There are a few terms that often come up. No. 1 is “leukocytosis.” This often is a term that’s thrown around, especially in relation to myelofibrosis and also polycythemia vera, and this term means an elevated white blood cell count. That is a common thing that, as medical providers, we may just throw around in the room and not necessarily think about the fact that we should explain that a little bit better.
Additionally, “anemia” is a term very often used when talking about myelofibrosis, and that just means a decrease in red blood cells.
Often, people associate anemia with iron deficiency because this is probably the most common form of anemia, but as it relates to MPNs – and specifically, myelofibrosis – it is generally a problem with production that does not have anything to do with iron, but is actually more so just related to the disease and how the red blood cells are impaired because of the fibrosis of the bone marrow.
