Utilization of a Genomic Classifier for Prediction of Metastasis Following Salvage Radiation Therapy after Radical Prostatectomy

To test whether a genomic classifier (GC) predicts development of metastatic disease in patients treated with salvage radiation therapy (SRT) after radical prostatectomy (RP). 70 primary prostate cancer tumor (radical prostatectomy, FFPE) specimens from patients at the Durham VA who recieved post-RP radiation therapy.
