Chronic lymphocytic leukaemia (CLL) results from the expansion of a clone of CD5+ B lymphocytes with distinct morphology and membrane antigens. The clinical course is variable and is determined by the stage of the disease. Genetic abnormalities detected by fluorescence in situ hybridization (FISH) analysis are important determinants of prognosis. Treatment is only indicated in symptomatic patients with active disease.
