Myelodysplastic/ Myeloproliferative Neoplasms Treatment (PDQ®): Treatment - Patient Information [NCI] - Myelodysplastic / Myeloproliferative Neoplasm, Unclassifiable

Myelodysplastic/myeloproliferative neoplasm, unclassifiable, is a disease that has features of both myelodysplastic and myeloproliferative diseases but is not chronic myelomonocytic leukemia, juvenile myelomonocytic leukemia, or atypical chronic myelogenous leukemia.

In myelodysplastic /myeloproliferative neoplasm, unclassifiable (MDS/MPD-UC), the body tells too many blood stem cells to become red blood cells, white blood cells, or platelets. Some of these blood stem cells never become mature blood cells. These immature blood cells are called blasts. Over time, the abnormal blood cells and blasts in the bone marrow crowd out the healthy red blood cells, white blood cells, and platelets.
