| '''Waldenström macroglobulinemia''' (WM) is cancer involving a subtype of white blood cells called [[lymphocytes]]. The main attributing antibody is IgM. It is a type of [[lymphoproliferative disease]], and shares clinical characteristics with the indolent [[non-Hodgkin lymphoma]]s.<ref name="Cheson">{{cite book | author = Cheson BD | year = 2006 | title = ACP Medicine | chapter = Chronic Lymphoid Leukemias and Plasma Cell Disorders | editor = Dale DD, Federman DD | publisher = WebMD Professional Publishing | location = New York, NY | id = ISBN 0974832715 }}</ref> | | {{CMG}}; {{AE}} {{S.M.}}, {{RAK}}, {{MGS}}; {{GRR}} {{Nat}} |
| ==Historical Perspective==
| |
|
| |
|
| WM was first described by [[Jan G. Waldenström]] (1906-1996) in 1944 in two patients with bleeding from the nose and mouth, [[anemia]], decreased levels of [[fibrinogen]] in the blood (hypofibrinogenemia), [[lymphadenopathy|swollen lymph nodes]], neoplastic plasma cells in bone marrow, and increased [[viscosity]] of the blood due to increased levels of a class of heavy proteins called [[macroglobulins]].<ref name="Waldenstrom1944">{{cite journal | author= Waldenstrom J | title=Incipient myelomatosis or "essential" hyperglobulinemia with fibrinognenopenia-a new syndrome? | journal=Acta Med Scand| year=1944 | pages=216-247 | volume=117}} </ref> | | {{SK}} Waldenstrom/Waldenstrom's macroglubulinemia (WM), Primary [[macroglobulinemia]], [[Lymphoplasmacytic lymphoma]] (LPL), [[Plasmacytoid]] [[lymphocytic lymphoma]], [[Familial]] Waldenstrom's Macroglobulinaemia, Waldenström macroglobulinaemia |
|
| |
|
| For a period of time, WM was considered to be related to [[multiple myeloma]] due to the presence of monoclonal gammopathy and infiltration of the bone marrow and other organs by plasmacytoid lymphocytes. The new [[World Health Organization]] (WHO) classification, however, places WM under the category of lymphoplasmacytic lymphomas, itself a subcategory of the indolent (low-grade) non-Hodgkin lymphomas. <ref name="Harris">{{cite journal | author=Harris NL, Jaffe ES, Diebold J, Flandrin G, Muller-Hermelink HK, Vardiman J, Lister TA, Bloomfield CD | title=The World Health Organization classification of neoplastic diseases of the haematopoietic and lymphoid tissues: Report of the Clinical Advisory Committee Meeting, Airlie House, Virginia, November 1997 | journal=Histopathology | year=2000 | pages=69-86 | volume=36 | issue=1 | id=PMID 10632755}}</ref>

