Myeloid Leukemia, Chronic (C0023473)

Definition (MEDLINEPLUS)

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic myeloid leukemia (CML), there are too many granulocytes, a type of white blood cell.

Most people with CML have a gene mutation (change) called the Philadelphia chromosome.

Sometimes CML does not cause any symptoms. If you have symptoms, they may include:

  • Fatigue
  • Weight loss
  • Night sweats
  • Fever
  • Pain or a feeling of fullness below the ribs on the left side

Tests that examine the blood and bone marrow diagnose CML. Treatments include chemotherapy, stem cell transplants, infusion of donated white blood cells following stem cell transplants, surgery to remove the spleen, and biologic and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.

NIH: National Cancer Institute
Definition (NCI_NCI-GLOSS) A slowly progressing disease in which too many white blood cells are made in the bone marrow.
Definition (NCI) A chronic myeloproliferative neoplasm characterized by the expression of the BCR-ABL1 fusion gene. It presents with neutrophilic leukocytosis. It can appear at any age, but it mostly affects middle aged and older individuals. Patients usually present with fatigue, weight loss, anemia, night sweats, and splenomegaly. If untreated, it follows a biphasic or triphasic natural course; an initial indolent chronic phase which is followed by an accelerated phase, a blast phase, or both. Allogeneic stem cell transplantation and tyrosine kinase inhibitors delay disease progression and prolong overall survival.
Definition (CSP) chronic leukemia in which myeloid progenitor cells predominate; the hallmark of CML, the Philadelphia chromosome, is a reciprocal translocation between chromosomes 9 and 22 which activates the proto- oncogene c-abl.
Definition (MSH) Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.
