Chronic myeloid leukemia.

Chronic myeloid leukemia is one of the commonest hematological malignancies seen in clinical practice. It is the result of abnormal and excess cell proliferation due to de-regulated bcr-abl tyrosine kinase activity as a result of Philadelphia chromosome. The present article discusses the various options available to treat the disorder. Allogeneic stem cell transplant remains the gold standard and the only curative option. Hydroxyurea and Busulfan helps in controlling the total leukocyte count but fail to impact on survival. Interferon especially when combined with cytarabine is curative in minority of patients though a substantial number of patients achieve functional cure. Imatinib, a molecular targeted oral therapy, against bcr-abl tyrosine kinase is the latest addition to various treatment options. Early results appear very promising and can be considered as non- transplant standard of care.
