Blood Review Series – Myeloproliferative Neoplasms

A small area of skin over your lower back pelvis is cleaned and numbed. Then a marrow needle is used to withdraw bone marrow. If a biopsy is performed, the doctor uses a different needle to remove a small piece of marrow from your bone a marrow core. In either case, the sample will be examined under a microscope to determine the presence and number of abnormal cells in your marrow and whether you have myelofibrosis. In addition, doctors will perform cytogenetic analysis. This means your marrow cells will be set up in a culture dish to make them divide. This will allow us to see your chromosomes under a microscope and tell whether any are abnormal. Doctors use the number and type of chromosome abnormalities to help predict how your disease will progress and which types of treatment might be most effective.

Your chromosomes contain your genes and can provide instructions for how your cells function. Fluorescent in situ hybridization FISH is a specialized cytogenetic analysis. The fluorescent dyes used in this test attach to specific parts of certain chromosomes. More chromosomal abnormalities can be seen under a microscope using this technique than with the standard technique described above.

Molecular studies are very sensitive, specific tests for gene mutations associated with different myeloproliferative processes. Your doctors will use these tests to look for one or more of the following mutations:. You may have flow cytometry a computer analysis of cells to tell how your disease is progressing. Exposure to toxins, such as benzene, certain solvents or pesticides, and heavy metals, such as mercury or lead, may be involved in the development of genetic changes in stem cells. It is extremely difficult, if not impossible, to establish a clear cause-and-effect relationship between those exposures and the development of MPN. MPN is seen in all age groups but is more common in middle age and older adults.

Very rarely, there can be clustering of cases in families that have an inherited genetic defect. Healthy blood-cell formation. The circulating cells perform important functions. RBCs carry oxygen throughout the body. WBCs fight infection. Platelets protect against easy bleeding by helping your blood to clot. Blood-cell formation in MPN. A high level of RBCs is called polycythemia. A high level of WBCs is called leukocytosis. A high level of platelets is called thrombocytosis.

High levels of blood cells cause some of the symptoms of MPN. Polycythemia vera PV , in which there are too many RBCs Essential thrombocythemia ET , in which there are too many platelets Primary myelofibrosis PMF , in which fibers and blasts abnormal stem cells build up in the bone marrow. Other types of MPN. Chronic myeloid leukemia, in which there are too many WBCs Chronic neutrophilic leukemia, in which there are too many white blood cells called neutrophils Chronic eosinophilic leukemia, not otherwise specified, in which there are too many white blood cells called eosinophils hypereosinophilia Mastocytosis, also called mast cell disease, in which there are too many mast cells, which are a type of immune system cell found in tissues, like skin and digestive organs, rather than in the bloodstream Myeloproliferative neoplasms, unclassifiable—meaning your MPN does not fit into one of the other types Myeloid and lymphoid neoplasms with eosinophilia and abnormalities of the PDGFRA, PDGFRB, and FGFR1 genes.

Symptoms Some people with myeloproliferative neoplasms MPN have no symptoms when their disease is diagnosed. Polycythemia vera PV symptoms. Symptoms of PV, in which there are too many RBCs, may include the following: A feeling of pressure or fullness below the ribs on the left side Headaches Double vision or seeing dark or blind spots that come and go Itching all over the body, especially after being in warm or hot water Reddened face that looks like a blush or sunburn Weakness Dizziness Weight loss for no known reason.

Essential thrombocythemia ET symptoms. Symptoms of ET, in which there are too many platelets, may include the following: Headaches Stroke symptoms Chest pains In some cases, bleeding. Primary myelofibrosis PMF symptoms. Symptoms of PMF, in which fibers and blasts abnormal stem cells build up in the bone marrow, may include the following: Weakness and fatigue from severe anemia Abdominal pain and fullness from enlarged spleen and liver.

Other complications may include the following: Scarring of the bone marrow, called myelofibrosis. Although you may associate the word neoplasm with cancer, it is not that clear cut. Neoplasm is defined as an abnormal growth of tissue caused by a mutation and can be classified as benign noncancerous , pre-cancerous, or cancerous malignant. At diagnosis, most myeloproliferative neoplasms are benign but over time may evolve into a malignant cancerous disease. This risk of developing cancer with these diagnoses underlines the importance of close follow-up with your hematologist. The classifications of myeloproliferative neoplasms has changed quite a bit over the last few years but we will review the general categories here.
