Chemoimmunotherapy of chronic lymphocytic leukemia

The past two decades have seen a major paradigm shift in the therapy of chronic lymphocytic leukemia (CLL), with the treatment goal shifting from symptom palliation to the attainment of maximal disease control using the most effective frontline regimens available, thus prolonging survival and possibly leading to cure. The most potent therapeutic regimens developed to date include the chemoimmunotherapy combinations incorporating purine analogs and monoclonal antibodies. We review the evolution of modern chemoimmunotherapy for CLL, and discuss current research directions for further refining the potency of these regimens.
