Detection of the SYT-SSX fusion transcripts in formaldehyde-fixed, paraffin-embedded tissue: a reverse transcription polymerase chain reaction amplification assay useful in the diagnosis of synovial sarcoma..     ///    Fifteen other sarcomas and related tumors were negative for SYT-SSX fusion transcripts.     ///    The SYT-SSX fusion transcripts were detected in 21 of the 22 analyzed cases.     ///    "In this study, we developed a polymerase chain reaction (PCR) assay to amplify SYT-SSX fusion transcripts. "    ///    The PCR products were confirmed as SYT-SSX sequences by sequencing in five randomly selected cases.
