Abstract

Background Chromosome 17 abnormalities are associated with poor outcome in leukemias including AML. Recently, MK was introduced as an independent predictor of dismal outcome in AML. The additional prognostic effect of C17 abns in patients with MK in a CK background is not clear. Patients and Methods We conducted a retrospective analysis of 1086 patients with newly diagnosed AML treated between January 1998 and December 2007. Patients received treatment with one of the institution's first-line protocols. Results Four hundred eighty-three patients had CK. Among them, 370 patients (77%) had CK-MK, and 195 patients (53%) had CK-MK-C17 abns. Patients with CK-MK had significantly shorter OS rates compared with patients with CK without MK (4.4 vs. 8 months, respectively; P =.002). The median OS for patients with CK-C17 abns was shorter than for patients without C17 abns (4 vs. 6.1 months, respectively; P =.004). In a multivariate analysis, the presence of MK among patients with CK was identified as an independent prognostic marker for OS. In addition, presence of C17 abns had a significant negative effect on OS among patients with CK-MK (P =.04). Conclusion Among patients with CK-AML, MK was associated with poor outcomes. Additional presence of C17 abns further worsens the outcome in these particularly poor-risk patients with AML.
