To determine whether adding the Decipher genomic classifier, a validated metastasis risk–prediction model, to standard risk-stratification tools (CAPRA-S and Stephenson nomogram) improves accuracy in predicting metastatic disease within 5 yr after surgery (rapid metastasis [RM]) in an independent cohort of men with adverse pathologic features after radical prostatectomy (RP).

The study population consisted of 169 patients selected from 2641 men who underwent …
