Cytogenetic and molecular cytogenetic analysis of B cell chronic lymphocytic leukemia: specific chromosome aberrations identify prognostic subgroups of patients and point to loci of candidate genes. We analyzed this group of patients treated with FCR to characterize the relationship between clinico-biological parameters and outcome. The four most common chromosomal aberrations that are detected using FISH studies at diagnosis are: 1) Deletions on the long arm of chromosome 13 (del (13q14)) (present in 55%), 2) Deletions on the long arm of chromosome 11 (del (11q23)) (present in 18%), 4) Deletions on the short arm of chromosome 17 (del(17p)) (present in 7% at diagnosis). How do doctors diagnose chronic lymphocytic leukemia? CLL is not curable. a higher blood level of a protein called beta 2 microglobulin. For instance, patients who have a 13q deletion.
