Differences in Frequency of ERG Oncoprotein Expression Between Index Tumors of Caucasian and African American Patients With Prostate Cancer

ERG typing of CaP established a major difference between the index tumors of Caucasian and African American patients. ERG-negative index tumors might indicate a less favorable outcome for African American patients. The results of the present study underscore that typing of CaP for the ERG could enhance our understanding of the biologic differences between the examined ethnic groups.
