Multiple myeloma is a malignant blood disorder , constitute about 10 % of all blood Cancer , in which there is unnatural multiplication of plasma cells.(1)B lymphocyte are precursor of plasma cell and their character is in providing immunity by the production of Ig . Therefore , in multiple myeloma , there is overrun of abnormal immunoglobulins ( IgA , IgG and IgM ) and brightness chains . Multiple myeloma has elevated levels of M proteins ( myeloma proteins ) in serum .
How Many Stages Of Multiple Myeloma Cancer Are There?
theatrical production of a disease is done to evaluate the development of cancer and to determine the prognosis of the disease . Multiple myeloma has two staging systems , namely , outside scaffolding system(2)and Durie - Salmon staging system(3 ) . outside staging arrangement ( ISS ) is the more rough-cut and widely used staging for multiple myeloma .
International Staging System
Durie-Salmon Staging System
The three stages in Durie - Salmon theatrical production system is sub - divide into A and B in which A represents normal nephritic function ( serum creatinine < 177 umol / l ) and B represents unnatural renal occasion ( serum creatinine > 177 umol / l ) .
Other prognostic factors that help oneself in determining the survival of the affected role include valuate cytogenetic abnormalities by Pisces test . Additionally , other factors such as advanced age , high LDH and CRP , wretched operation condition , low platelets , M protein ( for instance IgD having morerenal failureandamyloidosis ) , BM plasma cells > 50 % , diffuse plasma cells , serum FLC ratio ( < 0.03 or > 32 ) and in high spirits BM plasma cell labeling index ( PCLI > 3 % ) . The above factors are significant for poorer prognosis and decreased survival of the fittest pace .
Multiple myeloma is mostly a disease of the elderly , with a medial age of occurrence between 65 - 70 years . Multiple myeloma is almost always preceded by premalignant monoclonal antibody gammopathy of undetermined significance ( MGUS ) degree . MGUS is seen in close to 3 % of adults over 50 years of eld , which get on to multiple myeloma in 1 % pillow slip every year . Multiple myeloma can also have an asymptomatic stage known as smoulder multiple myeloma , which has a risk of transmutation of about 10 % per year for the first 5 years .
The most mutual presenting symptom of multiple myeloma arebone pain(in about 60 % cases ) , fatigue duty ( in 30 % cases),weight loss(in 25 % cases),paresthesias(in 5 % casing ) , weakness , infections ( pneumococcus , hemophilus , escherichia),fever , lymphadenopathy , hepatomegaly , splenomegaly , hyperviscosityand spinal compression . Cardiac involvement and tegument lesion may be seen in amyloid deposition .
Diagnosis Of Multiple Myeloma
The diagnosing of multiple myeloma is based on the signs of CRAB ( hypercalcaemia , renal insufficiency , anemia , bony lesion ) in patient who are positive for M protein / light chains and clonal plasm cell with expulsion of other related disorders , such as MGUS , smoldering myeloma , lone plasmacytomas , elemental amyloidosis , Waldenstrom ’s macroglobulinemia , POEMS ( polyneuropathy , organomegaly , endocrinopathies with exclusion of DM and hypothyroidism , monoclonal protein and peel changes ) , and plasm cell leukemia .
To be diagnosed with multiple myeloma , serum atomic number 20 grade should be > 2.875 mmol / l , serum creatinine levels > 177 umol / l , Hb levels < 10 GB / dl or 2 constant of gravitation / dl below normal and lytic bone lesions with severe osteopenia should be present .
