Treatment Decision Tools Detailed Guide: Myelodysplastic Syndrome What Are Myelodysplastic Syndromes and Myelodysplastic/Myeloproliferative Diseases? What Are Myelodysplastic Syndromes? Myelodysplastic ( myelo – bone marrow, dysplastic – abnormal growth) syndromes are a group of conditions caused by abnormal blood-forming cells of the bone marrow. In myelodysplastic syndromes (MDS), the bone marrow cannot produce blood cells effectively. Many of the blood cells formed are defective. These abnormal blood cells are usually destroyed before they leave the bone marrow or shortly after entering the bloodstream. As a result, patients have shortages of blood cells, which are reflected in their low blood counts. Although MDS has not been considered cancer in the past, most hematologists (specialists in diseases of the blood) now think it is a form of cancer. The major reason is that it is considered a clonal disease . That means there is only a single population of abnormal cells. All the cells are exactly alike just like identical twins. This is often seen in cancer where all the cells appear to have started from an original abnormal cell. A second reason it is considered a form of cancer is that in about 30% of MDS cases, the abnormal bone marrow cells eventually progress into

Of course, these do not occur only with MDS and are more often caused by something other than cancer. Shortages of one or more types of blood cells can cause most signs and symptoms of MDS: Excessive tiredness, shortness of breath, and pale skin can be caused by anemia (shortage of red blood cells). Serious infections with high fevers can be caused by leukopenia (not having enough normal white blood cells) and, in particular, by having

References What are the myelodysplastic syndromes? The myelodysplastic syndromes are a group of disorders affecting the bone marrow. They are not types of cancer, although in a small number of people they can develop into a particular form of leukaemia. However, the symptoms are often very similar to those caused by cancer and the treatments used are also similar. back to top The bone marrow The bone marrow is the spongy material in the centre of some of our bones. It produces cells known as stem cells. Stem cells are immature cells that develop into the three different types of blood cells. Red blood cells, which carry oxygen to all cells in the body. White blood cells (including plasma cells), which are essential for fighting infections. Platelets, which help the blood to clot, to prevent bleeding. Myelodysplasia is an abnormality of the bone marrow which affects the production of healthy blood cells. There are five different types of myelodysplasia: refractory anaemia (RA) refractory anaemia with ring sideroblasts (RARS) refractory anaemia with excess blasts (RAEB) refractory anaemia with excess blasts in transformation (RAEB-t) chronic myelomonocytic leukaemia (CMML).

About 12,000 new cases of MDS are diagnosed in the United States each year. Although children and young adults can have MDS, most MDS patients are over age 60. About twice as many men as women have the disease. The cause of MDS is not known, but some studies have linked it to exposure to pesticides, herbicides and the chemical benzene, which is found in unleaded gasoline. MDS is sometimes called myelodysplasia, preleukemia or smoldering leukemia. These last two terms reflect the fact that MDS can sometimes turn into leukemia, most often acute myelogenous leukemia Healthy bone marrow makes cells that grow into the three types of blood cells: red blood cells, white blood cells and platelets. In people with MDS, instead of sending red blood cells, white blood cells and platelets into the blood stream, the marrow makes many immature blood cells called blasts. Not only do these blast cells not work normally as red blood cells, white blood cells or platelets, they can also collect in the bone marrow, damaging it even further. Symptoms and Diagnosis The most common symptom of MDS is anemia, or too few red blood cells. A patient with anemia feels tired, short of breath and is pale. In addition, MDS patients can have frequent infections because they have too few normal white blood cells and can bruise and bleed easily because they have too few platelets.

Medical Services Treatment of Myelodysplastic Syndromes at Mayo Clinic (Synonyms: myelodysplasia, refractory anemia, preleukemia, dysmyelopoietic syndrome) Mayo Clinic has been a world leader in the treatment of patients with bone marrow disorders, including myelodysplastic syndromes (MDS). Although myelodysplastic syndromes are relatively rare, Mayo Clinic physicians care for more than 1,600 patients with these syndromes each year. Patients with MDS face the risk that the disease will transform into leukemia, which can be difficult to treat. The chances of developing leukemia depend on the subtype of myelodysplastic syndromes and the specific genetic injury that occurred in the bone marrow cells. Most patients suffering from MDS live with complications from persistent low blood counts, including infection and bleeding. Diagnosis Many patients with myelodysplastic syndromes suffer from a variety of symptoms caused by low blood counts. Other patients have no symptoms at all. Physicians often detect MDS incidentally after performing a blood count for another reason. Hematologists diagnose MDS based on a careful review of the patient's blood under a microscope and a detailed clinical evaluation. An experienced hematopathologist also conducts a bone marrow biopsy. Careful analysis of the bone marrow chromosomes can reveal the MDS type and exclude other possible diseases. The diagnosis of MDS can be extremely difficult to make. Several other disorders can have similar blood counts and bone marrow appearance.

The myeloid disease group at Mayo Clinic includes basic scientists and clinicians. Because current MDS treatments are unable to cure the disease, Mayo researchers are committed to evaluating new drug therapies. Research efforts include on-site efforts, an ongoing collaboration with the University of Oxford in the United Kingdom and cooperation with researchers at other institutions. Drugs that appear promising in the laboratory and are expected to be relatively safe are tested in clinical trials through the Mayo Clinic Cancer Center. The available list of clinical trials (opens in new window) constantly changes. Decisions about participating in a clinical trial, supportive care or other therapy depends on individual circumstances and needs. Mayo Clinic hematologists provide in-depth consultations to help each patient make the best decisions for treatment.

Index Myelodysplastic Syndromes What are myelodysplastic syndromes? Myelodysplastic syndromes (MDS) are a group of diseases that affect the bone marrow and blood. Although children and young adults sometimes have MDS, most people with MDS are over 60 years old. MDS may also be called myelodysplasia or preleukemia. How does it occur? Healthy bone marrow produces stem cells, which can develop into 3 types of blood cells: red blood cells, white blood cells, and platelets. When the bone marrow malfunctions and the stem cells fail to mature fully, it is called MDS. The marrow of people with MDS produces too many immature blood cells called blasts. These blast cells cannot function properly as blood cells. They also collect in the bone marrow, damaging it further. What causes MDS is not known. It may be caused by exposure to pesticides, herbicides, and the chemical benzene, which is found in unleaded gasoline.

Other Resources Leukemia Myelodysplastic Syndromes Signs and Symptoms Diagnosis Treatment Signs and Symptoms Myelodysplastic syndromes, also called pre-leukemia or "smoldering" leukemia, are diseases in which the bone marrow the spongy tissue inside the large bones does not function normally. Bone marrow cells called "blast" develop or mature into several different types of blood cells including red blood cells that carry oxygen and other materials to all tissues of the body; white blood cells that fight infection; and platelets that make the blood clot. If cells in the bone marrow are injured or abnormal, they may behave abnormally. In myelodysplastic syndromes, the abnormality causes the bone marrow cells or blasts to develop into defective red cells, white cells and platelets. In acute myeloid leukemia, which is the more quickly advancing form of the disease, cells stop maturing altogether. Myelodysplastic syndromes or acute myeloid leukemia may arise without any known cause or may be due to prior treatment with drugs or radiation for other diseases. Myelodysplastic syndromes occur most often in older people, but they also occur in children and young people.
