title: Chronic myelogenous leukemia: molecule to man.
abstract: Chronic myelogenous leukemia (CML) is the best understood human cancer. The molecular basis of CML involves activation of a cellular proto-oncogene--ABL. The consequence is to increase tyrosine kinase activity. This results in a marked clonal increase in the myeloid mass. Later on, cellular maturation is blocked and the decrease eventuates in acute leukemia. Abnormalities of other proto-oncogenes or antioncogenes, like P53, may be involved in leukemia progression. Treatment of CML involves chemotherapy and, more recently, interferon. Whether this treatment prolongs survival or increases the likelihood of cure is unknown but either result seems unlikely. Bone marrow transplants which cure about 50% of persons with CML are most effective when performed in chronic phase.
