BACKGROUND: Serum free light chain assay (SFLCA) and κ/λ ratio, and protein electrophoretic methods are used in the diagnosis and monitoring of monoclonal gammopathies. METHODS: Results for serum free light chains, serum and urine protein electrophoreses and immunofixation electrophoreses in 468 patients with a diagnosis of monoclonal gammopathy were compared. The results of the two methods were graded as concordant, non-concordant or discordant with the established diagnoses to assess the relative performance of the methods...

Monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are precursor conditions of symptomatic multiple myeloma (MM). Diagnostic principles are aimed at excluding MM requiring therapy, other conditions associated with paraproteins that may require different management, and risk stratifying patients for the purposes of tailored follow-up and investigation. The International Myeloma Working Group have recently published a revised definition of MM, which singles out a small group of patients with smoldering multiple myeloma who are at very high risk of progression and organ damage; such patients are now included under the definition of MM and recommended to start anti-myeloma treatment...

Multiple myeloma (MM) has been diagnosed based on the International Myeloma Working Group (IMWG) diagnostic criteria since 2003. In 2014, the IMWG updated these diagnostic criteria to add three specific biomarkers, i.e., 1) Clonal bone marrow plasma cell percentage ≥60%; 2) Involved: uninvolved serum free light chain ratio ≥100; 3) >1 focal lesion on MRI studies, based on CRAB features (hypercalcemia, renal failure, anemia, and bone lesions). An early diagnosis of MM can be made, allowing timely anti-MM treatment, in patients with the ultra-high-risk smoldering form of this disease...

We present an 88-year-old male with simultaneous T-cell prolymphocytic leukemia and stable smoldering myeloma with excellent initial response to three months of alemtuzumab. The patient relapsed at twelve months with severe cutaneous disease. Biopsy of a representative plaque demonstrated CD30 positivity in rare malignant lymphocytes. The patient demonstrated no response to reintroduction with a full course of alemtuzumab. He was therefore treated with brentuximab vedotin, resulting in partial remission of skin involvement that persisted for three months...

All cases of multiple myeloma (MM) are preceded by precursor states termed monoclonal gammopathy of undetermined significance (MGUS) or smoldering myeloma (SMM). Genetic analyses of MGUS cells have provided evidence that it is a genetically advanced lesion, wherein tumor cells carry many of the genetic changes found in MM cells. Intraclonal heterogeneity is also established early during the MGUS phase. Although the genetic features of MGUS or SMM cells at baseline may predict disease risk, transition to MM involves altered growth of preexisting clones...

Periostin is an extracellular matrix protein that is implicated in the biology of normal bone remodeling and in different cancer cell growth and metastasis. However, there is no information on the role of periostin in multiple myeloma (MM). Thus, we evaluated periostin in six myeloma cell lines in vitro; in the bone marrow plasma and serum of 105 newly diagnosed symptomatic MM (NDMM) patients and in the serum of 23 monoclonal gammopathy of undetermined significance (MGUS), 33 smoldering MM (SMM) patients, 30 patients at the plateau phase post-first-line therapy, 30 patients at first relapse and 30 healthy controls...

Monoclonal gammopathies are characterized by serum monoclonal component (MC) plus an intact immunoglobulin and a free light chain (FLC), or a combination of both. The measurement of FLC with Freelite(®) is the standard practice recommended by International Myeloma Working Group guidelines. Recently, Hevylite(®) heavy/light chains (HLC) assays were introduced to specifically target junctional epitopes between the heavy and light chains of intact immunoglobulins, allowing the independent quantification of the involved (MC) and uninvolved (polyclonal immunoglobulin background) HLC isotype...

Monoclonal gammopathy of undetermined significance (MHUS) is characterized by the presence of a serum M-protein less than 3 g/dL, less than 10 % clonal plasma cells in the bone marrow, and the absence of myeloma-defining event. Smoldering multiple myeloma (SMM) is an asymptomatic disorder characterized by the presence of ≥3 g/dL serum M-protein and/or 10-60 % bone marrow plasma cell infiltration with no myeloma-defining event. The risk of progression to multiple myeloma (MM) requiring therapy varies greatly for individual patients, but it is uniform and 1 % per year for MGUS, while higher (10 % per year) and not uniform for SMM patients...

