Chromosome aberrations are frequently found in B‐cell chronic lymphocytic leukaemia (B‐CLL), and specific chromosome aberrations identify poor prognostic subgroups. Almost all the aberrations identified in B‐CLL involve loci where genes with a role in the regulation of centrosome duplication have been mapped. Centrosome aberrations have been described as a possible cause of numerical chromosome abnormalities in both solid and haematological tumours. However, little is known about the possible role of centrosome aberrations in B‐CLL. To investigate whether centrosome aberrations do occur in B‐CLL and correlate with cytogenetically defined prognostic subgroups, we examined a set of 64 B‐CLL samples by immunofluorescent staining. B‐CLL cases differed significantly from controls in the mean frequency of cells with centrosome aberrations, while no difference was found between subgroups with or without specific chromosome aberrations. Our results indicated that although centrosome aberrations were a common feature in B‐CLL, they did not represent a reliable prognostic marker. Copyright © 2007 John Wiley & Sons, Ltd.
