Objective:
To evaluate the value of spectral karyotyping (SKY) in cytogenetic analysis of acute myeloid leukemias (AML).
Methods:
Nine AML patients were analyzed by R-banding and SKY. MLL, PML-RARalpha, AML1-ETO fusion genes were detected by dual fusion- fluorescence in situ hybridization (D-FISH).
Results:
All 9 samples were successfully hybridized. SKY identified structural aberrations including 9q -, t(15;17) and ins(10;17) (q22;p11p12) ; and some numeral abnormalities. The results of SKY confirmed those of R-band karyotyping and D-FISH; with more accurate localization.
Conclusion:
SKY appears to be fairly stable, accurate and sensitive, for AML cytogenetic study.
