Leukemia cells demonstrate clonal cytogenetic abnormalities in more than 85% of patients. These changes are often unique to the subtype. For example, the t(15;17) translocation is nearly always found in patients with APL, whereas t(8;21) is most commonly found in those with myeloblastic leukemia.

Some of the cytogenetic abnormalities have now been shown to confer either greater risk of recurrent disease (eg, monosomy 7 and monosomy 5) or lower risk (eg, t[8;21] and inv[16]/t[16;16]).
