What tests do health care professionals use to make a diagnosis of multiple myeloma?

In many patients, multiple myeloma is first suspected when a routine blood test shows an abnormal amount of protein in the bloodstream or an unusual stickiness of red blood cells causing them to stack up almost like coins in a pattern called rouleaux, an unusual formation for red blood cells. The health care professional will do a history and physical exam, looking for signs and symptoms (see above) of multiple myeloma. If multiple myeloma is suspected, several studies help confirm the diagnosis. They include a bone marrow aspiration and biopsy most commonly from the large bones of the pelvis. Cells obtained from the marrow are studied by a pathologist to determine if there are abnormal types or numbers of cells. A sample of the bone marrow aspirate is also studied for more detailed characteristics such as the presence or absence of abnormal numbers or types of chromosomes by what is called cytogenetic testing. Other molecular testing may be done on the marrow sample as well. The bone marrow biopsy can assess the concentrations of cells in the marrow and the presence of abnormal invasive growth of cellular elements. Blood testing and urine testing by several methods can determine levels and types of monoclonal protein produced. The M protein may be a complete form of a type of antibody called an immunoglobulin or only a portion of the protein called a light chain. Normal antibodies consist of both heavy and light chain components. In 2011, the National Comprehensive Cancer Network (NCCN) recommended that a serum free light chain assay and fluorescence in situ hybridization (FISH) test be used to further identify multiple myeloma in patients. Most clinicians will use X-ray studies to identify skeletal lesions and MRI for spinal, paraspinal, or spinal cord lesions in multiple myeloma. In addition, several routine tests (CBC, sedimentation rate, BUN, C-reactive protein, and others) are also done.

What types of health care professionals treat multiple myeloma?

Although the patient's primary care doctor helps to manage the patient's care, the specialists involved often include an oncologist, hematology pathologist, radiologist, stem cell transplant specialist, and occasionally a surgeon (orthopedist and/or spine surgeon).
