Abstract Multiple myeloma (MM) is a cancer of plasma cells with complex molecular characteristics that evolves from monoclonal gammopathy of undetermined significance, a highly prevalent premalignant condition. MM is the second most frequent hematologic cancer in the United States, and it remains incurable, thereby highlighting the need for new therapeutic approaches, particularly those targeting common molecular pathways involved in disease progression and maintenance, shared across different MM subtypes. Here we report that Wnt/β-catenin is one such pathway. We document the involvement of β-catenin in cell-cycle regulation, proliferation, and invasion contributing to enhanced proliferative and metastatic properties of MM. The pleiotropic effects of β-catenin in MM correlate with its transcriptional function, and we demonstrate regulation of a novel target gene, Aurora kinase A, implicating β-catenin in G2/M regulation. β-catenin and Aurora kinase A are present in most MM but not in normal plasma cells and are expressed in a pattern that parallels progression from monoclonal gammopathy of undetermined significance to MM. Our data provide evidence for a novel functional link between β-catenin and Aurora kinase A, underscoring a critical role of these pathways in MM disease progression.

Multiple myeloma represents 1.4% of all new patients with cancer and will result in an estimated 11,090 deaths in 2014. It is twice as common in black men as in white men and 2.5 times more common in black women than in white women. Myeloma is the 14th most common cause of cancer in the United States, with a median age at diagnosis of 69 years. Multiple myeloma is defined by the presence of a clonal growth of plasma cells, usually in the bone marrow, but patients may also present with extramedullary disease. Anemia and bone disease are common in patients with multiple myeloma. Multiple myeloma cells display multiple genetic abnormalities, with no one specific genetic lesion common to a majority of patients. This module describes the immunologic profile of multiple myeloma and its diagnosis, monoclonal gammopathy of undetermined significance, smoldering multiple myeloma, plasmacytoma, plasma cell leukemia, the clinical presentation of multiple myeloma bone disease, anemia, renal impairment, hypercalcemia, and neurologic symptoms associated with multiple myeloma. Therapy for transplantation-eligible and non–transplantation-eligible patients, maintenance treatment for multiple myeloma, Waldenström macroglobulinemia, and amyloidosis are also discussed. Tables outline the risk of monoclonal gammopathy of undetermined significance evolution, the myeloma staging system, recommended diagnostic testing and uniform response criteria for myeloma, and commonly used regimens in the treatment of myeloma. Figures include a magnetic resonance image showing multiple plasmacytomas, tibial lytic lesion from myeloma, calvarial lytic lesions, a positron emission tomographic scan in a myeloma patient, and hyperviscosity causing retinal hemorrhages. This review contains 5 highly rendered figures, 5 tables, and 149 references.

PD-L1 expressed on tumor cells contributes to disease progression with evasion from tumor immunity. Plasma cells from multiple myeloma (MM) patients expressed higher levels of PD-L1 compared with healthy volunteers and monoclonal gammopathy of undetermined significance (MGUS) patients, and its expression is significantly upregulated in relapsed/refractory patients. Furthermore, high PD-L1 expression is induced by the myeloma microenvironment and PD-L1+ patients with MGUS and asymptomatic MM tend to show disease progression. PD-L1 expression on myeloma cells was associated with more proliferative potential and resistance to antimyeloma agents because of activation of the Akt pathway through PD-1-bound PD-L1 in MM cells. Those data suggest that PD-L1 plays a crucial role in the disease progression of MM.

Abstract We investigated whether interleukin-1β (IL-1β) is differentially expressed in plasma cells from monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM) patients because IL-1β appears to play a major role in the development of lytic bone lesions, the major clinical feature distinguishing MGUS from myeloma. In situ hybridization (ISH) for IL-1β was performed using bone marrow aspirates from 51 MM, 7 smoldering MM, 21 MGUS, and 5 normal control samples. Using the ISH technique IL-1β mRNA was detectable in the plasma cells from 49 of 51 patients with active myeloma and 7 of 7 patients with smoldering myeloma. In contrast, 5 of 21 patients with MGUS and 0 of 5 normal controls had detectable IL-1β message. Bone lesions were present in 40 of the 51 MM patients analyzed, and all 40 patients had IL-1β mRNA by ISH. These results show that greater than 95% of MM patients but less than 25% of MGUS patients are positive for IL-1β production. In the future, continued follow-up of IL-1β positive and negative MGUS patients should determine whether aberrant expression of plasma cell IL-1β is predictive of those MGUS patients that will eventually progress to active myeloma.

