Abstract

The immunological bone marrow (BM) microenvironment plays a major role in controlling growth and survival of clonal plasma cells (PC); this might translate into different patterns of expression of molecules involved in immune responses on PC from different types of monoclonal gammopathies (MG). We have studied the expression of a group of nine such molecules on both BMPC and the plasma of 61 newly diagnosed MG patients (30 MG of undetermined significance (MGUS), 27 multiple myeloma (MM) and four plasma cell leukemia (PCL)) and five normal individuals. Clonal PC from all MG displayed significantly increased levels of CD56, CD86 and CD126, and decreased amounts of CD38 (P<0.001). Additionally, HLA-I and beta2-microglobulin were abnormally highly expressed in MGUS, while CD40 expression was decreased in MM and PCL (P<0.05). Interestingly, a progressive increase in the soluble levels of beta2-microglobulin was found from MGUS to MM and PCL patients (P=0.03). In contrast, all groups showed similar surface and soluble amounts of CD126, CD130 and CD95, except for increased soluble levels of CD95 observed in PCL. Overall, those phenotypic differences are consistent with increased antigen presentation and costimulatory capacities in MGUS, which progressively deteriorate in malignant MG (MM and PCL).

Abstract

The aim of this study was to analyse the expression of NK-associated antigens in both peripheral blood and bone marrow lymphocytes from a large series of newly diagnosed multiple myeloma patients. 112 patients with untreated multiple myeloma (MM) were included in the study. 36 sex- and age-matched healthy volunteers were used as controls for peripheral blood (PB) studies and 14 for the bone marrow (BM) studies. Simultaneous stainings with the CD3/CD56, CD2/CD16 and CD8/CD57 monoclonal antibodies were systematically performed in PB and CD3/CD56 and CD2/CD16 in BM in order to analyse their relationship with the clinical and biological characteristics of the disease and survival. The expression of NK-associated antigens (CD56, CD16 and CD57) assessed within the lymphoid gate, was significantly increased (P < 0.001) in the PB of MM patients both in relative and absolute numbers. In the BM a significant increase in the percentage of CD56+ lymphocytes (P < 0.001) was also observed; in contrast, the proportion of CD16+ cells did not differ significantly from that of normal BM samples. The number of CD56+CD3- lymphocytes increased significantly within high-risk patients (869 +/- 671) as compared to intermediate (388 +/- 212) and low-risk patients (274 +/- 199) (P = 0.04). Moreover, patients with high values of CD56+CD3- lymphocytes showed a statistically significant association with several adverse prognostic factors including anaemia, hypoalbuminaemia, renal failure, high beta 2M, DNA diploidy and high S-phase plasma cells. In addition, patients with higher absolute numbers of PB CD56+CD3-lymphocytes displayed a poorer prognosis, whereas patients with higher values of CD57+CD8- cells had a better outcome.

Abstract

Granulocytic myeloid-derived suppressor cells (G-MDSCs) promote tumor growth and immunosuppression in multiple myeloma (MM). However, their phenotype is not well established for accurate monitoring or clinical translation. We aimed to provide the phenotypic profile of G-MDSCs based on their prognostic significance in MM, immunosuppressive potential, and molecular program. The preestablished phenotype of G-MDSCs was evaluated in bone marrow samples from controls and MM patients using multidimensional flow cytometry; surprisingly, we found that CD11b+CD14−CD15+CD33+HLADR− cells overlapped with common eosinophils and neutrophils, which were not expanded in MM patients. Therefore, we relied on automated clustering to unbiasedly identify all granulocytic subsets in the tumor microenvironment: basophils, eosinophils, and immature, intermediate, and mature neutrophils. In a series of 267 newly diagnosed MM patients (GEM2012MENOS65 trial), only the frequency of mature neutrophils at diagnosis was significantly associated with patient outcome, and a high mature neutrophil/T-cell ratio resulted in inferior progression-free survival (P < .001). Upon fluorescence-activated cell sorting of each neutrophil subset, T-cell proliferation decreased in the presence of mature neutrophils (0.5-fold; P = .016), and the cytotoxic potential of T cells engaged by a BCMA×CD3-bispecific antibody increased notably with the depletion of mature neutrophils (fourfold; P = .0007). Most interestingly, RNA sequencing of the 3 subsets revealed that G-MDSC–related genes were specifically upregulated in mature neutrophils from MM patients vs controls because of differential chromatin accessibility. Taken together, our results establish a correlation between the clinical significance, immunosuppressive potential, and transcriptional network of well-defined neutrophil subsets, providing for the first time a set of optimal markers (CD11b/CD13/CD16) for accurate monitoring of G-MDSCs in MM.

