Objectives:
1. Describe common presenting features and criteria for diagnosis and management of Multiple Myeloma.
2. Identify the latest clinical laboratory tests, cytogenetics and clinicopathologic abnormalities associated with multiple myeloma.
3. Recognize the different types of amyloidosis with different prognoses and treatment options.

Plasma Cells vs. Myeloma Cells
Myeloma cells can be distinguished from normal plasma cells by the presence of nucleoli, very large nuclei, irregular nuclear contours and multinucleation.

Pathophysiology of Myeloma
• Multiple organs and body systems affected
• Hallmarks:
•Anemia
•Renal failure
•Bone destruction (lytic bone lesions)
•Hypercalcemia
•Presence of monoclonal protein
• Increased risk of infection

Pathobiology- What is Myeloma?
• Plasma cell malignancy characterized by production of abnormal immunoglobulin
• 3 different types
• Protein in serum
• Protein in urine
• Non-secretory

Plasmacytomas
Jagannath S, 2004

Skeletal Involvement
• Pathobiology: malignant cells produce osteoclast- activating factors that destroy bone cells and lead to extensive osteolysis, severe bone pain, and pathologic fractures
• Lumbar/thoracic vertebrae most commonly involved
• Ribs/skull/pelvis/proximal long bones frequently involved
• Spinal cord compression

Treatment of MM – ASH 2009: Recent and Ongoing Clinical Studies
• Transplant-ineligible patients
• VMP – VT vs.. VTP – VP (maintenance improves response)
• VMPT – VT vs.. VMP (weekly velcade = decreased neuropathy)
• MP vs.. MPT
• MP vs.. MPR vs.. MPR (Lenalidomide maintenance)
• Transplant-eligible patients• Lenalidomide after ASCT (lenalidomide maintenance)
Patient Treatment Largely Determined by Transplant Eligibility

Amyloidosis – Overview
• Amyloidosis: extracellular tissue deposition of fibrils
• Composed of low molecular weight subunits (most of which are in the molecular weight range of 5 to 25 kD) of a variety of proteins
• These proteins often circulate as constituents of plasma.
• Hereditary and non hereditary types
• Patients with MM can have amyloidosis concurrently

Amyloidosis Classification
• AL amyloid - deposition of protein derived from Ig light chain fragments (usually lambda)
- Detectable M protein in serum or urine
- Accounts for approx 80%.
• AA amyloid – chronic inflammatory states (i.e. RA or spondyloarthropathy)
- Fibrils are composed of fragments of the acute phase reactant - serum amyloid A (SAA) protein
•Gertz, M. A. (2010).•Kyle, R. A. (2001).

Amyloidosis Classification
• Hemodialysis-Associated Amyloidosis
• Deposition of fibrils derived from B2M
• Accumulates in patients with end-stage renal disease being maintained for prolonged periods on dialysis
• Cannot pass through dialysis filters
• Predilection for osteoarticular structures (synovium, tendons sheaths, and joints)
•Drueke, T. M. (2000)

Amyloidosis Classification
• Senile Systemic Amyloidosis — Deposition of transthyretin in myocardium and other sites
- Compared to patients with AL amyloidosis, those with the senile systemic disease survive longer (75 vs. 11 mos) despite having ventricular free wall and septal thickening due to amyloid deposits
- Significant renal involvement is rare
• Organ-Specific Amyloid (aka Localized Amyloidosis)
- Amyloid deposition isolated to a single organ, such as the skin, eye, heart, tongue, urinary bladder, lung and larynx.
- Frequent infiltrates of lymphocytes and plasma cells at periphery
- AL protein identified in some cases
Kyle, R. A. (2001)

Primary (AL) Amyloidosis and Light and Heavy Chain Deposition Diseases
• Amyloidosis results from clonal plasma cell proliferative disorders
• Characterized by tissue deposits of light chain or heavy chain fragments
• Leading to organ dysfunction such as heart or renal failure, GI blood loss, or disruption of nerve endings

