About Polycythemia Vera

Polycythemia Vera (PV) is a rare cancer of the blood-building stem cells in the bone marrow resulting in a chronic increase of red blood cells, white blood cells and platelets. This condition increases the risk for circulatory disorders such as thrombosis and embolism, its symptoms lead to a reduced quality of life and on the long run may progress to myelofibrosis or transform to leukemia. While the molecular mechanism underlying PV is still subject of intense research, current results point to blood-building stem cells in the bone marrow with a set of acquired mutations, the most important being a mutant form of JAK2 that make up the malignant clone. Important PV treatment goals are to achieve healthy blood counts (hematocrit below 45%), improve quality of life and to slow or delay the progression of disease.
