The clinical significance of CD49e and CD56 for multiple myeloma in the novel agents era. Med Oncol 2020; 37:103.

Abstract
Multiple myeloma (MM) is a hematological malignancy characterized by the proliferation of abnormal plasma cells in bone marrow. Flow cytometry distinguishes between normal and abnormal plasma cells by evaluating cluster of differentiation (CD) 56 and CD19 expression patterns. Moreover, immunophenotyping of mature plasma cell 1 (MPC-1) and very late antigen-5 (CD49e) identifies the maturity of MM as mature (MPC-1+, CD49e+), intermediate (MPC-1+, CD49e-), or immature (MPC-1-, CD49e-). We retrospectively examined the effects of surface marker expression and maturity subtype on overall survival (OS) and time to next treatment (TNT) among 55 patients (25 males, 30 females) with symptomatic MM. All patients were treated with regimens containing bortezomib (BOR) (n = 39) or lenalidomide (LEN) (n = 16) as the initial treatment. Median age at diagnosis was 72 years (range: 36-88). The lack of CD56, an aberrant marker, was associated with significantly worse prognosis compared with CD56+ MM (median OS: 24 vs. 60 months, respectively; p = 0.0050). In CD49e+ MM, defined as mature type, no significant difference was seen in TNT of the initial treatment, regardless of whether it was a BOR-based regimen or LEN + dexamethasone (Ld) therapy. On the other hand, in CD49e- MM, defined as immature/intermediate type, TNT of Ld therapy was significantly longer than that of BOR-based regimens (median TNT: undefined vs. 12 months, respectively; p = 0.0043). These results suggest that Ld therapy is more effective than BOR-based therapy for CD49e- MM and thus may aid regimen-related decisions in the novel agents era.

Abstract
In the present study, the effect of immunophenotyping on the prognoses of patients with multiple myeloma (MM) treated with bortezomib plus dexamethasone was investigated. The study involved 46 patients with MM, and analyzed the prognostic significance of the expression of cluster of differentiation (CD)45, CD56 and mature plasma cell (MPC)-1, and other factors including the International Staging System (ISS) stage, age, gender, the immunoglobulin subtype and the treatment line number prior to bortezomib treatment. Although CD56 and MPC-1 expression did not appear to affect the time to next treatment (TNT) or overall survival rate (OS), the univariate analysis determined that CD45 positivity was an adverse prognostic factor for TNT and OS, and that being male was significantly associated with inferior TNT and OS. Multivariate analyses determined that CD45 expression was prognostically significant for TNT and OS. In conclusion, CD45 positivity is an adverse prognostic factor in MM patients treated with bortezomib. The data from the present study demonstrate the clinical importance of classifying MM cells immunophenotypically to determine the prognoses of patients.

Abstract
Multiple myeloma (MM) is a malignant tumor of plasma cells in the bone marrow. Interleukin 6 (IL-6) is an indispensable growth factor for myeloma cells. The heterogeneity of myeloma cells are the characteristics of MM, categorized into five sub-populations, two immature cells, MPC-1<PRE>-</PRE> CD49e<PRE>-</PRE> CD45<PRE>+/-</PRE>, intermediate cells, MPC-1<PRE>+</PRE> CD49e<PRE>-</PRE> CD45<PRE>+/-</PRE>, and mature cells, MPC-1<PRE>+</PRE> CD49e<PRE>+</PRE> CD45<PRE>+</PRE>. Only MPC-1<PRE>-</PRE> CD49e<PRE>-</PRE> CD45<PRE>+</PRE> immature cells (∼2% of total myeloma cells) respond to IL-6 to proliferate. CD45 protein tyrosine phosphatase is the determinant of IL-6 dependent cell growth of myeloma cells, although well studied IL-6 signal transducing factors, such as, IL-6Ra, gp130, Jak2, STAT3, and MAPK, are activated and involved in the process. Immature CD45<PRE>-</PRE> cells converted to CD45<PRE>+</PRE> cells after IL-6 stimulation both in U266 cells and sorted myeloma cells from the bone marrow aspirates of MM patients. CD45<PRE>-</PRE> cells are relatively resistant to serum starvation compared to CD45<PRE>+</PRE> cells. Because IL-6 level in the bone marrow is low even in MM patients, the CD45<PRE>-</PRE> phenotype of myeloma cells may protect the cells from apoptosis. These findings of a tuning effect of CD45 on myeloma cell proliferation may aid the study of IL-6 dependent proliferation of myeloma cells and lead to the development of new therapies for MM patients.

