1 Multiple Myeloma Joan Bladé Asunción, 8 de julio de 2011

2 MONOCLONAL GAMMOPATHIES I. MALIGNANT 1. Multiple myeloma 2. Variants of myeloma Smoldering myeloma Non-secretor Plasma cell leukemia POEMS 3. Localized plasmacytomas Solitary plasmacytoma (bone) Extramedullary plasmacytoma 4. Waldenström’s macroglobulinemia 5. Primary amyloidosis II. NON-MALIGNANT 1. Monoclonal gammopathy of undetermined significance 2. Transient MG: HIV infection, bone marrow trasplant, organ trasplant (liver, kidney)

3 Monoclonal Gammopathy of Undetermined Significance (MGUS) Diagnostic Criteria* Serum M protein size <3g/dL Bone marrow plasma cells <10% No clinical manifestations or other laboratory abnormalities attributable to the monoclonal gammopathy The International Myeloma Working Group. Br J Haematol 2003; 121:

5 Malignant Transformation of MGUS Actuarial probability: 1% per year (30% at 25 yrs) Actual probability (considering competing causes of death): 11% at 25 yrs

6 Factors Predicting Malignant Transformation in MGUS  M-protein size  IgA type  Abnormal free-light chain ratio  Aberrant phenotype (>95%)  “Evolving” vs “Non-evolving”

7 MGUS. Predictors of Malignant Transformation FeatureRR 95% Confidence Interval p-value Evolving vs non-evolving < IgA vs others M-protein (≥15 g/L)

8 Evolving vs. Non-evolving MGUS Evolving Non-evolving

9 MGUS Serum Free Light Chain (FLC) Ratio: an Independent Risk Factor for Progression Risk at 20 years HIGH-RISK Abnormal FLC ratio, non-IgG and M-protein  15g/L 58% LOW-RISK Normal FLC ratio, IgG-type and M-protein <15 g/L 5% Rajkumar et al. Haematologica / The Hematology Journal 2005; S1: 194. Rajkumar et al. Blood 2005; 106:

10 Smoldering Multiple Myeloma (Asymptomatic Myeloma)

11 Smoldering Multiple Myeloma (Asymptomatic Myeloma) Diagnostic Criteria*  Serum M protein size ≥3g/dL and/or urine light chain ≥1g/24 hours and/or bone marrow clonal plasma cells ≥10%  No related organ tissue impairment (no end organ damage including bone lesions) or symptoms * The International Myeloma Working Group. Br J Haematol 2003; 121:

15 SMM: Factors Predicting Progression  M-protein size ≥ 30 g/L and ≥10% BMPC  Abnormal free-light chain ratio  Aberrant phenotype (>95%)  Pattern of MRI  “Evolving” vs “Non-evolving”

16 Symptomatic Multiple Myeloma

17 Symptomatic Multiple Myeloma* M-protein in serum and / or urine Bone marrow (clonal) plasma cells or plasmacytoma** Related organ or tissue impairment (end organ damage, including bone lesions) *Some patients may have no symptoms but have related organ or tissue impairment **If flow cytometry is performed, most plasma cells (>90%) will show a “neoplastic” phenotype

18 Myeloma-related organ or tissue impairment (end organ damage) (ROTI) due to the plasma cell proliferative process Increased serum Calcium Renal insufficciency Anaemia: haemoglobin 2 g/dL below the lower normal limit Bone lesions: lytic lesions or osteoporosis with compression fractures (MRI or CT may clarify) Other: symptomatic hyperviscosity (rare), amyloidosis, recurrent bacterial infecitons (≥ episodes in 12 months), extramedullary plasmacytomas. CRAB (calcium, renal insufficiency, anaemia or bone lesions)
