Chronic Myeloproliferative Neoplasms

Myeloproliferative neoplasms are a group of diseases in which the blood stem cells of the bone marrow make too many red blood cells, white blood cells, or platelets. The neoplasms usually get worse slowly as the number of extra blood cells increases.

There are 6 types of chronic myeloproliferative neoplasms. The type of myeloproliferative neoplasm is based on whether too many red blood cells, white blood cells, or platelets are being made. Sometimes the body will make too many of more than one type of blood cell, but usually one type of blood cell is affected more than the others. The 6 types of chronic myeloproliferative neoplasms include:

  • Chronic myelogenous leukemia.
  • Polycythemia vera.
  • Primary myelofibrosis (also called chronic idiopathic myelofibrosis).
  • Essential thrombocythemia.
  • Chronic neutrophilic leukemia.
  • Chronic eosinophilic leukemia.
