Abstract Abstract 1920 The biologic mechanisms involved in the pathogenesis of multiple myeloma (MM)-induced osteolytic bone disease are poorly understood. Physiological interactions between the serotoninergic and skeletal systems have been implicated by clinical observations. Brainstem-derived serotonin positively regulates bone mass following binding to 5-HT2C receptors on ventromedial hypothalamic neurons. This is opposed by platelet-derived serotonin that induces bone lysis and osteoclast activation. Moreover, the serotonin transporter SLCA6A4 is universally present among the malignant B cell clones. We examined serotonin dysregulation in two sample types from MM patients: peripheral blood and bone marrow. In the blood we measured by ELISA the ratio of serotonin in serum compared to platelets in patients with MM (n=10), MGUS (n=10) or healthy controls (n=5). We found higher levels of serotonin in platelets for the MM patients compared to the MGUS & healthy controls (p=0.017). Concomitantly there was less serotonin in the serum of MM patients compared to compared to the MGUS & healthy (p=0.002). This implies an imbalance in the compartmentalization of serotonin associated with presence of MM bone disease. Our multiplexed protein kinase signal pathway mapping technology, reverse phase protein microarrays (RPMA), was applied to bone marrow samples for quantifying post-translational modifications (e.g. phosphorylation, cleavage, acetylation) and/or total cell signaling kinase levels. Using reverse-phase protein microarray (RPMA) we retrospectively measured bone remodeling signal pathway perturbations in 15 bone marrow core biopsies from patients diagnosed with MM, at different clinical stages, and correlated this with the presence of MM-related bone disease (documented by scan or MRI). Bone marrow core biopsies exhibited significant elevation of cellular Serotonin, RANK, MMP-11, TNFα, TNF-R1, and Ezrin Tyr353 in MM with active bone disease (n=9) compared to patients without bone disease (n=6) (respectively p=0.031, p=0.038, p=0.0082, p=0.0221, p=0.01, p=0.028). To further evaluate the serotonin dysregulation in bone marrow cells, we measured serotonin bound to plasma cells (CD138+) compared to CD138- cells in bone marrow aspirates (n=21). Bone marrow aspirate were collected from patients undergoing standard of care hematological work up for multiple myeloma at any stage or treatment course. Patients with symptomatic myeloma (defined as presence of at least one of CRAB symptom) had lower serotonin levels in the CD138- bone microenvironment cells compared to non-symptomatic patients (p=0.0235). Plasma cells (CD138+) exhibited larger amounts of serotonin compared CD138- bone microenvironment cells (p=0.016). Taken together, our data show a dysregulation of serotonin in MM suggesting an altered distribution of serotonin in blood and bone marrow. This provides potential insights into diagnosis, prognosis, and/or treatment. Disclosures: No relevant conflicts of interest to declare.

Osteolytic Bone Disease

Abstract Multiple myeloma (MM) is a fatal hematologic malignancy associated with clonal expansion of malignant plasma cells within the bone marrow and the development of a destructive osteolytic bone disease. The principal cellular mechanisms involved in the development of myeloma bone disease are an increase in osteoclastic bone resorption, and a reduction in bone formation. Myeloma cells (MMC) are found in close association with sites of active bone resorption, and the interactions between myeloma cells and other cells within the specialized bone marrow microenvironment are essential, both for tumor growth and the development of myeloma bone disease. In order to investigate the gene expression profile (GEP) of osteoclastic cells, we compare GEP of osteoclastic cells (7 samples) with normal B cells (7 samples), normal bone marrow plasma cells (7 samples), bone marrow stromal cells (5 samples), bone marrow CD3 cells (5 samples), CD14 cells (7 samples), CD15 cells (7 samples), CD34 cells (7 samples) and primary MMC (123 samples). Using SAM analysis, a set of 552 genes was overexpressed in osteoclasts compared to others cell subpopulations with a FDR ≤ 1% and a ratio ≥ 2. Osteoclasts specifically overexpressed genes coding for chemokines (CCL2, CCL7, CCL8, CCL13, CCL18, CXCL5 and CCL23) and MMC growth factors (IGF-1, APRIL and IL-10). Anti- IGF-1 receptor and TACI-Fc inhibit MMC growth induced by osteoclasts. Among the chemokines overexpressed by osteoclasts, the majority of them have a common receptor: CCR2 expressed by MMC. Anti-CCR2 MoAb inhibits migration of the CCR2+ HMCL in response to osteoclasts. Expression data of purified MMC were analyzed by supervised clustering of group with higher (CCR2high) versus lower (CCR2low) CCR2 expression level. Patients in the CCR2high group are characterized by a higher bone disease. A set of 176 genes was differentially expressed between CCR2high and CCR2low MMC. CCR2high displayed a gene signature linked to the dependency of MMC on the interactions with the BM osteoclastic subpopulation and the osteoclastic bone resorption. Taken together, our findings suggest addition of chemokine antagonists to current treatment regimens for MM should result in better therapeutic responses because of the loss of both the protective effect of the bone marrow environment on the MMC and the osteoclastic cells activity.

