectiveness and good tolerability of novel agents allowed for their combined use in induction, consolidation, and maintenance therapy, resulting in deeper and more sustained clinical response and extended progression-free and overall survival. Previously a rapidly lethal cancer with few therapeutic options, MM is the hematologic cancer with the most novel US Food and Drug Administration-approved drugs in the past 15 years. These advances have resulted in more frequent long-term remissions, transforming MM into a chronic illness for many patients. © 2014 American Cancer Society.

  4. The road to cure in multiple myeloma starts with smoldering disease.

    2015-04-12

    Smoldering multiple myeloma (SMM) is a heterogeneous clinical entity that defines patients in the spectrum of disease progression from monoclonal gammopathy of undetermined significance to multiple myeloma (MM). Current standard of care is observation until end organ damage occurs. In spite of this, the scientific community has begun to question whether the strategy of watchful waiting should be replaced with earlier therapeutic intervention with the ultimate goal of preventing clonal heterogeneity and end organ damage. In this review, we challenge the concept of observation as the best option of therapy in SMM. We present current data on diagnosis, prognostic factors of disease progression and studies that have been conducted to date to determine whether earlier therapeutic interventions will lead to an improvement in overall survival of patients with MM. If the recommendations of treatment of SMM were to change, the scientific body of evidence would have to overcome four major hurdles: to demonstrate that early intervention leads to prolonged survival and delay in development of end organ damage, that it does not have long-term toxicities, that it is implemented in patients with a high-likelihood of developing myeloma and that it does not lead to the outgrowth of more resistant clones. Only well-designed clinical trials will determine whether cure can be achieved with earlier interventions.

    A 68-year-old female with smoldering multiple myeloma (IgG-κ type) was admitted to the hospital owing to general fatigue, fever, and pain in the right leg. On the day following admission, she developed shock, and a blood culture revealed Streptococcus pneumoniae. She was diagnosed with septic shock and invasive pneumococcal disease (IPD). She received antibiotics and intravenous immunoglobulin and improved after several days. She had a history of recurrent IPD and had received the pneumococcal polysaccharide vaccine 23 (PPSV23) 2 years earlier. Therefore, we inquired with the National Institute of Infectious Diseases if the pneumococcal serotype isolated from her present IPD contained PPSV23. The results showed that her serotype was 19F, a serotype present in PPSV23. We administered pneumococcal conjugate vaccine 13 (PCV13) ; however, she was unable to mount high enough opsonophagocytic assay titers against some serotypes, including 19F. We think she was unable to mount effective humoral immune responses to PPSV23 or PCV13 owing to her underlying disease, smoldering myeloma. It should be considered how IPD can be effectively prevented in patients with multiple myeloma.

    Current methods for identifying neoplastic cells and discerning them from their normal counterparts are often nonspecific and biologically perturbing. Here, we show that single-cell micro-Raman spectroscopy can be used to discriminate between resistant and sensitive multiple myeloma cell lines based on their highly reproducible biomolecular spectral signatures. In order to demonstrate robustness of the proposed approach, we used two different cell lines of multiple myeloma, namely MM.1S and U266B1, and their counterparts MM.1R and U266/BTZ-R subtypes, resistant to dexamethasone and bortezomib, respectively. Then, micro-Raman spectroscopy provides an easily accurate and noninvasive method for cancer detection for both research and clinical environments. Characteristic peaks, mostly due to different DNA/RNA ratio, nucleic acids, lipids and protein concentrations, allow for discerning the sensitive and resistant subtypes. We also explored principal component analysis (PCA) for resistant cell identification and classification. Sensitive and resistant cells form distinct clusters that can be defined using just two principal components. The identification of drug-resistant cells by confocal micro-Raman spectroscopy is thus proposed as a clinical tool to assess the development of resistance to glucocorticoids and proteasome inhibitors in myeloma cells.

    Multiple myeloma (MM) is a neoplasm of plasma cells within the bone marrow. A major impact on improving survival in MM has been the use of the boronic acid-derived proteasome inhibitor bortezomib, a first-in-class selective inhibitor of the 26S proteasome. Ocular side effects of bortezomib are rare. In this report, we present 2 patients with active MM in whom persistent chalazia became a therapy-interfering complication of treatment with bortezomib. Both patients had relapsed ISS III B kappa light chain myeloma, and they were responding to treatment with bortezomib until chalazia – which caused intolerable discomfort – started. In both patients discontinuation of bortezomib was necessary for chalazia to heal, and restarting of bortezomib was associated with relapse of chalazia. PMID:26330998

    Multiple myeloma tumor cells demonstrate multiple and often complex genetic lesions as evaluated by standard cytogenetic/FISH studies. Over the past decade, specific abnormalities have been associated with standard or high-risk clinical behavior and they have become strong prognostic indicators. Further, as evidenced by recent randomized clinical trials, the choice of front-line therapy (transplant vs. no transplant, inclusion of novel drugs such as bortezomib, thalidomide, and lenalidomide) may be able to overcome the adverse effect of high-risk genetic lesions.

    Full Text Available The cooccurrence of more than one oncologic illness in a patient can present a diagnostic challenge. Here we report an unusual case of concomitant existence of multiple myeloma, breast cancer, and monoclonal B-cell lymphocytosis on initial presentation. The challenge was to accurately diagnose each disease and stage in order to maximize the therapeutic regimen to achieve cure/remission. Successful management of the patient and increased life expectancy can be achieved by multidisciplinary management and patient-oriented approach in multiple primary malignant synchronous tumors.

    Monoclonal gammopathy of unknown significance (MGUS) and smoldering multiple myeloma (SMM) are asymptomatic plasma cell dyscrasias, with a propensity to progress to symptomatic MM. In recent years there have been improvements in risk stratification models (involving molecular markers) of both disorders, which have led to better understanding of the biology and probability of progression of MGUS and SMM. In the context of numerous molecular events and heterogeneous risk of progression, developing individualized risk profiles for patients with MGUS and SMM represents an ongoing challenge that has to be addressed by prospective clinical monitoring and extensive correlative science. In this review we discuss the current standard of care of patients with MGUS and SMM, the use of risk models, including flow cytometry and free-light chain analyses, for predicting risk of progression. Emerging evidence from molecular studies on MGUS and SMM, involving cytogenetics, gene-expression profiling, and microRNA as well as molecular imaging is described. Finally, future directions for improving individualized management of MGUS and SMM patients, as well as the potential for developing early treatment strategies designed to delay and prevent development of MM are discussed.

    Multiple myeloma (MM) is a hematological malignancy that remains incurable, with relapse rates >90%. The main limiting factor for the effective use of chemotherapies in MM is the serious side effects caused by these drugs. The emphasis in cancer treatment has shifted from cytotoxic, non-specific chemotherapies to molecularly targeted and rationally designed therapies showing greater efficacy and fewer side effects. Traditional chemotherapy has shown several disadvantages such as lack of targeting capabilities, systemic toxicity, and side effects; low therapeutic index, as well as most anticancer drugs, has poor water solubility. Nanoparticle delivery systems (NPs) are capable of targeting large doses of chemotherapies into the target area while sparing healthy tissues, overcoming the limitations of traditional chemotherapy. Here, we review the current state of the art in nanoparticle-based strategies designed to treat MM. Many nanoparticle delivery systems have been studied for myeloma using non-targeted NPs (liposomes, polymeric NPs, and inorganic NPs), triggered NPs, as well as targeted NPs (VLA-4, ABC drug transporters, bone microenvironment targeting). The results in preclinical and clinical studies are promising; however, there remains much to be learned in the emerging field of nanomedicine in myeloma. © 2017 John Wiley & Sons A/S.

