Chronic Myeloid Leukaemia
Chronic myeloid leukaemia (CML) is a slowly developing cancer of white blood cells that begins in blood stem cells within the bone marrow. It often causes no symptoms early on and may be found by chance on a routine blood test.
Key points
- More than 95 percent of people with CML carry the Philadelphia chromosome, a genetic change that produces an abnormal protein driving disordered white blood cell growth.
- CML progresses through three phases: chronic, accelerated, and blast, and most people are diagnosed while still in the chronic phase.
- For most people, CML can be well controlled for as long as treatment continues, and most people with CML have a normal life expectancy.
Medicines listed for Chronic Myeloid Leukaemia
The listed products for chronic myeloid leukaemia span two broad medicine classes. Imatinib and dasatinib are tyrosine kinase inhibitors, a group that targets the abnormal protein produced by the Philadelphia chromosome. Hydroxycarbamide is a cytostatic agent that reduces the number of abnormal white blood cells in the blood and bone marrow. Gleevec and Hydrea are supplied as tablets; Sprycel comes in a bottle.
