Solitary plasmacytoma (SP) is an uncommon, indolent tumor of plasma cell neoplasms that presents as a mass lesion in extramedullary sites. Evidence of Epstein-Barr virus (EBV) infection is frequently associated with various lymphatic and hematopoietic malignancies but is relatively rare in SP. Moreover, it is essential to distinguish EBV-positive plasmacytoma from plasmablastic lymphoma. In this study, we found 4 EBV-encoded RNA (EBER)-positive patients among 46 consecutive immunocompetent patients of SP and compared the clinicopathologic features of these patients with those of the EBER-negative cohort...

Autologous hematopoietic stem cell transplantation (auto-HSCT) has improved survival in patients with multiple myeloma (MM) and is increasingly used in elderly patients. The aim of this study was to characterize and compare in-hospital complications and mortality after auto-HSCT in younger (< age 65) versus elderly (> age 65) MM patients utilizing the Nationwide Inpatient Sample. Over a 3-year period (2008 to 2010), 2209 patients with MM were admitted to US hospitals for auto-HSCT. The median age was 59 years, with 1650 patients (74...

BACKGROUND & OBJECTIVES: Multiple myeloma (MM) is a plasma cell malignancy characterized by cytogenetic heterogeneity. In comparison with conventional karyotyping, fluorescence in situ hybridization (FISH) can efficiently detect various genetic changes in non-cycling plasma cells in 50-90 per cent of MM cases. The present study was undertaken in MM patients to evaluate the frequency and clinico-pathological significance of various cytogenetic abnormalities in the Indian population. METHODS: Interphase FISH was applied on purified plasma cells of 475 patients with MM using specific probes...

On November 30, 2015, the U.S. Food and Drug Administration (FDA) approved elotuzumab (Empliciti, Bristol-Myers Squibb) in combination with lenalidomide and dexamethasone for treatment of patients with multiple myeloma who received one to three prior therapies. FDA approval was based primarily on results of a phase 3, randomized, open-label, multicenter trial, CA204004, that evaluated elotuzumab in combination with lenalidomide and dexamethasone (E-Ld), compared with lenalidomide and dexamethasone (Ld) alone, in patients with relapsed or refractory multiple myeloma...

Background and Objective: Haematopoietic stem cell transplant is a potentially curative treatment option in various benign and malignant haematological diseases. Patients undergoing stem cell transplant procedure require blood transfusion on a daily basis. Currently, there is paucity of data from developing countries on transfusion practices. This audit was undertaken to determine the consumption of packed red blood cells (PRBCs) transfusion in the bone marrow transplant unit of the Aga Khan University Hospital...

Overexpression of the multiple myeloma set domain (MMSET) Wolf-Hirschhorn syndrome candidate 1 gene, which contains an orphan box H/ACA class small nucleolar RNA, ACA11, in an intron, is associated with several cancer types, including multiple myeloma (MM). ACA11 and MMSET are overexpressed cotranscriptionally as a result of the t(4;14) chromosomal translocation in a subset of patients with MM. RNA sequencing of CD138(+) tumor cells from t(4;14)-positive and -negative MM patient bone marrow samples revealed an enhanced oxidative phosphorylation mRNA signature...

The impact of depth of response and minimal residual disease (MRD) status on survival is not well defined in multiple myeloma (MM) with high-risk (HR) cytogenetics because of the low representation of such patients in clinical trials. We have evaluated the impact of post-transplant stringent complete response (sCR) and MRD status on progression-free survival (PFS) and overall survival (OS) in 185 consecutive MM patients with HR cytogenetics by fluorescence in situ hybridization undergoing upfront autologous stem cell transplantation between 2007 and 2015 in our institution...

Dysregulated oncogenic serine/threonine kinases play a pathological role in diverse forms of malignancies, including multiple myeloma (MM), and thus represent potential therapeutic targets. Here, we evaluated the biological and functional role of p21-activated kinase 4 (PAK4), and its potential as a new target in MM for clinical applications. PAK4 promoted MM cell growth and survival via activation of MM survival signaling pathways, including the MEK-ERK pathway. Furthermore, treatment with orally bioavailable PAK4 allosteric modulator (KPT-9274) significantly impacted MM cell growth and survival in a large panel of MM cell lines and primary MM cells alone and in the presence of bone marrow microenvironment...