    The International Myeloma Working Group has proposed the Revised International Staging System (R-ISS) for risk stratification of multiple myeloma (MM) patients. There are a limited number of studies that have validated this risk model in the autologous stem cell transplant (ASCT) setting. In this retrospective study, we evaluated the applicability and value for predicting survival of the R-ISS model in 134 MM patients treated with new agents and ASCT at the Mayo Clinic in Arizona and the University Hospital of Salamanca in Spain. The patients were reclassified at diagnosis according to the R-ISS: 44 patients (33%) had stage I, 75 (56%) had stage II, and 15 (11%) had stage III. After a median follow-up of 60 months, R-ISS assessed at diagnosis was an independent predictor for overall survival (OS) after ASCT, with median OS not reached, 111 and 37 months for R-ISS I, II and III, respectively (P R-ISS II and having high-risk chromosomal abnormalities (CA) had a significant shorter median OS than those with R-ISS II without CA: 70 vs. 111 months, respectively. Therefore, this study lends further support for the R-ISS as a reliable prognostic tool for estimating survival in transplant myeloma patients and suggests the importance of high-risk CA in the R-ISS II group.

    Despite new treatment modalities, the clinical outcome in a substantial number of patients with multiple myeloma (MM) has yet to be improved. Antibody-based targeted therapies for myeloma patients could make use of the HM1.24 antigen (CD317), a surface molecule overexpressed on malignant plasma cells and efficiently internalized. Here, a novel immunotoxin, HM1.24-ETA′, is described. HM1.24-ETA′ was generated by genetic fusion of a CD317-specific single-chain Fv (scFv) antibody and a truncated variant of Pseudomonas aeruginosa exotoxin A (ETA′). HM1.24-ETA′ inhibited growth of interleukin 6 (IL-6)-dependent and -independent myeloma cell lines. Half-maximal growth inhibition was observed at concentrations as low as 0.3 nM. Target cell killing occurred via induction of apoptosis and was unaffected in co-culture experiments with bone marrow stromal cells. HM1.24-ETA′ efficiently triggered apoptosis of freshly isolated/cryopreserved cells of patients with plasma cell leukemia and MM and was active in a preclinical severe combined immunodeficiency (SCID) mouse xenograft model. Importantly, HM1.24-ETA′ was not cytotoxic against CD317-positive cells from healthy tissue (monocytes, human umbilical vein endothelial cells). These results indicate that CD317 may represent a promising target structure for specific and efficient immunotoxin therapy for patients with plasma cell tumors

    Full Text Available Multiple Myeloma (MM frequently presents with renal dysfunction apart from other manifestations. Development of renal failure in patients with MM carries a poor prognosis. Bortezo-mib is a new addition to drugs used in MM and has shown good efficacy and safety profiles. Previous trials have shown its efficacy in relapsed and refractory MM as well. Studies have also shown that bortezomib is also effective in patients with MM who present with renal failure. We report here six cases of renal failure secondary to MM treated with bortezomib. All patients had poor performance status of 3-4 on ECOG scale. Five out of six patients showed satisfactory anti-myeloma response to bortezomib. Reversal of renal failure was observed in all six patients. Adverse effects to bortezomib were mild and manageable. Reversal of renal failure persisted despite incomplete response to MM in two cases, and progression of disease in one patient. It appears that bortezomib may have an effect on the kidneys in reversal of renal failure, other than its anti-myeloma effect. In conclusion, borte-zomib appears to be an effective treatment for patients with advanced MM and renal failure irres-pective of performance status and age.

    Full Text Available Meera Mohan, Aasiya Matin, Faith E Davies Myeloma Institute, University of Arkansas for Medical Sciences, Little Rock, AR, USA Abstract: The proteasome inhibitor (PI “bortezomib” has now been in routine clinical practice for over a decade. It is now considered an important backbone therapy for all stages of the disease, and data continue to grow to support its use in newly diagnosed patients, relapsed and relapsed/refractory disease, maintenance therapy, high risk, and renal failure. Much has been learnt about the most clinically effective way of delivering therapy, with patients often benefiting more from a triplet bortezomib combination compared to a doublet combination. It is well tolerated and can be administered in the outpatient setting with manageable toxicity. The key to good results is managing side effects so that patients remain on therapy with minimal interruptions. Therefore, proactive management of peripheral neuropathy and thrombocytopenia is advised using dose delay and reduction strategies. The recent introduction of second- and third-generation PIs with different chemical and biological properties has resulted in a plethora of new clinical studies and has confirmed the ongoing role of this class of drugs in future myeloma therapy.

    The prognosis of multiple myeloma (MM) has substantially improved during last decades due to new, so-called targeted drugs--proteasome inhibitor bortezomib and immunomodulatory drugs (ImiDs), thalidomide and lenalidomide. They could be used in various combinations and/or sequentially thanks to different mechanism of action and toxicity. Both bortezomib and thalidomide are widely used in Czech republic, however, lenalidomide was approved for the treatment of MM (and MDS) at the very latest and its usage is limited due to high costs, as well. According to the results of clinical trials lenalidomide is effective in myeloma refractory to various therapy including other new drugs. First time in the Czech republic the combination of lenalidomide and dexamethasone was given in our center to 2 patients with relapsed myeloma as 7th and 10th line of therapy. Acceptable results of treatment with improved clinical status in the first patient enabled to suspend his therapeutic plasmaferesis. Disease stabilization lasting three months was observed also in the second patient.

    Full Text Available OBJECTIVES: Cytotoxic agents and steroids are used to treat lymphoid malignancies, but these compounds may exacerbate chronic viral hepatitis. For patients with multiple myeloma, the impact of preexisting hepatitis virus infection is unclear. The aim of this study is to explore the characteristics and outcomes of myeloma patients with chronic hepatitis virus infection. METHODS: From 2003 to 2008, 155 myeloma patients were examined to determine their chronic hepatitis virus infection statuses using serologic tests for the hepatitis B (HBV and C viruses (HCV. Clinical parameters and outcome variables were retrieved via a medical chart review. RESULTS: The estimated prevalences of chronic HBV and HCV infections were 11.0% (n = 17 and 9.0% (n = 14, respectively. The characteristics of patients who were hepatitis virus carriers and those who were not were similar. However, carrier patients had a higher prevalence of conventional cytogenetic abnormalities (64.3% vs. 25.0%. The cumulative incidences of grade 3-4 elevation of the level of alanine transaminase, 30.0% vs. 12.0%, and hyperbilirubinemia, 20.0% vs. 1.6%, were higher in carriers as well. In a Kaplan-Meier analysis, carrier patients had worse overall survival (median: 16.0 vs. 42.4 months. The prognostic value of carrier status was not statistically significant in the multivariate analysis, but an age of more than 65 years old, the presence of cytogenetic abnormalities, a beta-2-microglobulin level of more than 3.5 mg/L, and a serum creatinine level of more than 2 mg/ dL were independent factors associated with poor prognosis. CONCLUSION: Myeloma patients with chronic hepatitis virus infections might be a distinct subgroup, and close monitoring of hepatic adverse events should be mandatory.

