Consensus in the Management of Multiple Myeloma in India at Myeloma State of the Art 2016 Conference.

The science of multiple myeloma (MM) and related plasma cell disorders is rapidly evolving with increased understanding of the disease biology and recent approval of the newer drugs widening the therapeutic armamentarium. Despite multiple international guidelines regarding the management of this disease, the practice of managing MM is not uniform amongst Indian physicians. There are challenges in management which are unique to the Indian patients. This review discusses these challenges and the consensus of the nation-wide experts in dealing with the same. We also briefly highlighted the perspe…

Differences in the distribution of cytogenetic subtypes between multiple myeloma patients with and without a family history of monoclonal gammopathy and multiple myeloma.

We previously reported an increased risk of monoclonal gammopathy of undetermined significance (MGUS) in first-degree relatives of MGUS and multiple myeloma patients. Here, we examine whether primary cytogenetic categories of myeloma differ between patients with and without a family history of MGUS or myeloma. We studied 201 myeloma patients with available data on family history and molecular cytogenetic classification. Myeloma with trisomies was more common in probands who had an affected first-degree relative with MGUS or myeloma compared with those without a family history (46.9% vs. 33.5%,…

Руководящие принципы и консенсус в отношении минимально адаптированной к остаточным болезням терапии в множестве миеломы, выработанные Рабочей группой по миеломе в Пантихоокеанском регионе.

Лечение множественной миеломы (ММ) вступило в эру терапии, ориентированной на глубокую ремиссию, где минимальные остаточные заболевания (МВД) стали ключевым показателем реакции на лечение и долгосрочного прогнозирования, превосходя обычные критерии полной ремиссии. Однако оптимальная интеграция МРТ в процесс принятия клинических решений еще не достигнута. Этот экспертный консенсус предлагает основанные на фактических данных руководящие указания относительно пересмотра целей лечения в эпоху лечения на основе CD38, включения статуса MRD в терапевтические решения, стандартизации обнаружения MRD и…

[A rare case of multiple myeloma: multiple solitary plasmacytomas of distal extremities].

This article describes a case of 68-years-old male with very atypic variation of multiple myeloma occuring as multifocal osteolysis limited to tibiae, cuboid bone, radius and ulna, in the absence of diffuse bone marrow infiltration. The main goal of this article is to point out the importance of permanent awareness during diagnostics and treatment of this insidious disease.

In vivo and in silico studies on single versus multiple transplants for multiple myeloma.

High-dose therapy and autologous stem cell transplantation (HDT-ASCT) have significantly improved survival in multiple myeloma (MM). However, patients are not cured, responses are variable and only about 40% of patients achieve a complete response (CR). Optimal timing of the procedure and knowledge of the relapse kinetics may assist physicians when they consider this therapeutic modality for their patients. We analyzed myeloma tumor burden and kinetics before and after HDT-ASCT in a cohort of 265 patients. Disease burden was estimated from serial M-spike measurements and the data fitted to the…

[Plasmacytoma with multiple hypervascular lesions revealed by angiography in a patient with multiple myeloma].

A 68-year-old woman suffering from a left iliac tumor and severe back pain was admitted to another hospital in May 1999. The bone X-ray, CT … in in the serum and urine, but the patient was diagnosed as having a non-secretory or low producing multiple myeloma because of the presence of 42.8% of abnormal plasma cells in the bone marrow aspirate. Her symptoms improved following 3 courses of MCNU-VMP therapy and the bone marrow plasma cells decreased to less than 5%. She was discharged and treated as an out …

Multiple Liver Nodules Mimicking Metastatic Disease as Initial Presentation of Multiple Myeloma.

Multiple myeloma is a malignant clonal proliferation of plasma cells in the bone marrow preceded by monoclonal gammopathy of undetermined significance. Initial presentation of multiple myeloma as extramedullary spread in soft tissues particularly in the liver is uncommon. We report a case of a 74-year-old African American female who presented with epigastric pain, hematemesis, elevated alkaline phosphatase, and gamma-glutamyl transferase. Initial impression was peptic ulcer disease; however, ultrasound and CT scan of the abdomen showed multiple liver nodules and perihepatic lymphadenopathy sug…

Multiple Facets of Multiple Myeloma in Kidney Biopsy: A Multicenter Retrospective Study.

