Chromosome 6q deletion correlates with poor prognosis and low relative expression of FOXO3 in chronic lymphocytic leukemia patients

Original language description

Detection of genetic changes has improved the current risk stratifica-tion in chronic lymphocytic leukemia (CLL).1,2Among the known recur-rent chromosomal abnormalities,16q deletion is less frequent andcontroversy surrounding its prognostic significance still remains.3,4The study aimed at a genetic analysis of a group of CLL patientswith chromosome 6q deletion for determination of its prognostic sig-nificance, extent, the minimal deleted region (MDR) using array com-parative genomic hybridization (arrayCGH), and finally to dermine therelative expression of candidate genes located therein.Peripheral blood and/or bone marrow samples from 1158 CLLpatients diagnosed and treated in three Czech hematology centers(Brno, Olomouc and Pilsen) were examined in 2001–2016 usingconventional cytogenetics (CG) and FISH. The patient characteristicsare listed in Supporting Information Table S1. Chromosome 6q dele-tion was found by CG (53) and FISH (38) in a total of 91 (7.9%)patients. Complete data and material for further analysis were avail-able for only 70 patients, including 42 patients examined at CLLdiagnosis and 28 treated patients examined in the course of the dis-ease (Table 1).Deletion 6q was confirmed as a single aberration in 10 patients,together with one additional aberration in 21 and as part of a complexkaryotype in 39 patients. Evaluation of the frequency of other changesusing a FISH CLL panel1showed that 13q deletion was the most fre-quent change regardless of the number of changes, occurring in 30/70(42.8%) patients. TP53 deletion was present in 17 (24.3%) patients,with 13 of them having a complex karyotype. The results concerningthe presence of additional changes identified by CG and FISH areshown in Supporting Information Figure S1