    Sclerostin is a potent inhibitor of osteoblastogenesis. Interestingly, newly diagnosed multiple myeloma (MM) patients have high levels of circulating sclerostin that correlate with disease stage and fractures. However, the source and impact of sclerostin in MM remains to be defined. Our goal was to determine the role of sclerostin in the biology of MM and its bone microenvironment as well as investigate the effect of targeting sclerostin with a neutralizing antibody (scl-Ab) in MM bone disease. Here we confirm increased sclerostin levels in MM compared to precursor disease states like Monoclonal Gammopathy of Undetermined Significance (MGUS) and smoldering MM. Furthermore, we found that a humanized MM xenograft mouse model bearing human MM cells (NOD-SCID.CB17 male mice injected intravenously with 2.5 million of MM1.S-Luc-GFP cells) demonstrated significantly higher concentrations of mouse-derived sclerostin, suggesting a microenvironmental source of sclerostin. Associated with the increased sclerostin levels, activated β-catenin expression levels were lower than normal in MM mouse bone marrow. Importantly, a high affinity grade scl-Ab reversed osteolytic bone disease in this animal model. Because scl-Ab did not demonstrate significant in vitro anti-MM activity, we combined it with the proteasome inhibitor, carfilzomib. Our data demonstrated that this combination therapy significantly inhibited tumor burden and improved bone disease in our in vivo MM mouse model. In agreement with our in vivo data, sclerostin expression was noted in marrow stromal cells and osteoblasts of MM patient BM samples. Moreover, MM cells stimulated sclerostin expression in immature osteoblasts while inhibiting osteoblast differentiation in vitro. This was in part regulated by Dkk-1 secreted by MM cells and is a potential mechanism contributing to the osteoblast dysfunction noted in MM. Our data confirms the role of sclerostin as a potential therapeutic target in MM bone disease, and

    Full Text Available We present here a case of dorsal column degeneration in a female patient with multiple myeloma following exposure to bortezomib. Two days after intravenous administration of a first course of bortezomib 1 mg/m2, the patient developed rapidly-progressive numbness, pain and muscle weakness in the bilateral upper and lower limbs. Following gancyclovir treatment of subsequent cytomegalovirus viremia, the patient went on to receive a course of EPOCH (etoposide 50 mg/m2/day on days 1–4, vincristine 0.4 mg/m2/day on days 1–4, doxorubicin 10 mg/m2/day on days 1–4, cyclophosphamide 750 mg/m2/day on day 6, and prednisolone 60 mg/m2/day on days 1–6. Shortly thereafter, the patient developed bilateral Aspergillus pneumonia. Despite treatment with appropriate antifungal agents, the patient died from respiratory failure due to bilateral diffuse alveolar damage of the lungs and without recovery of severe sensory and motor neuropathy prior to her death. Post mortem examination revealed spongy degeneration of the dorsal column from the medulla oblongata to the cervical spinal cord. Bortezomib-associated peripheral neuropathy in patients with multiple myeloma has been commonly reported but appears to resolve in a majority of these patients after dose reduction or discontinuation. We believe this to be the first report of spinal cord abnormalities in a patient with multiple myeloma treated with bortezomib. Further investigation is required to ascertain the exact mechanism of this central neurotoxic effect and to identify appropriate neuroprotective strategies.

    To observe the distribution and potential distribution patterns of osteolytic and sclerotic vertebral involvement in a representative collective of multiple myeloma patients. A total of 66 consecutive patients with a diagnosis of multiple myeloma at initial diagnosis or during follow-up were examined by multidetector reduced-dose computed tomography to evaluate the distribution of bone lesions along the spine with focus on size, location, and lesion character. Confirmation of diagnosis was performed by comparison to follow-up computed tomography or magnetic resonance tomography. If >50 % of all detected malignant lesions occurred in one spinal segment, the distribution pattern was called cervical, thoracic, lumbar, or sacral, otherwise a ''mixed'' pattern was classified. Of a total number of 933 osseous spine lesions, 632 (67.7 %) were classified as malignant (98.9 % of them osteolytic) and 293 (31.5 %) as benign. The distribution pattern analysis yielded two patients (3.8 %) with a cervical, 26 (50 %) with a thoracic, 4 (7.7 %) with a lumbar, one (1.9 %) with a sacral pattern, and 19 cases (36.6 %) showed a mixed distribution pattern. Segment-wise, the mean lesion size was 6.52 ± 2.76 mm (cervical), 8.97 ± 5.43 mm (thoracic), 11.97 ± 7.11 mm (lumbar), and 17.5 ± 16.465 (sacral), whilst, related to the vertebra size, the lesion/vertebra size ratio is decreasing through the whole spine beginning from the top. Multiple myeloma bone lesions occur preferably and are larger in the thoracic and lumbar spine. Moreover, a specific distribution pattern is present in about 60 %. (orig.)

    Multiple myeloma (MM) is a malignant disorder of post-germinal center B cells, characterized by the clonal proliferation of malignant plasma cells (PCs) within the bone marrow (BM). The reciprocal and complex interactions that take place between the different compartments of BM and the MM cells result in tumor growth, angiogenesis, bone disease, and drug resistance. Given the importance of the BM microenvironment in MM pathogenesis, we investigated the possible involvement of Hypoxia-Inducible transcription Factor-1 alpha (HIF-1α) in the PCs-bone marrow stromal cells interplay. To test this hypothesis, we used EZN-2968, a 3rd generation antisense oligonucleotide against HIF-1α, to inhibit HIF-1α functions. Herein, we provide evidence that the interaction between MM cells and BM stromal cells is drastically reduced upon HIF-1α down-modulation. Notably, we showed that upon exposure to HIF-1α inhibitor, neither the incubation with IL-6 nor the co-culture with BM stromal cells were able to revert the anti-proliferative effect induced by EZN-2968. Moreover, we observed a down-modulation of cytokine-induced signaling cascades and a reduction of MM cells adhesion capability to the extracellular matrix proteins in EZN-2968-treated samples. Taken together, these results strongly support the concept that HIF-1α plays a critical role in the interactions between bone BM cells and PCs in Multiple Myeloma. - Highlights: • HIF-1α inhibition induces a mild apoptotic cell death. • Down-modulation of cytokine-induced signaling cascades upon HIF-1α inhibition. • Reduced interaction between MM cells and BMSCs upon HIF-1α down-modulation. • Reduced PCs adhesion to the extracellular matrix protein induced by EZN-2968. • HIF-1α inhibition may be an attractive therapeutic strategy for Multiple Myeloma.

These options could lead to more personalized treatment approaches, based on patient comorbidities, as the three novel agents have somewhat different toxicity profiles. Dexamethasone-based regimen is another option and questions regarding the relative efficacy of melphalan-based versus low-dose dexamethasone-based regimens will require randomized phase III trials. More intensive approaches with new drug combinations or with the incorporation of polyethylene glycolated (PEGylated liposomal doxorubicin will also require additional studies. Additionally, the important issue of maintenance treatment needs to be further investigated.

    Bisphosphonates have been used during the complete treatment of multiple myeloma for more than twenty years. They slow osteolysis and thereby contribute to the improvement of quality of life. Their long-term use, however, is related to 2 serious, usually later appearing complications: osteonecrosis of the jaw, occurring in 6-9 % of patients, and rarer atypical bone fractures. Both these complications are very difficult to heal, and all the more emphasis is therefore laid on prevention. This first of all includes discussion about the risk with the patient, followed by a dental checkup before the commencement of therapy and then repeated during its course, as well as reduced use of these drugs for a necessary period of time. However osteonecrosis of the jaw does not only develop as a consequence of bisphosphonate therapy. The complication is also caused by some new drugs (denosumab and others) used in cancer therapies. The text includes an overview of the drugs currently used in cancer treatment, which also increase the risk of appearance of osteonecrosis of the jaw. For patients with multiple myeloma, who achieve the complete or very good partial remission after chemotherapy, it is recommended to administer these drugs for more than 1 year after achieving the positive treatment response, but not longer than for 2 years. Only regarding those who do not reach the good treatment response, bisphosphonates are administered over the long term, as long as osteolytic activity of the disease lasts.Key words: atypical bone fractures - bisphosphonates - drug induced osteonecrosis of the jaw - multiple myeloma.

