Role of Magnetic Resonance Imaging in the Management of Patients With Multiple Myeloma: A Consensus Statement

Posted · Add Comment

The IMF’s research division, the International Myeloma Working Group (IMWG), published guidelines in the Journal of Clinical Oncology on the use of MRI (magnetic resonance imaging) in myeloma. The IMWG guidelines recommend that all patients with smoldering or asymptomatic myeloma undergo whole-body MRI, or spine and pelvic MRI if whole body MRI is not available. This recommendation is in sync with the IMWG’s “New Diagnostic Criteria” for myeloma, published in November in the Lancet Oncology, in which the presence of more than one MRI lesion is identified as a basis for considering starting full anti-myeloma therapy. The guidelines note that MRI at diagnosis of symptomatic patients (based upon presence of […]

International Myeloma Working Group updated criteria for the diagnosis of multiple myeloma

Posted · Add Comment

This International Myeloma Working Group consensus updates the disease defi nition of multiple myeloma to include validated biomarkers in addition to existing requirements of attributable CRAB features (hypercalcaemia, renal failure, anaemia, and bone lesions). These changes are based on the identifi cation of biomarkers associated with near inevitable development of CRAB features in patients who would otherwise be regarded as having smouldering multiple myeloma. A delay in application of the label of multiple myeloma and postponement of therapy could be detrimental to these patients. In addition to this change, we clarify and update the underlying laboratory and radiographic variables that fulfi l the criteria for the presence of myeloma-defi ning CRAB features, and the histological and monoclonal […]

International Myeloma Working Group recommendations for global myeloma care

Posted · Add Comment

Recent developments have led to remarkable improvements in the assessment and treatment of patients with multiple myeloma (MM). New technologies have become available to precisely evaluate the biology and extent of the disease, including information about cytogenetics and genetic abnormalities, extramedullary manifestations and minimal residual disease. New, more effective drugs have been introduced into clinical practice, which enable clinicians to significantly improve the outcome of patients but also pose new challenges for the prevention and management of their specific side effects. Given these various new options and challenges, it is important to identify the minimal requirements for diagnosis and treatment of patients, as access to the most sophisticated advances may […]

New drugs and novel mechanisms of action in multiple myeloma in 2013: a report from the International Myeloma Working Group (IMWG)

Posted · Add Comment

Treatment in medical oncology is gradually shifting from the use of nonspecific chemotherapeutic agents toward an era of novel targeted therapy in which drugs and their combinations target specific aspects of the biology of tumor cells. Multiple myeloma (MM) has become one of the best examples in this regard, reflected in the identification of new pathogenic mechanisms, together with the development of novel drugs that are being explored from the preclinical setting to the early phases of clinical development. We review the biological rationale for the use of the most important new agents for treating MM and summarize their clinical activity in an increasingly busy field. First, we discuss data […]

IMWG consensus on risk strati?cation in multiple myeloma

Posted · Add Comment

Multiple myeloma is characterized by underlying clinical and biological heterogeneity, which translates to variable response to treatment and outcome. With the recent increase in treatment armamentarium and the projected further increase in approved therapeutic agents in the coming years, the issue of having some mechanism to dissect this heterogeneity and rationally apply treatment is coming to the fore. A number of robustly validated prognostic markers have been identi?ed and the use of these markers in stratifying patients into different risk groups has been proposed. In this consensus statement, the International Myeloma Working Group propose well-de?ned and easily applicable risk categories based on current available information and suggests the use of […]

International Myeloma Working Group consensus statement for the management, treatment, and supportive care of patients with myeloma not eligible for standard autologous stem-cell transplantation

Posted · Add Comment

PURPOSE: To provide an update on recent advances in the management of patients with multiple myeloma who are not eligible for autologous stem-cell transplantation. METHODS: A comprehensive review of the literature on diagnostic criteria is provided, and treatment options and management of adverse events are summarized. RESULTS: Patients with symptomatic disease and organ damage (ie, hypercalcemia, renal failure, anemia, or bone lesions) require immediate treatment. The International Staging System and chromosomal abnormalities identify high- and standard-risk patients. Proteasome inhibitors, immunomodulatory drugs, corticosteroids, and alkylating agents are the most active agents. The presence of concomitant diseases, frailty, or disability should be assessed and, if present, treated with reduced-dose approaches. Bone disease, […]

Management of multiple myeloma in Asia: resource-stratified guidelines

Posted · Add Comment

Treatment of multiple myeloma has undergone substantial developments in the past 10 years. The introduction of novel drugs has changed the treatment of the disease and substantially improved survival outcomes. Clinical practice guidelines based on evidence have been developed to provide recommendations on standard treatment approaches. However, the guidelines do not take into account resource limitations encountered by developing countries. The huge disparities in economy, health-care infrastructure, and access to novel drugs in Asian countries hinder the delivery of optimum care to every patient with multiple myeloma in Asia. In this Review we outline the guidelines that correspond with different levels of health-care resources and expertise, with the aim to […]

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

Posted · Add Comment

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 considered in all patients with MM receiving first-line antimyeloma therapy, regardless of presence of osteolytic bone lesions on conventional radiography. However, it is unknown if BPs offer any advantage […]

Combining Fluorescent In Situ Hybridization (iFISH) data with ISS staging improves risk assessment in myeloma: an International Myeloma Working Group (IMWG) collaborative project

Posted · Add Comment

The combination of serum b2-microglobulin and albumin levels has been shown to be highly prognostic in myeloma as the International Staging System (ISS). The aim of this study was to assess the independent contributions of ISS stage and cytogenetic abnormalities in predicting outcomes. A retrospective analysis of international studies looking at both ISS and cytogenetic abnormalities was performed in order to assess the potential role of combining ISS stage and cytogenetics to predict survival. This international effort used the International Myeloma Working Group database of 12 137 patients treated worldwide for myeloma at diagnosis, of whom 2309 had cytogenetic studies and 5387 had analyses by ?uorescent in situ hybridization (iFISH).
