SALVAGE RADIATION THERAPY FOR PROSTATE SPECIFIC ANTIGEN PROGRESSION FOLLOWING RADICAL PROSTATECTOMY: 10-YEAR OUTCOME ESTIMATES

An undetectable PSA level following salvage radiation therapy is more frequently achieved in men with lower pre-radiation serum PSA and those without seminal vesicle or lymph node involvement. Overall approximately a fourth of men with PSA evidence of cancer progression following RRP had a durable response 10 years after the initiation of salvage radiation therapy in the protocols used in this patient cohort.
