                    There are different types of treatment for patients with plasma cell neoplasms.
                    Different types of treatments are available for patients with plasma cell neoplasms. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
                
                
                    Eight types of treatment are used:
                    Chemotherapy     Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.    See Drugs Approved for Multiple Myeloma and Other Plasma Cell Neoplasms for more information.       Other drug therapy     Corticosteroids are steroids that have antitumor effects in multiple myeloma.        Targeted therapy     Targeted therapy is a treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Several types of targeted therapy may be used to treat multiple myeloma and other plasma cell neoplasms.     Proteasome inhibitor therapy is a type of targeted therapy that blocks the action of proteasomes in cancer cells and may prevent the growth of tumors. Bortezomib, carfilzomib, ixazomib, daratumumab, and elotuzumab are proteasome inhibitors used in the treatment of multiple myeloma and other plasma cell neoplasms.     Histone deacetylase (HDAC) inhibitor therapy is a type of targeted therapy that blocks enzymes needed for cell division and may stop the growth of cancer cells. Panobinostat is an HDAC inhibitor used in the treatment of multiple myeloma and other plasma cell neoplasms.    See Drugs Approved for Multiple Myeloma and Other Plasma Cell Neoplasms for more information.       High-dose chemotherapy with stem cell transplant    This treatment is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient (autologous transplant) or a donor (allogeneic transplant) and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells.           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.     Immunomodulators are a type of biologic therapy. Thalidomide, lenalidomide, and pomalidomide are immunomodulators used to treat multiple myeloma and other plasma cell neoplasms.     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. External radiation therapy is used to treat plasma cell neoplasms.       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 patients condition without giving any treatment until signs or 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 website.     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 high-dose chemotherapy followed by stem cell transplant using the patient's own stem cells.    -  Biologic therapy: Biologic therapy with thalidomide, lenalidomide, or pomalidomide is given to treat amyloidosis.    -  Targeted therapy: Targeted therapy with proteasome inhibitors is given to treat amyloidosis.    -  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:               - Cancer Pain      - Oral Complications of Chemotherapy and Head/Neck Radiation
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
                
                
                    Follow-up tests may be needed.
                    Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.   Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

		                    Multiple Myeloma
		                    Patients without signs or symptoms may not need treatment. When signs or symptoms appear, the treatment of multiple myeloma may be done in phases:         -   Induction therapy : This is the first phase of treatment. Its goal is to reduce the amount of disease, and may include one or more of the following:               -  Corticosteroid therapy.      -  Biologic therapy with lenalidomide, pomalidomide, or thalidomide therapy.      -  Targeted therapy with proteasome inhibitors (bortezomib, carfilzomib, ixazomib, daratumumab, and elotuzumab).      -  Chemotherapy.      -  Histone deacetylase inhibitor therapy with panobinostat.      - A clinical trial of different combinations of treatment.             -   Consolidation chemotherapy : This is the second phase of treatment. Treatment in the consolidation phase is to kill any remaining cancer cells. High-dose chemotherapy is followed by either:               - one autologous stem cell transplant, in which the patient's stem cells from the blood or bone marrow are used; or      - two autologous stem cell transplants followed by an autologous or allogeneic stem cell transplant, in which the patient receives stem cells from the blood or bone marrow of a donor; or      - one allogeneic stem cell transplant.             -   Maintenance therapy : After the initial treatment, maintenance therapy is often given to help keep the disease in remission for a longer time. Several types of treatment are being studied for this use, including the following:               - Chemotherapy.      -  Biologic therapy with interferon.      - Corticosteroid therapy.      - Lenalidomide therapy.      - Targeted therapy with a proteasome inhibitor (bortezomib).
