Multiple myeloma treatment options
People with multiple myeloma have many treatment options. The options are active surveillance, induction therapy and stem cell transplant. Sometimes a combination of methods is used.
Radiation therapy is used sometimes to treat painful bone disease. It may be used alone or along with other therapies. See the Comprehensive care section to learn about ways to get support for relieving your pain.
The choice of treatment depends mainly on how advanced the disease is and whether you have symptoms. If you have multiple myeloma without symptoms (smoldering myeloma), you may not need cancer treatment right away. The doctor monitors your health closely (active surveillance) so that treatment can start when you begin to have symptoms.
If you have symptoms, you will likely get induction therapy. Sometimes a stem cell transplant is part of the treatment plan.
When treatment for myeloma is needed, it can often control the disease and its symptoms. People may receive therapy to help keep the cancer in remission, but myeloma can seldom be cured. Because standard treatment may not control myeloma, you may want to talk to your doctor about taking part in a clinical trial. Clinical trials are research studies of new treatment methods.
People with smoldering myeloma or Stage I myeloma may be able to put off having cancer treatment. By delaying treatment, you can avoid the side effects of treatment until you have symptoms.
If you and your doctor agree that active surveillance is a good idea, you will have regular checkups (such as every three months). You will receive treatment if symptoms occur.
Although active surveillance avoids or delays the side effects of cancer treatment, this choice has risks. In some cases, it may reduce the chance to control myeloma before it gets worse.
You may decide against active surveillance if you don’t want to live with untreated myeloma. If you choose active surveillance but grow concerned later, you should discuss your feelings with your doctor. Another approach is an option in most cases.
Many different types of drugs are used to treat myeloma. People often receive a combination of drugs, and many different combinations are used to treat myeloma.
Each type of drug kills cancer cells in a different way:
- Chemotherapy: Chemotherapy kills fast-growing myeloma cells, but the drug can also harm normal cells that divide rapidly.
- Targeted therapy: Targeted therapies use drugs that block the growth of myeloma cells. The targeted therapy blocks the action of an abnormal protein that stimulates the growth of myeloma cells.
- Steroids: Some steroids have antitumor effects. It is thought that steroids can trigger the death of myeloma cells. A steroid may be used alone or with other drugs to treat myeloma.
You may receive the drugs by mouth or through a vein (IV). The treatment usually takes place in an outpatient part of the hospital, at your doctor’s office, or at home. Some people may need to stay in the hospital for treatment.
Stem cell transplant
Many people with multiple myeloma may get a stem cell transplant. A stem cell transplant allows you to be treated with high doses of drugs. The high doses destroy both myeloma cells and normal blood cells in the bone marrow. After you receive high-dose treatment, you receive healthy stem cells through a vein. (It’s like getting a blood transfusion.) New blood cells develop from the transplanted stem cells. The new blood cells replace the ones that were destroyed by treatment.
Stem cell transplants take place in the hospital. Some people with myeloma have two or more transplants.
Stem cells may come from you or from someone who donates their stem cells to you:
- From you: An autologous stem cell transplant uses your own stem cells. Before you get the high-dose chemotherapy, your stem cells are removed. The cells may be treated to kill any myeloma cells present. Your stem cells are frozen and stored. After you receive high-dose chemotherapy, the stored stem cells are thawed and returned to you.
- From a family member or other donor: An allogeneic stem cell transplant uses healthy stem cells from a donor. Your brother, sister, or parent may be the donor. Sometimes the stem cells come from a donor who isn’t related. Doctors use blood tests to be sure the donor’s cells match your cells. Allogeneic stem cell transplants are under study for the treatment of multiple myeloma.
- From your identical twin: If you have an identical twin, a syngeneic stem cell transplant uses stem cells from your healthy twin.
There are two ways to get stem cells for people with myeloma. They usually come from the blood (peripheral blood stem cell transplant) or from bone marrow (bone marrow transplant).
After a stem cell transplant, you may stay in the hospital for several weeks or months. You’ll be at risk for infections because of the large doses of chemotherapy you received. In time, the transplanted stem cells will begin to produce healthy blood cells.
