Taken together with the detection of CBF beta - MYH11 transcripts in the absence of apparent chromosome 16 abnormalities by classical banding techniques, these data show that additional screening by either RT-PCR or FISH should be performed in all AML M4 , regardless of morphologic features, to allow accurate evaluation of the prognostic importance of this fusion transcript .
