Managing Cancer Relapse After Radical Prostatectomy: Adjuvant Versus Salvage Radiation Therapy.

An increasing proportion of men are undergoing radical prostatectomy for locally advanced prostate cancer. More than half of men with adverse pathologic features are expected to experience disease recurrence within 10 years. This article discusses the use of postoperative radiation therapy to decrease this risk. Evidence from 3 randomized trials and multiple retrospective studies indicates that either adjuvant or salvage radiation improve biochemical progression-free survival and may improve overall survival. Novel imaging and genomic analysis can improve patient selection for either modality, however current tests are unable to identify all patients who may benefit from additional local therapy.
