Molecular genetic analyses of the TMPRSS2-ERG and TMPRSS2-ETV1 gene fusions in 50 cases of prostate cancer..     ///    "Herein, we have analyzed a series of 50 prostate cancer samples for expression of TPRSS2-ERG and TMPRSS2-ETV1 fusion transcripts. "    ///    Our findings show that the TMPRSS2-ERG fusion is common in prostate cancer and that the related TMPRSS2-ETV1 fusion is very rare.     ///    None of the tumors expressed a TMPRSS2-ETV1 fusion.
