Chronic lymphocytic leukemia (CLL) is a disease characterized by an accumulation of mature malignant B lymphocytes in the peripheral blood, bone marrow, and lymph nodes. Diagnosis of CLL is defined by an absolute B lymphocyte count of at least 5,000 cells per microliter for three months. CLL represents the most common form of leukemia in Western countries, and predominantly affects older individuals; in the US, the median age at diagnosis is 72 years.
