ABSTRACT
<p><b>OBJECTIVE</b>To assess the value of multiprobe fluorescence in situ hybridization (FISH) panel in the diagnosis of acute myeloid leukemia (AML).</p><p><b>METHODS</b>The multiprobe AML/MDS panel comprising 8 different FISH probes for AML1/ETO transfusion gene, PML-RARα transfusion gene, CBFβ/MYH11 transfusion gene, MLL breakapart, P53 deletion, Del(5q), -7/Del(7q), and Del(20q) was tested in 40 cases of AML, and the results were compared with those by conventional cytogenetic G-banding (CCG) test.</p><p><b>RESULTS</b>With multiprobe FISH panel, 22 of the 40 AML cases were found to carry 7 types of cytogenetic abnormalities, namely AML1/ETO transfusion gene, PML-RARα transfusion gene, MLL breakapart, P53 deletion, Del(5q), -7/Del(7q) and trisomy 8. The positive ratio of the multiprobe FISH was 57.5%. CCG only identified 8 cases with the corresponding cytogenetic abnormalities and 3 cases with other cytogenetic abnormalities, and the positive ratio was only 27.50%.</p><p><b>CONCLUSION</b>Mutiprobe FISH panel is more rapid, accurate and effective than CCG in the diagnosis of AML.</p>
