Multiple myeloma

Multiple myeloma (also known simply as myeloma or 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. Although it initially develops in the bone marrow, it spreads to the peripheral blood, lymph nodes and other organs. Its prognosis despite therapy is generally poor, and treatment may involve chemotherapy and bone marrow transplant.

Epidemiology

There are approximately 45,000 people in the United States living with multiple myeloma, and the American Cancer Society estimates that approximately 14,600 new cases of myeloma are diagnosed each year in the United States. It follows from here that the median prognosis is about three years{{mn|Kyle|1}}.

Multiple myeloma is the second most prevalent blood cancer (10%) after non-Hodgkin's lymphoma. It represents approximately 1% of all cancers and 2% of all cancer deaths. Although the peak age of onset of multiple myeloma is 65 to 70 years of age, recent statistics indicate both increasing incidence and earlier age of onset.

Multiple myeloma affects slightly more men than women. African Americans and Native Pacific Islanders have the highest reported incidence of this disease and Asians the lowest. Results of a recent study found the incidence of myeloma to be 9.5 cases per 100,000 African Americans and 4.1 cases per 100,000 Caucasian Americans. Among African Americans, myeloma is one of the top 10 leading causes of cancer death.