The patient was also noted to be hypokalemic and had low HCO3-, with possible damage to the distal tubules in the kidneys. When the treatment was begun with bortezomib/dexamethasone/elcatonin and sodium bicarbonate (NaHCO3 in normal saline (equivalent to a daily sodium dose of 200 millimoles per liter [mmol/L], the patient was in a state of poor oral fluid intake. The patient developed hypernatremia and hyperchloremia, with a peak serum sodium and chloride levels of 183 mmol/L and 153 mmol/L, respectively, at the sixth day after the start of treatment. Following the switch of the intravenous infusions from normal saline to soldem 1 and soldem 3 solutions, these high-electrolyte levels gradually returned to normal over the next 7 days. Although the patient showed disturbed consciousness (Japan Coma Scale = JCS-I-3 during the period of electrolyte abnormality, he eventually fully recovered without sequelae. In this patient, we successfully managed the severe hypernatremia/hyperchloremia, caused by the combined effects of intravenous saline burden in a state of poor oral fluid intake, during the treatment for IgG-kappa type multiple myeloma.Keywords: hypernatremia, hyperchloremia, multiple myeloma, IgG-kappa, metabolic acidosis, renal tubular damage

    Urinary excretion of vitamin A was studied in patients with multiple myeloma (MM). Eight of the 12 patients studied excreted retinol in urine; only one of them had elevated serum creatinine (115-150 micromol/L). There was a highly significant correlation between urinary retinol and serum creatinine (P urine protein (P excretion may be an early manifestation of renal dysfunction in MM patients. The effect of urinary retinol excretion on vitamin A homeostasis in MM deserves further study. Copyright 2003 Wiley-Liss, Inc.

    2009-01-05

    Bisphosphonate-associated osteonecrosis of the jaw (BON) is mainly observed in patients with multiple myeloma, and to a lesser extent in breast and prostate cancer patients receiving intravenous treatment with potent bisphosphonates. The incidence of BON increases with the duration of bisphosphonate therapy and with the potency of the used bisphosphonate. BON usually develops after tooth extraction or other oral surgery, and has proven difficult to treat. Optimal dental hygiene should be ensured prior to treatment initiation where possible, and once bisphosphonate treatment is instituted, oral surgery should be avoided if possible.

    2012-01-01

    Full Text Available Lenalidomide is a synthetic compound derived by modifying the chemical structure of thalidomide. It belongs to the second generation of immunomodulatory drugs (IMiDs and possesses pleiotropic properties. Even if lenalidomide has been shown to be active in the treatment of several hematologic malignancies, this review article is mostly focalized on its mode of action in multiple myeloma. The present paper is about the direct and indirect antitumor effects of lenalidomide on malignant plasmacells, bone marrow microenvironment, bone resorption and host’s immune response. The molecular mechanisms and targets of lenalidomide remain largely unknown, but recent evidence shows cereblon (CRBN as a possible mediator of its therapeutical effects.

    The radiosensitizing properties of gemcitabine in relation to low Linear Energy Transfer (LET) particles (Cobalt 60) and high-LET particles (alpha-RIT (213)Bi-radiolabeled CHX-DTPA-B-B4) were analyzed. Three multiple myeloma cell lines (LP1, RPMI 8226, U266) were irradiated with or without 10 nM gemcitabine 24 h prior to radiation. Gemcitabine led to radiosensitization of LP1 and U266 cells with low-LET (Radiation Enhancement Ratio: 1.55 and 1.49, respectively) but did not radiosensitize any cell line when combined with high-LET.

    2018-01-01

    We report a patient with acquired von Willebrand disease, associated with multiple myeloma. At one stage in his illness, we were unable to analyse a sample sent in a serum separator tube, due to the presence of a gel within the separated serum layer. We suggest this was due to anomalous position of the gel because of the density of the sample caused by its high total protein concentration, exacerbated by fibrin strand formation because of inhibition of appropriate fibrin clot formation secondary to clotting disorder.

    Hallmarks of cancer, including rapid growth and aneuploidy, can result in non-oncogene addiction to the proteostasis network that can be exploited clinically. The defining example is the exquisite sensitivity of multiple myeloma (MM) to 20S proteasome inhibitors, such as carfilzomib. However, MM...... patients invariably acquire resistance to these drugs. Using a next-generation shRNA platform, we found that proteostasis factors, including chaperones and stress-response regulators, controlled the response to carfilzomib. Paradoxically, 19S proteasome regulator knockdown induced resistance to carfilzomib...

    Full Text Available Background: There are few reports of glomerulonephritis (GN with crescents and a rapidly progressive course that lead to a diagnosis of a previously unsuspected B-cell dyscrasia. Case Presentation: We report a case of rapidly progressive GN: the patient showed no evidence of etiology at the time of biopsy and was diagnosed as IgA multiple myeloma (MM during investigation based on a renal biopsy. He presented diffuse proliferative and exudative GN and marked plasma cell infiltration of the kidney. Conclusion: The present case raises the possibility that proliferative GN with crescents may be a rare mode of presentation of MM.

    The effect of potential risk factors for multiple myeloma was evaluated in a case-referent study encompassing 131 cases and 431 randomized referents, all alive. Information on exposure was obtained with questionnaires mailed to the subjects. An analysis of the material by means of the Miettinen confounder score technique resulted in a few rate ratios significantly exceeding unity--namely, occupational exposure to engine exhausts, creosote, and fresh wood. In view of other studies that suggest ionizing radiation as a risk factor, it was somewhat surprising that low-level gamma radiation from background exposure was less common among the cases than the referents

    Nurses play an essential role in managing the care of patients with multiple myeloma, who require education and support to receive and adhere to optimal therapy. The International Myeloma Foundation created a Nurse Leadership Board comprised of oncology nurses from leading cancer centers and community practices. An assessment survey identified the need for specific recommendations for managing key side effects of novel antimyeloma agents. Myelosuppression, thromboembolic events, peripheral neuropathy, steroid toxicities, and gastrointestinal side effects were selected for the first consensus statements. The board developed recommendations for healthcare providers in any medical setting, including grading of side-effect toxicity and strategies for managing the side effects in general, with specific recommendations pertaining to the novel agents.

    Full Text Available Amyloidosis is a common complication of patients with monoclonal gammopathy of undetermined significance (MGUS, smoldering multiple myeloma (SMM, and multiple myeloma (MM. This proteinaceous material can be deposited intercellularly in any organ system, including the gastrointestinal (GI tract. In the GI tract, amyloidosis affects the duodenum most commonly, followed by the stomach and colorectum. Gastric amyloidosis causes symptoms of nausea, vomiting, early satiety, abdominal pain, and GI bleeding. A case of upper GI bleeding from gastric amyloidosis is presented in a patient with SMM. Esophagogastroduodenoscopy (EGD revealed a gastric mass. Endoscopic biopsies revealed amyloid deposition in the lamina propria, consistent with gastric amyloidosis. Liquid chromatography tandem mass spectrometry performed on peptides extracted from Congo red-positive microdissected areas of paraffin-embedded stomach specimens revealed a peptide profile consistent with AL- (lambda- type amyloidosis. Based on this and multiple other case reports, we recommend that patients with GI bleeding and MGUS, SMM, or MM undergo EGD and pathologic examination of endoscopic biopsies of identified lesions using Congo red stains for amyloidosis for early diagnosis and treatment.

    Full Text Available Beth Faiman, Jason Valent Department of Hematologic Oncology and Blood Disorders, Cleveland Clinic Taussig Cancer Institute, Cleveland, OH, USA Abstract: Improved understanding as to the biology of multiple myeloma (MM and the bone marrow microenvironment has led to the development of new drugs to treat MM. This explosion of new and highly effective drugs has led to dramatic advances in the management of MM and underscores the need for supportive care. Impressive and deep response rates to chemotherapy, monoclonal antibodies, and small molecule drugs provide hope of a cure or prolonged remission for the majority of individuals. For most patients, long-term, continuous therapy is often required to suppress the malignant plasma cell clone, thus requiring clinicians to become more astute in assessment, monitoring, and intervention of side effects as well as monitoring response to therapy. Appropriate diagnosis and monitoring strategies are essential to ensure that patients receive the appropriate chemotherapy and supportive therapy at relapse, and that side effects are appropriately managed to allow for continued therapy and adherence to the regimen. Multiple drugs with complex regimens are currently available with varying side effect profiles. Knowledge of the drugs used to treat MM and the common adverse events will allow for preventative strategies to mitigate adverse events and prompt intervention. The purpose of this paper is to review updates in the diagnosis and management of MM, and to provide strategies for assessment and monitoring of patients receiving chemotherapy for MM.

    Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are precursor conditions of symptomatic multiple myeloma (MM). Diagnostic principles are aimed at excluding MM requiring therapy, other conditions associated with paraproteins that may require different management, and risk stratifying patients for the purposes of tailored follow-up and investigation. The International Myeloma Working Group have recently published a revised definition of MM, which singles out a small group of patients with smoldering multiple myeloma who are at very high risk of progression and organ damage; such patients are now included under the definition of MM and recommended to start anti-myeloma treatment. Furthermore, the recently published National Institute of Health and Care Excellence guideline recommends cross-sectional imaging techniques in place of skeletal survey. These recent recommendations are discussed, and practical guidance for investigation and management are presented. Copyright © 2016 John Wiley & Sons, Ltd.

    Renal involvement in patients with multiple myeloma complicates their treatment and shortens their life-span. The main renal lesion is a tubulointerstitial transformation with fibrosis, frequently associated with cast formation in the distal nephron that results from co-precipitation of pathological immunoglobulin light chains with Tamm-Horsfall proteins. The human renal proximal tubular reabsorption of excessive light chains by endocytosis causes cellular protein overload and activates the transcription factor nuclear factor kappa B (NFkappaB). The activation of NFkappaB promotes the synthesis of inflammatory cytokines and activates signaling pathways, such as mitogen-activated protein kinases (MAPKs), extracellular signal-regulated kinase 1/2, Jun kinase, and p38 MAPK, thus promoting interstitial inflammation and fibrosis. We tested the concept that pituitary adenylate cyclase-activating polypeptide (PACAP), a member of the secretin/vasoactive intestinal peptide family, could prevent the development of cast nephropathies. PACAP38 inhibited myeloma light chain-induced proinflammatory cytokine expression with greater potency than dexamethasone, and attenuated the resulting cell damage in the renal proximal tubule epithelial cells. The results indicated that its effects are mediated through inhibition of phosphorylation of p38 MAPK and nuclear translocation of the p50 subunit of NFkappaB via both the PAC(1) and VPAC(1) receptors. PACAP was also shown to be efficacious in other common in vivo animal models for kidney hypertrophies, including streptozotocin-induced diabetic nephropathy and gentamicin-induced nephrotoxicity. Thus, our studies suggest that PACAP38 could be used as a cytoprotective agent that would be effective in the treatment of renal tubule injury in multiple myeloma and other chronic kidney diseases.

    The role of maintenance therapy in multiple myeloma is controversial. Recent studies have shown an improvement in both progression-free and overall survival for patients receiving maintenance treatment with a combination of interferon and glucocorticoids, compared with interferon alone. The role of glucocorticoids alone as maintenance therapy has not been previously addressed. We compared alternate-day, oral prednisone at 2 different dose levels (10 mg versus 50 mg) for remission maintenance among previously untreated myeloma patients following a response to induction with standard-dose vincristine, doxorubicin, and dexamethasone with prednisone (VAD-P) or VAD-P plus quinine (VAD-P/Q). There were 250 eligible patients registered on Southwest Oncology Group study 9210 and randomized to receive VAD-P or VAD-P/Q. There were 125 patients achieving at least a 25% tumor reduction following induction therapy who were randomized to either physiologic (10 mg) or pharmacologic (50 mg) doses of alternate-day, oral prednisone until disease progression. At the time of study entry, patient characteristics were similar in VAD-P and VAD-P/Q patients and in the 2 arms randomized to maintenance therapy. After a median follow-up of 53 months, there was no difference in either progression-free or overall survival between the 2 induction regimens. However, from the time of maintenance randomization, both progression-free (14 versus 5 months; P =.003) and overall survival (37 versus 26 months; P =.05) were significantly improved in patients receiving 50 mg as compared with 10 mg alternate-day prednisone. There was no difference in treatment-related adverse events between the groups. Thus, 50 mg, oral, alternate-day prednisone is effective maintenance treatment for multiple myeloma patients who achieve a response to induction chemotherapy. (Blood. 2002;99:3163-3168)

    Objectives Within a median 1.2 years after patients have an initial diagnosis with multiple myeloma, up to 61% were diagnosed with renal impairment and 50% were diagnosed with chronic kidney disease. This study estimated economic burden associated with chronic kidney disease in multiple myeloma patients in the US. Methods In this retrospective cohort study, patients ≥18 years old with ≥1 inpatient or ≥ 2 outpatient multiple myeloma diagnoses between 1 January 2008 and 31 March 2015 were identified from MarketScan® Commercial and Medicare Supplemental Databases. Chronic kidney disease patients had ≥1 diagnosis of chronic kidney disease Stages 1-5 (first chronic kidney disease diagnosis date = index date) on or after the first multiple myeloma diagnosis, and were propensity score matched 1:1 to multiple myeloma patients without chronic kidney disease, end-stage renal disease, dialysis, or other type of chronically impaired renal function. All patients had ≥six-month continuous enrollment prior to index date and were followed for ≥one month from index date until the earliest of inpatient death, end of continuous enrollment, or end of the study period (30 September 2015). The per-patient per-year healthcare resource utilization and costs were measured during follow-up. Costs were total reimbursed amount in 2016 US dollars. Results A total of 2541 multiple myeloma patients with chronic kidney disease stages 1-5 and 2541 matched controls met the study criteria and were respectively 69.3 and 69.6 years, 54.5% and 55.3% men, and had 572.2 and 533.4 mean days of follow up. Compared to controls, chronic kidney disease patients had significantly (all P chronic kidney disease, end-stage renal disease, or dialysis had $78,455 ( P chronic kidney disease in patients with multiple myeloma was estimated to be between $34,754 and $78,455 per-patient per-year.

O paciente com MM assintomático não deve receber tratamento ao diagnóstico, mas apenas quando surgirem indicações. Para o paciente sintomático (anemia, hipercalcemia, alteração da função renal, presença de lesões líticas ou plasmocitoma extramedular, aumento progressivo do componente-M no soro e/ou urina, o tratamento deverá ser rapidamente instituído. Aqueles pacientes com menos de 65-70 anos, com bom performance status, sem comorbidades e com função renal próxima do normal são potencialmente candidatos à consolidação com altas doses de quimioterapia seguidas de transplante autólogo de células-tronco hematopoéticas. Portanto, não devem utilizar drogas alquilantes para evitar prejuízos à mobilização das células-tronco. São opções: dexametasona, VAD e talidomida (com ou sem dexametasona. Os pacientes com mais de 65-70 anos, com performance status ruim, comorbidades e com função renal alterada podem receber tratamento com agentes alquilantes (por exemplo, melfalano e prednisona, com ou sem talidomida pois não serão submetidos a transplante. O principal objetivo nesses casos é atingir resposta com mínima toxicidade.The aim of this review is to evaluate the current status of first line treatment in multiple myeloma.

