Background
In chronic leukemias, we see an accumulation of mature, mutated myeloid cells. The cells will undergo uncontrolled proliferation due to hyperactivated tyrosine kinases or other signaling pathway alterations.
- Chronic leukemias have a slow progression, and they can progress into acute leukemias (but not the other way around!)
- Incurable
- Mostly affect older patients.
Chronic myeloid leukemia
A clonal proliferation of pluripotent myeloid stem cells.
- Chronic = slow onset, of mature cells; myeloid = of the myeloid lineage; leukemia = cancer of the blood and bone marrow.
- Caused by t(9;22) Philadelphia chromosome (the
