Chronic lymphocytic leukemia (CLL) is the most common forms of leukemia in the western world and is characterized by a highly variable clinical course. Some patients live for many years without treatment, whereas other have disease with rapid progression.
The treatment of chronic lymphocytic leukemia has achieved extraordinary progress over the last years with the incorporation of monoclonal antibodies and combined chemoimmunotherapy. Despite these therapeutic successes, CLL is still considered to be an incurable disease.