Abstract

Multiple myeloma (MM) is a malignancy of terminally differentiated B lymphocytes, characterized by accumulation of a monotypic plasma cell population in the bone marrow, monoclonal immunoglobulin in serum and/or urine and osteolytic lesions. Despite recent advances in the treatment, MM remains an incurable disease. This calls for an effort to develop novel therapeutics in order to eradicate the disease. Here we have evaluated the potential antimyeloma action of Pemetrexed, an antifolate drug that has shown promising results in other neoplastic diseases. Pemetrexed had a potent antimyeloma effect on cell lines sensitive and resistant to conventional therapeutic agents, and was also efficient on fresh cells from patients and in a murine MM model. Furthermore, Pemetrexed abrogated the protective action on MM cell death of several growth factors produced by the bone marrow microenvironment. Mechanistic studies indicated that Pemetrexed provoked this action by a combined effect that included cell cycle blockade, probably by p21 upregulation, and induction of apoptosis through caspase-dependent and -independent mechanisms. These data, together with the fact that Pemetrexed is already licensed for the therapy of other neoplastic diseases, opens the possibility for the inclusion of Pemetrexed in the therapeutic armamentarium to battle MM.Leukemia (2007) 21, 797–804. doi:10.1038/sj.leu.2404599; published online 22 February 2007 [ABSTRACT FROM AUTHOR]

Abstract

These Clinical Practice Guidelines are endorsed by the Japanese Society of Medical Oncology (JSMO) incidence and epidemiology Multiple myeloma (MM) accounts for 1% of all cancers and ∼10% of all haematological malignancies. The incidence in Europe is 4.5–6.0/100 000/year with a median age at diagnosis of between 65 and 70 years; the mortality is 4.1/100 000/year. Almost all patients with MM evolve from an asymptomatic pre-malignant stage termed monoclonal gammopathy of undetermined significance (MGUS). MGUS progresses to MM at a rate of 1% per year. In some patients, an intermediate asymptomatic but more advanced pre-malignant stage termed smouldering (or indolent) multiple myeloma (SMM) can be recognised. SMM progresses to myeloma at a rate of 10% per year over the first 5 years following diagnosis, 3% per year over the following 5 years and 1.5% per year thereafter [1]. diagnosis Diagnosis of MM should be based on the following tests: [1] -Detection and evaluation of the monoclonal (M-) component by serum and/or urine protein electrophoresis (concentrate of 24 h urine collection); nephelometric quantification of IgG, IgA and IgM immunoglobulins; characterisation of the heavy and light chains by immunofixation; and serum-free light-chain (FLC) measurement; -Evaluation of bone marrow (BM) plasma cell infiltration: BM aspiration and/or biopsies are the standard options to evaluate the number and characteristics. Moreover, the BM sample should be used for cytogenetic/fluorescence in situ hybridization (FISH) studies and also has the potential for immunophenotypic and molecular investigations; -Evaluation of lytic bone lesions: a radiological skeletal bone survey, including spine, pelvis, skull, humeri and femurs is necessary. A magnetic resonance imaging (MRI) or computed tomography (CT) scan may be needed to evaluate symptomatic bony sites, even if the skeletal survey is negative and the patient has symptoms suggesting bone lesions. Moreover, MRI provides greater detail and is recommended whenever spinal cord compression is suspected. Fluorodeoxyglucose positron emission tomography is currently under evaluation but should not be systematically used; -Complete blood cell count, with differential serum creatinine and calcium level.
