Daratumumab or Active Monitoring for High-Risk Smoldering Multiple Myeloma.

Background: Daratumumab, an anti-CD38 monoclonal antibody, has been approved for the treatment of multiple myeloma. Data are needed regarding the use of daratumumab for high-risk smoldering multiple myeloma, a precursor disease of active multiple myeloma for which no treatments have been approved.

Methods: In this phase 3 trial, we randomly assigned patients with high-risk smoldering multiple myeloma to receive either subcutaneous daratumumab monotherapy or active monitoring.

Relationship between reasons for intermittent missing patient-reported outcomes data and missing data mechanisms.

Purpose: Non-response (NR) to patient-reported outcome (PRO) questionnaires may cause bias if not handled appropriately. Collecting reasons for NR is recommended, but how reasons for NR are related to missing data mechanisms remains unexplored. We aimed to explore this relationship for intermittent NRs.

Early, Patient-Centered, and Multidisciplinary Approach in Newly Diagnosed Multiple Myeloma: What Are We Talking About? A Case Description and Discussion.

Specialized palliative care (SPC) is a multidisciplinary need-based approach from the time a life-threatening disease is diagnosed. Patients with multiple myeloma (MM) will, at the time of diagnosis, often present with symptoms and needs that require a multidisciplinary approach. This case describes the course of a patient with newly diagnosed MM, involving all vertebrae and with no common analgesic treatment providing sufficient relief.

Screening for Cardiac Amyloidosis 5 to 15 Years After Surgery for Bilateral Carpal Tunnel Syndrome.

Background: Bilateral carpal tunnel syndrome (CTS) is a common extracardiac manifestation of amyloidosis and usually predates overt cardiac amyloidosis (CA) by several years. Screening studies on patients undergoing CTS surgery have shown a low yield of CA (2.0%), but high prevalence of amyloid in the carpal ligament.

Strategies to improve patient-reported outcome completion rates in longitudinal studies.

Purpose: The quality of patient-reported outcome (PRO) data can be compromised by non-response (NR) to scheduled questionnaires, particularly if reasons for NR are related to health problems, which may lead to unintended bias. The aim was to investigate whether electronic reminders and real-time monitoring improve PRO completion rate.

Methods: The population-based study "Quality of life in Danish multiple myeloma patients" is a longitudinal, multicentre study with consecutive inclusion of treatment-demanding newly diagnosed or relapsed patients with multiple myeloma.

Chemerin is elevated in multiple myeloma patients and is expressed by stromal cells and pre-adipocytes.

Chemerin is a recently discovered adipokine shown to be involved in both inflammatory and metabolic processes. Here, we demonstrate that chemerin serum levels are elevated in patients with multiple myeloma and that it increases with disease progression. We found that chemerin is expressed by stromal cells and preadipocytes, whereas its receptor CCRL2 is expressed by primary myeloma cells, suggesting a paracrine signaling loop between bone marrow stromal cells/adipocytes and myeloma cells.

N-terminal pro-C-type natriuretic peptide in serum associated with bone destruction in patients with multiple myeloma.

Aim: To examine whether N-terminal proCNP concentrations in serum is associated with bone destruction in patients with multiple myeloma.

Materials & Methods: N-terminal proCNP and biochemical bone markers were measured in 153 patients. Radiographic bone disease and skeletal-related events were evaluated at specific time-points.

Activin A inhibits BMP-signaling by binding ACVR2A and ACVR2B.

Background: Activins are members of the TGF-β family of ligands that have multiple biological functions in embryonic stem cells as well as in differentiated tissue. Serum levels of activin A were found to be elevated in pathological conditions such as cachexia, osteoporosis and cancer. Signaling by activin A through canonical ALK4-ACVR2 receptor complexes activates the transcription factors SMAD2 and SMAD3.

Serum YKL-40: a new independent prognostic marker for skeletal complications in patients with multiple myeloma.

In a time of increasing treatment options for multiple myeloma bone disease, risk factors predicting progression need to be elucidated. This study investigated the value of serum YKL-40, previously shown to be associated with radiographic progression of bone destruction, as a predictor for time to clinical progression, i.e.

Plasma YKL-40 and total and disease-specific mortality in the general population.

Background: Increased plasma YKL-40 is associated with short-term survival in patients with cardiovascular disease and cancer. We tested the hypothesis that increased plasma YKL-40 is associated with total and disease-specific mortality in the general population.

Methods: We measured plasma YKL-40 in 8899 study participants, aged 20-95 years, in the Copenhagen City Heart Study from the Danish general population who were followed for 16 years: 3059 died, 2158 had ischemic cardiovascular disease, 2271 had cancer, and 2820 had other diseases associated with increased YKL-40.

Multiparametric flow cytometry profiling of neoplastic plasma cells in multiple myeloma.

Background And Aim: The clinical impact of multiparametric flow cytometry (MFC) in multiple myeloma (MM) is still unclear and under evaluation. Further progress relies on multiparametric profiling of the neoplastic plasma cell (PC) compartment to provide an accurate image of the stage of differentiation. The primary aim of this study was to perform global analysis of CD expression on the PC compartment and subsequently to evaluate the prognostic impact.

Elevated plasma YKL-40 predicts increased risk of gastrointestinal cancer and decreased survival after any cancer diagnosis in the general population.

Purpose: Elevated plasma YKL-40 is a biomarker of poor prognosis in cancer patients. We tested the hypotheses that elevated plasma YKL-40 predicts risk of cancer as well as survival after a cancer diagnosis in the general population.

Patients And Methods: A prospective cohort study of 8,899 subjects (20 to 95 years) from the Danish general population, the Copenhagen City Heart Study, observed for 11 years for cancer incidence and 14 years for death: 1,432 participants had a first incident cancer, 968 of these died.

Report of the European Myeloma Network on multiparametric flow cytometry in multiple myeloma and related disorders.

The European Myeloma Network (EMN) organized two flow cytometry workshops. The first aimed to identify specific indications for flow cytometry in patients with monoclonal gammopathies, and consensus technical approaches through a questionnaire-based review of current practice in participating laboratories. The second aimed to resolve outstanding technical issues and develop a consensus approach to analysis of plasma cells.

High serum YKL-40 concentration is associated with severe bone disease in newly diagnosed multiple myeloma patients.

Objectives: In multiple myeloma (MM) YKL-40 is present in the bone marrow microenvironment and is suggested to play a role in remodelling of the extracellular matrix. Here, the association between serum YKL-40 and severity of bone disease in MM is investigated.

Methods: Serum YKL-40 was measured in 34 MM patients at diagnosis.

Serum YKL-40 concentrations in newly diagnosed multiple myeloma patients and YKL-40 expression in malignant plasma cells.

Objectives: A potential role in cancer biology is suggested for YKL-40 (CHI3L1, HC gp-39). The purpose of this study was to evaluate the clinical value of serum YKL-40 (sYKL-40) in multiple myeloma (MM) and to examine YKL-40 expression in malignant plasma cells (MM PCs).

Methods: sYKL-40 was measured by enzyme-linked immunosorbent assay (ELISA) in 82 patients with newly diagnosed MM.

High serum concentration of YKL-40 is associated with short survival in patients with acute myeloid leukemia.

Purpose: YKL-40 is secreted by cancer cells, macrophages, and neutrophils. It may be a growth or differentiation factor, play a role in angiogenesis, or protect against apoptosis. High serum YKL-40 is associated with poor prognosis in solid carcinomas.
