A type of leukaemia, also called chronic granulocytic leukaemia, which is caused by the overproduction of granulocytes, neutrophils, or polymorphonuclear leukocytes (see blood cells). The cause is unknown. This type of leukaemia usually has 2 phases: a chronic phase, which may last for several years, and a more cancerous phase, which is known as the blastic, accelerated, or acute phase. During the chronic phase, symptoms may include fever, night sweats, and weight loss. Visual disturbances, abdominal pain, and priapism may also occur. The symptoms of the more cancerous phase are like those of the acute forms of leukaemia (see leukaemia, acute). The diagnosis is made from blood tests and a bone marrow biopsy. Treatment of the chronic phase includes anticancer drugs. When the disease transforms into the acute phase, treatment is similar to that given for acute leukaemia.
