Nested RT-PCR and direct DNA sequencing were used to detect the fusion genes of TMPRSS2/ERG, TMPRSS2/ETV1, and TMPRSS2/ETV4.     ///    TMPRSS2/ERG and TMPRSS2/ETV1 fusion genes may be used as diagnostic tools for PCa..     ///    "TMPRSS2/ETV1 fusion was detected in only 2 cases (6.3%), including one newly discovered variant fusion transcripts with the GenBank accession number of EU090249. "    ///    The positive rates of TMPRSS2/ERG and TMPRSS2/ETV1 fusions showed no statistical association with the Gleason grade (P = 0.169).
