The objective of this work is to study CLL chronic lymphocytic leukemia and the different diagnostic methods based on symptoms and prognostic factors. The importance of karyotype cytogenetic analysis and FISH for the detection of different chromosomal abnormalities to classify patients according to their unfavorable profile.