Abstract Abstract 4876 Background Recent studies have found obesity to be associated with a 1.5- to 2-fold elevated risk of developing multiple myeloma. This is of particular interest given that elevated levels of the pro-inflammatory cytokine interleukin (IL)-6 have been found in obese persons, and, at the same time, IL-6 has well-known proliferative and anti-apoptotic effects on monoclonal plasma-cells. Also insulin-like growth factors (IGFs) have been proposed to play a role since obesity often causes insulin resistance, which in turn modulates the bioavailability of IGF-1 Similar to IL-6, prior studies have found IGF-1 to have both growth and survival effects on monoclonal plasma-cells. Based on these facts, we have speculated that obesity might increase the risk of the multiple myeloma precursor monoclonal gammopathy of undetermined significance (MGUS), or, alternatively, that obesity may increase the risk for transformation from MGUS to multiple myeloma. We conducted the first large screening study designed to assess the association between obesity and MGUS among almost 2,000 African-American and Caucasian women. Methods We included 1000 African-American and 996 Caucasian women (age 40-79, median 48 years) from the Southern Community Cohort Study to assess MGUS risk in relation to obesity. Per our sampling strategy, about 50% of the participants were obese. Medical record-abstracted weight and height (measured on the day of study enrollment) and self-reported values had very high concordance (Pearson correlation >0.95). Serum samples from all subjects were analyzed by electrophoresis performed on agarose gel; samples with a discrete or localized band were subjected to immunofixation. Using logistic regression models, we estimated odds ratios (ORs) as measures of risk. Results Among all study participants, 39 (3.9%) African-Americans and 21 (2.1%) Caucasians were found to have MGUS, yielding a 1.9-fold (95%CI 1.1-2.3; p=0.021) higher risk of MGUS among African-Americans (vs. Caucasians). On multivariate analysis, we found obesity (OR=1.8, 95%CI 1.03-3.1; p=0.039), African-American race (OR=1.8, 95%CI 1.04-3.1; p=0.037), and increasing age (quartiles: ≥55 vs. <43 years) (OR=2.5, 95%CI 1.1-5.7; p=0.028) to be independently associated with an excess risk of MGUS. Another interesting finding was that the distribution of the monoclonal immunoglobulin isotype usage among African-American and Caucasian women was significantly different (p=0.007). Their respective rates were: IgG in 79.5% and 71.3 %; IgA in 7.7% and 0%; IgM in 7.7% and 19%; biclonal in 5.1% and 4.7%; and triclonal in 0% and 4.7%. The distribution of serum light-chain types between the two races was also significantly different (P=0.003, chi-square test): kappa in 53.8% and 47.6%; lambda in 43.6% and 42.8%; biclonal 2.6% and 4.7%; and triclonal in 0% and 4.7%. Conclusions Our finding that MGUS is twice as common among obese (vs. non-obese) women, and independent of race, supports the hypothesis that obesity is etiologically linked to myelomagenesis and may have public health impact. The observed 2-fold excess of MGUS among African-Americans (vs. Caucasians) of similar socio-economic status, coupled with other recent studies supports a role for susceptibility genes as the cause for racial disparity in the prevalence of MGUS. Disclosures No relevant conflicts of interest to declare.

Abstract The age-adjusted incidence of multiple myeloma (MM) is 2-fold higher in African Americans than in whites. A few small studies have reported a higher prevalence of monoclonal gammopathy of undetermined significance (MGUS) in African Americans versus whites. Etiologic factors for MGUS and determinants for transformation of MGUS to MM are unknown. We quantified the prevalence of MGUS and subsequent risk of MM among 4 million African American and white male veterans admitted to Veterans Affairs (VA) hospitals. The age-adjusted prevalence ratio of MGUS in African Americans compared with whites was 3.0 (2.7-3.3 95% confidence interval). Among 2046 MGUS cases, the estimated cumulative risk of MM during the first 10 years of follow-up was similar (P = .37) for African Americans (17%) and whites (15%). In the largest study to date, we suggest that the excess risk of MM in African Americans results from an increase in risk of MGUS rather than an increased risk of progression from MGUS to MM.

The blood of most patients with active multiple myeloma (MM) contains cells related to the bone marrow tumor. However, identifying clonal cells in the blood of patients with monoclonal gammopathy of undetermined significance (MGUS) has been difficult. In this study, we analyzed blood mononuclear cells (BMNCs) from 16 patients with MGUS, 2 with amyloidosis, 8 with smoldering MM (SMM), 2 with indolent MM (IMM), and 15 with active MM using three different methods to detect and quantitate clonal cells, ie, immunofluorescence microscopy (IM) for monoclonal plasma cells, three-color flow cytometry (FC) for CD38(+)CD45- CD45(dim) cells, and the allele-specific oligonucleotide polymerase chain reaction (ASO-PCR). Using ASO-PCR, we were able to detect clonal cells in the blood in 13 of 16 patients with MGUS, 2 of 2 with amyloid, 6 of 8 with SMM, 2 of 2 with IMM, and 13 of 15 with MM. In 9 of the 13 patients with MGUS with blood involvement, the number of clonal cells was very small ( < 0.04% of the BMNCs). The median percentage of clonal cells as determined by ASO-PCR was 0.02 for MGUS, 0.02 for SMM, and 0.24 for MM. Clonal plasma cells or CD38+CD45- CD45(dim) cells were identified by IM or FC in 6 of 16 MGUS patients, 4 of 8 with SMM, and 11 of 15 with MM. In all cases in which IM or FC detected clonal cells, the ASO-PCR was positive. This study shows that, by using ASO-PCR, clonal cells can be found at very low levels in the blood in most patients with MGUS. However, the number of clonal cells in the blood of MGUS patients is less than those with overt MM (P = .006). In contrast to MGUS, patients with active MM are more likely to have identifiable clonal circulating plasma cells (P = .05).

Multiple myeloma is a tumor of plasma cells, one of the most common malignant blood diseases. It is preceded by a stage called monoclonal gammopathy of undetermined significance, from which true multiple myeloma develops in only a small percentage of cases. It was assumed that this process is associated with the accumulation of genetic mutations, but in recent years there is increasing evidence that the bone marrow microenvironment plays a key role in progression and that it can become a target for therapy that prevents the myeloma development. The review considers the role of mesenchymal stem cells, immune system cells, endotheliocytes, fibroblasts, adipocytes, osteoclasts and osteoblasts in multiple myeloma progression, as well as the impact of the sympathetic nervous system and microbiome composition.
