The clinical course of chronic lymphocytic leukemia (CLL) is variable. Staging systems define high risk groups, such as patients with Rai's Stage III and IV and Binet's stage C disease, as having a poor overall median survival. Most combination therapy programs have resulted in similar results. Chlorambucil remains the most commonly used drug, and new drugs, such as fludarabine, are promising.