| ===Laboratory Tests=== | | ==[[Waldenström's macroglobulinemia causes|Causes]]== |
|
| |
|
| *The laboratory diagnosis of Waldenström's macroglobulinemia is contingent on demonstrating a significant monoclonal [[IgM]] spike and identifying malignant cells consistent with Waldenström's macroglobulinemia (usually found in bone marrow biopsy samples and aspirates).
| | ==[[Waldenström's macroglobulinemia differential diagnosis|Differentiating Waldenström's Macroglobulinemia from other Diseases]]== |
|
| |
|
| *General studies include a [[CBC]], red cell indices, [[platelet count]], and a [[peripheral smear]].
| | ==[[Waldenström's macroglobulinemia epidemiology and demographics|Epidemiology and Demographics]]== |
|
| |
|
| *[[Normocytic normochromic anemia]], [[leukopenia]], and [[thrombocytopenia]] may be observed. [[Anemia]] is the most common finding, present in 80% of patients with symptomatic Waldenström's macroglobulinemia.
| | ==[[Waldenström's macroglobulinemia risk factors|Risk Factors]]== |
|
| |
|
| *The [[peripheral smear]] may reveal plasmacytoid [[lymphocyte]]s, normocytic normochromic red cells, and rouleaux formation.
| | ==[[Waldenström's macroglobulinemia screening|Screening]]== |
|
| |
|
| *[[Neutropenia]] can be found in some patients.
| | ==[[Waldenström's macroglobulinemia natural history, complications and prognosis|Natural History, Complications and Prognosis]]== |
|
| |
|
| *[[Thrombocytopenia]] is found in approximately 50% of patients with bleeding diathesis.
| | ==[[Diagnosis]]== |
| | | [[Waldenström's macroglobulinemia diagnostic study of choice|Diagnostic Study of Choice]] | [[Waldenström's macroglobulinemia history and symptoms|History and Symptoms]] | [[Waldenström's macroglobulinemia physical examination|Physical Examination]] | [[Waldenström's macroglobulinemia laboratory findings|Laboratory Findings]] | [[Waldenström's macroglobulinemia electrocardiogram|Electrocardiogram]] | [[Waldenström's macroglobulinemia chest x ray|Chest X Ray]] | [[Waldenström's macroglobulinemia CT|CT]] | [[Waldenström's macroglobulinemia MRI|MRI]] | [[Waldenström's macroglobulinemia Electrocardiography or Ultrasound|Electrocardiography or Ultrasound]] | [[Waldenström's macroglobulinemia PET|PET]] | [[Waldenström's macroglobulinemia Other Diagnostic Studies|Other Diagnostic Studies]] |
| *Chemistry tests include [[lactate dehydrogenase]] ([[LDH]]) levels, [[uric acid]] levels, [[erythrocyte sedimentation rate]] ([[ESR]]), renal and [[hepatic function test]]s, [[total protein]] levels, and an [[albumin-to-globulin ratio]]. The [[ESR]] and [[uric acid]] level may be elevated.
| |
| | |
| *[[Creatinine]] is occasionally elevated and electrolytes are occasionally abnormal. [[Hypercalcemia]] is noted in approximately 4% of patients.
| |
| | |
| *The [[LDH]] level is frequently elevated, indicating the extent of Waldenström's macroglobulinemia–related tissue involvement.
| |
| | |
| *[[Rheumatoid factor]], [[cryoglobulin]]s, [[direct antiglobulin test]] and [[cold agglutinin titre]] results can be positive.
| |
| | |
| *Beta-2-microglobulin and [[C-reactive protein]] test results are not specific for Waldenström's macroglobulinemia. Beta-2-microglobulin is elevated in proportion to tumor mass.
| |
| | |
| *Coagulation abnormalities may be present. Prothrombin time, activated partial thromboplastin time, thrombin time, and fibrinogen tests should be performed. Platelet aggregation studies are optional.
| |
| | |
| *Serum [[protein electrophoresis]] results indicate evidence of a monoclonal spike but cannot establish the spike as IgM. An M component with beta-to-gamma mobility is highly suggestive of Waldenström's macroglobulinemia.
| |
| | |
| * A distinguishing feature of WM is the presence of an [[IgM monoclonal protein]] (or [[paraprotein]]) that is produced by the cancer cells, and a concurrent decrease in levels of uninvolved [[immunoglobulins]] (i.e., [[IgG]] and [[IgA]]).
| |
| | |
| *Immunoelectrophoresis and immunofixation studies help identify the type of immunoglobulin, the clonality of the light chain, and the monoclonality and quantitation of the paraprotein.
| |
| | |
| *High-resolution electrophoresis and serum and urine immunofixation are recommended to help identify and characterize the monoclonal IgM paraprotein.
| |
| | |
| *The light chain of the monoclonal protein is usually the kappa light chain. At times, patients with Waldenström's macroglobulinemia may exhibit more than one M protein.
| |
| | |
| *Plasma viscosity must be measured.
| |
| | |
| *Results from characterization studies of urinary immunoglobulins indicate that light chains ([[Bence Jones protein]]), usually of the kappa type, are found in the urine.
| |
| | |
| *Urine collections should be concentrated.
| |
| | |
| *[[Bence Jones protein|Bence Jones proteinuria]] is observed in approximately 40% of patients and exceeds 1 g/d in approximately 3% of patients.
| |
| | |
| *Patients with findings of [[peripheral neuropathy]] should have nerve conduction studies and [[antimyelin associated glycoprotein]] serology

| There is no single accepted treatment for WM. Indeed, in 1991, Waldenström himself raised the question of the need for effective therapy.<ref>{{cite journal | author=Waldenstrom J | title=To treat or not to treat, this is the real question | journal=Leuk Res | year=1991 | pages=407-8 | volume=15 | issue=6 | id=PMID 1907339}}</ref> In the absence of symptoms, many clinicians will recommend simply monitoring the patient.

| | |
| In 2002, a panel at the International Workshop on Waldenström's Macroglobulinemia agreed on criteria for the initiation of therapy. They recommended starting therapy in patients with constitutional symptoms such as recurrent [[fever]], [[night sweats]], [[fatigue]] due to [[anemia]], [[weight loss]], progressive symptomatic [[lymphadenopathy]] or [[splenomegaly]], and [[anemia]] due to [[bone marrow]] infiltration.
| |
| | |
| Complications such as [[hyperviscosity syndrome]], symptomatic sensorimotor peripheral neuropathy, systemic [[amyloidosis]], [[renal insufficiency]], or symptomatic cryoglobulinemia were also suggested as indications for therapy.<ref name="Kyel2003">{{cite journal | author=Kyle RA, Treon SP, Alexanian R, Barlogie B, Bjorkholm M, Dhodapkar M, Lister TA, Merlini G, Morel P, Stone M, Branagan AR, Leblond V | title=Prognostic markers and criteria to initiate therapy in Waldenstrom's macroglobulinemia: consensus panel recommendations from the Second International Workshop on Waldenstrom's Macroglobulinemia | journal=Semin Oncol | year=2003 | pages=116-20 | volume=30 | issue=2 | id=PMID 12720119}}</ref>

| | |
| Treatment includes the monoclonal antibody [[rituximab]], sometimes in combination with chemotherapeutic drugs such as [[chlorambucil]], [[cyclophosphamide]], or [[vincristine]]. [[Corticosteroid]]s may also be used in combination. [[Plasmapheresis]] can be used to treat the hyperviscosity syndrome by removing the paraprotein from the blood, although it does not address the underlying disease.<ref name="Gertz">{{cite journal | author=Gertz MA | title=Waldenstrom macroglobulinemia: a review of therapy | journal=Am J Hematol | year=2005 | pages=147-57 | volume=79 | issue=2 | id=PMID 15929102}}</ref>
