The emerging therapeutic landscape of relapsed/refractory multiple myeloma.

From a historic lens, treatment for patients with relapsed/refractory multiple myeloma (R/R MM) has advanced significantly since the advent of immunomodulatory agents (IMiDs) in the 1990s, proteasome inhibitors in the 2000s, monoclonal antibodies in the 2010s, and CAR-T treatments in the 2020s. However, the availability of multiple new therapies has also created significant ambiguity regarding therapy selection and sequencing, as consensus guidelines are limited, and cross-trial comparisons of the novel agents are challenging. In this focused review, we discuss the novel Food & Drug Administra…

Identification of Immune-Related Hub Genes in Multiple Myeloma

Purpose: Multiple myeloma(MM) is a common malignant tumor in the blood system. Despite recent advances in its treatment, its symptomatic remission rate and survival rate are still not optimistic. In the future, it is necessary to continue to search for different treatment targets and new treatment methods in order to improve the quality of life and survival time of patients with MM. The study aims to explore the potential immune related pivotal genes and immune infiltration patterns in MM. Methods: : The study included peripheral blood samples from patients with MM who our hospital from Octobe…

Integrative medicine in multiple myeloma and plasma cell disorders.

INTRODUCTION: Integrative Medicine (IM) use and efficacy is poorly defined in those with plasma cell disorders (PCD). A 69-question survey on the subject was hosted on HealthTree.org for 3 months. METHOD: The survey included questions about complementary practice use, PHQ-2 score, quality of life, and more. Mean outcome values were compared between IM users and non-users. Proportions of supplement users and IM patients were compared between patients currently on myeloma specific treatment and patients not currently on treatment. RESULTS: The top 10 IM modalities reported among 178 participan

Prevention of infections including vaccination strategies in multiple myeloma.

Infections are a major cause of morbidity and mortality in multiple myeloma. The increased risk for bacterial and viral infections results mainly from the disease-inherent and treatment-induced immunosuppression. Additional risk factors are older age with immune senescence, T cell depletion, polymorbidity, and male gender. Hence, every effort should be taken to reduce the risk for infections by identifying patients at higher risk for these complications and by implementing prophylactic measures, including chemoprophylaxis and immunization against various relevant pathogens. Here, we review the…

GPER1 Активация Антитуморной активности в Множестве миелом.

G белковый рецептор эстрогена. 1 Активация (GPER1) становится перспективной терапевтической стратегией борьбы с различными видами рака. Несмотря на то, что в контексте твердых опухолей широко изучался вопрос о адресации GPER, его воздействие на гематологию еще предстоит понять в полной мере. Здесь мы показываем, что GPER1 mRNA понижается в плазменных клетках от открытой множественной миэломы (MM) и лейкемии от плазмы по сравнению с нормальными спонсорами или преднасыщенными условиями (моноклональная гаммопатия неопределённого значения и удушающая MM); кроме того, более низкое выражение GPER1 а

G protein-coupled estrogen receptor 1 (GPER1) activation is emerging as a promising therapeutic strategy against several cancer types. While … to be fully understood. Here, we show that GPER1 mRNA is down-regulated in plasma cells from overt multiple myeloma (MM) and plasma cell leukemia patients as compared to normal donors or pre-malignant conditions (monoclonal gammopathy of undetermined significance and smoldering MM); moreover, lower GPER1 expression associates with worse overall survival of MM pat …

Cardiovascular Toxicity of Proteasome Inhibitors in Multiple Myeloma Therapy.

The treatment for multiple myeloma has advanced significantly over the past few decades. Proteasome inhibitors have become the cornerstone of the treatment of multiple myeloma. However, proteasome inhibitors have shown cardiovascular complications such as hypertension, pulmonary hypertension, heart failure, arrhythmias, ischaemic heart disease and thromboembolism. Detection, monitoring and management of proteasome inhibitor-related cardiovascular toxicity are essential to improve clinical outcomes for patients. Proposed mechanisms of proteasome inhibitor-related cardiovascular toxicity are apo…

Antibodies and bispecifics for multiple myeloma: effective effector therapy.

The therapeutic landscape in multiple myeloma (MM) has changed dramatically over the last 2 decades. With the introduction of novel immunotherapies, patients with MM can expect deeper responses, longer remissions, and improved overall survival. Since its approval by the US Food and Drug Administration in 2015, the monoclonal antibody specific for CD38, daratumumab, has been incorporated into both frontline and relapsed treatment regimens. Its role as a maintenance therapy is currently being explored. Subsequently, a variety of novel antibody therapeutics have evolved from the success of daratu…

Adhesion molecules in multiple myeloma oncogenesis and targeted therapy.

Every day we march closer to finding the cure for multiple myeloma. The myeloma cells inflict their damage through specialized cellular meshwork and cytokines system. Implicit in these interactions are cellular adhesion molecules and their regulators which include but are not limited to integrins and syndecan-1/CD138, immunoglobulin superfamily cell adhesion molecules, such as CD44, cadherins such as N-cadherin, and selectins, such as E-selectin. Several adhesion molecules are respectively involved in myelomagenesis such as in the transition from the precursor disorder monoclonal gammopathy of…

How to Manage Patients with Lenalidomide-Refractory Multiple Myeloma.