    Sclerostin is a potent inhibitor of osteoblastogenesis. Interestingly, newly diagnosed multiple myeloma (MM) patients have high levels of circulating sclerostin that correlate with disease stage and fractures. However, the source and impact of sclerostin in MM remains to be defined. Our goal was to determine the role of sclerostin in the biology of MM and its bone microenvironment as well as investigate the effect of targeting sclerostin with a neutralizing antibody (scl-Ab) in MM bone disease. Here we confirm increased sclerostin levels in MM compared with precursor disease states like monoclonal gammopathy of undetermined significance (MGUS) and smoldering MM. Furthermore, we found that a humanized MM xenograft mouse model bearing human MM cells (NOD-SCID.CB17 male mice injected intravenously with 2.5 million of MM1.S-Luc-GFP cells) demonstrated significantly higher concentrations of mouse-derived sclerostin, suggesting a microenvironmental source of sclerostin. Associated with the increased sclerostin levels, activated β-catenin expression levels were lower than normal in MM mouse bone marrow. Importantly, a high-affinity grade scl-Ab reversed osteolytic bone disease in this animal model. Because scl-Ab did not demonstrate significant in vitro anti-MM activity, we combined it with the proteasome inhibitor carfilzomib. Our data demonstrated that this combination therapy significantly inhibited tumor burden and improved bone disease in our in vivo MM mouse model. In agreement with our in vivo data, sclerostin expression was noted in marrow stromal cells and osteoblasts of MM patient bone marrow samples. Moreover, MM cells stimulated sclerostin expression in immature osteoblasts while inhibiting osteoblast differentiation in vitro. This was in part regulated by Dkk-1 secreted by MM cells and is a potential mechanism contributing to the osteoblast dysfunction noted in MM. Our data confirm the role of sclerostin as a potential therapeutic target in MM bone disease

    Full Text Available Multiple myeloma (myeloma multiplex (MM is a malignant non-Hodgkin’s lymphoma derived from B cell. Its essence is a malignant clone of plasma cells synthesizing growth of monoclonal immunoglobulin, which infiltrate the bone marrow, destroy the bone structure, and prevent the proper production of blood cells components. The paper presents a case of 62-year-old patient who developed symptoms in addition to neurological and haematological changes in the oral mucosa in the course of multiple myeloma. The treatment resulted in partial improvement. The authors wish to draw attention not only to nonspecificity and rarity of changes in the mouth which can meet the dentist but also to the complexity of the multidisciplinary therapy patients diagnosed with MM.

    2016-04-01

    The use of modern therapies such as thalidomide, bortezomib and lenalidomide coupled with upfront high-dose therapy and autologous stem cell transplant (ASCT) has resulted in improved survival in patients with newly diagnosed multiple myeloma (MM). However, patients with relapsed/refractory multiple myeloma (RRMM) often have poorer clinical outcomes and might benefit from novel therapeutic strategies. Emerging therapies, such as deacetylase inhibitors, monoclonal antibodies and new proteasome inhibitors, appear promising and may change the therapeutic landscape in RRMM. A limited number of studies has shown a benefit with salvage ASCT in patients with RRMM, although there remains ongoing debate about its timing and effectiveness. Improvement in transplant outcomes has re-ignited a debate on the timing and possible role for salvage ASCT and allogeneic stem cell transplant in RRMM. As the treatment options for management of patients with RRMM become increasingly complex, physicians must consider both disease- and patient-related factors in choosing the appropriate therapeutic approach, with the goal of improving efficacy while minimizing toxicity.

    Andrographolide is an active component from the extract of Andrographis paniculata [(Burm.f) Nees], a medicinal plant from the Acanthaceae family. Pharmacological studies have revealed that andrographolide possesses anti-bacterial, anti-inflammatory, anti-viral, immune regulatory and hepatoprotective properties, and is efficacious in the treatment of cardiovascular diseases, while exhibiting low toxicity and low cost. The present study aimed to determine the inhibitory effects of andrographolide on the growth of multiple myeloma (MM) cells and its possible impact on the Toll-like receptor (TLR)4/nuclear factor (NF)-κB signaling pathway. Cell proliferation was detected using an MTT assay, cellular apoptosis was measured using flow cytometry, and caspase-9/3 activation were assessed using colorimetric assay kits. Furthermore, TLR4 and NF-κB protein expression was determined by western blot analysis. The results revealed that andrographolide reduced the proliferation, while increasing cellular apoptosis and caspase-9/3 activation of MM cells, in addition to downregulating the expression of TLR4 and NF-κB protein. Of note, TLR4- or NF-κB-targeting small-interfering (si)RNA enhanced the andrographolide-induced inhibition of cell proliferation and induction of apoptosis of MM cells. The results of the present study therefore suggested that andrographolide inhibited multiple myeloma cells via the TLR4/NF-κB signaling pathway.

    Type 2 diabetes (T2D) has been suggested to be a risk factor for multiple myeloma (MM), but the relationship between the two traits is still not well understood. The aims of this study were to evaluate whether 58 genome-wide-association-studies (GWAS)-identified common variants for T2D influence...... the risk of developing MM and to determine whether predictive models built with these variants might help to predict the disease risk. We conducted a case-control study including 1420 MM patients and 1858 controls ascertained through the International Multiple Myeloma (IMMEnSE) consortium. Subjects...... genetic information (area under the curve (AUC)=0.645 vs AUC=0.629; P=4.05×10(-) (06)). A gender-stratified analysis also revealed a significant gender effect modification for ADAM30rs2641348 and NOTCH2rs10923931 variants (Pinteraction=0.001 and 0.0004, respectively).

    Description of a variant of multiple myeloma in a dog lacking the gammopathy normally associated with this type of neoplasm. A Border Collie mongrel was presented with symptoms of progressive hind-leg weakness, lethargy and tiredness, which had started to appear 6 weeks previously. Radiographic examination showed small osteolytic areas in the spinal column, but also diffuse small areas of increased opacity as well as evidence of decreased bone density in the pelvis and of both femoral necks. Moderate regenerative anaemia, hypogammopathy and hypercalcaemia were diagnosed. Computed tomography scans displayed multifocal osteolysis and bone destruction in the skull, spinal column, scapulae, proximal humeri, pelvis and femoral necks. H&E staining of the biopsies showed bone destruction and monomorphic plasmacyotid cell populations, causing infiltrative bone marrow lesions and osteolysis. In many areas neoplastic plasma cell infiltration of the bone marrow was 70% and in some areas reached 100%. The diagnosis was non-secretory multiple myeloma without apparent secretion of paraproteins into the blood.

    Previous studies demonstrated the relevance of focal lesions (FL) in whole-body magnetic resonance imaging (wb-MRI) at the initial workup of patients with smoldering multiple myeloma (SMM). The aim of this study was to assess the effects of longitudinal wb-MRIs on progression into multiple myeloma (MM). Sixty-three patients with SMM were analyzed who received at least two wb-MRIs for follow-up before progression into MM. Radiological progressive disease (MRI-PD) was defined as detection of new FL or increase in diameter of existing FL and a novel or progressive diffuse infiltration. Radiological stable disease (MRI-SD) was defined by no change compared with the prior MRI. Patients were followed-up every 3-6 months, including a serological and clinical evaluation. One Hundred and eighty-two wb-MRIs were analyzed. MRI-PD occurred in 31 patients (49%), and 25 (40%) patients developed MM. MRI-PD was highly significantly associated with progression into MM, regardless of findings at the initial MRI. In multivariate analysis, MRI-PD remained a risk factor, independent of relevant baseline parameters like serum monoclonal protein or ⩾95% aberrant plasma cells in the bone marrow. Patients with MRI-SD had no higher risk of progression, even when FL were present at the initial MRI. Therefore, MRI is suitable for the follow-up of patients with SMM.

