TMPRSS2/ERG and TMPRSS2/ETV1 fusion genes may be used as diagnostic tools for PCa..     ///    "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 TMPRS22/ETV1 fusion genes with different subtypes exist in the tissues of PCa.     ///    The positive rates of TMPRSS2/ERG and TMPRSS2/ETV1 fusions showed no statistical association with the Gleason grade (P = 0.169).
