 Multiple myeloma - Wikipedia, the free encyclopedia
Multiple myeloma (also known as MM, myeloma, plasma cell myeloma, or as Kahler's disease after Otto Kahler) is a presently incurable hematological malignancy of plasma cells, the cells of the immune system that produce antibodies.
Additional findings are: a raised calcium (when myeloma cells are breaking down bone, releasing calcium into the bloodstream) and decreased renal function, which may be due to paraprotein deposition in the kidney).
Myeloma deposits appear as "lytic lesions" (with local disappearance of normal bone due to resorption), and on the skull X-ray as "punched-out lesions".

 BestDoctors.com: Condition Summary: Multiple Myeloma   (Site not responding. Last check: 2007-10-21)
Myeloma arises in the bone marrow of patients when a single cell or clone of plasma cells begins to grow uncontrollably and produce an overabundance of one type of antibody or monoclonal antibody.
The cause or causes of myeloma are unknown.
The characteristic hallmark of myeloma is the overproduction of the monoclonal antibody or protein; however, not all individuals with a monoclonal antibody have myeloma.

 Definition
Myeloma cells are identical and produce the same immunoglobulin protein, called monoclonal (M) protein or paraprotein, in large quantities.
Myeloma is often referred to by the particular type of immunoglobulin or light chain (kappa or lambda type) produced by the cancerous plasma cell.
Because the peak age for multiple myeloma is among the elderly it is thought that susceptibility may increase with the aging process and the consequent reduction in immune surveillance of evolving cancer, or that myeloma may result from a lifelong accumulation of toxic insults or antigenic challenges.

Osteolytic lesions are caused by the rapid growth of myeloma cells, which push aside normal bone-forming cells, preventing them from repairing general wear and tear of the bones.  Under normal circumstances, cells called osteoclasts destroy dead and dying bone.

 Knowing Your Treatment Options
Treatment of myeloma can be a complex process because many variables must be taken into account, such as the patient's overall state of health, other medical issues/diseases, and how well the disease is currently controlled, as well as the type, number, and response to previous therapy.
Some myeloma groups consider a decrease in M protein between 25% and 50% to be a minimal response whereas others consider this to be stable disease.
Progressive disease refers to active myeloma that is worsening (ie, increasing M protein and worsening organ or tissue impairment [end organ damage]).
