Overview

Chromosomal aberrations have important prognostic significance in patients with chronic lymphocytic leukemia. Aberrations detected by fluorescence in situ hybridization define specific subgroups that differ in the overall survival and the time from diagnosis to first treatment. Patients with deletion 17p appear resistant to standard chemotherapy regimens and detection of this cytogenetic abnormality may influence therapeutic decisions. Because additional genetic defects (clonal evolution) may be acquired during the course of the disease, cytogenetic analysis is recommended not only at diagnosis, but prior every line of the treatment.

Key words:
chronic lymphocytic leukemia, chromosomal aberations, clonal evolution
