Sequence analysis of the resulting PCR fragments revealed EWS/FLI-1 fusion transcriptions of varying length.     ///    "To investigate the usefulness of reverse transcriptase polymerase chain reaction (RT-PCR) as an ancillary method for cytodiagnosis, we tested archival aspirates derived from ES patients to establish whether any beta-actin RNA expression or tumor-specific EWS/FLI-1 gene translocation had occurred.
