BACKGROUND: An 11q22 deletion is considered an independent factor predicting poor survival in chronic lymphocytic leukemia (CLL). METHODS: We searched the electronic CLL database for consecutive patients who presented to the M. D. Anderson Cancer Center Department of Leukemia from October 2003 to April 2007 with untreated CLL and who had an 11q22 deletion, detected by fluorescence in situ hybridization (FISH) analysis of bone marrow samples. FISH analysis was performed using the following probes: trisomy 12 (12p11.1-q11), TP53 (17p13.1), ATM (11q22.3), LAMP1 (13q34), and D13S319 loci (13q14.3). RESULTS: Sixty-nine patients with untreated CLL with an 11q22 deletion were identified. The median..
