Chronic Myeloproliferative Disorders Treatment (PDQ®): Treatment - Patient Information [NCI] - Polycythemia Vera
Polycythemia vera is a disease in which too many red blood cells are made in the bone marrow.
In polycythemia vera, the blood becomes thickened with too many red blood cells. The number of white blood cells and platelets may also increase. These extra blood cells may collect in the spleen and cause it to swell. The increased number of red blood cells or platelets in the blood can cause bleeding problems and make clots form in blood vessels. This can increase the risk of stroke or heart attack. In patients who are older than 65 years or who have a history of blood clots, the risk of stroke or heart attack is higher. Patients also have an increased risk of acute myeloid leukemia or primary myelofibrosis.
A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your child's doctor for clinical trials that are not listed here but may be right for your child.
Newly Diagnosed Childhood Acute Myeloid Leukemia
Treatment of newly diagnosed childhood acute myeloid leukemia may include the following:
Combination chemotherapy plus central nervous system sanctuary therapy with intrathecal...
Possible signs of polycythemia vera include headaches and a feeling of fullness below the ribs on the left side.
Polycythemia vera often does not cause early symptoms. It is sometimes found during a routine blood test. Symptoms may occur as the number of blood cells increases. Other conditions may cause the same symptoms. Check with your doctor if you have any of the following problems:
A feeling of pressure or fullness below the ribs on the left side.
Special blood tests are used to diagnose polycythemia vera.
In addition to a complete blood count, bone marrow aspiration and biopsy, and cytogenetic analysis, a serum erythropoietin test is used to diagnose polycythemia vera. In this test, a sample of blood is checked for the level of erythropoietin (a hormone that stimulates new red blood cells to be made).
