Stem cell transplant (Step 1). Blood is taken from a vein in the arm of the donor. The patient or another person may be the donor. The blood flows through a machine that removes the stem cells. Then the blood is returned to the donor through a vein in the other arm.Stem cell transplant (Step 2). The patient receives chemotherapy to kill blood-forming cells. The patient may receive radiation therapy (not shown).Stem cell transplant (Step 3). The patient receives stem cells through a catheter placed into a blood vessel in the chest.

Biologic therapy

Biologic therapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.

Interferon is a type of biologic therapy. It affects the division of cancer cells and can slow tumor growth.

See Drugs Approved for Multiple Myeloma and Other Plasma Cell Neoplasms for more information.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.

Surgery

Surgery to remove the tumor may be done and is usually followed by radiation therapy. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.

Watchful waiting

Watchful waiting is closely monitoring a patient's condition without giving any treatment until symptoms appear or change.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI Web site.

New combinations of therapies

Clinical trials are studying different combinations of biologic therapy, chemotherapy, steroid therapy, and drugs. New treatment regimens using thalidomide or lenalidomide are also being studied.

Supportive care is given to lessen the problems caused by the disease or its treatment.

This therapy controls problems or side effects caused by the disease or its treatment, and improves quality of life. Supportive care is given to treat problems caused by multiple myeloma and other plasma cell neoplasms.

Supportive care may include the following:

  • Plasmapheresis: If the blood becomes thick with extra antibody proteins and interferes with circulation, plasmapheresis is done to remove extra plasma and antibody proteins from the blood. In this procedure blood is removed from the patient and sent through a machine that separates the plasma (the liquid part of the blood) from the blood cells. The patient's plasma contains the unneeded antibodies and is not returned to the patient. The normal blood cells are returned to the bloodstream along with donated plasma or a plasma replacement. Plasmapheresis does not keep new antibodies from forming.
  • High-dose chemotherapy with stem cell transplant: If amyloidosis occurs, treatment may include a clinical trial of high-dose chemotherapy followed by stem cell transplant using the patient's own stem cells.
  • Radiation therapy: Radiation therapy is given for bone lesions of the spine.
  • Chemotherapy: Chemotherapy is given to reduce back pain from osteoporosis or compression fractures of the spine.
  • Bisphosphonate therapy: Bisphosphonate therapy is given to slow bone loss and reduce bone pain. See the following PDQ summaries for more information on bisphosphonates and problems related to their use:
    • Pain
    • Oral Complications of Chemotherapy and Head/Neck Radiation
