Treatment Option Overview
There are different types of treatment for patients with myelodysplastic/myeloproliferative neoplasms.
Different types of treatments are available for patients with myelodysplastic/myeloproliferativeneoplasms. 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.
Five types of standard treatment are used:
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. Combination chemotherapy is treatment using more than one anticancer drug.
See Drugs Approved for Myeloproliferative Disorders for more information.
Other drug therapy
13-cis retinoic acid is a vitamin-like drug that slows the cancer's ability to make more cancer cells and changes the way these cells look and act.
Stem cell transplant
Stem cell transplant is a method of replacing blood-forming cells that are destroyed by chemotherapy. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor 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.
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.
Supportive care is given to lessen the problems caused by the disease or its treatment. Supportive care may include transfusiontherapy or drug therapy, such as antibiotics to fight infection.