    2011-06-01

    Monoclonal gammopathy of undetermined significance (MGUS) is defined as a serum M protein level of less than 3 g/dL, less than 10% clonal plasma cells in the bone marrow, and the absence of end-organ damage. The prevalence of MGUS is 3.2% in the white population but is approximately twice that high in the black population. MGUS may progress to multiple myeloma, AL amyloidosis, Waldenström macroglobulinemia, or lymphoma. The risk of progression is approximately 1% per year, but the risk continues even after more than 25 years of observation. Risk factors for progression include the size of the serum M protein, the type of serum M protein, the number of plasma cells in the bone marrow, and the serum free light chain ratio. Smoldering (asymptomatic) multiple myeloma (SMM) is characterized by the presence of an M protein level of 3 g/dL or higher and/or 10% or more monoclonal plasma cells in the bone marrow but no evidence of end-organ damage. The overall risk of progression to a malignant condition is 10% per year for the first 5 years, approximately 3% per year for the next 5 years, and 1% to 2% per year for the following 10 years. Patients with both MGUS and SMM must be followed up for their lifetime.

    The relationships of radium exposure to mortality from multiple myeloma, leukemia, and breast cancer were studied in three cohorts of female dial workers defined by year of first employment. Mortality was compared with that expected from US white female rates, with and without adjustment for local mortality rates. Dose-response relationships of these cancers to systemic intake of radium were determined in workers whose body burdens had been measured in vivo since 1955. Incident cases of multiple myeloma occurred in the pre-1930 cohort; however, analyses of body burdens and durations of employment suggest that external radiation was more likely to have been responsible than was internal radium. Leukemia incidence and mortality have not been elevated overall among the female dial workers, either in the pre-1930 or the post-1930 cohorts, but cases have tended to occur early and in subjects with higher body burdens. Extensive analyses of breast cancer data have uncovered several observations weighing against a causal interpretation of the association between radium and breast cancer

    To evaluate the low-dose biplanar (LDB) skeletal survey (SS) for the assessment of focal bone involvement in patients with multiple myeloma (MM) as compared with digital SS and to compare the two techniques in terms of image quality, patient comfort and radiation exposure. Fifty-six consecutive patients with newly diagnosed or first relapsed MM underwent LDB and digital SS on the same day. These were assessed by two radiologists for the detection of focal bone lesions. In the case of discordance, whole-body MR imaging was performed. Image quality, patient comfort and radiation dose were also assessed. Fifty-six patients (M:30, F:26, mean age, 62 years) with newly diagnosed (n = 21) or first relapse MM (n = 35) were enrolled. A total of 473 bone lesions in 46 patients (82 %) were detected. Out of that total, digital SS detected significantly more lesions than LDB SS (451 [95.35 %] versus 467 [98.73 %]), especially in osteopenic and obese patients. Overall patient satisfaction was greater with LDB SS (48.6 %) compared with digital SS (2.7 %). The radiation dose was significantly reduced (by a factor of 7.8) with the LDB X-ray device. Low-dose biplanar skeletal surveys cannot replace digital SS in all patients suffering from multiple myeloma. (orig.)

    Full Text Available OBJECTIVE: To determine the quality of life in patients with multiple myeloma treated with vertebroplasty. Multiple myeloma has a prevalence of 1% in all neoplastic diseases and 10% of hematological malignancies. Bone pain is the initial symptom in most cases. METHODS: A series of cases study was conducted. Patients were assessed by the Karnofsky scale to measure its functionality, the WHO analgesic scale to assess the type of analgesic and visual analog scale (VAS and the Oswestry questionnaire for pain. RESULTS: Of 24 patients, 10 were cases (vertebroplasty (41.7% and 14 were controls (conservative (58.3%, 13 (54.2% were female and 11 (45.8% male, with an average age of 60 years (SD = 12 and 63 kg of average weight (SD = 12, mean height of 1.59 cm (SD = 9 and mean body mass index of 24.8 (SD = 3.7. Survival was obtained from the time of diagnosis to death, and 2 (8.3% patients died within the first 2 years and 1 (4.2% after 3 years. CONCLUSIONS: Patients with MM who have vertebral fractures are excellent candidates to undergo vertebroplasty, because this represents a greater benefit in their quality of life, which has a direct impact on their level of functionality, giving them greater self-sufficiency and reducing their pain because of the benefits of the thermogenic effect of vertebroplasty.

    Cytogenetic evaluation at the time of diagnosis is essential for risk stratification in multiple myeloma, however little is known about the occurrence and prognostic significance of cytogenetic evolution during follow-up. We studied 989 patients with multiple myeloma, including 304 patients with at least two cytogenetic evaluations. Multivariable-adjusted regression models were used to assess the associations between the parameters of interest and cytogenetic evolution as well as overall survival. The prognostic significance of baseline cytogenetic abnormalities was most pronounced at the time of diagnosis and attenuated over time. In the patients with serial cytogenetic evaluations, the presence of t(11;14) at the time of diagnosis was associated with decreased odds of cytogenetic evolution during follow-up (odds ratio (OR)=0.22, 95% confidence interval (CI)=0.09–0.56, P=0.001), while the presence of at least one trisomy or tetrasomy was associated with increased odds (OR=2.96, 95% CI=1.37–6.42, P=0.006). The development of additional abnormalities during the 3 years following diagnosis was associated with increased subsequent mortality (hazard ratio=3.31, 95% CI=1.73–6.30, P<0.001). These findings emphasize the importance of the underlying clonal disease process for risk assessment and suggest that selected patients may benefit from repeated risk stratification. PMID:26967818

    Background The purpose of this study was to investigate the presence of punched-out lesions in craniofacial bones using three different radiographic protocols in a large cohort of patients. Material and Methods One hundred fifty-five MM patients were evaluated using panoramic and skull (frontal and lateral) radiographs, which were performed in all patients at the time of MM diagnosis. The diagnostic potential for detecting punched-out lesions was compared among the radiographic techniques. Results MM punched-out lesions were identified in 135 (87%) panoramic radiographs, 141 (91%) frontal and 144 (93%) lateral skull radiographs. Punched out-lesions were synchronously present in skull and jawbones in 129 (83.23 %) cases. The lesions were detected exclusively in skull in 18 (11.61%) cases and exclusively in jawbones in 6 (3.87%) cases. Punched out-lesion mainly affected the skull and the jawbones in a synchronous way (p<0.001) rather than separately. Conclusions All investigated radiographic techniques (panoramic, frontal and lateral skull approaches) demonstrated high detection rates for MM punched-out lesions in craniofacial bones. Panoramic radiography may aid to the radiographic protocols to identify multiple myeloma bone lesions. Key words:Multiple myeloma, osteolytic lesions, panoramic radiography. PMID:29274154

    Full Text Available Patients with multiple myeloma (MM treated with conventional chemotherapy have an average survival of approximately three years. High dose chemotherapy followed by autologous stem cell transplantation (ASCT, first introduced in the mid-1980s, is now considered the standard therapy for almost all patients with multiple myeloma, because it prolongs overall survival and disease free survival. Between November 1997 and October 2006, 122 patients with MM (58 females, 64 males, median age 51.0 years [± 7.98] range: 30–66 years were transplanted in the Department of Hematooncology and Bone Marrow Transplantation at the Medical University of Lublin: 47 patients were in complete remission or in unconfirmed complete remission, 66 patients were in partial remission, and nine had stable disease. Of these, there were 95 patients with IgG myeloma, 16 with IgA myeloma, one with IgG/IgA, one with IgM myeloma, five with non secretory type, two with solitary tumor and two with LCD myeloma. According to Durie-Salmon, 62 patients had stage III of the disease, 46 had stage II and four had stage I. Most patients (69/122 were transplanted after two or more cycles of chemotherapy, 48 patients were transplanted after one cycle of chemotherapy, one patient after surgery and rtg- -therapy and four patients had not been treated. In mobilisation procedure, the patients received a single infusion of cyclophosphamide (4–6 g/m2 or etoposide 1.6 g/m2 followed by daily administration of G-CSF until the peripheral stem cells harvest. The number of median harvest sessions was 2.0 (± 0.89 (range: 1–5. An average of 7.09 (± 33.28 × 106 CD34+ cells/kg were collected from each patient (range: 1.8–111.0 × 106/kg. Conditioning regimen consisted of high dose melphalan 60–210 mg/m2 without TBI. An average of 3.04 (± 11.59 × 106 CD34+ cells/kg were transplanted to each patient.

