[Epidemiologic, clinical and therapeutic aspects of chronic lymphoid leukemia: apropos of 120 cases].

We retrospectively studied 120 cases of chronic lymphocytic leukemia diagnosed between January 1988 and December 1998. The median age of our patients was of 66 years, 75% among them were male. The discovery of the illness was fortuitous in 20% of the cases, the peripheral adenopathy and the splenomegaly were noted respectively in 72 and 48% of the cases. The blood lymphocytosis was on average 51.109/1 with extremes of 5 and 818.109/1. Anemia was noted in 71% of the cases and a thrombopenia in 42%. Fifty patients were classified C stage of BINET and sixty elevated risk according to RAI. The therapeutic attitude was according to patient's age and the CLL stage. Thus, 94 patients received a chemotherapy and a complete or partial response was observed in 58 of the cases. The overall survival at 5 years were 47%. The retained prognostic factors were the stage according to the classifications of BINET and RAI, the thrombopenia and the lymphocytosis blood overhead 100.109/1.
