title: Parameters for treatment decisions for salvage radiation therapy.
abstract: Radical prostatectomy (RP) is the most common primary treatment for prostate cancer. About 40% of those with high-risk pathologic features, such as a positive margin or seminal vesicle involvement, will develop biochemical failure at some point in the future. Radiotherapy (RT), with or without concurrent androgen deprivation, has been used liberally in the management of men with a rising prostate-specific antigen (PSA) after RP, based mostly on relatively small retrospective series. Factors such as the prostatectomy Gleason score, seminal vesicle invasion, absolute pre-RT PSA level, and pre-RT PSA doubling time are emerging as important determinants of outcome after RT. These factors should be used as a guide to the options of local therapy alone (RT), local therapy plus systemic therapy (typically androgen deprivation therapy), and systemic therapy alone.