    Full Text Available Purpose: Novel therapy has dramatically changed the outcome of patients with myeloma. Current National Comprehensive Cancer Network guidelines give bortezomib-based combinations a central role in the management of multiple myeloma (MM. The aim of this survey is to assess the use of bortezomib for the treatment of MM by hematologists practicing in Nigeria. Materials and Methods: This is a cross-sectional observational survey. A structured, prevalidated questionnaire was self-administered to different cadres of hematologists. Data collected were analyzed using SPSS software version 21 (IBM, Chicago, IL. Results: There were 54 respondents from 24 centers across the country. The most frequently used drugs for first-line therapy were thalidomide (66.7%, dexamethasone (54.2%, and bortezomib (48%, and a combination of bortezomib, thalidomide, and dexamethasone (16.7% was the most frequently used first-line regimen. Of the 54 hematologists, 39 (72.2% had prescribed bortezomib previously; no one had used bortezomib as monotherapy. Drug unavailability (86.7% and cost (46.7% were the major reasons for those who had not prescribed bortezomib. Approximately 56.4% of responders had patients who had experienced adverse effects, of which neuropathy was the most common (86.3%. Conclusion: Bortezomib, thalidomide, and dexamethasone was the most frequently used first-line regimen to treat myelomatosis. Thalidomide and dexamethasone were the most frequently used drugs in myeloma treatment. Despite poor access to health care, coupled with the high cost and poor availability of bortezomib in our low- or middle-income country, those who prescribed bortezomib did so frequently (in more than half of their patients.

    2017-01-01

    C-X-C-motif chemokine receptor 4 (CXCR4) is a key factor for tumor growth and metastasis in several types of human cancer. We have recently reported promising first-in-man experience with CXCR4-directed endoradiotherapy (ERT) in multiple myeloma (MM). Eight heavily pretreated MM patients underwent a total of 10 ERT cycles (7 patients with 1 cycle and a single patient with 3 cycles). ERT was administered in combination with chemotherapy and autologous stem cell support. End points were occurrence and timing of adverse events, progression-free and overall survival. ERT was overall well tolerated without any unexpected acute adverse events or changes in vital signs. With absorbed tumor doses >30-70 Gy in intra- or extramedullary lesions, significant anti-myeloma activity was observed with 1 patient achieving complete remission and 5/8 partial remission. Directly after ERT major infectious complications were seen in one patient who died from sepsis 22 days after ERT, another patient with high tumor burden experienced lethal tumor lysis syndrome. Median progression-free survival was 54 days (range, 13-175), median overall survival was 223 days (range, 13-313). During follow-up (6 patients available), one patient died from infectious complications, 2/8 from disease progression, the remaining 3/8 patients are still alive. CXCR4-directed ERT was well-tolerated and exerted anti-myeloma activity even at very advanced stage MM with presence of extramedullary disease. Further assessment of this novel treatment option is highly warranted.

    Full Text Available Purpose: Multiple myeloma (MM is a clonal bone marrow disease characterized by the neoplastic transformation of differentiated postgerminal B cells. It is a heterogeneous disease both at the genetic level and in terms of clinical outcome. Immunoglobulin M (IgM MM is a rare subtype of myeloma. Similar to Waldenström macroglobulinemia (WM, patients with MM experience IgM monoclonal gammopathy; however, both diseases are distinct in terms of treatment and clinical behavior. Materials and Methods: To shed light on the presentation of IgM MM, its prognosis, and its gene expression profiling, we identified and characterized 21 patients with IgM MM from our database. Results: One of these patients presented with a rare IgM monoclonal gammopathy of undetermined significance that progressed to smoldering myeloma. The median survival of the 21 patients was 4.9 years, which was comparable to a matched group of patients with non-IgM MM with similar myeloma prognostic factors (age, gender, albumin, creatinine, anemia, lactate dehydrogenase, β2-microglobulin, cytogenetics abnormalities, but much less than the median survival reported for patients with WM (9 years. We identified a cluster of genes that differ in their expression profile between MM and WM and found that the patients with IgM MM displayed a gene expression profile most similar to patients with non-IgM MM, confirming that IgM MM is a subtype of MM that should be differentiated from WM. Conclusion: Because the prognosis of IgM MM and WM differ significantly, an accurate diagnosis is essential. Our gene expression model can assist with the differential diagnosis in controversial cases.

    Multiple myeloma (MM) is an incurable B-cell malignancy. Therefore, new targets and drugs are urgently needed to improve patient outcome. Epigenetic aberrations play a crucial role in development and progression in cancer, including MM. To target these aberrations, epigenetic modulating agents, such as DNA methyltransferase inhibitors (DNMTi) and histone deacetylase inhibitors (HDACi), are under intense investigation in solid and hematological cancers. A clinical benefit of the use of these agents as single agents and in combination regimens has been suggested based on numerous studies in pre-clinical tumor models, including MM models. The mechanisms of action are not yet fully understood but appear to involve a combination of true epigenetic changes and cytotoxic actions. In addition, the interactions with the BM niche are also affected by epigenetic modulating agents that will further determine the in vivo efficacy and thus patient outcome. A better understanding of the molecular events underlying the anti-tumor activity of the epigenetic drugs will lead to more rational drug combinations. This review focuses on the involvement of epigenetic changes in MM pathogenesis and how the use of DNMTi and HDACi affect the myeloma tumor itself and its interactions with the microenvironment.

    Multiple myeloma (MM) is characterized by a monoclonal plasma cell population in the bone marrow. Lytic lesions occur in up to 90 % of patients. For many years, whole-body X-ray (WBX) was the method of choice for detecting skeleton abnormalities. However, the value of WBX in relapsing disease is limited because lesions persist post-treatment, which restricts the capacity to distinguish between old, inactive skeletal lesions and new, active ones. Therefore, alternative techniques are necessary to visualize disease activity. Modern imaging techniques such as magnetic resonance imaging, positron emission tomography and computed tomography offer superior detection of myeloma bone disease and extramedullary manifestations. In particular, the properties of nuclear imaging enable the identification of disease activity by directly targeting the specific cellular properties of malignant plasma cells. In this review, an overview is provided of the effectiveness of radiopharmaceuticals that target metabolism, surface receptors and angiogenesis. The available literature data for commonly used nuclear imaging tracers, the promising first results of new tracers, and our pilot work indicate that a number of these radiopharmaceutical applications can be used effectively for staging and response monitoring of relapsing MM patients. Moreover, some tracers can potentially be used for radio immunotherapy. (orig.)

    Full Text Available Abstract Background Multiple Myeloma (MM is a B cell neoplasm characterized by the clonal proliferation of plasma cells. Skeletal complications are found in up to 80% of myeloma patients at presentation and are major cause of morbidity. Methods 49 patients were enrolled with MM admitted to Black Sea Technical University Hospital between 2002–2005. Pathologic fractures (PFs were determined and the patients with or without PF were followed up minumum 3 years for survival analysis. Results PF was observed in 24 patients (49% and not observed in 25 patients (51%. The risk of death was increased in the patients with PF compared with patients who had no fractures. While overall survival was 17.6 months in the patients with PFs, it was 57.3 months in the patients with no PFs. Conclusion These findings suggest that PFs may induce reduced survival and increased mortality in the MM patients, however, larger sample size is essential to draw clearer conclusions added to these data.
