Molecular genetic analysis for the presence of EWS/FLI-1 fusion transcripts by the reverse transcriptase-polymerase chain reaction has recently been applied to peripheral PNETs.     ///    "In the present study, we analyzed eight central PNETs by reverse transcriptase-polymerase chain reaction for EWS/FLI-1 fusion transcripts. "    ///    Reverse transcriptase-polymerase chain reaction analysis of EWS/FLI-1 fusion transcripts provides a novel adjunctive tool in the differentiation of central versus peripheral PNET..
