The type of treatment, and when it should start, depends on a number of factors. But, supportive care— adjunctive treatment—is an important part of the overall treatment for all patients. Treatment options The treatment options in Part 4 are grouped by the extent of the cancer and severity of its symptoms. A solitary plasmacytoma is when there is only one mass of myeloma cells. Multiple myeloma is when myeloma cells are found in many sites throughout the bone marrow. Multiple myeloma is divided into two main groups. The number of abnormal plasma cells—myeloma cells—in the bone marrow is a key factor used to define these groups. But, other factors are also important. Smoldering (asymptomatic) myeloma is defined as having: † † Presence of M-protein in the blood or † † An increased level of light chains (Bence Jones protein) in the urine and/or † † 10% to 59% abnormal plasma cells in the bone marrow—when 10 to 59 out of every 100 cells in the bone marrow are plasma cells and † † No other myeloma symptoms such as kidney damage, bone damage, anemia, or increased levels of calcium in the blood or features of active myeloma as shown below Active (symptomatic) myeloma is defined as having: † † At least 10% abnormal plasma cells in the bone marrow or a plasmacytoma confirmed by biopsy and † † One or more of the following myeloma-defining events: • At least 60% abnormal plasma cells in the bone marrow—60 or more cells out of every 100 cells in the bone marrow are plasma cells • An increased level of calcium in the blood • Kidney damage • A low number of red blood cells (anemia) • One or more sites of lesions found on imaging tests • A serum free light chain ratio of ≥100
