TMPRSS2-ERG gene fusion prevalence and class are significantly different in prostate cancer of Caucasian, African-American and Japanese patients..     ///    Future studies of the molecular pathways implicated in TMPRSS2-ERG gene fusion may shed light on the disparity in prevalence and mortality of PCa among different ethnic groups and help design better prevention and treatment strategies..     ///    "A multivariate analysis demonstrated that TMPRSS2-ERG gene fusion correlated with the ethnicity (P=0.03), marginally correlated with the pathologic stage (P=0.06), but not other clinicopathologic parameters, including age, preoperative PSA levels, and Gleason score. "    ///    "We examined the prevalence and class of TMPRSS2-ERG gene fusion in PCa from Caucasian, African-American, and Japanese patients. "    ///    "TMPRSS2-ERG gene fusion was present in 50% (21/42) of Caucasians, 31.3% (20/64) of African-Americans, and 15.9% (7/44) of Japanese (P=0.003).