The study aimed to assess prognostic significance of del(13q14), del(17p13), t(4;14)(p16;q32), and amp(1q21) in newly diagnosed myeloma patients treated mostly with thalidomide-based therapies. All genetic abnormalities except del(13q14) were independent prognostic factors associated with shortened progression-free survival (PFS) and overall survival (OS). Patients with no abnormalities, one abnormality, and ≥2 abnormalities had a median PFS of 41.8, 17.0, and 10.0 months, respectively; a median OS was not reached, 48...

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

BACKGROUND: Autologous hematopoietic stem cell transplantation is considered the standard of care for younger patients with multiple myeloma. Several mobilization regimens are currently used, most commonly growth factors alone or in combination with chemotherapy. The aim of our study was to investigate the differences in lymphocyte subpopulation counts between three different mobilization regimens on collection day, in the leukapheresis product and on day 15 after autologous hematopoietic stem cell transplantation...

Comprehensive recommendations for maintenance therapy after autologous stem cell transplantation (ASCT) for patients with multiple myeloma (MM) have yet to be defined. Bortezomib has been utilized as maintenance therapy after ASCT, but data attesting to the safety and efficacy of this agent compared with lenalidomide in the post-ASCT setting are limited. Therefore, we retrospectively analyzed the outcomes of 102 patients with MM who received maintenance therapy with bortezomib after ASCT at Duke University's adult bone marrow transplant clinic between 2005 and 2015...

Multiple myeloma (MM) patients with the t(14;16) translocation have a poor prognosis, and unlike other molecular subgroups, their outcome has not improved with the introduction of bortezomib (Bzb). The mechanism underlying innate resistance of MM to Bzb is unknown. In the present study, we have investigated how MAF overexpression impacts resistance to proteasome inhibitor (PI) therapy (Bzb and carfilzomib). High levels of MAF protein were found in t(14;16) cell lines; cell lines from the t(4;14) subgroup had intermediate levels, whereas cell lines from the other subgroups had low levels...

The Revised International Staging System (R-ISS) was recently introduced in order to improve risk stratification over that provided by the widely used standard International Staging System. In addition to the parameters of the standard system, the R-ISS incorporates the presence of chromosomal abnormalities detected by interphase fluorescence in situ hybridization [t(4;14), t(14;16) and del17p] and elevated serum lactate dehydrogenase. The R-ISS was formulated on the basis of a large dataset of selected patients who had participated in clinical trials and has not been validated in an independent cohort of unselected patients...

In the present study, the case of a 41-year-old man with immunoglobulin (Ig)M multiple myeloma (MM) that presented with an unusually non-aggressive clinical course who has survived for >9 years to date, is presented. Initial diagnosis of symptomatic MM was established according to the International Myeloma Working Group consensus statement and guidelines. Due to the mild symptoms, no therapy was administered and the patient was closely followed up. Eight years after initial diagnosis, clinical, morphological and genetic progression occurred with the development of hypercalcemia, progressively deteriorating polyneuropathy, clonal expansion of plasma cells up to 50% of hematopoietic cells and demonstration of the typical t(11;14) translocation (Ig heavy chain locus rearrangement)...

Multiple myeloma (MM) is a genetically complex disease. The past few years have seen an evolution in cancer research with the emergence of next-generation sequencing (NGS), enabling high throughput sequencing of tumors-including whole exome, whole genome, RNA, and single-cell sequencing as well as genome-wide association study (GWAS). A few inherited variants have been described, counting for some cases of familial disease. Hierarchically, primary events in MM can be divided into hyperdiploid (HDR) and nonhyperdiploid subtypes...

Autologous transplantation is controversial for older patients with multiple myeloma. The role of age-adjusted high-dose melphalan and the impact of induction chemotherapy cycles is still unclear. A total of 434 patients aged 60-70 years were randomly assigned to 4 cycles of standard anthracycline-based induction chemotherapy or no induction. For all patients, double autologous transplantation after melphalan 140 mg/m(2) (MEL140) was planned. The primary end point was progression-free survival. Of 420 eligible patients, 85% received a first transplant and 69% completed double transplantation...
