We tested the prognostic utility of a three-marker fluorescent in situ hybridization (FISH) panel (TMPRSS2/ERG rearrangements, AR gain, and PTEN deletion) in a retrospective cohort (n = 210.     ///    "First, PTEN deletion without TMPRSS2/ERG rearrangement was enriched in pT3/4 tumors (70% versus 48%) and tumors with Gleason grades of 8 to 9 (60% versus 17%) compared with the entire cohort. "    ///    "Second, AR gain and concurrent trisomy 10 without TMPRSS2/ERG rearrangement were enriched in pT3/4 tumors and tumors with Gleason grades of 8 to 9. "