Our case demonstrates severe bone disease in primary AL-amyloidosis without concomitant multiple myeloma. A 30-year-old man had spontaneous vertebral fracture Th8. A computed tomography scan suggested multiple foci of lesions in all the bones. In bone marrow and resected rib werent detected any tumor cells. After 15 years from the beginning of the disease, nephrotic syndrome developed. Based on the kidney biopsy, AL-amyloidosis was confirmed. Amyloid was also detected in the bowel and bone marrow. On the indirect signs (thickening of the interventricular septum 16 mm and increased NT-proBNP 2200 pg/ml), a cardial involvement was confirmed. In the bone marrow (from three sites) was found 2.85% clonal plasma cells with immunophenotype СD138+, СD38dim, СD19-, СD117+, СD81-, СD27-, СD56-. FISH method revealed polysomy 5,9,15 in 3% of the nuclei. Serum free light chain Kappa 575 mg/l (/44.9) was detected. Multiple foci of destruction with increased metabolic activity (SUVmax 3.6) were visualized on PET-CT, and an surgical intervention biopsy was performed from two foci. The number of plasma cells from the destruction foci was 2.5%, and massive amyloid deposition was detected. On CT scan foci of lesions differed from bone lesions at multiple myeloma. Bone fragments of point and linear type (button sequestration) were visualized in most of the destruction foci. The content of the lesion was low density. There was no extraossal spread from large zones of destruction. There was also spontaneous scarring of the some lesions (without therapy). Thus, the diagnosis of multiple myeloma was excluded on the basis based on x-ray signs, of the duration of osteodestructive syndrome (15 years), the absence of plasma infiltration in the bone marrow, including from foci of bone destruction by open biopsy. This observation proves the possibility of damage to the skeleton due to amyloid deposition and justifies the need to include AL-amyloidosis in the spectrum of differential diagnosis of diseases that occur with osteodestructive syndrome.

Background: Multiple myeloma bone disease (MMBD) constitutes a common and severe complication of multiple myeloma (MM), impacting the quality of life and survival. We evaluated the clinical value of a panel of 19 miRNAs associated with osteoporosis in MMBD. Methods: miRNAs were isolated from the plasma of 62 newly diagnosed MM patients with or without MMBD. First-strand cDNA was synthesized, and relative quantification was performed using qPCR. Lastly, we carried out extensive biostatistical analysis. Results: Circulating levels of let-7b-5p, miR-143-3p, miR-17-5p, miR-214-3p, and miR-335-5p were significantly higher in the blood plasma of MM patients with MMBD compared to those without. Receiver operating characteristic curve and logistic regression analyses showed that these miRNAs could accurately predict MMBD. Furthermore, a standalone multi-miRNA–based logistic regression model exhibited the best predictive potential regarding MMBD. Two of those miRNAs also have a prognostic role in MM since survival analysis indicated that lower circulating levels of both let-7b-5p and miR-335-5p were associated with significantly worse progression-free survival, independently of the established prognostic factors. Conclusions: Our study proposes a miRNA signature to facilitate MMBD diagnosis, especially in ambiguous cases. Moreover, we provide evidence of the prognostic role of let-7b-5p and miR-335-5p as non-invasive prognostic biomarkers in MM.

Spinal Involvement

Bone disease is observed in almost 80% of newly diagnosed symptomatic multiple myeloma patients, and spine is the bone site that is more frequently affected by myeloma-induced osteoporosis, osteolyses, or compression fractures. In almost 20% of the cases, spinal cord compression may occur; diagnosis and treatment must be carried out rapidly in order to avoid a permanent sensitive or motor defect. Although whole body skeletal X-ray is considered mandatory for multiple myeloma staging, magnetic resonance imaging is presently considered the most appropriate diagnostic technique for the evaluation of vertebral alterations, as it allows to detect not only the exact morphology of the lesions, but also the pattern of bone marrow infiltration by the disease. Multiple treatment modalities can be used to manage multiple myeloma-related vertebral lesions. Surgery or radiotherapy is mainly employed in case of spinal cord compression, impending fractures, or intractable pain. Percutaneous vertebroplasty or balloon kyphoplasty can reduce local pain in a significant fraction of treated patients, without interfering with subsequent therapeutic programs. Systemic antimyeloma therapy with conventional chemotherapy or, more appropriately, with combinations of conventional chemotherapy and compounds acting on both neoplastic plasma cells and bone marrow microenvironment must be soon initiated in order to reduce bone resorption and, possibly, promote bone formation. Bisphosphonates should also be used in combination with antimyeloma therapy as they reduce bone resorption and prolong patients survival. A multidisciplinary approach is thus needed in order to properly manage spinal involvement in multiple myeloma.

