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...

Translocation (11;14) on interphase FISH in plasma cells is regarded as a standard risk prognostic marker in multiple myeloma (MM) based on studies conducted before introduction of current therapies. We identified 365 patients with t(11;14), and 730 matched controls:132 patients with non-(11;14) translocations and 598 with no chromosomal translocation. The median progression-free survival (PFS) for the three groups were 23.0 (95% CI, 20.8-27.6), 19.0 (95% CI, 15.8-22.7) and 28.3 (95% CI, 25.7-30.6) months respectively [P<0...

Multiple myeloma (MM) patients with t(4;14) is a heterogeneous group. Prognostic tools capable of predicting the outcome of patients are currently lacking. The MM SET domain (MMSET) protein is universally overexpressed and has been suggested to have an important tumorigenic role. This study analyzed whether the overexpression of full-length (MB4-1) or truncated forms (MB4-2 and MB4-3) of MMSET influence the prognosis of t(4;14)pos MM patients. A total of 53 symptomatic t(4;14)pos MM patients were retrospectively analyzed...

Robust establishment of survival in multiple myeloma (MM) and its relationship to recurrent genetic aberrations is required as outcomes are variable despite apparent similar staging. We assayed copy number alterations (CNA) and translocations in 1036 patients from the NCRI Myeloma XI trial and linked these to overall survival (OS) and progression-free survival. Through a meta-anlysis of these data with data from MRC Myeloma IX trial, totalling 1905 newly diagnosed MM patients (NDMM), we confirm the association of t(4;14), t(14;16), t(14;20), del(17p) and gain(1q21) with poor prognosis with hazard ratios (HRs) for OS of 1...

Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant precursor of multiple myeloma with a 1% risk of progression per year. Although targeted analyses have shown the presence of specific genetic abnormalities such as IGH translocations, RB1 deletion, 1q gain, hyperdiploidy or RAS genes mutations, little is known about the molecular mechanism of malignant transformation. We have performed whole exome sequencing together with CGH+SNP array analysis in 33 flow-cytometry separated abnormal plasma cell samples from MGUS patients to describe somatic gene mutations and chromosome changes at the genome-wide level...

Novel agents have increased survival of multiple myeloma (MM) patients, however high-risk and relapsed/refractory patients remain challenging to treat and their outcome is poor. To identify novel therapies and aid treatment selection for MM, we assessed the ex vivo sensitivity of 50 MM patient samples to 308 approved and investigational drugs. With the results we i) classified patients based on their ex vivo drug response profile; ii) identified and matched potential drug candidates to recurrent cytogenetic alterations; and iii) correlated ex vivo drug sensitivity to patient outcome...

In our previous studies, we identified 12 multiple myeloma (MM)-associated antigens by serological analysis of tumor-associated antigens with a recombinant cDNA expression library (SEREX) on MM. MM-associated antigen-8 (MMSA-8) was one of the new antigens identified. We determined the 3'- and 5'-ends of MMSA-8 using SMART-rapid amplification of cDNA ends (RACE) and then cloned its full-length cDNA in the U266 cell line. The full cDNA sequence revealed that MMSA-8 is RPS27A-related transcript variant 1 that is specifically associated with MM...

Programmed death 1 (PD-1) receptor and its ligand (PD-L1) facilitate immune evasion in multiple myeloma (MM). We hypothesized that pembrolizumab, PD-1-antibody, can enhance anti-myeloma cellular immunity generated by pomalidomide leading to improved clinical responses. In this single-center, phase II study, 48 patients with relapsed/refractory MM (RRMM) received 28-days cycles of pembrolizumab, 200 mg intravenously every 2 weeks, pomalidomide 4 mg daily for 21 days and dexamethasone 40 mg weekly. Patients had a median of 3 (range: 2-5) lines of therapy, median age 64 (range: 35-83) years and had received both immune modulatory agent and proteasome inhibitor; (35 [73%] of 48) were refractory to both; (31 [70%]) had received an autologous transplant and (30 [62%]) had high-risk cytogenetics...

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...

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...
