Using the multiprobe AML/MDS panel designed to detect upto eight different FISH probes, which was for AML1/ETO transfusion gene, PML-RAR? transfusion gene, CBF?/MYH11 transfusion gene, MLL breakapart, P53 deletion,Del(5q), Del(7q), Del(20q), 40 cases of AML were investigated.     ///    "22 of the 40 AML cases were found to carry 7 types of cytogenetic abnormalities by multiprobe FISH panel including AML1/ETO transfusion gene, PML-RARa transfusion gene, MLL breakapart, P53 deletion, Del (5q), Del7q and trisomy 8. "    ///    "Patiens with AML1/ETO or PML-RARa transfusion gene are easily to reach CR in the first induction chemotherapy, while the Del(7q), MLL breakapart, complex cytogenetic abnormalities may indicate poor prognosis.