Abstract
The heterogeneity of bone marrow plasmacytosis is clearly analyzed by multicolor staining with anti-CD38 antibody. To date, at least 5 subpopulations of plasma cells have been identified in the bone marrow of multiple myeloma (MM) patients with regard to the expression of MPC-1, CD49e (VLA-5), and CD45: MPC-1(-)CD49e(-)CD45(+) proliferative immature cells, MPC-1(-)CD49e(-)CD45(-) immature myeloma cells, MPC-1(+)CD49e(-)CD45(-) and MPC-1(+)CD49e(-)CD45(+) intermediate myeloma cells, and MPC-1(+)CD49e(+)CD45(+) mature myeloma cells. We performed phenotypic analyses in 75 cases of monoclonal bone marrow plasmacytosis, including 46 cases of MM and 29 cases of monoclonal gammopathy of undetermined significance (MGUS). In 31 cases of progressive MM disease, MPC-1(-) immature and MPC-1(-)CD45(+) proliferative immature myeloma cells were significantly increased up to >25% and >10%, respectively, of the plasma cell fractions (CD38(++) cells), whereas there were no increases in MPC-1(-) or MPC-1(-)CD45(+) proliferative immature myeloma cells in 15 cases of stable disease. Interestingly, the proportions of MPC-1(-) and MPC-1(-)CD45(+) immature monoclonal plasma cells also increased in the 7 progressive cases of MGUS. Finally, we present the revised (2005) phenotypic classification of monoclonal marrow plasmacytosis (MOMP-2005).

Abstract
Cell lines RPMI 8226, JJN3, U266 B1, NCI-H929 (all EBV-) and ARH77 and HS-Sultan (both EBV+) have been extensively characterized in this study. EBV- lines expressed the phenotype (CD138-, CD19+, CD20+) whereas EBV+ were (CD138+, CD19-, CD20-). CD56 expression was restricted to EBV- cell lines, with the exception of U266 B1, whereas PCA-1 was strongly expressed on five of the six cell lines. Only EBV+ cell lines bound peanut-agglutinin (PNA). However, all cell lines bound the lectin Jacalin that binds the same receptor as PNA, irrespective of the receptors sialylation status. By RT-PCR and direct sequencing of their IgH V/D/J domains, ARH77 was demonstrated to use the germline sequence VH4-34/dm1/JH6b, whereas no arrangement was demonstrated for RPMI 8226, suggesting IgH gene deletion or mutation. HLA class I and II antigens were detected using HLA typing on all cell lines warranting their use as suitable targets for HLA-restricted cytotoxic T cells. By sensitive RT-PCR, mRNA for IL-6, IL-6R and TNFbeta was found expressed in all cell lines. IL-1 mRNA expression was predominantly associated with the EBV+ phenotype. Although mRNA for IL-3 and GM-CSF was never detected, transcripts for c-kit ligand and, more commonly, its receptor were. Likewise GM-CSF, M-CSF and erythropoietin mRNA transcripts were detected in the majority of cell lines.

Abstract
The diagnosis of multiple myeloma (MM) is often difficult; most patients present with asymptomatic gammopathy. The only findings that confirm a diagnosis of MM are an elevation in the M-component or extension of the lytic bone lesions that are the hallmark of the disease. Tests that delineate plasma cell biology, such as plasma cell proliferation rate, are helpful; magnetic resonance imaging can disclose bone marrow lesions leading to subsequent osteolytic disease. After the diagnosis of MM has been established and prognostic factors identified, the appropriate therapy can be determined. Melphalan and prednisone are no longer considered to be the "gold standard" of therapy. In fact, this approach is suitable for less than half of patients with myeloma. This article presents guidelines for standard treatment options and examines the efficacy of new high-dose chemotherapy approaches.
