ERG and cancer: In the finasteride arm, the 90-day change in PCA3 and T2:ERG did not discriminate men with and without cancer (AUC 51% (95% CI 43 to 60%, p = 0.72) and 48% (95% CI 44 to 60%), respectively,) however, baseline and 90-day measures of PCA3 and T2:ERG were moderately predictive of cancer with AUCs ranging from 62 to 65% (p-values < 0.002 to <-0.001, Table 2) In the placebo arm, the baseline and 90-day AUCs of PCA3 were higher than the finasteride arm (84% and 80%, respectively, comparison to the finasteride arm, 65% and 63%, respectively).