INTRODUCTION: Multiple myeloma is a type of plasma cell dyscrasia, which causes clonal proliferation of plasma cells and deposition in various organ systems. At presentation, 50% of patients with multiple myeloma have kidney dysfunction, which is considered a poor prognostic indicator. Data on the histopathological manifestations of multiple myeloma are sparse. OBJECTIVE: To look at the kidney histopathological lesions in patients with the clinical diagnosis of multiple myeloma. MATERIALS AND METHODS: A retrospective analysis of all kidney biopsies in patients with the clinical diagnosis of …

A NOTCH3-CXCL12-driven myeloma-tumor niche signaling axis promotes chemoresistance in multiple myeloma.

Multiple myeloma (MM) remains incurable due to disease relapse and drug resistance. Notch signals from the tumor microenvironment (TME) confer chemoresistance, but the cellular and molecular mechanisms are not entirely understood. Using clinical and transcriptomic datasets, we found that NOTCH3 is upregulated in CD138+ cells from newly diagnosed MM (NDMM) patients compared to healthy individuals and increased in progression/relapsed MM (PRMM) patients. Further, NDMM patients with high NOTCH3 expression exhibited worse responses to bortezomib (BOR)-based therapies. Cells of the TME, including o…

Management of multiple myeloma-related renal impairment: recommendations from the International Myeloma Working Group.

Here, the International Myeloma Working Group (IMWG) updates its clinical practice recommendations for the management of multiple myeloma-related renal impairment on the basis of data published until Dec 31, 2022. All patients with multiple myeloma and renal impairment should have serum creatinine, estimated glomerular filtration rate, and free light chains (FLCs) measurements together with 24-h urine total protein, electrophoresis, and immunofixation. If non-selective proteinuria (mainly albuminuria) or involved serum FLCs value less than 500 mg/L is detected, then a renal biopsy is needed. T…

International Myeloma Working Group recommendations for the treatment of multiple myeloma-related bone disease.

PURPOSE: The aim of the International Myeloma Working Group was to develop practice recommendations for the management of multiple myeloma (MM) -related bone disease. METHODOLOGY: An interdisciplinary panel of clinical experts on MM and myeloma bone disease developed recommendations based on published data through August 2012. Expert consensus was used to propose additional recommendations in situations where there were insufficient published data. Levels of evidence and grades of recommendations were assigned and approved by panel members. RECOMMENDATIONS: Bisphosphonates (BPs) should be co…

Measurement of health-related quality of life in multiple myeloma. Nordic Myeloma Study Group.

When a randomized trial (NMSG 4/90) comparing treatment with melphalan/prednisone to melphalan/ prednisone + interferon alpha-2b in newly diagnosed multiple myeloma was initiated in 1990, a quality-of-life assessment was integrated into the study. We used the questionnaire (QLQ-C30) developed by the European Organization of Research and Treatment of Cancer (EORTC) Study Group on Quality of Life. The QLQ-C30 incorporates five functional scales, three symptom scales, a global health and quality-of life scale and some single symptom measures. The questionnaire was completed prior to treatment and…

Lenalidomide based triplets in relapsed/refractory multiple myeloma: analysis of the Czech Myeloma Group.

Despite significant advancements in therapy of multiple myeloma (MM) over the past 20 years, most patients experience relapse, necessitating new treatment approaches. This study aims to compare the real-world effectiveness of lenalidomide (LEN)-based triplet therapies, specifically daratumumab (DRD), carfilzomib (KRD), and ixazomib (IRD), in relapsed/refractory multiple myeloma (RRMM).A retrospective registry-based study analyzed 538 RRMM patients undergoing therapy for their first to third relapse. The primary endpoints were overall response rate (ORR), progression-free survival (PFS), and ov…

Autologous stem cell transplantation for multiple myeloma patients whose myeloma-defining event was SLiM.

In 2014, the International Myeloma Working Group (IMWG) updated the criteria for diagnosing myeloma and added three additional criteria to the traditional Calcium elevation, Renal impairment, Anemia, Bone disease (CRAB) criteria, called the Sixty % marrow plama cells, Light chain ratio >60, Mri demonstates lytic lesions (SLiM) criteria (clonal bone marrow plasma cells ≥60%, involved to uninvolved free light chain ratio (FLCr) ≥100 and >1 focal lesion on magnetic resonance imaging (MRI)). We report on the outcomes of 30 patients who underwent autologous stem cell transplantation (ASCT) where th