There is increasing evidence to suggest that the Wnt signaling pathway plays a critical role in the pathogenesis of myeloma bone disease. In the present study, we determined whether increasing Wnt signaling within the bone marrow microenvironment in myeloma counteracts development of osteolytic bone disease. C57BL/KaLwRij mice were inoculated intravenously with murine 5TGM1 myeloma cells, resulting in tumor growth in bone and development of myeloma bone disease. Lithium chloride (LiCl) treatment activated Wnt signaling in osteoblasts, inhibited myeloma bone disease, and decreased tumor burden in bone, but increased tumor growth when 5TGM1 cells were inoculated subcutaneously. Abrogation of β-catenin activity and disruption of Wnt signaling in 5TGM1 cells by stable overexpression of a dominant-negative TCF4 prevented the LiCl-induced increase in subcutaneous growth but had no effect on LiCl-induced reduction in tumor burden within bone or on osteolysis in myeloma-bearing mice. Together, these data highlight the importance of the local microenvironment in the effect of Wnt signaling on the development of myeloma bone disease and demonstrate that, despite a direct effect to increase tumor growth at extraosseous sites, increasing Wnt signaling in the bone marrow microenvironment can prevent the development of myeloma bone disease and inhibit myeloma growth within bone in vivo.

Abstract Previous work with continuously cultured multiple myeloma lines suggested that cytokine production by tumor cells may mediate some of the medical complications of this disease. To further investigate this issue, we assayed freshly obtained bone marrow (BM) cells from myeloma patients for the in vitro production of cytokines and the presence of cytokine RNA. Production of cytokine protein was assessed by bioassays with the aid of specific neutralizing anticytokine antibodies. These assays detected interleukin-1 (IL-1) and tumor necrosis factor (TNF) secretion by myeloma BM cells, which was significantly greater than secretion from similarly processed BM cells of control individuals. In contrast, lymphotoxin and interleukin-2 (IL-2) production could not be detected. The levels of IL-1 and TNF produced in vitro peaked at 24 hours of culture and correlated with stage and the presence (or absence) of extensive osteolytic bone disease. Northern blot analysis demonstrated the presence of IL-1 beta and TNF RNA in uncultured myeloma BM cells but no detectable IL-1 alpha or lymphotoxin RNA. In addition, the amount of cytokine RNA correlated with protein production, being significantly greater in patients' BM cells than in control marrow. These data suggest a role for IL-1 beta and/or TNF in the pathophysiology of multiple myeloma and argue against a role for lymphotoxin or IL-2.

Multiple myeloma (MM) is a cancerous bone disease characterized by malignant transformation of plasma cells in the bone marrow. MM is considered to be the second most common blood malignancy, with 20,000 new cases reported every year in the USA. Extensive research is currently enduring to validate diagnostic and therapeutic means to manage MM. microRNAs (miRNAs) were shown to be dysregulated in MM cases and to have a potential role in either progression or suppression of MM. Therefore, researchers investigated miRNAs levels in MM plasma cells and created tools to test their impact on tumor growth. In the present review, we discuss the most recently discovered miRNAs and their regulation in MM. Furthermore, we emphasized utilizing miRNAs as potential targets in the diagnosis, prognosis and treatment of MM, which can be useful for future clinical management.

Multiple myeloma (MM) is a plasma cell disorder, characterized by clonal proliferation of malignant plasma cells in the bone marrow. Bone disease is the most frequent feature and an end-organ defining indicator of MM. In this context, imaging plays a pivotal role in the management of the malignancy. For several decades whole-body X-ray survey (WBXR) has been applied for the diagnosis and staging of bone disease in MM. However, the serious drawbacks of WBXR have led to its gradual replacement from novel imaging modalities, such as computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT). PET/CT, with the tracer 18F-fluorodeoxyglucose (18F-FDG), is now considered a powerful diagnostic tool for the detection of medullary and extramedullary disease at the time of diagnosis, a reliable predictor of survival as well as the most robust modality for treatment response evaluation in MM. On the other hand, 18F-FDG carries its own limitations as a radiopharmaceutical, including a rather poor sensitivity for the detection of diffuse bone marrow infiltration, a relatively low specificity, and the lack of widely applied, established criteria for image interpretation. This has led to the development of several alternative PET tracers, some of which with promising results regarding MM detection. The aim of this review article is to outline the major applications of PET/CT with different radiopharmaceuticals in the clinical practice of MM.
