Myeloproliferative neoplasms (MPNs) are chronic disorders that cause excessive production of blood cells. These blood cells are formed in the bone marrow by hematopoietic “stem cells” that create all of the different blood cell types. These stem cells produce red blood cells, white blood cells, and platelets. Each of these blood components plays a different role, and in MPNs the ratio and number of the red blood cells, white blood cells and platelets is out of balance.

Conditions and Complications
The classic chronic myeloproliferative neoplasms (MPNs) are polycythemia vera (PV), essential thrombocythemia (ET), chronic myeloid leukemia (CML), and primary myelofibrosis (MF). There are also many complications common to patients with MPNs. Learn more about these conditions and the best ways to treat them.
Due to breakthrough research into the causes of myeloproliferative neoplasms (MPNs), treatment possibilities continue to expand. Learn more about the latest MPN treatment options.
