Chronic myeloid leukemia (CML, also known as chronic myelocytic or chronic myelogenous leukemia) is classified as one of the myeloproliferative neoplasms, along with polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). (See "Overview of the myeloproliferative neoplasms".)

This group of diseases shares several distinct features:

They are clonal disorders of hematopoiesis that arise in a hematopoietic stem or early progenitor cell.

They are characterized by the dysregulated production of a particular lineage of mature myeloid cells with fairly normal differentiation.

They exhibit a variable tendency to progress to acute leukemia.
