Myeloproliferative Neoplasms (MPNs)

Myeloproliferative neoplasms (MPNs) are a closely related group of progressive blood cancers in which the bone marrow typically overproduces one of the mature blood elements. Other shared features include tendencies toward blood clotting/bleeding, organ enlargement, bone marrow scarring (fibrosis) and a possibility of transformation.

There are three blood cancer types that are categorized as “classic” MPNs:

  • Primary Myelofibrosis (MF)
  • Essential Thrombocythemia (ET)
  • Polycythemia Vera (PV).
