Chronic Lymphocytic Leukemia and Associated Disorders
April 01, 2005
Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the Western hemisphere, accounting for 30% of the leukemias in this population. The disease results from a clonal expansion of small B-lymphocytes. CLL always involves the bone marrow and peripheral blood. The disease also can be demonstrated in lymph nodes, liver, and spleen.