BACKGROUND: Aberrant DNA methylation is considered a crucial mechanism in the pathogenesis of monoclonal gammopathies. We aimed to investigate the contribution of hypermethylation of 4 tumor suppressor genes to the multistep process of myelomagenesis. METHODS: The methylation status of p15, p16, p53, and DAPK genes was evaluated in bone marrow samples from 94 patients at diagnosis: monoclonal gammopathy of uncertain significance (MGUS) (n = 48), smoldering multiple myeloma (SMM) (n = 8) and symptomatic multiple myeloma (MM) (n = 38), and from 8 healthy controls by methylation-specific polymerase chain reaction analysis...

There have been major recent advancements in the understanding and management of multiple myeloma. Diagnostic criteria have been revised and former ultra-high-risk smoldering multiple myeloma is now considered multiple myeloma in need of treatment. Understanding clonal progression, evolution, and tides not only has helped elucidate the disease behavior but might help expand therapeutic choices in order to select appropriate treatment for patients. Unprecedented response rates with modern triplet induction therapies containing proteasome inhibitor and immunomodulators have made this approach standard for initial treatment...

PURPOSE OF REVIEW: Although the input of multiparameter flow cytometry (MFC) into the clinical management of multiple myeloma patients has faced some reluctance, continuously growing evidence supports the utility of MFC in this disease. RECENT FINDINGS: MFC immunophenotyping of bone marrow and peripheral blood plasma cells affords cost-effective assessment of clonality, and provides prognostic information on the risk of progression in smoldering multiple myeloma, and the identification of active multiple myeloma patients with dismal outcome (e...

Epidemiologically, multiple myeloma (MM) is a malignant disorder of plasma cells with a higher incidence among Western populations than among Asians. However, there is growing evidence of a recent increase in the age-standardized incidence rate (ASR) of MM in Asian countries, particularly Korea. Application of novel agents has resulted in significant improvement of treatment outcomes, and the advances are ongoing with the recent introduction and U.S. Food and Drug Administration's approval of newer agents, including carfilzomib, ixazomib, elotuzumab, and daratumumab...

An active role for the immune system in controlling the malignant plasma cell clone in myeloma has been postulated for many years. The clinical states of monoclonal gammopathy of undetermined significance, plateau phase disease, and smoldering myeloma all suggest that a significant host-tumor interaction is taking place. The fundamental role of the cytotoxic T cell in tumor elimination and control has been exemplified by the dramatic efficacy of adoptive T-cell therapies in many hemopoietic malignancies. However, tumor-host cross-talk results in suppression of the endogenous cytotoxic T-cell response against the malignant plasma cell...

A 64- year-old man with smoldering myeloma presented to the hospital for nausea, vomiting, and PO intolerance. Abdominal CT demonstrated massive gastric distention and collapsed proximal duodenum consistent with gastric outlet obstruction (GOO). Esophagogastroduodenoscopy demonstrated pyloric edema. Duodenal biopsies were consistent with AL amyloidosis. Given the concerns for bleeding risk and immediate need to start chemotherapy, surgery was deferred. Chemotherapy was initiated with a good clinical response...

The incidence of second primary malignancies (SPMs) in Japanese patients with myeloma or myeloma-related diseases was studied by using the Kansai Myeloma Forum (KMF) database registered from November 2012 to March 2015. We studied 1,571 cases. Hematologic malignancies were documented in 10 patients, and solid tumors in 36 during this period. The cumulative 5-year incidence was estimated to be 1.0% for hematological malignancies and 3.7% for solid tumors. In the patients with smoldering myeloma or MGUS without treatment, solid tumors but not hematologic malignancies developed, though the cumulative incidence of each malignancy did not differ significantly from that in patients receiving treatment...