Primary (AL) Amyloidosis and Light and Heavy Chain Deposition Diseases
• Amyloid fibrils – abnormal folding of proteins into cross-β-pleated sheets which are deposited extracellularly in various organs.
- Immunoglobulin (Ig) light chains (usually lambda)
- Can be identified by their characteristic appearance on electron microscopy
- Congo red (“apple green” birefringence with polarized light)
- Thioflavin T (producing an intense yellow-green fluorescence).
- Weakly stain with periodic acid Schiff's (PAS)
- Immunostains: amyloid PKyle, R. A. (2001)Gertz, M. A. (2010)

Primary (AL) Amyloidosis and Light and Heavy Chain Deposition Diseases
• Neuro – Sensorimotor changes, Peripheral neuropathy
• GI- Hepatomegaly, gastroparesis, malabsorption, obstruction
• MSK- amyloid arthropathy, ‘shoulder pad sign’
• Pulm- pleural effusions, CHF sxs if cardiac involvement
• Derm- waxy thickening, ecchymoses, purpura in a periorbital distribution, ‘raccoon eyes’ , and subcutaneous nodules or plaques

Dx of Primary (AL) Amyloidosis- Cardiomyopathy
• Cardiac manifestations may be absent, minor
- In 1/3rd of patients, disease manifested by cardiac events
- Most common ECG abnormality in cardiac amyloidosis is low voltage in the limb leads (50%)
- ECHO may show LV wall thickening with evidence of diastolic dysfunction , granular, “sparkling” appearance of the myocardium, IVS thickness in more advanced disease
- Cardiac MRI - global and subendocardial late enhancement of the myocardium
- Endomyocardial bx definitive dx
- OS 6-9 mos if heart failure > yrs with tx

Dx of Primary (AL) Amyloidosis- Renal
• Proteinuria - may be severe enough to cause nephrotic syndrome
• Diffuse glomerular deposition of amorphous hyaline material, initially in the mesangium –With time mesangial deposits and
deposits along the basement membranes lead to capillary narrowing and obliteration
–Amyloid deposits also may be seen in the small arteries, arterioles, and tubular basement membranes.

Dx of Primary (AL) Amyloidosis- Renal
• Immunofluorescence microscopy is negative for immunoglobulins and complement in secondary AA, but is typically positive for monoclonal lambda or kappa light chains in the primary form
• The amount of monoclonal protein in the beta/gamma region of patients w/ MM but albuminuria and nephrotic range proteinuria
• Elevated B2M, Hypoalbuminemia

Dx and Monitoring of Primary (AL) Amyloidosis
• Some have systemic MM as well as AL amyloid
• SPEP, UPEP
• β2M
• CBC diff, CMP, ALB
• Monoclonal protein, blood and urine
• 24 hr urine for Protein
• Skeletal survey to r/o lesions
• High Sensitivity TNT assay – improves detection of cardiac involvement and powerful diagnostic determinant
• Serum Free Light Chain Assay – more sensitive for organ response
• Echocardiography, Fat-Pad Aspirate ‘Congo Red Stain’

Treatment of Amyloidosis- AL and AA
• Treat to prevent renal complications - i.e. Steroids such as dexamethasone, melphalan,
cyclophosphamide or lenalidomide- Clin trials with transplant, bortezomib and
lenalidomide
• Secondary AA can lead to renal failure d/t high circulating levels of Serum Amyloid A- Treatment aim is to control primary disease, such as
RA, Chron’s disease, - Colchicine in Familial Mediterranean fever (FMF)

Summary
• MM and PCDs are incurable, chronic diseases
• Palliation of symptoms and prevention of organ damage is essential to patient quality of life
• Novel agents have demonstrated significant activity in relapsed/refractory MM and amyloidosis and shown improved survival
• Sequential administration of novel therapies can potentially prolong survival