Although lenalidomide-based combinations, such as lenalidomide plus a proteasome inhibitor or an anti-CD38 monoclonal antibody, improve the overall response rate, progression-free survival, and overall survival of patients with relapsed/refractory multiple myeloma (RRMM), there is a tendency to use these regimens as a frontline treatment. This strategy has led to the development of refractoriness early in the disease course, usually after the patient's first treatment. Since lenalidomide-free regimens have so far shown limited efficacy in lenalidomide-refractory patients, there is an unmet nee…

Newly diagnosed multiple myeloma: making sense of the menu.

The development of new drugs and subsequent novel combinations for the treatment of newly diagnosed multiple myeloma (NDMM) has resulted in a plethora of treatment options that can make the choice of initial induction therapy a challenge. A greater understanding of both patient- and disease-specific factors can provide a personalized approach to help design a treatment course. Historically, the choice of an induction regimen has been tethered to an initial impression of transplant eligibility at the time of diagnosis. As more effective and better-tolerated induction regimens have emerged, ther…

Characterizing the Patient Journey in Multiple Myeloma: Qualitative Review.

BACKGROUND: The patient experience of multiple myeloma (MM) is multifaceted and varies substantially between individuals. Current published information on the patient perspective and treatment of MM is limited, making it difficult to gain insights into patient needs regarding the condition. OBJECTIVE: In this review, a combined research method approach (ie, the review of published literature and social media posts) was undertaken to provide insight into patients' perspectives on the burden and treatment of MM, the impact of the COVID-19 pandemic, and the impact of MM on caregivers of patients…

Myelomatous ascites and pleural effusion in relapsed multiple myeloma.

Extramedullary multiple myeloma is seen in advanced and aggressive disease and occurs due to plasma cell infiltration of sites other than the bone marrow. Myelomatous ascites or pleural effusion is seen in less than 1% of cases and can be differentiated from infectious etiologies based on fluid cytology.

Multimodality Molecular Imaging in Arthropathy Associated with Multiple Myeloma.

We report a patient with multiple myeloma (MM) and polyarthritis of large joints. During the staging of the disease, bone marrow diffusely involved by MM was clearly demonstrated by 99mTc-2-methoxy-isobutyl-isonitrile (MIBI) single-photon emission computed tomography/computed tomography (SPECT/CT) but not by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/CT images. On the other hand, a very intense uptake of 18F-FDG was detected in periarticular tissues of multiple joints, with nonabnormal 99mTc-MIBI accumulation. Rheumatology tests were negative. A subsequent bone scintigraphy …

Delayed Diagnosis of Cardiac Amyloidosis Secondary to Multiple Myeloma.

Cardiac amyloidosis is a rare condition with only 2,500 new cases reported yearly in the United States of America (USA). The prognosis of ca … strain patterns suggestive of cardiac amyloidosis and bone marrow biopsy confirmed the diagnosis of multiple myeloma. Unfortunately, despite starting treatment with steroids and chemotherapy, the patient succumbed to his condition in a matter of weeks. We report this case to highlight that cardiac amyloidosis secondary to multiple myeloma can present in the form o …

Assessment of Discordance Among Smoldering Multiple Myeloma Risk Models.

This cohort study assesses the concordance of 3 models to stratify risk for progression to multiple myeloma in an independent cohort of patients with smoldering multiple myeloma.

Case of Kikuchi-Fujimoto disease associated with multiple myeloma.

We present a 47-year-old, South-African origin, woman with a background of stable monoclonal gammopathy of unknown significance (MGUS) who attended A&E with a history of coryzal symptoms associated with persistent fever, lymphadenopathy and a new onset of rash, not responding to antibiotics and paracetamol. A trial of high-dose steroids resolved symptoms. Bone marrow biopsy confirmed a progression of MGUS into multiple myeloma and her axillary lymph node biopsy analysis supported a diagnosis of Kikuchi-Fujimoto disease (KFD). This is an unusual presentation where KFD has been noted alongside M…

Fabry disease associated with multiple myeloma: a case report.

Fabry disease (FD) is an X-linked genetic lysosomal disorder caused by alpha-galactosidase A (GLA) deficiency. Multiple myeloma (MM) predominately affects older adults, which ranks as the second commonest hematological malignancy. Their overlap has rarely been reported. We present a case of the coexistence of FD and MM in a patient. We report the case of a 68-year-old woman who was referred to our hospital for the evaluation of thoracic spine tumor with bone destruction. On admission, her serum creatinine (Cr) level was elevated to 12.70 mg/dL from the baseline value of 0.91 mg/dL. Bone marrow…

Smoldering multiple myeloma: evolving diagnostic criteria and treatment strategies.

The adage for smoldering myeloma (SMM) has been to observe without treatment, until criteria for active multiple myeloma were satisfied. Definitions and risk stratification models have become more sophisticated, with prognostication tailored to include high-risk cytogenetics as per the most recent International Myeloma Working Group 2020 risk model. Moreover, progress in defining genomic evolution and changes in the bone marrow microenvironment through the monoclonal continuum have given insight into the complexities underlying the different patterns of progression observed in SMM. Given recen…

[Research Progress on Prognostic Factors of Multiple Myeloma--Review].

At present, multiple myeloma (MM) still can not be cured, so it is particularly important to study the prognostic factors of MM. Recently, based on the characteristics of tumor or host, the complete disease staging systems, such as Mayor mSMART and frailty scoring system have been updated. Other independent prognostic factors, such as minimal residual disease, circulating tumor DNA, red blood cell distribution width, lymphocyte ratio and thymidine kinase 1 are of great value in evaluating the prognosis of MM from different perspectives. The comprehensive study about these prognostic factors is…
