Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant, clonal plasma cell disorder, characterized by the presence of a monoclonal (M) protein, <10% clonal plasma cells in the bone marrow, and absence of multiple myeloma or related lymphoplasmacytic malignancies (LPMs). In time, myeloma experts decided that the CRAB criteria were not quite enough to define active disease, so they added three more "myeloma defining No calcium abnormalities, no renal function abnormalities, no anemia, and no bone disease. Myeloma cells produce abnormal Key Takeaways: Progression from smoldering multiple myeloma (SMM) to active multiple myeloma (MM) is defined by biomarkers, known as the SLiM criteria (bone marrow infiltration >60%, involved-to-uninvolved serum free light-chain [FLC] ratio of >100, or more than 1 focal lesion of >5 mm as determined by magnetic resonance imaging [MRI]), or by conventional While still considered a pre-malignant condition, its chances of progressing to a malignant plasma cell dyscrasia are generally greater than that for MGUS.

These therapies can help some people with multiple myeloma live disease-free for many years. In some cases, this cancer of the bone marrow never comes back after being treated. However, there are currently no treatments that can guarantee a cure from this disease. When treating cancer, the goal is often to make all signs of disease disappear. Hillengass: The new criteria were published in 2014 by the IMWG, and included not only the old so-called CRAB criteria, which stands for: C for hypercalcemia, R for renal damage, A for anemia, and B for bone disease, which are the 4 major symptoms or complexes of symptoms in multiple myeloma.

If there are symptoms other than CRAB (hypercalcemia, renal dysfunction, anemia, or sclerotic bone lesions, a diagnosis of POEMS syndrome could be considered. For the diagnosis to be multiple myeloma requiring treatment, you would have to meet one of the "CRAB" criteria -- high Calcium levels, Renal (kidney) damage, Anemia, or Bone damage -- or you would have to have one of the three "myeloma defining events": 1. The updated IMWG criteria for diagnosis of multiple myeloma are given in the panel;the supporting data for each of the changes are discussed below. The term multiple myeloma refers to multiple myeloma requiring therapy. Bone marrow plasma cells of 60% or greater In 2014, the International Myeloma Working Group changed the diagnostic criteria for multiple myeloma to include biomarkers. These criteria are referred to by the acronym CRAB, a mnemonic aid covering four features that are associated with end-organ damage linked to myeloma progression. These are calcium elevation, renal insufficiency, anemia, and bone A delay in application of the label of multiple myeloma and postponement of therapy could be detrimental to these patients.

They are an important tool that doctors use to help diagnose multiple myeloma and determine its Myeloma-Defining Events The diagnosis of MM requires 10% or more clonal plasma cells on bone marrow examination or a biopsy-proven plasmacytoma plus the presence of one or more myeloma-defining events.10 Myeloma-defining events in-clude the presence of one or more CRAB features, or one or more biomarkers of malignancy. The CRAB criteria consist of end-organ damage with hypercalcaemia, renal dysfunction, anaemia and bone involvement.The CRAB criteria are not pathognomonic of Generally, the definition of relapse in multiple myeloma is the reappearance of signs and symptoms of a disease after a period of improvement. The myeloma cells are usually only found inside the bone marrow. Minimal criteria for the diagnosis of multiple Multiple myeloma, also known as plasma cell myeloma, is a multifocal proliferation of plasma cells based in the bone marrow. These changes are based on This is defined as a serum calcium level greater than 0.25 mmol/L above the upper limit of normal or a level that is greater than 2.75 mmol/L. The classic definition of multiple myeloma required a clonal proliferation of plasma cells with evidence of end-organ damage.
