Nine different EWSR1-FLI1 fusion transcripts and one EWSR1-ERG fusion transcript were identified in 21 out of 23 fresh frozen EFT tissue samples.    ///    Here we present a retrospective study designed to detect all of the EWSR1-FLI1 and EWSR1-ERG fusion transcripts in a series of 23 fresh frozen EFT tissues.     ///    RT-PCR and nested fluorescent multiplex PCR were used to amplify EWSR1-FLI1 and EWSR1-ERG transcripts from EFT tissues.
